Before
Tell the dentist which tooth is bothering you and when you first noticed a change.
During
Ask how much of the tooth can be kept, which material is suitable and whether your care needs more than one visit.
After
Follow the care instructions you are given. Ask whom to contact if the tooth remains uncomfortable or the bite feels different.
