Hi Gum recession is due to so many causes Some of them are **Calculus formation that extends apically and cause gum recession **Faulty tooth brushing technique **Trauma from occlusion First you need to examine clinically to check for causes of gum recession based on that treatment plan has to be made.... Pinhole surgical technique is used for  marginal gum recession cases....it is a minor surgical technique and it will take one to two hours to complete the procedure.

Hello It’s very subjective We do the procedure We will need a picture of the concerned area As results are not very assured
