Is genetic influence significant in cavities?

I have a friend who is truly dedicated to dental care.

But that friend is always undergoing treatment.

So I don't know if it's because I am always busy taking care of my teeth.

Cavities occur when bacteria in dental plaque break down sugars from foods high in carbohydrates, producing acids that erode the teeth and lead to tooth decay.

When I see that friend, I don't like the party.

People with naturally weak enamel tend to have teeth that chip easily or develop cavities, even if they brush diligently.

Is it true that cavities are a disease heavily influenced by genetics?
