I had a mandibular wisdom tooth extraction several months ago. Actually several teeth were removed, and necessitated general anesthesia. The swelling is long gone, I am eating normal food now, but the tip of my tongue feels burnt, like I had just had very hot coffee. It's not terrible, but it is a low-grade pain that isn't going away. It's been well over eight weeks, but less than six months, and it's very annoying and unpleasant.
