Strong teeth are healthy teeth

If you've experienced enamel loss, cavities and decay, you may be wondering how to remineralize teeth and repair enamel to avoid further damage to your teeth. Although we don't have a magic solution that can regrow teeth or grow back enamel damaged by decay, the good news is that there are ways to naturally strengthen teeth and remineralize enamel.

This might involve tweaking your diet, adopting a few healthy habits, and using a remineralizing toothpaste. There are various home remedies that can help remineralize and strengthen teeth, too. And if you are serious about enamel repair and tooth remineralization, you can also cut down on certain foods, for example, those with phytic acid in them.

Of course, the number one way to care for your teeth is with a good oral hygiene routine. But if you're doing everything right there and still experiencing poor oral health and tooth decay, this article explains some other things that might help make your teeth stronger.

How to restore tooth enamel naturally with remineralization

When it comes to keeping teeth healthy, you pretty much know the drill: avoid cavities, brush them twice a day, floss, and of course, keep yourself miles away from sugary snacks. So it's naturally frustrating when, even after following this standard advice, you still get tooth decay. What could you possibly still be doing wrong? Probably not paying attention to tooth re-mineralization.

Brushing well is important but there are other things that help

People often ask “Does enamel grow back?” and “Can you regrow tooth enamel?”. The short answer to all of these is ‘no' – enamel damaged by decay cannot simply grow back. However, it is possible to restore the minerals in weakened enamel and make your teeth more resilient to decay. This is a process known as ‘remineralization'.

Below we describe the best ways to remineralize and strengthen teeth naturally, and also explain some of the things that are weakening them in the first place.

Avoid foods with phytic acid

During the 1930s, a famous dentist named Weston Prince set out to study the dental health of people living in remote areas with little or no contact with civilization. The dentist was astonished to discover how most of these people had good oral health with very rare cases of tooth decay and dental caries. As he investigated the reason, he stumbled upon a common thread: all these people ate a diet loaded with whole foods like fatty meat, wild-caught fish, vegetables and fruits, and whole-milk dairy products while avoiding certain grains and legumes.

What is so wrong with grains and legumes? Despite being very healthy (whole grains), they are rich in phytic acid, a known “anti-nutrient” that binds itself to minerals present in the body such as zinc, calcium, and iron and prevents their absorption. Simply speaking, the more grains you eat, the more phytic acid your body acquires which ultimately causes damage to the tooth enamel and increases the chances of tooth decay.

So, if your goal is remineralize teeth and protect your enamel, you can try going legume and grain-free for some time to reduce phytic acid levels in the body and give it a chance to absorb all the primary minerals. While you do this, here are some great foods to include in your diet:

Eating healthy can help remineralize teeth
  • Grass-fed meats
  • Pastured eggs
  • Wild-caught fish
  • Healthy fats from coconut oil and grass-fed butter
  • Organic vegetables

Of course, before making any drastic changes to your diet, it's always best to consult with your physician.

Heal your gut with probiotics

Consuming mineral-rich foods is not the only way to strengthen and remineralize your enamel. There are many other things that you may consider adding to your diet for a healthy mouth; one of which is probiotics.

Probiotics are the good bacteria present in your gut which not only protect your digestive system but can also reverse tooth demineralization and prevent cavities. This may not come as a surprise, especially after the release of studies like this one that demonstrate how almost every disease in the body can be linked to gut issues.

But why should you include probiotics as a part of your oral care? What part do they play in remineralizing teeth and enamel repair?

Probiotics decrease the number of mutans streptococcus, a kind of bacteria found in the mouth that plays a primary role in tooth decay. Additionally, they also keep your gut healthy which means it is better able to absorb the majority of nutrients and minerals.

According to recent studies, the following probiotic strains can help you maintain healthy teeth:

  • Lactobacillus reuteri
  • Lactobacillus salvarius
  • Bifidobacterium animalis
  • Lactobacillus rhamnosu

Remember to include a high-quality probiotic supplement with the above-mentioned strains in your daily diet if you want to strengthen teeth.

Take the right vitamins for teeth

Vitamin D is an important nutrient, not only for your dental health but also for other body systems. It helps the body to absorb calcium which strengthens the joints, bones, and – you guessed it – teeth. While most of us are well aware of its importance, not many people make sure to get enough of this vitamin.

Scientists have found that supplementing your body with vitamin D can greatly reduce the likelihood of getting cavities. You may also consider taking vitamin K2 after seeking appropriate medical advice as it considerably enhances the absorption of vitamin D.

