If we need to stop existing cavities from becoming worse, we should obviously take care of our teeth by brushing them twice a day, flossing them everyday and cleaning the tongue everyday.
Another less obvious way we can care for our teeth is with oil pulling. According to www.top10homeremedies.com, there are three home treatment for tooth decay and cavities. The first treatment is mixing 2 to 3 drops of clove oil in with .25 tsp of sesame seed oil and putting a few drops of the solution on affected tooth. The second treatment is mixing 1 tsp of salt in warm water and swish in mouth around the affected tooth about three times a day. The third treatment is taking 1 tbsp of oil, such as sesame oil or coconut oil and putting in our mouth. Then swishing it around for 20 min. After 20 min, spit out the oil and brush teeth.
