Generally, gum contouring is considered to be an extremely safe procedure. A local anaesthetic is used to keep you comfortable during the procedure. A minimal number of people may have an allergic reaction to the local anaesthetics being used. There is also always a chance of infection, especially if you do not follow aftercare instructions. While gum tissue relapse is also a possibility, it does not pose a health risk. As mentioned, with a proper diagnosis, we can avoid relapse.
