When does a tooth need root canal treatment?
A tooth is currently causing you pain or else has a history of being painful.
You have noticed the presence of tenderness or swelling in your gums near a tooth.
There can be times when you have a tooth that does need root canal treatment but you are unaware of this fact because there has been no swelling or pain associated with the tooth:
Problem teeth identified by x-rays
The nerve tissue in a tooth can die quietly. The degeneration of tooth s nerve is not always a painful experience.
Because of this, on occasion, a tooth need for root canal treatment can remain undiscovered, even for some years. This is because in these instances the virulence of the infection in the tooth is low and your body s defense mechanism, while not being able to clear up the infection totally, is able to keep it in check.Điều trị tủy răng
A persistent or reoccurring pimple on your gums
Sometimes a tooth whose nerve has died will produce a pimple like lesion on a person s gums. The presence and/or size of these pimples (dentists call them fistulous tracts) can come and go. Because they are literally drains for pus from an infected tooth, a person might notice that they discharge a bad taste (the pus).
Exposure of a tooth s nerve
There can be times when your dentist will find that your needed dental work has resulted in the exposure of your tooth s nerve tissue. Sometimes you will feel a little prick of pain when the exposure occurs, however many times a patient is totally unaware of the event.
An exposure can lead to the degeneration of a tooth s nerve tissue. Your dentist may determine that in your situation it is best to go ahead and perform root canal treatment on the tooth now so to avoid possible problems and complications with the tooth.
Teeth which have been traumatized in an accident
The health of the nerve tissue in teeth which have a history of having been traumatized can deteriorate, thus leading to the need for root canal treatment.
Immediately after a traumatic event the outlook for the health of a tooth s nerve can be difficult to predict. Sometimes these teeth do quite well, even for many years. It is always possible however that at some point the health of the tooth s nerve tissue will go ahead and degenerate. A tip off that the nerve tissue inside a tooth is undergoing degenerative changes is that the tooth, in comparison to its neighbours, appears darkened.
