Did you know Chihuahuas have the same number of teeth as Great Danes? They have 42 teeth: 20 on top and 22 on the bottom. This chihuahua teeth count is the same for all dog breeds, even though their mouths are much smaller.
Imagine fitting 42 teeth in a face as small as a human hand. This tight space often causes dental problems for these tiny dogs.
Adult Chihuahuas have 12 incisors, 4 canines, 16 premolars, and 10 molars. Their small size might make their teeth seem too close together. But, their chihuahua teeth count is the same as bigger breeds.

This guide will cover why their mouth anatomy is important. We’ll also talk about how to keep their 42 teeth healthy. Let’s dive into the surprising facts about their tiny, toothy smiles.
Understanding Chihuahua Dental Anatomy
Chihuahua dental anatomy is quite interesting and complex. These small dogs have 42 permanent teeth, just like bigger dogs. But, their tiny jaws make chihuahua oral health a big challenge. Owners must watch tooth alignment and spacing closely.
Unique Structure of Chihuahua Mouths
Chihuahuas’ mouths are tiny, with 42 teeth in a jaw only 10% as big as a Great Dane’s. This tight space raises the risk of plaque and tooth misalignment. Regular dental checks are key to prevent gum strain.
How Chihuahua Teeth Compare to Other Dog Breeds
All adult dogs have 42 teeth, but smaller breeds like Chihuahuas face more dental disease risks. Bigger breeds, like German Shepherds, have more space between their teeth. This means Chihuahuas’ teeth are smaller but packed tightly, stressing their oral health.
The Function of Different Tooth Types
- Incisors: 12 small front teeth for grooming and nibbling.
- Canines: Four pointed teeth for gripping, critical for biting force.
- Pre-molars: 16 teeth designed for shredding and grinding food.
- Molars: 10 flat-surfaced teeth crush hard foods, aiding digestion.
Each tooth type plays a specific role. Proper alignment in chihuahua dental anatomy is vital. Misalignment can make chewing hard and trap food, leading to tooth decay.
How Many Teeth Do Chihuahuas Have?
Adult Chihuahuas have 42 teeth in total. This is the same as all dog breeds. They have 20 teeth on the upper jaw and 22 on the lower jaw. Each type of tooth presents its own challenges, despite the standard count.

Type | Count | Function |
---|---|---|
Incisors | 12 | Cutting food and grooming |
Canines | 4 | Tearing and gripping |
Premolars | 16 | Crushing and grinding |
Molars | 10 | Finely grinding food |
These teeth fit into a jaw smaller than a human thumb. This leads to tight spacing. Unlike larger breeds, Chihuahuas often face overcrowding risks. Humans have just 32 permanent teeth, showing how compact their mouths are.
Chihuahua teeth count follows the same formula as bigger dogs, but size differences create unique care needs. Regular checks are vital to spot misalignment early. A study from the American Veterinary Dental College confirms small breeds like Chihuahuas have higher rates of dental issues due to these anatomical constraints.
Owners should note that 42 teeth aren’t the issue—space management is key. Brushing and vet visits prevent overcrowding complications. For a visual guide, explore this resource to see dental anatomy comparisons.
Chihuahua Puppy Teeth: The Deciduous Stage

Chihuahua puppy teeth start coming in at 3 weeks with tiny incisors. By 6 weeks, all 28 deciduous teeth are in. This is a key time for their chihuahua oral health to grow. Regular checks are important for owners to watch this stage.
When Puppies Start Teething
Puppies start teething between 2–3 weeks. By 6–8 weeks, they have all their baby teeth. At 12 weeks, their permanent teeth start coming in. Signs like drooling or chewing show they are teething.
The Number of Puppy Teeth
Chihuahua puppies have 28 deciduous teeth. They are split evenly between the upper and lower jaws. These include:
Tooth Type | Count | Function |
---|---|---|
Incisors | 12 | Nibbling and grooming |
Canines | 4 | Grasping and gripping |
Premolars | 12 | Chewing and crushing food |
Managing Teething Discomfort
Here are ways to ease teething pain:
- Offer rubber toys or puppy-safe chew items
- Clean gums gently with a soft cloth
- Monitor for retained teeth that don’t fall out naturally
Retained baby teeth can trap food, leading to decay. Take your puppy to the vet to check for any issues with their permanent teeth.
The Transition to Adult Teeth in Chihuahuas
Chihuahuas start to get their chihuahua adult teeth between 3.5 and 7 months old. By 7 months, they should have 42 permanent teeth. This is the usual chihuahua teeth count for adult dogs.
This change happens when puppy teeth start to loosen. Adult teeth then push through the gums.

