One of the biggest causes of numbness in the lower lip is extracting wisdom teeth. Well, I haven't had that done, so I'm stumped.
When I woke up 5 days ago, I realized part of my lower lip was numb? I couldn't imagine what the problem was. I figured it would go away with time. Well, it hasn't and it has seemed to cover more area of my lower lip. Please tell me what you think. I've researched causes for this, but have been unable to find anything. I went to the doctor yesterday and he couldn't figure out what the problem was. He said it could be because I drank heavily the night before and depleted myself of vitamin B. Does that sound logical? Someone please help.