Use baking soda

Baking soda is an extremely popular and effective home remedy to whiten the teeth. It has even been recommended by dentists as a safe natural alternative to commercial teeth whiteners. But did you know that baking soda can also help you prevent cavities and maintain good oral hygiene?

What's more, baking soda also reduces acidity in the mouth which may otherwise disrupt the layer of minerals naturally deposited on the enamel of a tooth. A reduced acidity level makes it easier for fluoride toothpaste to remineralize and rebuild the enamel, too.

So if you think your teeth need a quick remineralization, all you need to do is mix one tablespoon of baking soda with 120ml of water and swish it around your mouth once a day.

Perform coconut oil pulling

Oil pulling is a famous Ayurvedic practice that not only strengthens the gums and teeth and freshens the breath, but also helps remineralize teeth and prevent tooth decay. Numerous studies have proven that using oil can clear away the harmful bacteria, such as streptococcus mutans, which normally reside in the saliva and plaque.

Just take one tablespoon of coconut oil and swish it in your mouth for 20 seconds per day. The traditional Ayurveda recommends using sesame oil but for most people, coconut oil is a better choice as it has a better taste.

Try Xylitol

Xylitol is a natural sweetener that comes from the birch tree. In addition to sweetening up your everyday foods, xylitol is also considered an important substance to remineralize teeth and protect the enamel. Xylitol helps maintain good dental health in a number of ways:

  • Kills bacteria by starving them to death
  • Greatly increases the absorption of calcium
  • Raises the pH of salvia making it more favorable for remineralization

Xylitol is found in some toothpastes (see below) and can also be taken as a supplement. Talk to your dentist about how much xylitol you can safely consume to remineralize teeth in the fastest way possible.

Use a remineralizing toothpaste

Regenerate Enamel Science remineralizing toothpaste

In addition to altering your daily diet and using natural remedies, your dentist may also recommend using a special remineralizing toothpaste to strengthen your teeth. Sensodyne Repair & Protect is a good budget option, containing calcium and fluoride to protect and remineralize teeth.

A more advanced brand of remineralizing toothpaste that's still quite easy to find on the high street is Regenerate Advanced. The special NR-5 formula has been clinically proven to reverse early enamel erosion and remineralize the teeth.

Regenerate also offer this tooth enamel repair kit which includes the toothpaste plus their Advanced Enamel Serum – an intensive remineralizing gel which you use in the mouthpiece provided for just 3 days a month.

Hydroxyapatite toothpaste

Hydroxyapatite is a type of calcium that occurs naturally in your body. This mineral comprises almost 70% of your bones and is also the main mineral present in your tooth enamel. When your dentists tells you that you have weak enamel, what they actually mean is that it has lost a lot of its hydroxyapatite molecules.

Luckily, scientists have been able to synthesize hydroxyapatite molecules which are similar to the ones naturally found in the body. These calcium-rich particles are now being used for tooth enamel repair in people with loss of minerals to prevent cavities and poor oral health.

Toothpastes are probably the best and the most convenient products to get the maximum amount of bioavailable hydroxyapatite. So the next time you are shopping for toothpaste, you may want to get a toothpaste with bioavailable nano-hydroxyapatite crystals in it like this one from Apagard.

It's a premium toothpaste, costing quite a bit more than big-name brands, but hundreds of reviewers think it is worth it. One comments:

“Tastes good. Quickly making my teeth look healthier. Whiter, in a ‘thicker shinier enamel' way, rather than a ‘I've been bleached' way. Shiner, less translucent. I'm impressed and will repurchase.”

Fluoride toothpaste benefits

Hydroxyapatite might be the building blocks for your teeth, but then fluoride is the cement that holds the blocks together.

There are two reasons why fluoride toothpaste is the best remineralizing toothpaste for teeth enamel repair: it prevents the loss of minerals from enamel and prevent cavities, and it helps incorporate the hydroxyapatite particles into the teeth when used in combination.

The short video below demonstrates the dramatic level of protection that fluoride toothpaste gives. It could be a good one to show your kids – or even try yourself at home – if they are protesting about brushing properly.

Fluoride-free remineralizing toothpaste

If you prefer to avoid fluoride for whatever reason, here are a couple of fluoride-free toothpastes that still have other ingredients for remineralizing teeth.

Splat Biocalcium toothpaste reduces sensitivity and repairs enamel

First of all, Splat Biocalcium remineralizing toothpaste helps strengthen enamel, reduce sensitivity, and also whiten teeth gently. It contains hydroxyapatite and sodium bicarbonate (baking soda) which we mentioned above, as well as calcium. Here's what one happy customer says about the effect it has had on their teeth:

Very good effective healing toothpaste, I was starting to get toothache then I read an article on how you can heal your teeth naturally with this type of toothpaste & it's worked wonders FAST! I no longer have the toothache so it's saved me from getting a filling! I will continue to re-order this. It tastes ok too!

