An Explanation of Dental Caries
Why do I have so many cavities，Doctor?
It seems that every time I go to the dentist，there are at least three or four new ones.
Many of my fillings have been replaced two or three times.
Your teeth are very susceptible to decay.
The reasons for increased caries susceptibility in certain patients aren't fully understood by dental scientists.
There are many complicated factors involved in the formation of dental caries.
Can you give me an example，Doctor?
Heredity，prenatal development and diet are some of the factors that are important.
The body chemistry of an individual and particularly of the mouth and saliva are also important.
What is the most important?
The most important and practical thing for you to know about tooth decay is that it's caused by bacteria.
You can control the oral bacteria with daily home care.
If you remove the bacteria from your teeth by effective toothbrushing and dental flossing, you'll reduce the number of new cavities.
Is it possible to stop having new cavities?
Yes, you may be able to stop having new cavities.
The bacteria on the teeth use starches and sugars in the foods that you eat to form an acid that dissolves enamel.
