you can have a face to face discussion with your dentist , also see the equipment being used in the clinic  and once you get some confidence you can get the treatment done . this process will relieve you anxiety and fear. But if you dont do the treatment right now , you may have to undergo more complex procedures later on. bridgewaydental.com

Hello sir, filling a cavity is a very simple procedure which does not involve any pain or discomfort so you don’t have to worry. If the cavity is left untreated it may cause pain and discomfort later.

If you do not do filling in initial stage of cavity then it will go deep. Once pain begins, there are more chances of root canal treatment so get the filling done at the earliest. The more you delay... The more you will suffer. Now a days dentistry has become almost painless so don't be scared. Unfortunately there is no home remedy for tooth decay. Visit dentist for clinical examination and treatment.
