If your filling or crown falls out, it’s crucial to act promptly. First, if you can find the filling or crown, clean it thoroughly and keep it safe. You might be able to temporarily reattach it with over-the-counter dental cement, but this is not a permanent solution. Avoid eating hard or sticky foods and try not to chew on the side of your mouth where the filling or crown was.
Make an appointment with your dentist as soon as possible. Depending on the situation, your dentist might be able to reattach the original filling or crown, or you might need a new one. If the tooth underneath is damaged, you might need additional treatment.
