Root canal sensitive to tapping

In more advanced cases, a sharp pain when biting down or lingering irritation after eating hot or cold foods can signal decay or damage to the pulp inside your tooth, which may require a root canal to clean it out. Re: does tapping on a tooth prove root canal is needed? If you have no response to endo ice and it hurts to percussion, the nerve is already dead and the infection has traveled through your tooth out the apex into your bone of your jaw- you also need a root canal.

A tooth has a double nerve supply (innervation) the internal in the pulp, and the external , supplying the surrounding tissue (periodontium). Root canal therapy cleans and removes tissue from the pulp space, so the tooth will not respond to hot or col but it will still feel pressure to bite or tap. The tooth is still sensitive when I tap it on the side , unlike other teeth.

Well, the tooth right next to it had a root canal over years ago and it feels the same when you tap on it. What I thought was an abcess my dentist and RDA friend are saying is just the bone under the gum. An endodontologist has special equipment and is trained to spot these missed canals. If this is the case they can do a new root canal treatment.

Another option is an infection on the root points but it seems unlikely that two dentists would have missed that on an x-ray. Sometimes a tooth may be sensitive to biting following a root canal. During a root canal the infected and damaged part of the tooth called the pulp is removed along with any infection at the end of the tooth root.

These areas may take several weeks to heal.

An infected root canal can usually be retreate unless the root is cracked or the tooth has broken below the gum line. In these cases, tooth extraction may be necessary. Cement or Air Forced Through the Root Tip.

It’s possible to overfill a root canal with dental cement, causing a bit of the material to ooze out of the root tip.

A root canal involves deep cleaning inside the canals (the inner chamber of the root) of your tooth, which can in turn irritate surrounding nerves and gums.

The pain shouldn’t last forever. It may be sensitive when you tap on it from the side even after the root canal is complete. Sometimes when the bone and ligament around your tooth heal, scar tissue may remain. A root canal is the removal of the inflame dying, dead or infected material found in the center of the tooth, the cleaning, shaping and tapering of the center of the root , and the sealing of the root to enable the bone and tissue around the root to heal.

I still feel pain when I touch that tooth or tap on it horizontally. Dentists when they tap on it top-down I have no pain. Any thoughts as to how and why would a tooth with a dead nerves still conduct pain. Pain gets worse as the day goes.

If pain is present on tapping after the root canal treatment it means the apical tissue of the tooth has not healed or there is a chance the root canal is not done properly and infwction is still there. Sometimes the root canal files we use to clean out the tooth roots go slightly past the end of the tooth and can either inject some bacteria at the tip of the root or temporarily damage the ligaments. This inflammation usually resolves by itself given enough time.

Another source of post root canal discomfort is a high bite and this can easily be corrected by your dentist. If you bite down, with no food in your mouth and the root canaled tooth hurts, then the bite should be adjusted.
