A root canal is done to get you out of pain from a toothache. Toothache occurs when the nerve in the tooth dies off, usually as a result of decay, trauma, gum disease, extreme wear or even cracks present in the tooth structure from old amalgam fillings. A root canal involves removing this infected nerve from your tooth, cleaning out bacteria in the nerve that is causing you pain, and sealing it to prevent re-infection and recurrent toothache.
Once this matter is removed the cavity is filled with a permanent filling, and finally fitted with a crown. Your tooth has now been saved and you are now free from a toothache. If root canal work is avoided and the situation worsen, the infection will become more severe and eventually lead to an abscess (A collection of pus that causes a bacterial infection and can spread to surrounding tissue with ease) this can be very damaging to your overall health and wellbeing.
The treatment is necessary because:
- Chronic area of infection noted on radiograph accompanied with or without pain
- The nerve within the tooth has become infected and is irreversibly damaged
- Without treatment, there is a high risk of continued infection, swelling or severe pain
- Without treatment the long term prognosis of the tooth is very poor and the tooth may have to be extracted
- This tooth has been determined to be an important tooth for the purpose of proper oral function and aesthetics and needs RCT to gain retention for the crown
- The pain is lingering in nature lasting more than few minutes and often needs painkillers to reduce it.
The benefits of this treatment are:
- Removal of infection from the tooth and surrounding bone and gum
- Elimination of pain
- Prevention of the early loss of the tooth
- Full and proper function of the tooth
