Ladies, I'm facing this for the first time. My child is turning 7 this month, and I noticed a tiny crack on their 5th molar. A piece of popcorn husk got stuck in it. At first, I thought it was a cavity, but it turned out to be the husk. The fact that food gets stuck there and it could get worse means we need to see a dentist. What do they usually do in these cases? On the phone, they mentioned sealant as an option if there's no cavity yet.
