What are dental cavities?
Dental cavities, also called caries, are holes in teeth caused by bacteria. The bacteria mix with carbohydrates from foods and create acids. The acids break down areas of enamel, which covers the outside of a tooth.

What are symptoms of dental cavities?
You may not have any symptoms if cavities have just started to form. When cavities reach deeper parts of your tooth, you may start to feel pain. You may also have any of the following:
- Pain when you chew or eat hot or cold foods
- Chalky white, yellow, or brown tooth
- Gum swelling
How are dental cavities diagnosed?
Your dentist will look at your teeth to check for signs of enamel breakdown and cavities. He or she may also use x-rays to find cavities.
How are dental cavities treated?
- A fluoride treatment may be given during dental visits, or you may use products with fluoride at home. Your dentist will tell you what kind of fluoride you need and how to use it.
- A filling may be placed in your tooth after the decayed portion is removed. The filling may help to protect your tooth from more decay.
- A root canal may be needed if the tooth is infected or the decay is severe.
