Some fillings take a full 24 hours to reach their maximum strength so avoid hard food for the first day.
It is normal for some fillings to be sensitive to hot and cold for 10 to 14 days. Some larger fillings may be sensitive for 6 to 8 weeks depending or your body’s ability to heal.
If your filling feels like it is too high meaning that it feels as if it is the only or first tooth to hit when you bite down, you will need a follow up appointment to adjust or polish the filling. If left alone the pain will continue and eventually worsen.
