Questions to ask your dentist

  • The typical case takes one visit. Would mine, and how long would it take?
  • What are my other options, including waiting, and what happens if I wait?
  • How long does it usually last in a case like mine, and what upkeep will it need?
  • Will it hurt, and what can I eat or do while it heals?
  • What will it cost me, and will my insurance cover it? Ask which billing codes apply (the typical case uses D9972, D9975).
  • How many of these have you done, and who would do mine?
