Last October I had a deep cleaning procedure done. A few weeks after I had my deep cleaning, one of my crowns started to throb and feel sensitive. I have had this crown for 4 years and it had never caused me pain until after the deep cleaning. I went back to the dentist and she said I needed a cavity filled next to the crown and that there was no issue with the crown itself. Got the cavity filled, but a few months later the crown started throbbing again.

I went to a new dentist and he did a few tests (cold air etc) and x-rays but couldn’t find a problem. He told me to take some ibuprofen and wear a mouth guard (I grind my teeth), and if that didn’t make it better I may need a root canal. It’s been a few months since then and the crown has started throbbing again and now when I bite down on it, it throbs more.

I’m going back to the dentist tomorrow, but my question is, could the deep cleaning have caused an issue with my crown? And are there other solutions other than a root canal? I don’t have my x-rays, otherwise I would have posted them on here. Thanks!