Stage | Age Range | Key Event |
---|---|---|
Puppy Teeth Loss | 12–16 weeks | Baby teeth fall out to make space |
Adult Tooth Eruption | 4–7 months | 42 permanent teeth fully emerge |
Risk Period | 3–6 months | Potential retained puppy teeth complications |
Chihuahuas have small jaws, which can cause problems. A common issue is when baby teeth don’t fall out. This can lead to overcrowding and misalignment of the chihuahua adult teeth.
Symptoms include double rows of teeth or baby teeth next to new ones.
- By 6 months, all baby teeth should be gone
- Retained teeth affect chihuahua teeth count accuracy
- Overcrowding risks increase without vet intervention
Veterinary checks during this time are very important. X-rays might be needed to check if teeth are coming in right. If there are retained teeth, they often need to be removed.
Watching this transition closely helps ensure the chihuahua teeth count is correct. This helps avoid dental problems later on.
Common Dental Issues in Chihuahuas
Chihuahuas have special chihuahua dental issues because of their small mouths and genetics. They have 42 adult teeth, just like bigger dogs. But their tiny jaws struggle to fit these teeth, hurting their chihuahua oral health.
Overcrowding Problems
- Small jaws force teeth to crowd, trapping food and bacteria.
- Overcrowding raises plaque and tartar buildup risks, damaging enamel and gums.
Retained Deciduous Teeth
5.7% of Chihuahuas keep their baby teeth, making double rows. This stops adult teeth from fitting right, making overcrowding worse.
Periodontal Disease Risks
Overcrowding makes plaque turn into hard tartar, causing gum inflammation. Studies show 13.5% of Chihuahuas get periodontal disease. If not treated, it can spread to bones and organs.
Tooth Decay and Fractures
Thin jawbones make fractures likely during play. Enamel erosion from overcrowding lets decay spread fast.
Tooth Type | Count |
---|---|
Incisors | 12 |
Canines | 4 |
Premolars | 16 |
Molars | 10 |
Essential Dental Care for Your Chihuahua
Keeping your Chihuahua’s chihuahua dental care routine going is all about daily habits and getting help from pros. Good chihuahua oral health stops problems like tooth decay and gum disease. This keeps your pet healthy and happy.
Daily Brushing Techniques
Brush your Chihuahua’s teeth at least three times a week. Use dog toothpaste and a soft brush or finger tool. Begin by letting your Chihuahua sniff the brush. Then, brush the outer surfaces and gums gently. Give praise to make it a positive experience. Never use human toothpaste, as it’s harmful.
- Brush gently using circular motions
- Choose enzymatic dog toothpaste
- Acclimate gradually over 1–2 weeks
Dental Treats and Toys
Choose VOHC-approved dental products like Pet Honesty’s Dental Health Powder or Dental Health Sticks. These treats help reduce plaque and freshen breath. Also, use rubber toys that gently massage the gums. But, avoid hard chews that could harm teeth.
Professional Cleaning Importance
Annual vet cleanings are a must. Vets scale teeth and check for hidden problems during these visits. Anesthesia makes the cleaning thorough without stressing your pet. Remember, early care saves money in the long run. Talk to your vet about how to prepare your pet for the visit.
How Dental Health Affects Your Chihuahua’s Overall Wellbeing
Chihuahua oral health is more than just about their teeth. It’s a key to their overall health. Bad chihuahua dental issues can lead to serious problems. Bacteria from gum infections can reach vital organs, stressing the heart, kidneys, and liver.
A study found that 80% of dogs show early dental disease by age three. This puts Chihuahuas at high risk.
“Healthy teeth mean a healthier pet. Dental neglect can shorten a Chihuahua’s lifespan.” —Dr. Emily Carter, Veterinary Dentist
Chihuahuas have 42 teeth, just like bigger dogs. But their teeth are packed tightly, making it hard to clean. This leads to periodontal disease, which harms gums and bones.
The problems don’t stop at the mouth:
- Heart: Bacteria can damage heart valves, causing endocarditis.
- Liver/Kidneys: Chronic infections strain these organs, reducing their ability to filter toxins.
- Immune System: Persistent infections weaken defenses against other illnesses.
Behavioral changes can signal deeper issues. Chihuahuas with dental pain may:
- Refuse crunchy food, leading to malnutrition.
- Withdraw from play due to discomfort.
- Show irritability from constant pain.
With lifespans of 15-18 years, it’s important to act early. Daily brushing, vet cleanings, and watching for retained puppy teeth can prevent big problems. Ignoring chihuahua dental issues risks more than bad breath—it threatens their long-term health and happiness. Dental care is not optional; it’s essential for their well-being.
