Root canal (or how to save a tooth)

Root canal is the extraction of the dead, damaged or sick tooth’s nerve; then, dental fillings seal cavities with a sealing material. If the tooth is very damaged and can cause a complete destruction of the dental piece this means a rebuild is necessary, too.

Nerve damages are commonly caused by fractures, deep cavities, severe mouth blows and bone or tooth root diseases. Discomfort commonly appears along with sensitivity to cold and heat, also the tooth becomes darker and there is some pain in chewing. Furthermore, there is a possible infection caused by dental bacteria.

If you think you need a root canal you should make an appointment with a dentist and explain the kind of pain you are experiencing. Secondly, the specialist should do an oral examination. A complete examination should include x-rays.

Root canal procedure requires applying anesthesia in the surgery area, mostly into the pulp chamber, which is the tooth nerve. Finally, the dentist removes cavities or dead parts of the nerve.

Lastly, if you feel dental discomfort like above mentioned, make an appointment as soon as you can for an earlier diagnosis for a root canal. This is the only way to make sure you will keep all of your dental pieces.
