Kids who have a ton of sugar make up only a small percentage
Cavities in adults are also quite common, which makes parents passing those germs onto their children even more plausible. Actually, approximately only 25% of the cavities occur in just children. Bacteria plays an important role in decay. In fact, this is why kids who eat a ton of candy or never floss are less likely to have any dental issues than kids with parents who also had a lot of cavities.
