Does my son require dental filling for deep molar fissures?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My son's dentist recommended filling his molars because they are very deep. But there is no cavity or other problem, and he takes good care of his teeth. So it is a preventive measure. But I am concerned about putting in a filling to prevent filling in the future. I worry about long-term issues like cracking of the filling or decay. Can filling the tooth cause any damage and make the tooth more vulnerable to decay? Can they use sealing material as they did when he was young? Kindly help.

Hi,

Welcome to icliniq.com.

I understand your concern.

Please trust the decision made by the dentist for your son. I suggest uploading a picture so that I can guide you properly. Sometimes the pits and fissures may be deep, making it vulnerable to caries. So in such cases, a filling might be required. Also, some caries are not visible outside, and some may not be black.

I hope this helps.

Thank you.
