Q. Hello, I have had a root canal done to my second molar. My dentist has suggested that I best have a temporary crown fitted, as my tooth is very vulnerable. The reason for him to say this is because:- A) last week I had my tooth quarterly spilt, which he managed to extract and fill it up. B) this is what i dont understand, he says that the tooth above my second molar is sharp ( along those lines) and is not doing any favours to my second molar. C) if i decide to remove my tooth, there is a possiblity that my molar will eventually get loose and i might loose it. I havent had my wisdom tooth come out as yet. What’s a temporary filling? I personally find all this a hassle now, It’s so frustrating, can’t I just remove it!
