The Science Behind Hap Toothpaste: A Comprehensive Review



Explanation of what Hap is

Hydroxyapatite in its natural form is a type of calcium that makes up 97 percent of tooth enamel and 70 percent of dentin. The few remaining substances are water, collagen and other proteins. Hydroxyapatite is also the main (60%) component of bones. In addition to being used in toothpaste, as a cutting-edge new material in biomedical technology, it is also widely used in bone tissue regeneration, calcium supplements and other fields to help strengthen bones. It is also a cutting-edge new material for orthodontics, implants, and restorations.


What Hap Toothpaste is

Hydroxyapatite (HAP) can be used in toothpaste. The main appeal is to remineralize (rebuild) tooth structure and thus restore tooth enamel without any known toxic side effects.


When the teeth (firstly the enamel) are affected by oral respiration, food residues, oral hygiene, and finally the oral flora, the formation of plaque continues to erode and demineralizes the teeth, forming dental caries (cavities).


To reverse caries through remineralization and prevent new caries from forming, the use of hydroxyapatite-rich toothpaste is a very effective method. In Japan, researchers have conducted field comparative studies, and the caries rate of primary school students who use hydroxyapatite-containing toothpaste has been reduced by 36-56%. The Japanese government has officially certified that hydroxyapatite can repair minor damage to enamel and restore the transparency of enamel, and reverse early caries!

Brief history of Hap Toothpaste

Hap Toothpaste was first developed in Japan in the 1970s as a way to help people maintain healthy teeth and gums. Since then, it has become increasingly popular around the world, with many people using it as an alternative to traditional toothpastes.



The Science Behind Hap Toothpaste

Composition of Hap Toothpaste

Hap Toothpaste is made from hydroxyapatite (HAp), which is a naturally occurring mineral that is found in teeth and bones. HAp has been shown to be effective in preventing dental caries and improving gum health. Hap Toothpaste also contains fluoride, which is a mineral that helps to strengthen tooth enamel and prevent tooth decay. Other ingredients in Hap Toothpaste may include xylitol, which is a natural sweetener that can help to prevent tooth decay, and other natural ingredients that are designed to promote oral health.


How Hap Toothpaste works

The core function of hydroxyapatite (HAP) is to replace the calcium lost during tooth demineralization, and to fill the invisible micro scratches on the surface of enamel, preventing these micro scratches from becoming plaque attachment points.


Because our teeth can recognize hydroxyapatite, they can absorb and import this component into the deep layer of tooth enamel, right to the bottom area of caries, rebuild our tooth enamel, and thus have the effect of reversing caries. If dental caries has touched the junction of enamel and dentin, it will lead to the exposure of the nerve tubules in the corresponding parts, block these exposed parts and remineralize, which will reduce the possibility of exposure of these nerve tubules, thereby alleviating tooth sensitivity.


The reconstructed and strengthened tooth enamel is more resistant to the adhesion of dental plaque and the erosion of acidic substances, the surface of the tooth will become smoother and smoother, and the color will return to the original color of tooth surface enamel.


Interestingly, hydroxyapatite molecules also have a strong tendency to bind to proteins, which can effectively adsorb oral bacteria, dental plaque and pigments, and nano-sized hydroxyapatite (nHAP) can further expand the adhesion to proteins surface area, the adsorption force is stronger.


Benefits of using Hap Toothpaste

· It prevents and heals cavities.

· It has no toxic side effects and is biocompatible.

· It helps to restore tooth surface smoothness and natural luster (healthy white)

· It helps balance oral flora.

· It can effectively balance the pH value in our mouth

· It helps improve gum health



To summarize, Hap Toothpaste is a safe and effective method of maintaining oral health. It is made of hydroxyapatite (HAp), a mineral found naturally in teeth and bones, and it has been shown to be effective in preventing dental caries and improving gum health. According to clinical studies, Hap Toothpaste is more effective than other toothpastes in preventing dental caries and improving gum health. Hap Toothpaste may be the right choice for you if you’re looking for a safe and effective way to maintain your oral health.
