Possible problems: You were playing football without a mouth guard, or chewing, or maybe you don’t know how it happened, but now you’ve got a cracked molar. What to do: If the crack is just on the surface, a filling may do the trick. But if the tooth is sensitive to hot and cold, the problem is more complex but not impossible to fix. Try to chew on the other side and please book an appointment to see a dentist
