How Many Teeth Do Maltese Dogs Have: Puppies In General Baby

Is your Maltese puppy sporting a “double row” of teeth, or are you wondering if your adult dog is missing a molar? For toy breeds, the gap between a standard dental formula and a tiny jaw creates a unique set of oral health challenges that can lead to lifelong pain if ignored. This guide provides the exact tooth counts, developmental timelines, and professional care strategies you need to ensure your Maltese keeps a healthy, pain-free smile.

Key Takeaways

  • The Magic Numbers: Adult Maltese dogs have exactly 42 permanent teeth; puppies start with 28 deciduous (baby) teeth.
  • The Toy Breed Paradox: While they have the same number of teeth as a Great Dane, the Maltese has a fraction of the jaw space, making retained baby teeth extremely common.
  • Critical Window: If baby teeth are still present by 6–7 months, professional extraction is usually mandatory to prevent permanent malocclusion.
  • Safety First: Never use human toothpaste (due to Xylitol and fluoride) or attempt “home extractions,” which can cause jaw fractures or root infections.
  • Gold Standard Care: Daily brushing with enzyme-based toothpaste combined with professional scaling every 12–18 months is the only way to combat the high rate of periodontal disease in small breeds.

How Many Teeth Do Maltese Dogs Have

Adult Maltese dogs have exactly 42 permanent teeth. It is a common misconception that smaller dogs have fewer teeth than larger breeds. In reality, the canine dental formula is a biological constant across the species Canis familiaris. Whether you own a 5-pound Maltese or a 150-pound Mastiff, the blueprint for the adult mouth is identical.

For a new Maltese owner, the first dental assessment should happen around eight weeks of age. At this stage, your puppy is in the heart of its deciduous phase. A veterinarian will perform a “count and check,” ensuring that the 28 baby teeth are erupting normally and that the jaw is symmetrical.

However, while the count is consistent, the fit is not. This is where genetics play a pivotal role. The Maltese is bred for a compact, brachycephalic-leaning skull. This genetic predisposition often results in a jaw that is numerically “too small” for the 42 teeth it must eventually house. When 42 permanent teeth compete for a tiny amount of real estate, the result is overcrowding. This crowding doesn’t change the number of teeth, but it creates “plaque traps”—tight spaces where food and bacteria lodge, making the Maltese significantly more prone to early-onset decay than larger breeds.

What Does A Maltese Teeth Diagram Reveal About Their Bite

If you were to look at a professional Maltese teeth diagram, you would see a highly specialized toolkit designed for an omnivorous diet. The 42 teeth are divided into four distinct types:

  1. Incisors (12 total): The tiny front teeth used for nibbling and grooming.
  2. Canines (4 total): The long “fangs” used for gripping and tearing.
  3. Premolars (16 total): The shearing teeth used to break down food.
  4. Molars (10 total): The heavy-duty grinders at the back of the mouth.

Proper bite alignment, or occlusion, is the goal of every dental assessment. In a healthy Maltese, the upper incisors should slightly overlap the lower incisors (a “scissor bite”). More importantly, the lower canines must fit precisely into the diastema—the natural gap between the upper third incisor and the upper canine.

When a dental diagram is compared to a real-life Maltese mouth, vets look for “malocclusions.” In toy breeds, the most common issue is a “crossbite” or “underbite,” where the lower jaw extends past the upper. These diagrams are essential because they allow a vet to spot a displaced tooth before it begins wearing down the opposite tooth or slicing into the dog’s own gum line or palate. If the occlusion is off, a tooth that is “correctly counted” can still be a medical liability.

How Many Teeth Do A Maltese Dog Have Compared To Other Breeds

To put it simply: a Maltese dog has the exact same number of teeth as a Golden Retriever or a German Shepherd—42 permanent teeth. The difference is not in the quantity, but in the density.

