What is Nano-Hydroxyapatite?

Hydroxyapatite (HAp) is a mineral that consists of calcium, phosphorus, and oxygen. It is the main component of bones and teeth, accounting for 97% of the enamel and 70% of the dentin. HAp is also present in saliva, where it helps to maintain the pH balance and prevent tooth decay.nano-hydroxyapatite before and after

Nano-hydroxyapatite is a form of HAp that has very small particle sizes, ranging from 20 to 80 nanometers (nm). For comparison, a human hair is about 80,000 nm thick. Nano-HAp can penetrate into the microscopic pores and cracks of the enamel and dentin, where it can bond with the existing tooth structure and form a protective layer.

How Does Nano-HAp Toothpaste Work?

Nano-HAp toothpaste works by delivering nano-HAp particles to the teeth during brushing. The particles adhere to the tooth surface and fill in the gaps and lesions caused by acid erosion, abrasion, or decay. This process is called remineralization, which means restoring the lost minerals to the teeth.

Remineralization is important for maintaining the strength and integrity of the enamel and dentin, which are constantly under attack from bacteria, acids, sugars, and other factors. When the enamel and dentin are weakened or damaged, they become more susceptible to cavities, sensitivity, discoloration, and infection.

Benefits of Nano-hydroxyapatite toothpastes

Nano-HAp toothpaste can help to prevent and reverse these problems by repairing the tooth structure at a nanoscale level. It can also enhance the appearance and function of the teeth by smoothing out the surface, reducing stains, increasing gloss, and improving hardness.

What are the Benefits of Nano-HAp Toothpaste?

Nano-HAp toothpaste has several benefits for oral health and hygiene. Some of these benefits are:

  • Cavity prevention: Nano-HAp toothpaste can inhibit the growth and activity of bacteria that cause tooth decay, such as Streptococcus mutans. It can also neutralize the acids that dissolve the enamel and dentin, thus preventing demineralization. Studies have shown that nano-HAp toothpaste can reduce plaque formation, lower caries risk, and increase enamel resistance to acid attack.
  • Sensitivity relief: Nano-HAp toothpaste can reduce tooth sensitivity by occluding the dentinal tubules that transmit pain signals to the nerves. Dentinal tubules are tiny channels that connect the dentin to the pulp, where the blood vessels and nerves are located. When the enamel or dentin is worn away or damaged, the tubules become exposed to external stimuli, such as hot, cold, sweet, or sour foods and drinks. This can cause sharp or throbbing pain in the teeth. Nano-HAp toothpaste can block these tubules with nano-HAp crystals, thus reducing or eliminating sensitivity.
  • Whitening effect: Nano-HAp toothpaste can whiten teeth by removing extrinsic stains from the surface of the enamel. Extrinsic stains are caused by factors such as smoking, coffee, tea, wine, or certain foods that can discolor the teeth over time. Nano-HAp toothpaste can polish away these stains with its abrasive action and restore the natural color of the teeth. It can also prevent new stains from forming by creating a smooth and glossy layer on the enamel that repels staining agents.toothpaste with nano-hydroxyapatite
  • Enamel strengthening: Nano-HAp toothpaste can strengthen enamel by increasing its mineral content and density. Enamel is composed of hydroxyapatite crystals arranged in a hexagonal lattice structure. This structure gives enamel its hardness and durability. However, this structure can be disrupted by factors such as aging, genetics, diet, or medication that can cause enamel loss or hypomineralization. Nano-HAp toothpaste can replenish the lost minerals and reinforce the crystal structure of enamel with nano-HAp particles that integrate into the lattice.

What’s The Difference Between Nano-Hydroxyapatite And Hydroxyapatite?

Nano-hydroxyapatite (nano-HAp) and hydroxyapatite (HAp) are both forms of calcium phosphate that have similar chemical compositions but different physical properties. The main difference between them is their particle size and surface area. The table below summarizes some of their characteristics:

Particle size20-80 nm1-10 µm
Surface area50-100 m2/g10-20 m2/g

As you can see, nano-HAp has smaller particles, larger surface area, higher bioactivity, deeper penetration, stronger adhesion, and lower abrasion than HAp. These properties make nano-HAp more effective and suitable for toothpaste applications than HAp.

What Do Other Users Say About Nano-HAp Toothpaste?

Nano-HAp toothpaste has received many positive reviews from users who have tried it. Here are some of the comments that users have shared online:

  • “I love this toothpaste! It has a nice minty flavor and leaves my teeth feeling smooth and clean. I have noticed that my teeth are less sensitive and more resistant to stains since I started using it. I also like that it is natural and fluoride-free.”
  • “This toothpaste is amazing! It has helped me with my sensitivity and cavities. My dentist was impressed by how much my enamel has improved. I also like that it whitens my teeth without harsh chemicals or abrasives.”
  • “This toothpaste is a game-changer! It has made my teeth stronger and healthier. I have less plaque and tartar buildup and no more bleeding gums. I also like that it is vegan and eco-friendly.”

If you’re going to develop Nano-Hydroxyapatite toothpaste for your brand, you’d better investigate more user reviews before formulating yours.

How Nano-Hydroxyapatite Helps Sensitive Teeth

Nano-Hydroxyapatite plays a beneficial role in addressing tooth sensitivity. Here’s how it does good to sensitive teeth:nanohydroxyapatite remineralizing toothpaste

  1. Protective Layer: Nano-Hydroxyapatite toothpaste forms a protective layer on the tooth surface. This layer acts as a barrier, covering exposed dentin, which is the sensitive layer beneath the tooth enamel. By shielding the dentin, nano-hydroxyapatite helps reduce the transmission of external stimuli, such as hot or cold temperatures, to the nerves in the tooth, thereby alleviating tooth sensitivity.
  2. Remineralization: Nano-Hydroxyapatite promotes the remineralization of tooth enamel. When the nano-sized particles come into contact with the tooth surface, they release calcium and phosphate ions that integrate into the enamel structure. This remineralization process helps strengthen the enamel and fill in microscopic defects, reducing the permeability of the tooth and minimizing sensitivity.
  3. Enamel Strengthening: By bonding with the natural enamel, nano-hydroxyapatite reinforces the tooth structure, making it stronger and more resistant to external irritants. This strengthening effect helps fortify the enamel and can reduce sensitivity caused by enamel erosion or thinning.
  4. Gentle Cleaning: Nano-Hydroxyapatite toothpaste provides gentle cleaning without being abrasive to the enamel. It effectively removes surface stains and plaque, which can contribute to tooth sensitivity. By maintaining a clean and plaque-free tooth surface, nano-hydroxyapatite helps reduce sensitivity and improve overall oral health.
  5. Fluoride-Free Option: Some individuals with tooth sensitivity may prefer fluoride-free oral care products. Nano-hydroxyapatite toothpaste offers an alternative that provides similar benefits to fluoride in terms of remineralization and enamel strengthening, making it suitable for those seeking fluoride-free options.

By incorporating nano-hydroxyapatite toothpaste into their oral care routine, individuals with sensitive teeth can experience relief from discomfort. The protective layer, remineralization properties, enamel strengthening effect, and gentle cleaning action of nano-hydroxyapatite all contribute to reducing tooth sensitivity and promoting oral well-being.
