I have a tingling/numbness in my lower right lip following an attempted implant procedure. Will it regain its normal sensation?

2 years ago attempted implant in lower right gum,bone graft was required. Appears that there is now excess bone in my gum,I can feel the excess.Following the incision of the post I felt numbness in my lip.After about 6 months the post was removed, tingling remained. A bridge was installed instead of implant, hoping that the nerve would be restored. Tingling sometimes is more obvious than other times. Chewing also feels awkward at times, is this a result of the presumed excess bone in my gum?
