If you plan to have your tooth extracted, you need to consider whether or not you plan for replacing that missing tooth with a dental implant.
If you lose the tooth, the socket will collapse resulting in a thin area of bone. If you plan to replace it with a dental implant you should consider having a barrier and are bone graft placed in that site. This will leave you with more bone for a better implant result.
Usually, a dental implant is placed about 4 months after the tooth is extracted.
