I had a very small crack in a tooth on the side of my mouth. It was so minor that my dentist had a hard time finding it. However it was causing me pain when I ate small particulate like bacon bits. I asked for a root canal, since the last time I got a crown on a live tooth, it continued to be sensitive. I am sixty years old with very good, hard teeth that have relatively few repairs and this was a relatively strong tooth, except for the sensitivity. Can I get by without a crown?

Doctor's Assistant: Have you noticed any recent swelling? Do you have any tooth pain?

No, just had a successful root canal

Doctor's Assistant: Please give me a bit more information, so the dentist can help you best.

Obviously an automated response...you have everything now.

The purpose of the crown is to protect a tooth that has a large amount of filling in it. If most of the tooth structure still remains,it is not necessary to have the tooth crowned even if it is root canaled. Root canaled teeth are more brittle because they have no blood supply. If the filling is small,the tooth can still remain without needing a crown.

This tooth had no prior filling and was only compromised enough to do the root canal. Just for additional clarity, it is the fourth tooth back on the top, counting from the gap between the front teeth.

I am unsure as to why the root canal is necessary. What type of symptoms are you having?

Ask Your Own Dental Question

Do you have an X-ray of this tooth to upload? Your sensitivity may just be coming from your bite and this can be corrected with a minor bite adjustment. A root canal would not be necessary in that case.

The tooth was cracked....a minor crack. I asked for the root canal, since a previous crown over a live tooth continued to have sensitivity to hot, cold, etc. I did not want work done to a live tooth that could cause more work later.

Pain to hot and cold is normally indicative of a tooth that is in hyper occlusion. If you actually had a vertical fracture,a root canal would not save the tooth. First a proper diagnosis needs to be made. Before anything else is done,your bite should be carefully checked. Symptoms of teeth needing root canal therapy are pain to heat,pain to biting pressure,swelling mobility, and darkening at the root tip showing bone loss. If you do not have most of these symptoms,your sensitivity will continue even after the root canal is done.

I'm sorry, but the root canal has been done!!!My question was a "mechanical" question about a crown, based on the location of the tooth, the fact that there was no cavity, and the fact that very little tooth was removed. All the other decisions have been made.

If the filling is small,the crown is really not necessary.

Ask Your Own Dental Question

I would still have the bite checked to make sure that you are not hitting this tooth too hard.

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.
