In order to maintain good dental health, you must maintain a good, daily dental routine. This consists of brushing your teeth twice a day, flossing once a day, and visiting the dentist every six months for a professional dental cleaning.


There are many different parts of your mouth that determine your dental health. Here are 25 interesting dental facts about your mouth, from your teeth to your tongue.




The outer layer of your teeth, called enamel, is the hardest part of your entire body.


Tooth Decay

Sugar itself doesn’t cause tooth decay. The bacteria in your mouth feed on the sugars you consume and produce enamel-destroying acids that cause tooth decay.


Unique Teeth

No two people have the same set of teeth; they’re just as unique as fingerprints.

Your Teeth Exposed

One-third of your tooth is underneath your gums.


Teeth by the Numbers

Children have 20 baby teeth, while adults have 32 permanent teeth (if you don’t have any teeth removed).


Enamel Durability

Any damage to your enamel is permanent; enamel can’t be restored.


Color of Teeth

The color of your teeth isn’t determined by your enamel. The second layer of your teeth, called dentin, is responsible for the color of your teeth.


Baby Teeth

As a child’s permanent teeth grow, they put pressure on their baby teeth and cause the roots of the baby teeth to dissolve. As a child loses baby teeth, the permanent teeth grow into the open spaces.


Decreasing Decay

Only 40% of children ages 6 to 19 have had cavities, which is 10% less than 10 years ago.

Tooth Types

We have 4 types of teeth in our mouth – incisors, canines, molars, and pre-molars.



Tongue Print

Like fingerprints and teeth, your tongue print is unique.



On average, a person produces a quart of saliva every day.


Taste Buds

You have 4 main types of taste buds: sour, sweet, salty, and bitter. A relatively new taste, umami, is often added and is used to describe savory tastes.



Dental plaque is made up of more than 300 types of bacteria.



The plaque you don’t remove through brushing and flossing hardens to tartar, which can be removed only by the dentist or dental hygienist.



Your mouth is important for chewing, talking, and swallowing.



Kids laugh an average of 400 times each day. Adults laugh an average of only 15 times a day.

Flossing is Important

Replacing Toothbrushes

You should replace your toothbrush or toothbrush head every 3 to 4 months, or when the bristles begin to fray.


Floss Sales

An average of over 3 million miles of dental floss is purchased in North America each year.
