Can Dental Cavities Heal Naturally?

This blog post will address the topic, “can dental cavities heal naturally” and cover topics like what is a dental cavity, stages of cavity formation and effective ways to heal dental cavities naturally in their earliest stages.

Can Dental Cavities Heal Naturally

The dental cavity forms in five stages. First stage is the formation of white spots on the tooth surface and preventive actions like toothbrushing with a fluoride toothpaste, daily flossing and mouthwash can reverse the cavity formation in this stage.

However, if ignored, the cavity development may enter into its later stages where reversal is impossible to achieve and root canal is the only favourable treatment option.

What Is A Dental Cavity?

Dental Cavity or tooth cavity, is a hole that develops on the surface of the tooth due to loss of mineral content from the enamel, resulting from the repeated acid attack by the plaque bacteria.

Stages Of A Cavity Formation

Consumption of sugary and starch rich foods expose the tooth to acids frequently, resulting in mineral loss from the enamel.

Infrequent tooth brushing habits cause poor oral hygiene, resulting in plaque accumulation.

Plaque is a sticky film containing bacteria that coats the protective enamel of your teeth. These bacteria produce acids by breaking down the food debris and the acids penetrate the enamel leading to formation of white spots on the teeth.

The cavity formation takes place in 5 stages:


  • Appearance of the white spots on the surface of the tooth as the mineral loss begins from enamel due to bacterial acid attack.
  • This stage can be reversed with preventive actions and maintaining good oral hygiene.


  • If the white spots are ignored and no preventive actions are initiated, the repeated acid attacks wear down the mineral and enamel is decayed
  • Visible hole is seen and now the cavity becomes irreversible.


  • The decay moves down further and attacks the inner soft dentin
  • This is called as Advanced Cavity Stage
  • Slight pain and sensitivity starts


  • In this stage, the decay finally reaches the pulp and irritates the nerves
  • Pain, sometimes excruciating, Sensitivity and Discomfort is seen in this stage.
  • Root Canal is the only treatment option other than extraction.


  • After pulp involvement, if treatment is not initiated, the infection spreads to the surrounding structures of the tooth and inflammation is caused
  • Extreme pain and even tooth loss may result

Ways To Heal Dental Cavities Naturally

If the cavity is just in its initial stage where the white spot is visible on the tooth, it is the time to take preventive actions such as toothbrushing, mouth washing and flossing daily.

At stage one, when the white spot has just appeared, the cavity can be reversed with proper oral hygiene and eating some mineral and vitamin rich foods.



It is recommended by the American Dental Association (ADA) to  brush your teeth twice a day for two minutes each time with a toothpaste containing fluoride. 

It is recommended to brush your teeth twice a day, once in the morning, just after waking up and once at night, just before going to bed.

You must also clean your teeth and gums, each time after you have food but not with a toothbrush. Simple rinse with water is considered good for overall oral health and hygiene.

Following this tooth brushing habit will help you prevent cavity formation in the first place and also heal a small cavity naturally in its earliest stage.

Do Not Immediately Brush after Eating Acidic Foods

You must wait for 30 minutes to one hour after consumption of acidic foods and drinks. The acid in the food or drink otherwise may erode the enamel layer and regular habit may cause exposed dentin leading to pain and sensitivity and increased risk of developing cavities.

Use Gentle and Short Strokes When Brushing Your Teeth

Use gentle, short strokes to brush your front teeth and thoroughly clean your mouth without abrading the enamel and preventing cavities from developing.

Brush the outside surfaces as well as the back molars and upper areas of your chewing surfaces. Brush the inside surfaces of both top and bottom front teeth by flipping your toothbrush upside down.

Brush your tongue to get rid of any bacteria or plaque.

Use a fluoride toothpaste

Fluoride can greatly help achieve oral and dental health by strengthening the tooth enamel, making it more resistant to tooth decay. 

Fluoride reduces the amount of acid produced by the bacteria on your mouth and also helps the cavity in its earliest stage to repair and heal. 

Floss Daily To Get Maximum Benefits Out Of Tooth Brushing

Many people, despite knowing the benefits of flossing daily, just neglect it.

