What causes cavities?
Cavities are caused by bacteria that live in your mouth.
These bacteria feed off the sugar that remains in your mouth after you eat, producing acid. Bacteria, acid, and food residue clings to your teeth in the form of plaque. When the plaque is not removed on a regular basis by brushing and flossing, the acids will erode the surface of the tooth until a small part of the tooth collapses, creating a cavity.
If a cavity is left untreated, it will eventually develop into a larger decay problem.
You can avoid cavities by:
- Brushing and flossing regularly as directed by Dr. Liao
- Avoiding sugary snacks
- Drinking plenty of water
- Using a fluoride toothpaste
- Asking about preventive treatments that strengthen and protect your teeth, like fluoride treatments and sealants
