Damaged nerve tissues and tooth pulp give rise to bacteria. If untreated, the bacteria spread through the roots of the tooth to other tissues and surrounding teeth and could cause abscesses. Infections that go undiagnosed due to an untreated root canal can also cause swelling on the face and neck. You might need a root canal treatment if:

The root cause of your tooth pain is severe decay caused by an untreated cavity.

You experience a severe toothache when chewing food.

There is prolonged pain in your teeth when exposed to heat/cold long after the source has been removed.

You have darkened or discolored teeth.

Your gums are swollen and tender.

You suffer from gum disease.

The dentin is exposed.

Remember, not every symptom indicates that you need to undergo a root canal procedure. While the above-mentioned signs may be an indication for a root canal treatment, it is always recommended to be concerned and seek expert assistance.