According to a study, flossing is highly effective in reducing the interproximal caries risk. 

Daily floss can help stimulate your gums and reduce plaque leading to lesser inflammation risk and increased healing process of the cavity in its earliest stage.

Consider mouthwash

Therapeutic Mouthwashes contain ADA listed active ingredients such as fluoride, peroxide, essential oils, cetylpyridinium chloride, and chlorhexidine, preventing cavities from forming and naturally healing the formed cavity in its earliest stage.

Therapeutic mouthwashes as the name suggests have therapeutic action and control dental conditions like gingivitis, tooth decay and periodontal diseases. They also help remove halitosis.

Consult Your Dentist Twice In A Year

It is important to get your oral health checked twice every year with an interval of 6 months between two visits.

Your dentist can help remove calculus and locate cavities and will also be able to spot potential oral health issues, if any, and offer treatment solutions.

Fluoride treatments initiated in the earliest stages of tooth cavity may help it to reverse and heal.

Eat Foods Rich In Calcium, Magnesium, Phosphorus And Vitamins To Heal Cavities Naturally

Calcium Rich Foods To Heal Cavities Naturally

Calcium plays an important role in enamel remineralization and saliva production.

The remineralization process is essential for the cavity to reverse naturally.

Optimal saliva production acts as a natural cleanser and prevents plaque accumulation and acts as an adjunct in the process of healing cavity naturally.

All thanks to calcium rich foods like cauliflower, nuts, salmons and figs.

Magnesium Rich Foods To Heal Cavities Naturally

Magnesium is essential for remineralization of the enamel as well as to maintain a balance of minerals like calcium and phosphorus.

Magnesium deficiency will lead to enamel demineralization and weakening of the enamel, halting the natural healing of the cavity.

Leafy green vegetables, avocado and squash seeds are some magnesium rich foods that you can consider.

Phosphorus Rich Foods To Heal Cavities Naturally

Foods like meat, eggs and dairy products are rich in phosphorus and help in naturally healing the cavity in its earliest stage.

Vitamin D Rich Foods To Heal Cavities Naturally

Vitamin D is essential for calcium and phosphorus absorption in the body and its deficiency eventually wastes the calcium you intake.

Spending a few minutes in the morning sun gives an adequate amount of vitamin D to the body. However, foods like fish and egg yolks are rich vitamin D sources.

Vitamin D And Cavity Prevention: What Research Says?

According to research, children with vitamin D deficiency had an increased risk of developing enamel defects and tooth fracture.

Another clinical trial reported vitamin D to be a prominent agent for caries prevention.

Study published in the journal of dental research, concluded that vitamin D is essential for lowering the risk of developing caries in children.

FREQUENTLY ASKED QUESTIONS (FAQs): Can Dental Cavities Heal Naturally

Does Brushing Your Teeth Everyday Prevent Cavities?

Yes, brushing your teeth twice everyday for two minutes each time, prevents plaque buildup and is regarded as the simplest way of preventing cavities.

Why Do I Keep Getting Cavities If I Brush My Teeth?

You keep getting cavities even if you brush your teeth because either you are not brushing with a proper technique or there may be several pits and grooves present on the occlusal surface of your teeth.

The food particles get stuck in these pits and grooves, not possible to remove from brushing, resulting in plaque buildup, acid attacks on enamel by plaque bacteria and finally cavities formation.

Visit your dentist to get those pits and grooves sealed to prevent formation of cavities.

Why Do I Suddenly Have So Many Cavities?

You suddenly develop so many cavities because of the sudden change in your oral hygiene habits brought in by stress of a new routine or a new job.

Stress commonly results in dry mouth, which further results in quick plaque and tartar buildup, finally resulting in cavities at a faster rate.

How Fast Do Cavities Grow?

The cavities grow as fast as in six months or may take longer ranging from four to five years, depending on the condition of your oral cavity.

Do Cavities Spread?

No, cavities do not spread but may result from the same cause once again on another tooth.

Cavities do not spread from one tooth to another but may be caused by the same process and under the same conditions if proper treatment and oral hygiene is not maintained.