Imagine trying to fit 42 large pebbles into a small tea cup versus a large mixing bowl. The pebbles (the teeth) are the same size relative to the breed’s proportions, but in the “tea cup” (the Maltese jaw), they are pressed tightly against one another. This is the core of the small-breed dental struggle. In medium and large breeds, there is often more “interproximal space”—the gap between the teeth. This space allows saliva to wash away debris more effectively and makes it easier for owners to floss or brush.

Breeding has preserved the standard canine dental formula to ensure that the Maltese remains a functional predator/scavenger in terms of biology. However, this preservation has created an evolutionary mismatch. The skull shrunk over centuries of selective breeding for the “toy” aesthetic, but the dental formula stayed the same. Consequently, a Maltese is essentially a large-dog mouth compressed into a tiny face, which is why they require a level of dental maintenance that a larger breed simply doesn’t need to survive.

How Many Teeth Do Dogs Have In General

Across the board, dogs transition through two distinct sets of teeth: the deciduous (puppy) set and the permanent (adult) set. This biological transition is designed to ensure the puppy can eat solid food while its jaw is still growing.

The Deciduous Formula (Puppy): 28 Teeth
Puppies are born toothless. Their baby teeth begin to erupt around 3 to 4 weeks. This set consists of 12 incisors, 4 canines, and 12 premolars. Notably, puppies have no molars. Molars are the largest teeth and require a more developed jawbone to support their deep roots, which is why they only appear in the adult set.

The Permanent Formula (Adult): 42 Teeth
As the puppy matures, the 28 baby teeth are replaced by a more robust set. The adult formula adds the 10 molars and increases the number of premolars.

Canines44Tearing, HoldingGumline (Plaque traps)
Premolars1216Shearing, SlicingUpper 4th premolar (Heavy tartar)
Molars010Crushing, GrindingVery back (Hard to reach/brush)

A common myth is that “teacup” dogs or “micro” Maltese have fewer teeth. This is false. Even the smallest Maltese is biologically programmed for 42 teeth. If a “teacup” dog has fewer, it is usually due to hypodontia (congenital missing teeth) or, more commonly, premature tooth loss due to severe periodontal disease.

How Many Teeth Do Dogs Have And Can They Lose Them Naturally

The transition from 28 to 42 teeth is a natural, biological process. Between 3.5 and 6 months of age, the permanent teeth push upward, triggering a process called root resorption. The body essentially dissolves the root of the baby tooth, causing it to loosen and fall out. This is the only time a dog should “naturally” lose teeth.

Once a dog reaches adulthood, permanent teeth are not meant to fall out. If an adult Maltese loses a tooth, it is a medical emergency or a sign of chronic neglect. The most common cause is periodontal disease, which acts like a slow-motion demolition of the tooth’s foundation.

Plaque is a biofilm of bacteria that forms within hours of brushing. If not removed, it mineralizes into calculus (tartar) within 48 to 72 hours. In Maltese dogs, this tartar builds up rapidly on the upper premolars. The tartar pushes the gum line away from the tooth, creating a “periodontal pocket.” Bacteria then migrate deeper, eating away at the periodontal ligament and the alveolar bone. Eventually, the tooth loses its anchor and falls out—often accompanied by a systemic infection that can travel to the heart or kidneys.

Warning Signs of Abnormal Tooth Loss:

  • Halitosis: “Dog breath” that smells like rotting garbage or fish.
  • Gingivitis: A bright red line along the gum margin.
  • Pawing at the mouth: A sign of acute dental pain.
  • Slab Fractures: Chunks of the tooth missing due to chewing hard objects.

How Many Teeth Do Dogs Have For Cleaning And Common Issues

Because the Maltese has 42 teeth crowded into a tiny space, “cleaning” is not just about the surface; it is about the gaps. Plaque and tartar accumulate most aggressively on the maxillary (upper) fourth premolars. If you lift your Maltese’s lip, you will likely see a thick, brown-to-orange crust on those upper back teeth. This happens because the cheek pouches press the plaque against the teeth, and the salivary glands in the upper jaw provide a mineral-rich environment that accelerates tartar formation.

