Hello  sir, The cavities can be filled and treated go to a dentist and rule out whether it has reached the nerve if it has reached nerve then rct is required . And if can be treated with normal filling cost may vary from 800 to 1500rs.

Hi, yes cavities in molar teeth can be filled but dentist has to rule out if the decay has not reached the nerve / pulp as in that case u will require rct. Regarding cost , it depends on the material u choose for filling as it may range from 800/ to 2500/ My friend, nothing is complete for future , u have to maintain ur oral hygiene to avoid any cavities in future
