16 Home Remedies to Get Rid of Cavities

home remedies for cavities

Oral hygiene is an important aspect of health. Strong and healthy teeth are attractive and people often search for ways to whiten teeth. However, maintaining the health of teeth is not an easy job. Bacteria feed on sugars from your food to produce acid which then attacks the teeth’s enamel, leading to gum disease and cavities. People believe that filling the tooth with a synthetic material is the only solution. This is not true as there are remedies to reverse tooth decay naturally. If you want to know how to reverse cavities, then help is here. Our home remedies to get rid of cavities can put your teeth into recovery, and not just stop the rot.

Home Remedies to Get Rid of CavitiesWhy do Cavities Occur?

Cavities, also known as caries, refer to small holes in the teeth. They are often a consequence of long-term tooth decay. Decay usually occurs due to an infection caused by Staphylococcus.

Infection due to Staphylococcus leads to demineralization of teeth. This causes the destruction of the hard enamel and leaves behind small, unpleasant holes.

It is often assumed that cavities are simply caused by eating too much sugar. While sugar no doubt plays a pivotal role in cavity formation, it is not the only cause and in order to prevent cavities forming, cutting down on sugar is not the only solution.

Cavities can be caused by:

Dry Mouth: Saliva is essential for oral hygiene. It prevents the growth of bacteria and the enzymes in saliva help digest food. If you get rid of dry mouth, you can prevent cavities.

Sticky foods: Foods that cling to the teeth, not just candy, can harbor the bacteria that lead to food decay. Potato chips (crisps), although they lack sugar, are particularly bad for the teeth.

Inadequate dental hygiene: Brushing and flossing are essential to prevent the formation of plaque and cavities.

Heartburn: Heartburn can cause stomach acid to regurgitate up into your mouth. Stomach acid will dissolve away the enamel of your teeth, exposing the underlying dentin of the tooth to bacteria and cavities.

Bulimia: Similar to heartburn, the constant regurgitation of one’s food due to bulimia exposes teeth to erosion from stomach acids.

Can you reverse cavities?

Cavities form due to a process called demineralization. Bacteria, living in dental plaque, consume food and sugars to create acids. These acids dissolve (demineralize) the enamel of the tooth.

Indeed, cavities only form whenever there is an acidic oral environment.

Many who wonder how to reverse a cavity, incorrectly conclude that once the enamel has been dissolved, there is no way the cavity can be reversed. i.e. you may be able to raise the PH of your mouth, cut out sweets and stop the decay, but once the enamel is gone, it’s gone for good.

This, fortunately, is not correct. You can reverse cavities naturally.

There are three important steps you need to do to reverse tooth decay.

  1. Lower the PH of your mouth from acid to alkali
  2. Ensure your oral hygiene provides a hostile environment for bacteria
  3. Ensure your diet has the minerals required to rebuild enamel and excludes foods that prevent mineralization.

When the oral environment is non-acidic, the process by which enamel reforms can take place.

Minerals are extracted from food, saliva, toothpaste, and mouthwashes and REDEPOSITED on the tooth.

These minerals will rebuild and repair the tooth’s apatite crystals, the basic calcified building block of the tooth. The repair will continue as long as the three rules above continue to hold.

All of the causes of tooth decay and all of the following home remedies for tooth decay effect one these three rules.

When using our home remedies to get rid of tooth decay, it is essential that you try at least one remedy from each group.

How to reverse cavitiesHome Remedies to get rid of Cavities

  1. Minimise phytic acid

phytic acid‘What is phytic acid?’, I hear you say.

Phytic acid is a compound found in nuts, seeds, grains, and beans. Phytic acid is a disaster for teeth as it is known to be a ‘mineral blocker’.

Nuts and pulse are rich in minerals but the presence of phytic acid means that most of these minerals are bound to the acid and unavailable for absorption by the body.

In particular, minerals essential for the reverse of tooth decay such as calcium, magnesium, and zinc are blocked by the acid.

Absorption rates of magnesium and zinc are some 60% and 20% lower respectively due to phytic acid. (1)

What’s worse is that this acid can leach minerals out of your system.

Long-term consumption of foods rich in phytic acid has been thought to cause digestive disorders,  nutrient deficiencies, and tooth decay. (2)

If you want to know how to reverse cavities and encourage mineralization, ensure that you limit your consumption of grains. For most people, this will mean eating less bread.

  1. Get Vitamin D

vitamin dVitamin D is an essential factor for absorbing phosphate and calcium from the diet.

Studies have established an inverse relationship between consuming vitamin D and cavities. [1]

This means that the deficiency of this essential mineral may lead to cavities. Hence, it is important to include foods rich in vitamin D as a part of your diet.

A study by the British medical journal looked at the effect of a phytic acid rich diet compared to a diet low in grains, but high in vitamin D.

The diet rich in grains and phytic acid showed a significant increase in cavities, while those on a vitamin D diet showed cavity reversal, with nearly all cavities, were healed. (2)

In order to reverse cavities, consider increasing your total sun exposure to get sufficient vitamin D.

  1. Yogurt

yogurtYogurt is packed with the vitamins and minerals that are needed to reverse cavities naturally.

Loaded with calcium, vitamin D, vitamin K, magnesium, phosphorus and fat-soluble vitamins, you should try and consume yogurt at least weekly as part of your strategy to reverse cavities.

Studies on yogurt consumption on Japanese children and cavity formation showed a direct link between lower levels of yogurt consumption and a higher incidence of cavity formation. [12]
