Oil gargling:

After cleaning your mouth and teeth, take 1 tbsp of oil or a little less (gingerly oil or

 sunflower oil) and gargle for five minutes (Move the oil inside the mouth). The oil becomes

 thin, impure and white in colour. Spit that oil and brush your teeth, clean your gums and

 mouth well. Gargle several times with water. Do not swallow that impure oil. Do this on an

 empty stomach. This cures many teeth related problems. It must be done regularly.
