<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi My name is Swati, Age:-24 , weight:-60 k.g. I am having cavity in my tooth. Could you please what is the cost of filling the tooth with the best material. I have heard about some filling material that get filled through light immediately and that this is the best material for filling. I stay in pune India.  <response>: Thanks for your query, I have gone through your query. The decayed tooth can be filled with either silver amalgamstainless steel color or composite materialtooth color if the decay is not involving the pulp. Out of these two silver amalgam has better strength than composite but appearance wise composite gives exact tooth color. If it is front tooth go for composite, if it is back tooth then go for silver amalgam. The cost of the filling varies from 500 to 650 rupees. If the decay is involving pulp then it has to go for root canal treatment.