Daily preventive care is the only way to stop this. Brushing doesn’t just “clean” the tooth; it disrupts the biofilm. If you only brush once a week, the tartar that formed on Monday has already mineralized by Wednesday, and your brush will simply glide over the top of it without removing it.

Table 2: Safe vs. Dangerous Chew Materials for Maltese Teeth

MaterialSafety LevelEffect on TeethRecommendation
Soft Rubber (KONG)✅ SafeMassages gums, removes surface plaqueBest for daily use
Dental Chews (VOHC Approved)✅ SafeChemically and mechanically reduces tartarGreat supplement
Rawhide (Processed)⚠️ CautionChoking risk; some are too hard for toy jawsUse only under supervision
Deer Antlers/Hooves❌ DangerousHigh risk of Slab Fractures (tooth cracking)Avoid Entirely
Ice Cubes/Rocks❌ DangerousCauses micro-fractures in enamelAvoid Entirely
Nylon Bones (Hard)⚠️ CautionCan wear down enamel if the dog is an aggressive chewerUse “Soft” versions only

Chewing habits are a double-edged sword. While “mechanical abrasion” (chewing) helps scrape plaque off, many Maltese owners make the mistake of giving their dogs “hard” chews to “clean their teeth.” In a toy breed, the force exerted on a hard antler can easily exceed the strength of the tooth enamel, leading to a vertical fracture that requires a full extraction and an expensive vet bill.

How Many Teeth Do Puppies Have During Early Development

Maltese puppies begin their dental journey with 28 deciduous teeth. These teeth are smaller, sharper, and have shallower roots than adult teeth. They erupt in a predictable window, though individual puppies may vary by a week or two.

The Maltese Dental Milestone Timeline

AgeDental MilestoneWhat the Owner SeesAction Required
3–4 WeeksFirst EruptionTiny, needle-sharp incisors appearStart introducing soft puppy food
6–8 WeeksFull Deciduous SetAll 28 baby teeth are presentFirst vet dental check; count teeth
3.5–4 MonthsThe “Switch” BeginsBaby incisors begin to loosen; adult teeth emergeProvide safe teething toys (frozen cloths)
4–5 MonthsThe Canine TransitionBaby “fangs” fall out; adult canines eruptMonitor for “Double Teeth” (Retained)
5–6 MonthsPremolar ReplacementBack teeth are replaced by larger adult versionsWeekly “Lip-Lift” inspections
6–7 MonthsFinalizationAll 42 permanent teeth should be in placeFinal Deadline for Baby Tooth Loss

Teething behaviors in Maltese puppies can be intense. Because their mouths are so small, the pressure of a permanent tooth pushing through the gum is more concentrated. This leads to excessive drooling, “mouthiness” (biting everything), and occasional spotting of blood on toys.

Enamel development is critical during this phase. If a puppy’s diet is deficient in calcium or phosphorus, or if the mother suffered from nutritional stress, the enamel may be “hypoplastic” (thin or pitted). This makes the adult teeth more susceptible to decay and sensitivity for the rest of the dog’s life.

How Many Canine Teeth Do Puppies Have Before Adult Eruption

Puppies have four baby canine teeth—two on top, two on the bottom. These are the “fangs” that cause the most trouble for your furniture and your ankles. In a healthy puppy, these baby canines serve as “placeholders,” maintaining the space in the jaw and guiding the adult canine into the correct position.

Normal positioning involves the baby canine pointing slightly outward. However, in Maltese puppies, we often see abnormal fang positioning. This happens when the baby canine is angled too far inward, causing it to strike the roof of the mouth (the hard palate). This creates a painful ulcer and, more importantly, blocks the adult tooth from erupting.

If a baby canine is misaligned, it acts like a roadblock. The adult tooth, which is much stronger, will try to push around the roadblock, often erupting in a “ectopic” position (the wrong place). This can result in a tooth that grows into the gum or pushes the other teeth out of alignment, leading to a lifelong struggle with plaque and gum disease.

