Is it normal for my tongue to feel numb?!

I went to the dentist because I had a loose filling. My dentist removed the decay and told me that he can't put a real filling in, only a temporary one because some decay got into the pulp and if it touches the nerve and bothers me I'll have to get a root canal.

I have never felt my tongue be numb...Nothing else is numb but my tongue and I'm hungry! not only that, its weird cuz I cant aste the nastiness of the filling ugh! Tastes like medicine. Is that normal too.? Health Question & Answer
