Could this be a sign that i might need a root canal? within the past few weeks one of my bottom molars has developed real sensitivity to hot and cold. there isn't any constant pain, or any different sensations beyond that sensitivity. i've never experienc

Yes : Yes temperature sensitivity is often a sign that the nerve of a tooth is not healthy you should see an endodontist(specialist in rct) as soon as possible the endodontist will be able to determine if you do or do not need a rct a toothache can come on very fast and painful so you should look into this right away with today technology, rct is now a quick and painless procedure so try not to worry very much about the procedure without it, you could end up in severe pain and with a terrible infection which would be a much worse senerio.

Sensitivity : Sensitivity to hot and cold means that the nerve in your tooth is alive, and is responding to the thermal stimulus. It could be coming from a cracked filling which is leaking, a new cavity, or even sensitivity from the root surface if your gingival tissue has receeded. Your actual tooth may also be fractured. One thing is for sure: if it is a new cavity or a cracked filling, failure to treat it sooner than later will only result in increased sensitivity, more intense pain, and an almost certain need for root canal therapy. To avoid the later, make an appointment with your dentist to evaluate the cause of your sensitivity and have it treated if necessary.

Oviously : Oviously you are aware that something is not normal. However, it may not be a big deal. A small crack, cavity or missing filling can easily be repaired without root canal treatment. Delaying treatment will only make things worse later. Get to a dentist as soon as possible and find out why it's sensitive and maybe the fix is easier than you think!

Sensitivity : Sensitivity can also develop from periodontitis. Teeth have also porosity as our skin, in the presence of bacteria imbalance ( more than the usual) it creates an acid medium that sometimes decalcifies the enamel of the tooth creating an open channel to the pulp chamber(where the nerve resides) the treatment is the use of a medicated fluoridated cream or tooth paste, and if this will be the reasoning of your sensitivity you would have solved your problem. Anyways you need to visit your dentist in order to determine if you have a periodontal or endodontic condition. Good luck!
