Dentist Questions tooth pain

Pain and bad taste in mouth. Why isn't it going away?

I had a root canal over a year ago, and then I had a cap placed on the tooth after the procedure. I've had intermittent pain near that tooth, especially when I'm chewing on something hard. Sometimes, I also have a bad taste in my mouth. Why hasn't this pain and bad taste gone away after my root canal?

It is possible that there is a problem with re-infection after the root canal was done. Another possibility is that the crown may be ever so slightly high and need an adjustment.
I would suggest that you see your dentist and ask them to evaluate the situation.
You have not provided enough information for me to determine why you still have intermittent pain in your tooth and also why there is a bad taste. You should return to the dentist who did your root canal, who can examine and xray the area to determine what is going on.
You need to get back to your dentist. Not all root canals work. You have to be careful. When patients say biting down on something hard, ice, hard nuts, hardtack candy, a root canal tooth gets brittle. The tooth may have cracked. A bad taste is never a good sign. Right now, you have an infection. Bacteria is going into your mouth and you are swallowing it. And bacteria is getting through your body from the tip of your roots via your blood vessels. If you have any problems, i.e., heart murmur, systemic diseases, this is why taking care of your teeth is so important.
It is possible that your root canal is failing. You should seek out a second opinion.
I would suggest returning to a dentist for a re-evaluation of this tooth. My recommendation would be to schedule a consultation with an endodontist (a root canal specialist) to assure the best possible advice on the next steps to address your tooth.

To answer the question, an exam is required. See an endodontist for evaluation of the tooth, root canal and crown. There may still be infection, a missed canal, strong infection not responding, a periodontal (gum) problem, cracked tooth, another tooth causing it and so forth. Many possible reasons. The exact reason for you would require an exam.
Good luck.
