“They sure are handy when you smile, So keep your teeth around a while!” – Dr. Seuss

Can you guess what’s one of the most common non-communicable diseases to affect half of the world’s population? We have two words for you: oral issues. According to the World Health Organization(1) (WHO), around 3.58 billion people suffer from oral problems, with Cavities (dental caries) being the foremost condition.

But the surprising part is not this. The primary cause of poor oral health is “behavior-driven” which includes indulgence in unhealthy, sugar-heavy diets, high tobacco consumption, lack of minerals in your diet, alcohol abuse to name a few. Add to the mix, poor dental hygiene standards and insufficient exposure to fluoride, and we’ve got a real problem at our hands – one that won’t be able to save you by the skin of your teeth (pun intended).

In this section, we will address one of the frontrunners when it comes to tooth-related problems: Cavities. Simply put, a cavity refers to a hole in the tooth (caused due to tooth decay) that grows larger and deeper with time, if left unaddressed.

It typically occurs due to plaque – a sticky germ-like substance which specializes in tooth decay. It is believed that a build-up of plaque along with acid causes teeth to break down and eventually cause holes.

If there’s one takeaway that you should learn from this section, it is this: Cavity is completely preventable by natural means, as well as oral and lifestyle changes.” So here, we will outline all the natural means available at your disposal when addressing the question: “How to get rid of Cavities?”. Let’s get started.

CURE 3: Home Remedies for Cavities

You may be wondering about how to stop Cavities using home remedies or rather if it’s even possible to do so. Let us tell you that it is possible if the decay is at the “pre-cavity” stage – when holes have affected the tooth’s enamel but have not yet reached the dentin. The following remedies help strengthen the tooth’s enamel – also known as remineralization – and so they can be integrated into your daily oral care routine to prevent a cavity from forming altogether.

1. Oil Pulling

Oil pulling is an age-old Ayurvedic practice that dates back to 3,000 years.

Additionally, here are some easy-to-implement lifestyle changes you can make to ensure the benefits of a healthy oral system:

  1. This one’s obvious but not a lot of people do it despite knowing that they should: brush your teeth twice a day or else resign to a life of “toothy” problems.

CURE 5: Supplements for Cavities

Our bodies are naturally designed to heal and fight infections, including oral issues. But sometimes, when it lacks the proper nutrients, a supplement is required to fill in the gap (pun intended). There are a number of supplements available today that play a beneficial role in strengthening your teeth, mouth, and gums.

1. Vitamin D

vitamin d

A study(5) conducted in 2013 suggests that you can stop Cavities in teeth or reduce its occurrence by taking vitamin D supplements. In fact, further studies suggest that a deficiency in vitamin D levels can cause dental caries.

Why Does This Work?

As you may have guessed, Vitamin D extends a mineralizing effect on the affected tooth/teeth and this helps strengthen the tooth enamel.

How to Consume?

It is generally taken as an oral supplement to be most effective.

How Much to Use?

Please consult your doctor to understand the recommended dose for vitamin D supplements.

2. Calcium


We all know that calcium plays a vital role in maintaining healthy teeth and gums while bonding with tooth enamel and aiding in remineralization. Just like Vitamin D, it has been seen that a diet that’s calcium deficit could cause tooth decay.

Since the body is nutrient-deficient, it tends to pull calcium from the teeth – a very bad sign. This eventually leads to tooth decay. To that end, a study by the Journal of Periodontology claims that those who have a calcium intake of less than 500 mg were almost twice as likely to have periodontitis, or gum disease. The jawbone is particularly at risk.

Why Does This Work?

A study published in 2013 predicted that toothpaste containing arginine, a calcium compound could fight Cavities better than standard toothpaste.

How to Use?

It is most effective when taken as a supplement however, calcium is also found in foods like milk, cheese, yogurt, fish (sardines, salmon), kale, broccoli etc.

How much to consume?

The Food and Drug Administration recommends 1,000 mg of calcium for women younger than 50 and for men of any age, and 1,200 mg for women over 50, all of these should be taken in divided doses.

Don’ts for Getting Rid of Cavities

Here are some common “Don’ts” you need to focus on for a rock solid oral regime and for getting rid of Cavities from the root source (pun not intended):


Don’t ignore the following areas when brushing your teeth/massage them as this is where plaque builds up quite easily:

  • Cracks, pits, and grooves.
  • Between the teeth.
  • Around fillings, especially if chipped or broken.
  • Nearer to the gum line.

Don’t consume sweets, refined carbs (like bread, pasta etc.), energy drinks, coffee, breakfast cereals, cereal bars, dry fruits that tend to stick to the teeth easily, ice, soda, chips, and alcohol as they can all cause tooth decay.Don’t dehydrate yourself as saliva acts as a buffer between your teeth and the bacteria.

Also, dry mouth can create an imbalance for your mouth’s remineralization process – something that works in favor of the Cavities.Don’t miss those regular body check-ups since a deficiency in vitamin A, D, and phosphorus can lead to tooth decay.Don’t ignore your vitamin K2 intake as this is an extremely useful nutrient for achieving healthy teeth.Don’t eat foods with too much of phytic acid such as beans, grains, plant seeds etc.


1. Can Cavities Heal on Their Own?

In one word: “yes.” If the Cavities have not advanced to the dentin of the tooth, they can heal with a little intervention from the person’s end. You can follow the steps mentioned above to treat Cavities and remove them for good without any surgical intervention.

2. Do Cavities Hurt?

Typically, Cavities don’t hurt if they’re small in size. If they become large, they may hurt as they can cause tooth fracture or damage the nerves. Remember that an untreated cavity can lead to an infection called tooth abscess.

3. Are Cavities Contagious?

Yes, Cavities are contagious. Since the bacteria-causing cavity produces acid and destroys the teeth in the process. These germs are contagious with children and infants being extremely vulnerable to it.

4. Can You Reverse Cavities?

Depending on the extent of damage, cavity reversal is possible. However, the primary focus should be on nutrition first and dental hygiene comes second. Please consult your doctor to understand the best way to get rid of them – naturally or surgically.

5. Do Cavities Cause Bad Breath?

Yes, Cavities can cause bad breath mainly because cavity-causing bacteria tend to stay in areas that cannot be easily reached. If the tooth decay process begins and is left untreated, it leads to an accumulation of dental plaque in the cavity. This eventually spreads to the pulp, causes pulp death, and emits a foul odour or bad breath.

One in four adults in the US have Cavities, and more than half of teenagers have had Cavities(6).

Nature and natural means are the best chance we have to preserve our teeth and gums – unless it’s too late to do so. Remember that Cavities don’t appear overnight post a sugar-rich indulgence. They take months or even years to form and are generally a result of your oral microbiome, your diet, oral habits, pH level in your mouth, your saliva quality, among other things. Simply, it’s really because of long-due attention towards your dental care.

But with a little bit of effort, consciousness, and dedication, you can stop Cavities from ruining your mouth, and your life. If your oral issues persist despite the measures mentioned above or if you feel that none of the natural treatments is working in your favour, please consult your doctor for understanding the next steps you should take.
