Pain after root canal

Stupidly I was an overzealous brusher and gums receded a little on top two front teeth. Dentist put some bonding between gum and top tooth to stop food from getting stuck. My other front tooth dentist said was dead after X-ray. I had NO PAIN ever and there was no decay. Dentist suggested root canal. Now three months later I still have a strange feeling in that front tooth which I never had before. I also stings when I tap on it. What could be the cause? It was xrayed several times at time of root canal to make sure he got all the nerves. Tooth just doesn't feel the same. Surgeon said I do not need a cap in front tooth.

Answer: Pain after root canal

By Sarah h
Dental Professional

When there is trauma to a tooth and the nerve slowly dies over time,  the patient may not experience symptoms.   Therefore, the patient is unaware that the tooth is dead.  It is however evident on dental xrays with a periapical radiolucency.  After the dead nerve tissue is removed from a tooth and the canal is filled, the tooth will not feel the same as other vital teeth within the mouth.  It should not hurt or sting however, unless perhaps the tooth is over filled or fractured.  Percussion should feel different because the tooth is no longer vital, but a stinging sensation should subside once the tooth has healed from the root canal.  Give the tooth a few weeks time to heal, if there is no change or symptoms heighten, do not hesitate to call your dentist and have them take an xray to be sure that it is continuing to heal.