How Do Dental Changes Occur As Your Puppy Grows

The process of losing baby teeth is a biological miracle called odontoclasia. As the adult tooth grows in the jaw, it releases enzymes that dissolve the root of the baby tooth above it. Once the root is gone, the baby tooth has nothing holding it in and falls out—often while the puppy is eating or sleeping.

In a perfect world, the baby tooth falls out just as the adult tooth emerges. In the Maltese world, this rarely happens. Instead, owners encounter the “Shark Tooth” Phenomenon. This is when the adult tooth erupts behind or beside the baby tooth, leaving two rows of teeth in the mouth.

Table 3: Normal Teething vs. Concerning Dental Signs

To monitor this, I recommend the “Weekly Lip-Lift.” Gently lift the upper lip of your puppy and run your finger along the gum line. You are feeling for “double teeth.” If you feel two hard bumps where there should be one, you have a retained deciduous tooth.

How Many Teeth Do Small Dogs Have Versus Larger Breeds

As established, the count is identical (42), but the spatial dynamics are vastly different. This is known as the “Toy Breed Paradox.” In a large breed, the eruption schedule is often faster and more “clean.” The jaw grows rapidly, providing ample room for the adult teeth to slide into place.

In the Maltese, the jaw growth slows down significantly earlier. This means the eruption schedule can feel “sluggish.” An adult tooth may start to emerge at 4 months, but because the jaw isn’t expanding fast enough, the tooth gets “stuck.”

When evaluating tooth size relative to jaw size, a vet looks for crowding. In a Maltese, you will often see the premolars overlapping like shingles on a roof. While this doesn’t change the count of 42, it creates “blind spots” for toothbrushing. You cannot physically fit a toothbrush bristle between two overlapping teeth, which is why Maltese dogs often have “perfect” front teeth but “rotten” back teeth.

Why Do Smaller Canines Often Retain More Baby Teeth Longer

Retained deciduous teeth (persistent baby teeth) occur in an estimated 60% of toy breeds. The primary reason is failed root resorption.

For a baby tooth to fall out, the adult tooth must be positioned directly beneath it to “eat away” the root. In a tiny Maltese jaw, the adult tooth often erupts at a slight angle because there is no room. Because the adult tooth is not hitting the baby tooth’s root directly, the root remains intact. The baby tooth stays “locked” in the jaw, and the adult tooth is forced to erupt in the only space available—usually behind the baby tooth.

The Danger of the “Wait and See” Approach:
Many owners believe that “they’ll just fall out eventually.” This is a dangerous myth. Once a puppy hits 7 months, the biological window for natural resorption closes. A baby tooth that is still there at 7 months is likely to stay there for life.

If left untreated, retained teeth cause:

  1. Severe Malocclusion: The adult teeth are pushed into crooked positions.
  2. Rapid Tartar Buildup: The “double tooth” creates a V-shaped gap that traps food and is impossible to clean.
  3. Gum Recession: The crowding puts undue pressure on the periodontal ligament, causing the gums to recede.

Here is the thing: a retained baby tooth is not just a cosmetic issue; it is a “plaque factory” that can lead to tooth loss in the adult teeth by the time the dog is five years old.

How Can You Safely Manage Retained Baby Teeth In Puppies

Managing retained teeth starts with a commitment to non-invasive monitoring. The goal is to encourage the baby tooth to loosen naturally without causing trauma to the jaw.

The Safe Home Inspection Method (Step-by-Step):

  1. The Calm-Down: Give your puppy a lick-mat or a small treat to keep them occupied.
  2. The Lip-Lift: Using your non-dominant hand, gently lift the upper lip.
  3. The Tactile Check: Use your index finger to gently “wiggle” each tooth. A baby tooth that is ready to fall out will have a noticeable “give” or wobble.
  4. The Visual Scan: Look for the “shark tooth” (two teeth in one spot).
  5. The Log: Mark a calendar. If a tooth is “double” today, check it again in 7 days. If it hasn’t moved in 14 days, it’s time to call the vet.

