Small Dog Teeth Problems: Why Small Breeds Suffer Most

Small dogs often develop dental disease earlier than big dogs. Learn why, which breeds are most at risk, and how to protect your small dog's teeth.

Tiny dogs, big dental drama. If you can relate to that, you're in the right place. Sharing your life with a small dog, like a Chihuahua, Yorkie, or Pomeranian, means there's a good chance their teeth will need more attention than a much bigger dog. 

Small dog teeth problems tend to show up earlier and progress faster, and they're easy to miss under a cute little lip.

Here's what every small-dog parent should know...

Why Small Breeds Are More Prone to Dental Disease

According to the American Kennel Club, most small dogs have the same number of adult teeth as big dogs, just packed into a much smaller mouth. When you look at it that way, that's a lot of teeth in a tiny space. Let's break this down into a few key reasons...

1. Jaw crowding

When all those teeth share a tiny jaw, they often sit close together, overlap, or grow at odd angles. Those tight spaces trap food and plaque, and plaque that isn't removed hardens into tartar. Tartar along the gumline irritates the gums and can lead to periodontal disease over time.

2. Retained baby teeth

Toy breeds are known for holding onto puppy teeth after the adult teeth come in. Two teeth squeezed into one spot create even more crowding and more places for bacteria to hide.

3. Genetics and jaw shape

Some breeds are simply built this way. Flat-faced dogs like French Bulldogs have shortened jaws that crowd and rotate teeth, while fine-boned toy breeds usually have less jawbone supporting each tooth, so gum disease can affect them sooner. 

Signs of Dental Disease in Small Dogs

Dental disease usually starts quietly, so it pays to lift that little lip once a week and take a look. Common signs include:

• Bad breath that doesn't go away.
• Yellow or brown tartar along the gumline.
• Red, swollen, or bleeding gums.
• Loose, broken, or missing teeth.
• Chewing on one side or dropping food.
• Pawing at the mouth or rubbing the face on the floor.

Small dogs are experts at hiding discomfort, so even subtle changes in eating habits are worth a vet visit just to make sure you know what's going on.

Prevention for Small Dogs

There are a few methods to help keep your dog's teeth in a good way. These are the main ones:

1. Daily brushing for tiny mouths

Brushing is the gold standard, and small dogs need it most. Use a soft finger brush or a small-headed toothbrush made for dogs, plus a dog-safe toothpaste. Never use human toothpaste, which can contain ingredients that aren't safe for dogs. For more options on how to clean their teeth, see our guide to dog dental tools.

2. Dental chews sized for small breeds

Choose chews made for your dog's weight range. Chews that are too big are hard for tiny jaws to grip, while ones that are too small can be swallowed whole. Supervise chewing, and skip anything hard enough to crack a tooth, like antlers or bones.

3. Regular vet checks

Ask your vet to look at your dog's teeth at every annual visit, and follow their advice on professional cleanings.

How Nutrition and Supplements Support Oral Health

What your small dog eats plays a supporting role in oral health. A complete, balanced diet gives teeth and gums the nutrients they need, and some foods are designed with a texture that helps reduce plaque as your dog chews. Learn more in our guide to dental dog food.

Supplements can add an easy extra layer to your routine, especially for dogs who won't sit still for brushing. Wuffes Dental Powder is a simple sprinkle-on option you add to your dog's food, designed to support fresh breath and healthy teeth and gums between brushings. Since it mixes right into meals, there's no wrestling with a tiny mouth. 

FAQs

When should small dogs get their first dental clean?

The majority of vets suggest small dogs have their first professional dental cleaning somewhere between one and three years old, although the right timing depends on your dog's mouth, not just the calendar. Toy breeds often buildup tartar sooner than larger dogs because their teeth are crowded together.

Your vet will check your dog's teeth at routine visits and let you know when a cleaning is needed. Professional cleanings are done under anesthesia so the vet can safely clean below the gumline and carefully examine every tooth. Daily brushing and good home care can help stretch the time between cleanings. 

Are dental chews enough to keep my small dog's teeth clean?

Dental chews are a helpful part of a small dog's routine, but they aren't enough on their own. Chewing can help scrape away some plaque from the surfaces of the teeth, but it can't reach every tooth or clean below the gumline, where gum disease starts. Small breeds with crowded teeth have plenty of tight spots that even good chews miss.

For the best results, pair small-breed-sized dental chews with daily brushing, a dental supplement like Wuffes Dental Powder, and regular vet checkups. Always choose chews sized for your dog's weight range, and supervise them closely every time they chew.

How often should I brush my small dog's teeth?

Aim to brush your small dog's teeth every day. Plaque starts forming within hours of eating and can harden into tartar in just a few days, so daily brushing is the most effective way to keep it under control. If every day isn't realistic, brushing at least three times a week still makes a real difference.

Use a soft finger brush or small dog toothbrush and a dog-safe toothpaste, never human toothpaste. Keep sessions short and positive, focusing on the outer surfaces of the back teeth, where tartar tends to buildup first. Remember, consistency matters far more than perfection. 

How many teeth do small dogs have?

Adult small dogs have 42 teeth, the same as large breeds like Labradors. Puppies have 28 baby teeth, which usually fall out and are replaced by adult teeth by around six months of age. Because small dogs fit all 42 adult teeth into a much smaller jaw, their teeth are often crowded, overlapping, or rotated.

This crowding traps food and plaque, which is a big reason small breeds are more prone to dental disease. Some toy breeds may also be missing a few teeth naturally or keep baby teeth that never fall out, which a vet may need to remove. 

To Sum Up

Small dogs may have small mouths, but their teeth need big attention. Crowded jaws, stubborn baby teeth, and breed genetics all put small breeds at higher risk of dental disease.

The good news is that a simple routine goes a long way: brush daily, choose dental chews sized for your dog, add a supplement, and keep up with vet checkups.
