Prevention
Prevention methods include gargling with salt water, cider vinegar, dissolvable paracetamol or a non-alcohol-, non-sugar-based mouth wash. Always maintaining good oral health is key
Some alternative practitioners state that reducing the amount of white sugar or dairy in the diet will reduce the frequency of buildup. There is, however, no reliable data that supports this theory.
Tonsillectomy
Surgically removing the tonsils is the only permanent solution for tonsil stones -- this is also one of the most painful recoveries known. Your throat will initially feel sore, then about a week after the surgery you will want to die. Scabbing and black mucas start and seem to never end but after three weeks you are feeling normal again. If you choose this option, be ready to take 2-3 weeks off of life; also having a friend or family member take care of you is a huge plus since you will be doped up the whole time.
Laser Tonsillectomy
A longer term cure is possible by using laser resurfacing. The procedure is called laser tonsillotomy, or laser tonsillectomy. This technique can be performed under local anaesthetic, using the scanned carbon dioxide laser, which vaporises and removes the surface of the tonsils. In this way, the edges of the crypts and crevices which collect the debris, are flattened out, so that they can no longer trap material. Therefore stones, which are almost like pearls forming from a grain of sand, cannot form.
