Hello We need to check if the hole is small or reached the nerve if it’s fine then filling can be done otherwise rct X ray will give the perfect treatment plan

Hi Better u visit nearest dentist because it's depends on cavity depth. It's very important to check clinically and Need X-ray also

First of all it is important to check the depth and extent of that hole. It can be done clinically and with the help of a X ray of that tooth. If there is any history of pain associated with that tooth treatment plan will change. Cost and treatment duration can be told only after above mentioned evaluation. So, visit any nearby dentist to avoid further problems.
