Hi Sir, There is a possibility of secondary caries, so it's important to consult with a dentist and get an X-ray to confirm that there are no cavities. If no caries are found, there could be other causes for the issue, but without a proper oral examination, it's difficult to draw any conclusions. If necessary, a root canal may help relieve the pain, but the exact procedure cannot be determined without a proper diagnosis."
Next Steps
Consult with your dentist get an xray and let them identify the proper root cause.
