It could be reinfected. See a dentist.
If a root canal has been done properly, the tooth itself will never feel pain again. The root canal process removes all nerve tissue from the inside of the tooth. However, there will still be nerves surrounding the tooth located in the periodontal ligament that attaches the tooth to the bone. These nerves feel pressure, and help you 'feel' your teeth when you bite down. After a root canal is done, you can still 'feel' pressure-type pain from these outside nerves if you bite on something too hard or break your tooth.
If a tooth has a root canal filling you will not be able to know because the main factors of a tooth that has gone bad is sensitive to hot and cold or tender when putting any pressure on the tooth but if it has a root canal it is slightly different because the nerve is removed so you cant feel it. The tooth if it has a root canal will always go dark as the tooth is dead but this does not mean it is bad. The main sign of a bad tooth that has had root canal is an abscess under the tooth so if you feel pain when lying down that is keeping you awake at night or when leaning forward it really hurts then you have an abscess and that tooth will most probably have to be re-root canalled by a specialist or extracted! :)
No . . . the root canal procedure is intended to save the tooth.
that is a root canal of a molar tooth. Meaning the dentist is removing the nerve and pulp of the tooth.
If your tooth needs a root canal and is not painful, then it must be a dead tooth. When a tooth is dead, it is a source of infection which is not good. It is possible that it could hurt in the future due to infection. Better to have the root canal done, because you're trying to save your tooth. If you don't have the root canal treatment done and your tooth continues to decay, the dentist might have to pull that tooth out in the future. Once you pull out your tooth, that's gone forever
Is replacing bonded tooth with a crown necessary to prevent root canal?