Encouraging Natural Loss:
While you cannot “force” a tooth out, you can provide a stimulating environment that encourages it. Use frozen washcloths (soak a clean cloth in water or low-sodium chicken broth and freeze it). The cold numbs the inflamed gums, and the rough texture of the fabric provides the necessary friction to help a loose baby tooth finally snap off.

When Should Veterinary Intervention Be Scheduled For Dental Procedures

Veterinary intervention is not a “failure” of the owner; it is a standard part of toy breed healthcare. You should schedule a professional dental consultation the moment your puppy hits 6.5 to 7 months if any baby teeth remain.

Use Case: The “7-Month Retained Canine”

  • Situation: “Bella,” a 7-month-old Maltese, has a perfectly healthy adult canine tooth, but her baby canine is still rock-solid right next to it.
  • The Challenge: The owner waited 3 months, hoping it would fall out. Now, the adult tooth is starting to tilt inward, and the gums around the baby tooth are becoming bright red.
  • The Guidance: According to this guide, the “natural window” has closed. The baby tooth is now acting as a roadblock.
  • The Action: A vet visit is scheduled. Under safe gas anesthesia, the vet performs a “simple extraction” of the baby canine.
  • The Result: With the roadblock removed, the adult canine naturally shifts into the correct position over the next 4 weeks. Bella avoids a lifetime of malocclusion and expensive periodontal surgery.

Modern Veterinary Dental Procedures:
Many owners fear anesthesia, but for a Maltese, it is the only safe way to perform dental work. Modern clinics use Isoflurane or Sevoflurane gas, which allows for a rapid “wake up” and precise control of depth.

The procedure typically involves:

  1. Pre-Anesthetic Bloodwork: Ensuring the liver and kidneys can process the anesthesia.
  2. Dental X-rays: This is critical. A tooth may look fine on the surface but have a “retained root tip” underground.
  3. Extraction: The baby tooth is removed using a specialized elevator and forceps.
  4. Scaling and Polishing: While the dog is under, the vet removes any early tartar.

Post-Treatment Care Checklist:

  •  Soft Food Only: Feed canned food or soaked kibble for 3–5 days to avoid irritating the extraction site.
  •  Pain Management: Administer prescribed NSAIDs (like Carprofen) exactly as directed. Never give human Tylenol or Ibuprofen.
  •  Water Only: No hard treats or chew toys for 7 days.
  •  Daily Inspection: Check the extraction site for excessive bleeding or a “hole” that doesn’t seem to be closing.

Do I Need a Vet Appointment Right Now? (Branching Quiz)

Answer the following questions to determine your next step.

Question 1: Is your Maltese puppy currently under 6 months old?

  • Yes  Go to Question 2.
  • No  Go to Question 3.

Question 2: Do you see “double teeth” (an adult tooth next to a baby tooth)?

  • Yes, but the baby tooth is wobbly  RESULT: HOME MONITORING. This is normal. Provide a frozen washcloth and check again in 7 days.
  • Yes, and the baby tooth is rock-solid  RESULT: SCHEDULE A VISIT. Book a non-emergency vet appointment for the next 2 weeks to ensure the adult tooth isn’t erupting ectopically.
  • No  RESULT: ALL CLEAR. Continue weekly lip-lifts.

Question 3: How old is the puppy exactly, and are baby teeth still present?

  • 6 to 7 months old  RESULT: SCHEDULE A VISIT. You are in the “Grey Zone.” It’s time for a professional count to see if extractions are needed.
  • Over 7 months old  RESULT: URGENT VISIT. The window for natural loss has closed. Schedule an extraction consultation this week to prevent malocclusion.

Question 4 (Symptom Check): Regardless of age, are you seeing any of the following: Bright red gums, foul breath, or refusal to eat?