Another popular option is Pearlie White Active Remineralization Toothpaste. This contains hydroxyapatite micro-particles and xylitol to naturally remineralize tooth enamel. As well as being fluoride-free, it also contains no SLS, which is another ingredient some people like to avoid in toothpaste.

The whitening effect comes mainly from the tooth remineralization process, and the gentle stain removal it provides.

How does tooth remineralization help?

Now that you know how to remineralize teeth in the most effective ways possible, you must also understand why it is so important.

The biggest reason why you should remineralize teeth is that it helps reverse tooth decay and reduces the likelihood of cavities. But that's not the only benefit. Teeth remineralization can also:

Plus, it also positively impacts your overall health and may markedly improve your quality of life.

Optimising enamel repair

Always follow your dentist's advice first

Switching your toothpaste is a great start, but we've mentioned lots of other small changes you can make to help strengthen your teeth. If you're taking it really seriously, here are certain things that you can do to maximise tooth remineralization and fight off cavities:

Do not dabble

Be in control of your dental health by forming habits that automatically promote remineralization. Instead of searching for a quick fix, find sustainable solutions that you may adapt to your lifestyle.

Begin early

Remember that the habits that promote remineralization also play an important role in the healthy formation of teeth, and this goes for both temporary and permanent sets of teeth. So, it is better if you start early and don't wait until you already have cavities.

Stay hydrated

Hydration plays an important role when it comes to producing saliva, which is an important defence against plaque and cavities. Therefore, drink at least eight glasses of water every day to help avoid dry mouth and aid enamel repair.

Live healthily

Get enough sleep, control your stress levels, and exercise on a daily basis. These three factors not only promote general health of the body but also have indirect impacts on your teeth by regulating hormones and running all the body's systems effectively.

Cheat strategically

Even if you decide to have cheat days, do it strategically. For example, if you wish to drink a can of acidic soda that severely hampers the remineralization process, try finishing it quickly instead of sipping on it throughout the day.

Talk to your dentist

Even if you wish to stick to natural remedies to mineralize your teeth, do not forget to stay in touch with your dentist. Your dentist can help you with tracking your progress and documenting your results in addition to helping you gain access to products you may not find over-the-counter.

How to strengthen teeth: conclusion

Your teeth are an important part of your body and require constant remineralization. Your saliva naturally does a lot of the work for you, but sometimes we need to give our teeth a boost. The enamel repair strategies outlined in this article can all help strengthen your teeth and improve your long-term oral health.

Here's a summary of the things you can do to remineralize your teeth.

Oral hygiene Diet Lifestyle
Baking soda rinse Foods low in phytic acid Get enough sleep
Remineralizing toothpaste with fluoride Organic vegetables Exercise a little bit every day
Incorporate xylitol into your routine Healthy fats Drink 8 glasses of water every day

Don't forget to keep in touch with your dentist to track progress and keep a check on the results.

FAQs

man at the dentist for tooth enamel repair
Taking care of your mouth can be easy!

Can you regrow teeth enamel?

Unfortunately, it is not possible to restore or regenerate enamel because unlike bone or skin, it is a non-organic tissue that lacks the ability to grow. Moreover, there is no other source of enamel in the body that can be used for the process of grafting. However, tooth enamel that has been mildly damaged by demineralization can be repaired with some careful attention.

What can I eat to remineralize my teeth?

Foods rich in calcium, such as almonds, cheese, milk, and leafy green vegetables, can all help with tooth remineralization. Phosphorus-rich foods like eggs, fish, and non-processed meat can also contribute to this process.

Can baking soda remineralize teeth?

While baking soda does not directly mineralize teeth, it may aid the process. For instance, it reduces acidity in the mouth which may otherwise disrupt the layer of minerals naturally deposited on the enamel of a tooth. A reduced acidity level also makes it easier for fluoride toothpaste to remineralize and rebuild the enamel.

Can you reverse tooth decay?

A cavity occurs due to the loss of minerals from the enamel. This is definitely reversible in the early stages with the help of different remedies like baking soda, fluoride remineralizing toothpaste, and probiotics. However, if the process of tooth decay continues, more minerals keep getting lost, weakening the enamel, deepening the cavity, and causing tooth pain. At this stage, the cavity becomes irreversible and enamel repair requires a filling.
