Hydroxyapatite powder is a naturally occurring mineral found in teeth and bones. It’s composed of calcium, phosphate, and oxygen—all substances readily absorbed by the body when consumed as supplements.
HA powders are characterized by their average pore size, pore interconnectivity, and pore shape. These properties make them suitable for bone grafts and scaffolds that guide new tissue growth.
It Helps Remineralize Teeth
Hydroxyapatite powder helps remineralize teeth by filling in the tiny cracks 6that form on your tooth enamel. It does this by forming a chemical bond with the calcium and phosphate in your saliva. These minerals are the building blocks of tooth enamel and dentin and are responsible for your tooth’s hardness.
Demineralized teeth can lead to cavities and other dental issues, and remineralization is the way to prevent it. This process is usually aided by fluoride in toothpaste or mouthwashes. However, hydroxyapatite is different because it can bond with your teeth and rebuild the tooth from the inside out. This results in a stronger, more durable, and smoother tooth surface than fluoride alone.
Hydroxyapatite is made naturally in your body by the bones and teeth but can also be lab-created. It has a structure and ratio of calcium to phosphate similar to your teeth and bones. This is one of the reasons it is so effective in remineralizing teeth. Hydroxyapatite is also biocompatible and safe to use in your mouth.
The remineralization process requires more than just hydroxyapatite, though. It requires all the necessary minerals for your teeth to be healthy, including calcium and phosphorus, magnesium, trace elements, and essential cofactors like vitamins A, D, E, and K. This is why you need a whole-body approach to oral health, which includes a balanced diet, supplements to increase your vital minerals, regular dental cleanings AND the right oral care products.
In addition to remineralizing your teeth, hydroxyapatite also helps reduce the acidity in the mouth. The main reason for low mouth pH is the digestion of sugars by bacteria in your mouth, which produces lactic acid, which reduces your normal mouth pH. Hydroxyapatite can help raise your mouth’s pH to the level it should be to protect your enamel from the acid that wears away at it and leads to decay.
Hydroxyapatite is highly absorbent and can be used as a mouthwash or toothpaste. It is a gentle, natural alternative to other treatments and mouthwashes that are harsh on the teeth and gums.
It Helps Control Bacteria
Hydroxyapatite is a naturally occurring mineral that is the main component of bone and teeth. It’s biocompatible and biologically active, meaning that it helps teeth and bones to repair themselves. This is what makes hydroxyapatite so effective for remineralizing teeth, preventing cavities, and even reducing tooth sensitivity. It’s also antibacterial, preventing bacteria from adhering to the surface of your teeth and causing decay.
Hydroxyapatite does this without destroying the oral microbiome, which is essential for your mouth to function correctly. This is a big difference from fluoride, which can kill bacteria in the mouth and disrupt the balance of good and bad bacteria.
When used in toothpaste, hydroxyapatite powder prevents the acid in plaque from attacking the enamel of your teeth, preserving the health and strength of your enamel. It does this without using harsh chemicals like chlorhexidine or alcohol that destroy healthy bacteria and cause more problems than they solve.
Hydroxyapatite powder can also attract and hold calcium, making it the perfect ingredient for remineralizing and strengthening teeth. It’s also non-toxic, so it won’t damage your enamel or create any sensitivity problems in the long run. It’s a great alternative to fluoride, which has been linked to many issues in the body.
EPRUI’s hydroxyapatite nanopowder is high quality and food grade, with particle sizes of 60nm, 200nm, and 2um. It can make many products, including dentifrice, toothpaste, and mouthwash.
It’s a straightforward material so that you can incorporate it into your formulations easily. The hydroxyapatite powder can be dissolved in water or other liquids to form a paste or gel. It can then be shaped or ground into a fine powder.
After the hydroxyapatite solution is shaped, it can be dried into a solid. This is done by heat or air drying. This process can be repeated as needed to make additional hydroxyapatite powder. This powder can then be mixed with other ingredients, such as glycerin and sodium benzoate, to make a toothpaste or mouthwash.
