Cavities occur when acid destroys the underlying layer and the enamel of the tooth. This calcified tissue, dentin, is produced by exact types of bacteria.
Many people think that when tooth decay appear, it cannot be reversed. But that is not true.
Cavities can be reverse naturally on several ways.

Reverse Cavities And Heal Tooth Decay With The Help Of These 5 Steps
British Medical Journal published a research in which it is confirmed that cavities and tooth decay can be reversed with a certain diet.
This research involved 62 children with cavities. They were divided into 3 groups.
The children from the first group were on a diet with oatmeal and rich in phytic acid.
The second group consumed a normal diet with vitamin D as a supplement.
The third group was on a diet free of grain and vitamin D as a supplement.
Children from the Group 1, increased their cavities. Children from the second group had improvements, while the children from the group 3 had the biggest improvements. They ate a grain-free diet, food rich in nutrients and vitamin D as a supplement. Almost all of the cavities in children from third group were cured.
According to Dr. Weston Price, Dr. Edward Mellanby and Dr. Ramiel Nagel, 4 main factors contribute to tooth decay:
1. Deficiencies of minerals (magnesium, calcium and phosphorus)
2. Deficiencies of fat soluble vitamins (E, D, A and K)
3. Consuming a lot of food rich in phytic acid
4. Consuming a lot of processed sugar

Natural Ways to Reverse Cavities

1. Remove Sugar

If you want healthy teeth, avoid food that contains sugar. The oral bacteria that block a healthy flow of dental fluids is actually fed by sugar. Because it is highly acidic, sugar, also, demineralizes and decalcifies the structural content of the teeth.

2. Consume Nutrient-Rich Foods

To prevent tooth decay or even beat it, consume fat-soluble vitamins and minerals. The ideal diet would be with lots of leafy green veggies and food with high amount of healthy fats. Avocado, coconut oil, seeds and nuts are perfect for this diet.

3. Try Oil Pulling

Oil pulling is perfect for oral detoxification and it has been used throughout centuries. Rinse your mouth with one tablespoon of coconut oil, for about 20 minutes, and then spit it. If 20 minutes are too much for you, you can start with 3-5 minutes. Headaches, gingivitis and other health issues can be healed with oil pulling.

4. Eliminate Phytic Acid

Grains, beans, seeds and nuts, which are GMO or not organic contain phytic acid which inhibits enzymes in the body and blocks minerals. It can cause osteoporosis, mineral deficiencies and other health problems. Phytic acid blocks the mineral absorption from the food, and leaches the minerals out of the bones and teeth.

5. Use Mineralizing Toothpaste
