Yellow Teeth in Dogs: Causes, Solutions, and the Importance of Canine Dental Health


As a pet owner, you likely want your furry friend to have healthy teeth and a bright smile.

However, you may have noticed that your dog’s teeth have a yellow tinge to them, and this can be concerning.

In this blog post, we’ll explore the reasons why your dog’s teeth are yellow and what you can do about it.

Why your dog’s teeth are yellow?

1. Plaque and Tartar Buildup

One of the most common reasons why a dog’s teeth may become yellow is the buildup of plaque and tartar.

Plaque is a sticky film that forms on teeth and contains bacteria. When plaque is not removed, it can harden and become tartar.

Tartar is a hard, yellow or brown substance that forms on teeth and can be difficult to remove.

Plaque and tartar buildup can lead to a variety of dental problems, including bad breath, gum disease, and tooth decay.

If left untreated, these conditions can lead to pain, infection, and tooth loss. Regular dental cleanings and at-home dental care can help prevent plaque and tartar buildup.

2. Diet

Another reason why a dog’s teeth may become yellow is their diet.

Just like humans, dogs can develop yellow teeth due to the foods they eat.

Foods that are high in sugar and carbohydrates can lead to tooth decay and discoloration.

Additionally, foods that are high in pigments, such as berries or beets, can also cause staining.

If you’re concerned about your dog’s diet and its effect on their teeth, it’s important to speak with your veterinarian.

They can provide guidance on what types of food are best for your dog’s dental health.

3. Genetics

Just like with humans, genetics can play a role in a dog’s dental health.

Some dogs may be more prone to developing yellow teeth due to their genetics.

Breeds that are known to have dental problems include Greyhounds, Chihuahuas, and Yorkshire Terriers.

If your dog is prone to dental problems due to their genetics, it’s important to provide regular dental care to prevent or address any issues that may arise.

4. Age

As dogs age, their teeth may become yellow. This is because the outer layer of the tooth, called the enamel, naturally wears away over time.

As the enamel wears away, the yellow dentin underneath becomes more visible.

While age-related yellowing is natural, it’s important to maintain good dental hygiene throughout your dog’s life to prevent other dental problems.

What Can You Do About Your Dog’s Yellow Teeth?

If you’ve noticed that your dog’s teeth are yellow, there are a few things you can do to help improve their dental health.

1. Dental Cleanings

Regular dental cleanings are an important part of your dog’s dental care routine.

A professional cleaning from a veterinarian can help remove any built-up plaque and tartar that may be causing yellowing.

Your veterinarian may also perform a dental exam to check for any other dental problems.

2. At-Home Dental Care

In addition to regular cleanings, at-home dental care can also help prevent yellowing and other dental problems.

This can include brushing your dog’s teeth regularly, providing dental chews or toys, and using dental rinses.

It’s important to note that not all dogs will tolerate tooth brushing or other forms of at-home dental care.

Your veterinarian can provide guidance on what types of dental care are best for your dog.

3. Diet Changes

If your dog’s diet is contributing to their yellowing teeth, making changes to their diet can help.

Speak with your veterinarian about what types of food are best for your dog’s dental health.


Yellowing teeth in dogs can be caused by a variety of factors, including plaque and tartar buildup, diet, genetics, and age.

Regular dental cleanings, at-home dental care, and dietary changes can all help improve your dog’s dental health and prevent yellowing and other dental problems.

If you’re concerned about your dog’s dental health, be sure to speak with your veterinarian for guidance on the best ways to care for your furry friend’s teeth.

With proper dental care, you can help ensure that your dog has a healthy smile for years to come.