It Helps Prevent Caries
Hydroxyapatite is a natural calcium phosphate compound that makes up most of your teeth’s enamel structure. It is also a key component of bone tissue. Thanks to advancements in materials science and nanotechnology, it is now possible to produce hydroxyapatite in the lab for medical uses.
Our body’s natural chemistry recognizes this material, and it can be used to strengthen teeth or replace tooth enamel that has been lost due to damage or cavities. The result is stronger teeth, less prone to tooth decay, gum disease, and more.
Unlike fluoride, a toxic chemical that can be swallowed or inhaled, hydroxyapatite powder is entirely non-toxic and safe for humans. It can even be used to remineralize teeth damaged by cavities or other dental procedures.
In addition, hydroxyapatite’s structure provides a barrier against acids that cause tooth decay. As a result, it can prevent bacterial action that would otherwise wear down the enamel, allowing plaque to penetrate deeper into the tooth and lead to cavities and gum disease. Hydroxyapatite has been shown to reverse the early stages of tooth decay, called caries or enamel demineralization, which is the first step toward developing cavities.
Hydroxyapatite is also effective at controlling plaque that causes gingivitis. This is because it can help neutralize the acid that breaks down the enamel and exposes the dentin, causing gum recession or tooth loss. Hydroxyapatite also has anti-inflammatory properties that can help control bleeding gums, bad breath, and inflammation.
To make hydroxyapatite, the calcium nitrate tetrahydrate [Ca(NO3)2.4H2O] and di-ammonium hydrogen phosphate [(NH4)2HPO4] are coprecipitated by dispersing them in deionized water (DI) solution. The resulting residue was dried and ground into a fine powder. The morphology of the hydroxyapatite was examined using a scanning electron microscope (SEM), and the network composites with different HAP content were analyzed by transmission electron microscopy (TEM). From the SEM and TEM images, it was found that the hydroxyapatite nanopowder agglomerated into spherical chunks with smaller individual particles. Moreover, the X-ray diffraction pattern of the network composite with 30% HAP content matches the characteristic peaks of the hydroxyapatite crystal.
It Helps Control Plaque
Hydroxyapatite (HA) is a naturally occurring mineral that contains calcium and hydroxyl ions in varying ratios. It crystallizes in a hexagonal system and is white. It is also found in the bones of humans and other mammals, as well as the sand of rivers, lakes, and oceans. It can be used in several applications, including medical and dental procedures. HA powder is helpful in dentistry because it can help remineralize teeth and reduce tooth sensitivity. It can also help control plaque and prevent gum disease. It is non-toxic and low pH, making it ideal for oral health.
It has been shown that HA is bioactive and osteoconductive, meaning that it can form direct chemical bonds with living tissue. This makes it perfect for dental applications since it can stimulate bone growth and remineralize the teeth. HA is also non-toxic and has no negative impact on the environment. It can be made into various shapes and sizes to suit different needs.
The stoichiometric HA is a raw material for producing bone-grafting and infill materials for bone defects to improve osseointegration in human and animal bone structures [1]. It is a highly stable substance that has a melting point above 1000°C, which makes it suitable for use in 3D printing, thermal spraying, and bone scaffold twin screw extrusion [2].
A variety of factors can influence the morphology of hydroxyapatite, including its chemical composition and structure. To control these parameters, a synthesis process is often employed. Using this method, stoichiometric HA can be produced in large quantities with a high degree of uniformity.
To investigate the crystal morphology of stoichiometric HA, it was subjected to transmission electron microscopy (TEM). The results showed that HA has a needle-like shape and is composed of interconnected pores. Moreover, the selected area diffraction pattern showed that HA has a polycrystalline ring and a strong peak at the (002) plane, which indicates that the HA consists of hexagonal phases. In addition, the HA had a smaller crystallite size and a higher crystallinity than fluorapatite.
