Dental caries can damage your gums and, if not detected early, can lead to tooth extraction. Root canals are the best way to treat decaying teeth.

During root canal treatment, the infected pulp and nerves are removed and the dentist cleans and covers the inside of the affected tooth. Without this procedure, the surrounding tooth tissue becomes inflamed and an abscess develops.

All the teeth in your mouth contain nerves and blood vessels that are in the middle of the canals deep down the roots. When your teeth are first formed, these blood vessels and nerves provide all the essential nutrients they need. You can also consult with a root canal dentist via

However, you may or may not know whether you need treatment and, if so, when exactly you should receive it. Whenever you have a toothache, it's not a sure indicator that you need an extraction or root canal treatment. 

It all depends on the severity of the pain. If the pain becomes so excruciating that you can't eat or drink anything, you should see a dentist as soon as possible.

He will check whether there are cavities or not and whether the tooth is causing inflammation or infection of the blood vessels and nerves of the teeth. If your neck or face is swollen, that's a sign you need an RCT.

Drinking hot drinks like coffee and tea and eating cold foods like ice cream shouldn't be a problem. However, if you continue to feel sensitive after consuming these foods, it could be a sign of danger.
