If you have one or more missing teeth, these can be replaced through having dental implant surgery. Artificial tooth roots are placed into your jaw, and can support crowns, bridges or dentures. Implant dentistry does involve several stages, but the end result should be teeth that look and feel as natural as possible. There are several types of dental implants that can be used depending on the amount of healthy bone in your jaw. If you do not have sufficient bone, mini dental implants might be suitable, or you may need a bone graft prior to implant surgery.
