Whenever the nerve inside of the tooth pulp leads to irritations, becomes inflamed, it dies, people must consider root canal procedures. Some of the causes of nerve pulp infection or death might be due to traumas to the tooth via injuries, the enlargement of deep cavities in the tooth, large fixtures, old fillings, or persistent grinding of the teeth.
Oftentimes, an infected tooth shows signs and indicators including tenderness when biting, swelling, sensitivity to cold and hot stimulus, dull aching pain or sharp, shooting pain, and broad pain in the other places of the mouth, neck or head. Situations when the pain is almost nonexistent are very rare. Dental x-rays could be a useful tool if the bone tissue all-around the root of the tooth has been resorbed due to the infection.
An infected tooth or a dead tooth has just two therapy options, either a tooth extraction or root canal. If the infection goes untreated this might be very painful for the patient and might become dangerous if the infection spreads to the lungs, heart, or brain.