  • Yes  RESULT: EMERGENCY VISIT. These are signs of a dental abscess or severe infection. Call your vet immediately.
  • No  Follow the results of Questions 1-3.

What Daily Cleaning Routines Best Protect Maltese Teeth

Once the 42 permanent teeth are in place, the battle against tartar begins. For a Maltese, brushing is not “optional”—it is a medical necessity.

An effective routine involves mechanical disruption (brushing) and chemical disruption (enzymes). The gold standard is brushing once a day, ideally in the evening. This removes the food particles and plaque that accumulated throughout the day, preventing them from mineralizing into tartar overnight.

Table 4: Dental Tool Effectiveness Comparison

Professional dental cleanings should occur every 12 to 18 months. These are not “cosmetic” cleanings; they are surgical procedures. A vet uses an ultrasonic scaler to remove tartar from below the gumline (subgingival scaling). This is the only way to treat early-stage periodontal disease. If you only clean the visible part of the tooth, you are ignoring the area where the actual bone loss occurs.

Which Toothbrushes And Toothpastes Are Safest For Tiny Mouths

When shopping for a Maltese, “standard” dog toothbrushes are often too large. Trying to jam a large brush into a Maltese mouth can trigger a gag reflex and make the dog associate brushing with fear.

The Ideal Brush:
Look for a “Tiny Head” or “Angled” brush. The head should be no wider than the Maltese’s molar. Soft or ultra-soft bristles are mandatory. Medium or hard bristles can actually scrub away the delicate gum tissue of a toy breed, leading to “toothbrush-induced” gum recession.

The Ideal Toothpaste:
You must use a dedicated Enzyme Dog Toothpaste. These pastes contain enzymes like glucose oxidase and lysozyme. These enzymes work by breaking down the polysaccharide matrix of the plaque biofilm, essentially “digesting” the bacteria even in areas where the brush doesn’t perfectly reach.

⚠️ CRITICAL SAFETY WARNING: THE XYLITOL DANGER ⚠️
NEVER use human toothpaste on a dog.

  1. Fluoride: While not immediately lethal in tiny amounts, fluoride is toxic to dogs if swallowed, causing gastrointestinal irritation and potential kidney stress.
  2. Xylitol (The Killer): Many “sugar-free” or “whitening” human toothpastes contain Xylitol (a birch sugar). Xylitol is extremely toxic to dogs. It causes a massive insulin release, leading to a life-threatening drop in blood glucose (hypoglycemia) and acute liver failure. A single tube of Xylitol-containing toothpaste can be fatal for a 5-pound Maltese.

Proper Brushing Technique for Small Breeds:

  1. The “Tasting” Phase: Let your dog lick the toothpaste off your finger for 3 days to build a positive association.
  2. The Lip-Lift: Gently lift the upper lip.
  3. The 45-Degree Angle: Place the brush at a 45-degree angle toward the gumline. Do not brush “flat” against the tooth; you want the bristles to slightly enter the sulcus (the gap between tooth and gum).
  4. The Circular Motion: Use small, gentle circular motions.
  5. The “Back-to-Front” Approach: Start with the back molars (the hardest part) and end with the front incisors (the easiest part) so the dog ends the session on a “win.”

Frequently Asked Questions About How Many Teeth Do Maltese Dogs Have

How Many Teeth Do Maltese Dogs Have?

Adult Maltese dogs have exactly 42 permanent teeth, and Maltese puppies have 28 deciduous baby teeth. This count is a biological standard for all dogs, regardless of size. However, the Maltese is prone to “retained” baby teeth because their small jaw often lacks the space for adult teeth to push the baby teeth out naturally.

What Daily Cleaning Routines Best Protect Maltese Teeth From Tartar?

The most effective routine is daily brushing with a soft-bristled, tiny-head toothbrush and an enzyme-based dog toothpaste. This physically disrupts plaque before it can mineralize into tartar. To complement this, provide VOHC-approved dental chews and schedule a professional veterinary scaling and polishing every 12 to 18 months to remove subgingival tartar.
