Are Cavities in Baby Teeth Common?

Many people think that some children or families are prone to cavities due to soft dental enamel. This is false. Cavities are actually caused by bacteria that feed on sugar residue left on teeth. This bacteria then secretes acid that settles on teeth, damages the enamel and results in cavities. It’s this bacteria that is passed from parent to child, especially through activities such as brushing with the same toothbrush or sharing utensils. So, cavities are more likely to occur in children whose parents also had lots of cavities in their youth.

This is why some children are seemingly able to eat tons of candy or fruit and never have any dental problems, even with poor brushing habits. Still, your child might need to have treatments or cavity fillings at a very young age due to having these specific types of oral bacteria in their mouths. It isn’t possible to treat the bacteria specifically, the best way to tackle them is to cut off its supply of sugar.
