Periodontal or gum surgery is performed to treat certain gum diseases and conditions, such as gingivitis or periodontitis which may have been caused by:

• regrowing damaged bones and tissues

• preventing tooth loss

• reducing gum gaps between teeth, known as black triangles

• reshaping the jaw hone to lower the risk for bacterial growth in bone crevices

• eliminating bacteria and infection

 

Pre-prosthetic surgery is the preparation of the mouth before the placement of a prosthesis. For example, a denture sits on the bone ridge, so it is very important that the bone is the proper shape and size. If a tooth needs to be extracted, the underlying bone might be left sharp and uneven. For the best fit of a denture, the bone might need to be smoothed out or reshaped. Occasionally, excess bone would need to be removed prior to denture insertion. This is done via a minor pre-prosthetic oral surgical procedure to ensure the maximum level of comfort
