Can tooth decay be genetic

While it is not true that if your parents have a lot of decay, you will also have a lot of decay, it is true that there is a genetic predisposition to tooth decay. This simply means that you may have to work harder to maintain good oral hygiene to prevent tooth decay.

Tooth decay is primarily a function of poor oral hygiene. Keep you mouth adequately clean, see your dentist and hygienist frequently, follow their advice, and you will likely experience less tooth decay.
