Benefits of Hydroxyapatite for Teeth & More

List box[Hide][Show]

If you’ve been reading Health Mama for a while, you probably know that I enjoy dental health. The traditional advice is to use fluoride fluoride toothpaste to tighten teeth (and to prevent cavities) and a white toothpaste to deal with decayed teeth. But I didn’t believe it was the only (or best) way to protect my family’s dental health.

Then I discovered the benefits of hydroxyapatite, a substance that can whiten and strengthen teeth. A few years went by quickly, and I decided to use hydroxyapatite as an ingredient in my own natural toothpaste line. Since this name sounds very unusual, I thought it would be worthwhile to explain the benefits of this vast mineral and why I chose to include it.

I have a dive!

What is hydroxyapatite?

Although annoying to pronounce the name, it is actually a very simple material. Hydroxyapatite (HAp) is a calcium phosphate that makes up human teeth and bones. Pure hydroxyapatite is white, which is why healthy teeth are white.

Lab-produced hydroxyapatite (nano-hydroxyapatite-NHAP) has a hexagonal structure and a ratio of calcium to phosphate that is similar to that of human bones and teeth. Therefore, unlike some materials that are made in the lab, N-heap is as good as natural hydroxyapatite.

Hydroxyetate is also a stable form of calcium phosphate, which means that it is unlikely to be removed by a melting process such as oxidation. This is one of the reasons why it has been researched and used for so many medical purposes.

Benefits of hydroxyapatite

Hydroxyapatite is an interesting substance. According to a 2019 study, it has many benefits that make it suitable for medical and dental use. Create a helpful content.

  • Biological synchronization and biological – As mentioned earlier, hydroxyapatite is biologically similar to the substance that makes up human bones and teeth. For this reason, hydroxyapatite is not harmful to human tissue. It also has a biological effect, meaning it will help bones and teeth grow.
  • Osteoconductive – Hydroxyapatite is also an osteo-oxidative, meaning bone can grow at the level of hydroxyapatite, which helps repair hard tissues in the body.
  • Non-toxic – Hydroxyacetate is also non-toxic and does not cause inflammation. On the other hand, fluoride can be harmful.
  • Anti-microbial – HAP is also an antimicrobial, which can help fight infections and bacteria in the mouth, according to a 2018 study.

Researchers have long known that HAp had these benefits. But with advances in nanotechnology, it has become easier to create N-HAP in the lab, making it easier to use. Be more available.

Use of hydroxyapatite

Because of the many chemical benefits of HAp, it has been researched and used in both expected and unexpected ways.

Bone and dental surgery

Since HAP is what makes teeth and bones, it is understandable that it can help repair them. But the really interesting thing is that its use can help the body accept implants. It does this by implant coating. This coating convinces the body that the implant is already part of the body.

Research published in 2006 supports these uses. It also shows that HAp can help regenerate bones, so it can help repair broken bones.

A ten-year study published in 1999 found that HAp is completely safe and a very effective way to help implants survive in the body.

Dental health

Tooth decay can occur for a number of reasons, including acidic foods and beverages, a lack of adequate saliva, and excessive plaque. Hydroxyapatite makes up about 97% of tooth enamel and 70% of dentin (the bottom layer of enamel), so replenishing this substance is a great way to help healthy teeth. When used in toothpaste, nanohydroxypeptides are applied to the cavities in the teeth, strengthening them.

A 2014 review found that N-hip toothpaste has a “significant memory effect” on teeth – significantly better than fluoride.

The study noted that N-hip plaque also acts on bacteria and plaque, making them less troublesome to the teeth and helping to reduce NHAP sensitivity.

According to a 2009 study, HAp can also help whiten teeth. The researchers concluded that it is a very good alternative to bleaching agents. Considering that yellow teeth are the result of brushing, it makes sense that repeating can help improve whitening of teeth.

My whitened toothpaste contains aloe vera to whiten and improve teeth as well as aloe and green tea to fight bacteria and bad breath. We’ve been working with a team of researchers and product scientists for a long time to come up with a formula that is even better than our homemade toothpaste recipes.

Environmental use

The main uses of hydroxyapatite are medical and dental, but there is some research on other uses of this substance.

Air filters made from a combination of hydroxyapatite and 2 other chemicals can help absorb and dissolve carbon monoxide (CO) in the air.

Air quality (especially indoors) is a major concern for health-conscious families (including mine!), So this research is welcome.

Additionally, it can help remove fluoride from the atmosphere. Advertising is different from absorption. Advertising means that the fluoride binds like a thin film around the outside of the hydroxyapatite. This helps to remove fluoride from the atmosphere. Considering fluoride can have surprisingly negative effects (like pimples!), I always look for new ways to reduce exposure.

Is hydroxyapatite safe?

Both the 2019 study and the 10-year review have previously stated that there is no concern about safety with HAp when used in the methods described above. However, when used as a supplement, it can cause side effects such as headaches, dry mouth, frequent urination, fatigue, lethargy or sweating, and abdominal discomfort.

Good thing we all know not to swallow your toothpaste!

My family helps us whiten our teeth naturally by using hydroxyapatite in our toothpaste and we have had a great experience.

Hydroxyapatite: Bottom line

The technical name of this material makes it a little scary but it is far from harmful!

  • HAp is a safe and effective ingredient in natural toothpaste (for which I use it) but also for medical and environmental use. Can also be used.
  • Even when made in the lab, it is safe, effective and biological.
  • It can actually provide direct support to the bones and teeth and in some cases re-enforce it.

If you are looking for an alternative to fluoride toothpaste that actually works, I recommend using hydro-oxidized toothpaste like Valencia.
