tooth decay:
If your family has a history of tooth disease or teeth problems, then you may inherit it that way but good oral hygiene can save you from it.
This is very common, as many people inherit tooth problems that have been passed down from generation to generation but by taking good care of their teeth from childhood itself, they overcome any such problems!
2. Adults who suffer from a dry mouth are more at risk for cavities, as they have a lack of saliva in their mouth. Dry mouth is a very common disorder that can be caused by hormonal imbalance, mouth disease, or even as a side effect of some medications, illness, and radiation treatment. Tobacco users will also suffer from dry mouth, as the tobacco will use up the saliva in the mouth and leave the user with nothing to keep his or her mouth moist. This causes them to develop cavities and tooth decay.
