How to Heal Cavities at Home? – 5 Natural Remedies

Dental caries or tooth decay forms as a result of an acid attack by the oral bacteria. The acid initiates the process of dental caries by causing loss of minerals from the tooth surface.

It is a common belief that if you’ve developed tooth decay, then you can only get it treated by a dental professional who will drill and fill to save the tooth.


However, what people don’t know is that there are natural remedies that you can follow at home to reverse your tooth decay and protect your teeth from the development of dental caries.

A study published in the British Medical Journal states that dental caries can potentially be prevented or even reversed by modifying the diet. (1)

It is clinically proven that a modified diet which contains equal portions of fruits and vegetables show a significant improvement in preventing dental caries.

In addition to a modified diet, there are other natural remedies that you can follow to prevent your teeth from the effects of dental caries.

In this article, we will cover the various causes of tooth decay, how can you prevent it, and how to heal dental caries at home.

What is dental caries?

Dental caries or tooth decay occurs as a result of demineralization of enamel caused by the acids produced by oral bacteria.

Some of the complications of dental caries may include infection of the pulp, inflammation of the surrounding tissues and eventually loss of a tooth.

Regular dental check-ups can help to detect the incipient carious lesions and prevent it from spreading further. (1)

What causes dental caries?

Three factors that are responsible for the formation of dental caries are –

The process of dental caries begins when an individual consumes food that is rich in carbohydrates and sugar. Oral bacteria thrive on these food substances and ferment them to produce acids.

Over time these acids attack the surface of the tooth, weaken the enamel and progress to involve the inner layers of the tooth structure leading to tooth decay.

This is one of the leading cause of dental caries. Some other factors may include –

  • Lack of essential minerals in the diet, for example, calcium, magnesium, and phosphorus (2)
  • Lack of certain vitamins necessary for strengthening the tooth structure like vitamin A, D, E, and K
  • Consumption of foods that contain a high quantity of processed sugars
  • Consumption of acidic foods
  • Poor oral hygiene
  • Lack of proper oral health care

How can dental caries affect oral health?

Dental caries can occur both in children and adults as a result of poor oral hygiene. The erosions caused on the surface of the tooth by the fermented acids allows the plaque to stick to the teeth and increase the bacterial load around the tooth surface.

When this condition is left untreated, dental caries can progress and involve dentin and pulp that can cause pain and discomfort to the patient.

Infected pulp is the root cause of tooth abscess formation which is a more painful and potentially severe oral condition.

What can you do to prevent and heal cavities?

Although only a dentist can diagnose a carious lesion or a cavity, you can detect the early signs of decay by looking at your teeth in the mirror.

Incipient caries is often seen as chalky white spots on the surface of the tooth that disappear when the tooth surface is wet and reappears when the tooth surface is dried.

Such initial spots can be reversed by following simple steps at home.

1. Say NO to processed sugar

Processed sugar is the main culprit in initiating the formation of dental caries in a healthy tooth. Sugar is the primary source of nutrition for oral bacteria.

A high intake of sugary food will increase the bacterial load in the mouth and will help them to produce acids that may cause demineralization of the enamel. (3)

To prevent tooth decay, you can switch to raw honey and maple syrup to add that sweetness in your food. Be careful to avoid food that contains artificial sweeteners.

2. Avoid food rich in phytic acid

Phytic acid is an enzyme inhibitor and a mineral blocker that is found commonly in beans, grains, and nuts.

It also has the potential to create several mineral deficiencies like calcium, phosphorus, iron, zinc, etc. In severe cases, it can even cause osteoporosis.

The ancient food preparation techniques involved sprouting and fermentation of the dough which helped to kill the phytic acids and make the food nutritious and useful.

But such food preparations are hardly followed anywhere and as a result, the consumption of phytic acid in our body is more. (4)

Phytic acid not only interferes with the absorption of essential minerals in the body but also leach them out from the bones and the teeth, thereby weakening their chemical structure and complicating the health conditions.

The best thing you can do to prevent tooth decay is to limit your grain consumption and stay away from unfermented soy products.

3. Include raw dairy and nutrition rich food in your diet

Natural dairy products, such as milk, cheese, and organic butter, contain a rich content of vitamins and minerals that help to maintain healthy teeth and promote good oral health.

They not only provide essential nutrients like vitamin D, K, calcium and phosphorous that strengthen the tooth structure but also help to neutralize the acids in the mouth.

Specific nutritious food that you can add to your daily diet is –

  • Fresh fruits – Eat at least one fruit a day
  • Raw and cooked vegetables with a special focus on green leafy vegetables
  • Food rich in healthy fats like coconut, avocado, olive oil, and cod liver oil
  • Better avoid raw grains or consume fermented grains like sourdough bread
  • Consume nuts and seeds in the form of sprouts rather than taking them as raw
  • Say NO to processed food and fast food

4. Use mineralizing or fluoride toothpaste

If you can get your hands on a good fluoride toothpaste, then it will help you to maintain the integrity of your tooth structure.

Fluoride chemically reacts with the enamel and strengthens it by providing the essential minerals that protect the layer and prevents tooth decay. (5)

You can even make mineralized toothpaste naturally at home. For this, you would need –

  • Four tablespoons of coconut oil
  • Two tablespoons of baking soda
  • One tablespoon of xylitol
  • 20 drops of clove essential oil or peppermint
  • 20 drops of trace minerals

Mix all the ingredients until they form a paste-like consistency and brush with this at least once a day.

5. At home ayurvedic treatment – Oil pulling

Oil pulling has recently gained attention among the population in the United States. It is an excellent method to prevent tooth decay.

It can be done at home by merely using coconut oil or MCT oil with 1-2 drops of clove oil or tea tree essential oil.

Take a tablespoon of the mixture and swish it in your mouth for a minimum of 20 minutes. (6)

Studies have shown several benefits of coconut oil pulling such as reduction in gingivitis, prevention of tooth decay and even improvement in frequent headaches and diabetes.

Oil pulling also maximizes the antiseptic and antifungal property, thereby protecting the teeth and the oral tissues from infections.


You can follow these simple steps to maintain the health of your teeth and gingiva –

  • The best time to do oil pulling is early in the morning, right after you wake up
  • Give yourself a 20 minutes’ time frame
  • Spit the oil out after 20 minutes and rinse your mouth with warm water. You can add salt for added antimicrobial effect
  • Thereafter, brush your teeth normally as you do every day

Take away message

Although there are professional methods of treating tooth decay and cavities, natural home remedies are always the best to follow.

They save you from the misery of spending money, time and energy. To take advantage of these natural remedies, you will have to keep a regular check of your teeth to detect tooth decay at an early stage.

Extensive cavitation and loss of tooth structure can be treated professionally by the dentist. Be informed about the various preventive methods and check if they are clinically approved.
