Unfortunately the tooth must go.

Tooth extraction is the last resort when nothing can be done to save the tooth. For example, a tooth destroyed by caries or injury, or when the loss of surrounding teeth renders a tooth unstable. Or  in cases of periodontitis or where root canal treatment is not possible. The wisdom teeth can cause problems sometimes, remaining enclosed in the gum resulting in painful inflammations damaging the neighbouring teeth.

such teeth must be extracted to avoid serious damage to the jawbone and nerves. Oral surgery preparation of the jawbone is also required for implant treatments. The implantation of artificial roots ( implants) in the jawbone allows for comfortable dentures even when the natural teeth do not exist or have been lost.
