Is root canal treatment appropriate for sensitive teeth?

Q. I had a filling in october 2007. My tooth has always been very sensitive to cold and hot stuff since the filling. The tooth is however not painful except recently when I try to bite on it. Secondly, if a put a sweet or anything sweet on the surface of the filling its very very painful.My dentist recently recommended a root canal treatmet. Do you think it would be the appropriate treatment considering the tooth is not painful but just sensitive to hot/cold and to feeling like when a spoon touches it.The tooth in question is the first molar.What could be the problem

A. Symptoms like these suggest that the nerve inside the tooth is alive but over sensitive. This is often due to the filling not being able to seal the tooth adequately, it is not necessarily a poor filling. Repeating the filling is an option that the dentist has not recommended, I assume they have assessed replacing the filling as being unlikely to produce a better result. Without Root canal the nerve will usually die and eventually cause an abscess.

Sensitivity to cold water after 1 week from the following treatment:
Bonded Amalgam Restoration on lower right Molar
Posterior Composite Filling on Upper Right Molar
This was because routine check up x-ray showed slight decay on both Molars
I have never had this problem in the past why now? Didn’t have pain before treatment. Has he actually damaged my teeth and I need root treatment. The bite is ok already checked that. He has caused untold amount of pain and misery why is this happening?

Hi, I am 63 years old and suffer from sensitive teeth I guess through brushing too hard. I would like to know if there is a cure other than using sensitive toothpaste (which I do use which is not really a cure only partly helps the problem) other than tooth extraction, what would be the procedure if any and approximate cost. I currently use a Oral B electric toothbrush. Thanks in anticipation.

Hi there, I have regular trouble with my teeth: very sensitive, swelling, trapped food, etc; and I want to try and get to the root of the problem (nopun intended!). I’m wondering if I can come in and get a quote? I have recently had NHS treatment (early Jan), and I still feel there is something not quite right. You website is excellent and shows some amazing case studies! I’m not looking for a razzle-dazzle smile, but just a set of teeth thatare pain free :). Please can someone get in touch? Kind regards
