Brushing Your Cat’s Teeth

Why should I brush my cat’s teeth?

More than half of all cats over the age of three have periodontal disease (infection of the tissues surrounding the teeth). Periodontal disease starts as gingivitis, resulting from plaque coming into contact with the gingiva (gums). If not removed through regular brushing, plaque thickens and mineralizes resulting in tartar. Left untreated, gingivitis may progress to destructive periodontal disease which may be painful and ultimately lead to tooth loss. See the handout “Dental Disease in Cats” for more information on periodontal disease.


When should I brush my cat's teeth?

Like us, cats need daily dental care to help decrease plaque and prevent tartar accumulation. Teaching your cat to accept the brushing of their teeth will take some training, but it will be relatively easy once they become accustomed to the process. Daily brushing is most beneficial and will help to establish a routine. Brushing a minimum of 3 times a week is helpful if your schedule cannot accommodate daily brushing.

"It is best to teach your cat to accept brushing while she is still a kitten."

It is best to teach your cat to accept brushing while she is still a kitten. If you have an older cat, the process may take a little longer, but it is still worth the effort.


What steps do I need to follow to teach my cat to accept tooth brushing?

In order to be successful brushing your cat’s teeth, it is important to make it a positive experience for both of you. For the best results, follow these steps:

  • Choose a quiet time and place to begin. Select a small room where you can place your cat on a surface such as a counter or tabletop (on a blanket or towel) or sit with her in your lap. Ensure the location is one where you can close the door to seal off escape avenues.
  • Dip a cotton swab (Q-tip) into tuna water drained from a can of tuna fish. The tuna water does not have any beneficial dental or cleaning effects, but most cats like the taste of it which will provide a positive connection between the tuna juice and the tooth brushing experience.
  • Place your cat’s head at a 45-degree angle and gently pull back her lips, the mouth can remain closed.
  • Gently rub the applicator tip along the area where the gum tissue touches the tooth surface (the gingival margin). This is the region where plaque accumulates and gingivitis is initiated. Only the outside surfaces of the teeth need to be rubbed.
  • For the first few lessons, it is a good idea to rub the cotton swab along only a few teeth rather than the whole mouth, especially if your cat is unsure or nervous about the process.
  • Once your cat is completely used to you rubbing her teeth with a cotton swab, it’s time to start using a toothbrush (see below).


What type of toothbrush should I use?

Commercial toothbrushes are available that are specifically designed for use in cats. These include:

  • brushes with angled handles,
  • small brushes that fit comfortably in your hand, and
  • finger toothbrushes (designed to fit over the tip of your finger).

For some cats, it is acceptable to use a very soft toothbrush designed for use in human babies. The toothbrush should be very soft. You can also use a finger toothbrush, gauze wrapped around a finger, or continue using a cotton swab.

Check with your veterinarian if you are uncertain of which brush to use. Ultimately, it is preferable to use a brush where the bristles can reach just below the gumline at the tooth/gum interface.

Regardless of the type of toothbrush you use, it is important to be gentle and go slowly as it is easy to accidentally poke the tip of the toothbrush against the gums and cause some irritation.


Is it okay to use human toothpaste?

No. Human toothpastes contain ingredients that should not be swallowed. If it is swallowed, it can cause an upset stomach or digestive disturbances. Some human toothpastes contain high levels of sodium which may even make your pet ill.


My friend recommended that I use baking soda. Is this okay?

No. Baking soda has a high alkaline content and, if swallowed, it can upset the acid balance in the stomach and digestive tract. In addition, baking soda does not taste good which may cause your cat to be uncooperative when you try to brush her teeth.


Why is pet toothpaste recommended?

Pet toothpaste is available in a number of different flavors that are appetizing to cats. By using a product that tastes good, your cat will be more likely to enjoy the whole experience.


Exactly how should I brush my cat’s teeth?

Following the procedure described above to get your cat used to have her teeth brushed follow these steps for a successful teeth brushing session.

  • Apply a small amount of toothpaste to the toothbrush. Place your cat’s head at a 45-degree angle and gently pull back her lips, the mouth can remain closed.
  • At first, concentrate on brushing the large cheek teeth and the canine teeth, the teeth where plaque and tartar accumulate most quickly. 
  • Do not worry about brushing the tips or insides of the teeth unless your cat is very cooperative. Most periodontal damage occurs on the outer surfaces of the teeth and around the roots and this is where you should direct your efforts. The cat's abrasive tongue tends to remove plaque from the inner surfaces of the teeth, reducing the need for brushing these surfaces.
  • Gradually work up to brushing all of the teeth (this will probably take several days or weeks). Make sure you reach the big teeth at the back of the mouth.


How much time should I spend brushing my cat's teeth?

Try to brush for approximately 30 seconds per side.


Is there anything else I should know?

Yes. A cat’s mouth contains lots of bacteria, if possible, wear gloves while brushing your cat’s teeth. If this limits your ability to effectively brush her teeth, then be sure to thoroughly wash your hands with soap and water after you are finished. Also, rinse the toothbrush thoroughly before putting it away. Replace the toothbrush every three months, and if you have several cats, use a different toothbrush for each one.
