The timing of gum grafting depends on the individual case and the severity of the gum recession. In general, it is best to undergo gum grafting as soon as possible after gum recession is detected because the longer you wait, the more likely it is that the recession will progress and the more difficult it may be to achieve optimal results.
That being said, there is no definitive age limit for gum grafting, and many older adults can still benefit from the procedure. However, factors such as overall health, the extent of the gum recession, and the presence of underlying health conditions may affect the feasibility and success of the procedure.
It is recommended to consult with a periodontist to determine whether gum grafting is a viable option for your specific case and to discuss the potential benefits and risks of the procedure.
