Calcium Hydroxyapatite and Your Teeth

Is hydroxyapatite good for your teeth?

Hydroxyapatite is purported to be good for teeth, indeed.

This naturally occurring mineral, a major component of tooth enamel and dentin, plays a vital role in maintaining dental health. We'll dive into more detail within this article, but here is a summation of a few calcium hydroxyapatite core benefits:

- Hydroxyapatite helps remineralize tooth enamel, making it stronger and more resistant to decay, while also repairing minor enamel damage.

- It can reduce tooth sensitivity by sealing dentinal tubules, which block the transmission of pain signals.

- Additionally, its anti-cavity properties have led to its inclusion in some toothpaste formulations. Being biocompatible with the human body, hydroxyapatite is safe for use in dental applications, making it a valuable asset for promoting dental health.

Can calcium hydroxyapatite remineralize teeth?

Calcium hydroxyapatite can potentially contribute to the remineralization of teeth. Hydroxyapatite is a naturally occurring mineral and a major component of tooth enamel and dentin. It is a form of calcium phosphate, and when it comes into contact with your teeth, it can help restore lost minerals to the enamel, making it stronger and more resistant to decay. This process is often referred to as remineralization.

In oral care products, like toothpaste and mouthwash, calcium hydroxyapatite is sometimes used because of its remineralization properties. When these products are used, they can provide a source of calcium and phosphate ions to support the remineralization process.

However, the effectiveness of calcium hydroxyapatite in remineralizing teeth can vary depending on the specific product and how well it is used. We'll talk about vetting products for quality within this article, toward the end. Read on!

What are the disadvantages of hydroxyapatite?

In the context of oral care products, hydroxyapatite has gained popularity as an ingredient in toothpaste, mouthwash, and other dental products. However, there are a few potential disadvantages associated with its use in this application:


Hydroxyapatite, when used in high concentrations in toothpaste, can be abrasive to tooth enamel. While it's intended to help with remineralization, excessive abrasiveness can lead to enamel wear over time. Manufacturers typically balance the abrasiveness of hydroxyapatite-containing toothpaste with other ingredients to ensure they do not damage the teeth.


Toothpaste and dental products containing hydroxyapatite can be more expensive than conventional alternatives. This cost factor may be a drawback for some consumers, as it can make oral care products less accessible to those on a budget.

Efficacy Variability

The effectiveness of hydroxyapatite-containing oral care products can vary between brands and formulations. Not all products may provide the same level of remineralization or sensitivity relief, so it's essential to choose reputable products. As mentioned earlier, we'll talk on how to discern a quality product with calcium hydroxyapatite within this article.

Taste and Texture

Some people may find the taste or texture of hydroxyapatite-containing toothpaste to be different from what they are accustomed to. Personal preferences and sensitivities can influence the overall experience.

Limited Clinical Evidence

While hydroxyapatite shows promise in remineralizing teeth and reducing sensitivity, the long-term clinical evidence supporting its benefits is still evolving. More research is needed to establish its effectiveness conclusively.

Despite these potential disadvantages, many people find hydroxyapatite-containing oral care products to be a valuable addition to their dental care routines; hereon out, we'll touch on the benefits of calcium hydroxyapatite.

How do you use calcium hydroxyapatite on your teeth?

You can use calcium hydroxyapatite on your teeth through oral care products like toothpaste and mouthwash that contain this ingredient.

To get the most out of these products, choose the right one, follow the provided instructions, and be consistent in your usage:

Start by selecting a toothpaste or mouthwash that explicitly lists calcium hydroxyapatite as one of its ingredients.

These products are specially formulated to aid in remineralization and strengthening of tooth enamel. Once you've obtained the appropriate product, read the instructions on the packaging carefully. Different products may have varying recommendations for use, so it's important to understand how to use your chosen product correctly.

When using toothpaste, wet your toothbrush, squeeze a pea-sized amount of the toothpaste onto your brush, and proceed to brush your teeth as you typically would.

Ensure that you cover all surfaces of your teeth, and follow the recommended brushing time, which is usually around two minutes. After brushing, spit out the toothpaste, but do not rinse your mouth immediately. Allowing the active ingredients, including calcium hydroxyapatite, some time to work on your teeth can be beneficial. You can choose to rinse after a few minutes if desired.

For mouthwash, measure the recommended amount of mouthwash using the cap or a measuring cup provided with the product. Rinse your mouth with the mouthwash for the specified duration as indicated on the product label. After rinsing, spit out the mouthwash. It's advisable to avoid eating or drinking for a short period after using it to allow the active ingredients to have an effect.

Consistency is key when using these products, so be sure to incorporate them into your daily oral care routine for the best results.

How long to leave hydroxyapatite on teeth?

The duration for which you should leave hydroxyapatite on your teeth may vary depending on the specific oral care product you are using. In the case of toothpaste containing hydroxyapatite, it is generally recommended to brush your teeth for the recommended amount of time, which typically falls around two minutes.

During this brushing period, the hydroxyapatite and other active ingredients in the toothpaste work to benefit your teeth. After brushing, you should spit out the toothpaste.

Some recommendations suggest not rinsing your mouth immediately after spitting out the toothpaste, as this allows the active ingredients, including hydroxyapatite, more time to interact with your teeth. You can choose to rinse your mouth after a few minutes if you prefer.

If you are using a mouthwash that contains hydroxyapatite, it's essential to follow the usage instructions provided on the product's label. Typically, this involves rinsing your mouth with the mouthwash for the duration specified by the manufacturer.

Following the recommended rinsing time, you should spit out the mouthwash. As with toothpaste, it's often advised to avoid eating or drinking for a brief period after using the mouthwash. This allows the active ingredients, including hydroxyapatite, to work on your teeth more effectively.

Adhere to the specific usage instructions on the product you are using, as different products may have variations in recommended usage times. Consistency in using these products as part of your regular oral care routine is likely more important than the exact duration for which the product is left on your teeth.

Can you reverse cavities with hydroxyapatite?

Hydroxyapatite has the potential to aid in the remineralization of early-stage, non-cavitated dental lesions, sometimes referred to as "white spot lesions" or incipient caries. These are areas of demineralization in the enamel where minerals have been lost but have not progressed to the formation of a cavity or hole in the tooth.

The idea behind using hydroxyapatite is that it can help restore lost minerals to the enamel, making it stronger and more resistant to decay.

However, it's important to understand that this remineralization process is most effective in the very early stages of enamel demineralization and when the tooth structure is not yet significantly compromised.

Once a cavity has formed, where the enamel has been irreversibly damaged and a hole has developed, hydroxyapatite cannot reverse the damage. In such cases, the cavity must be treated by a dentist, usually through techniques like dental fillings or dental crowns to restore the tooth's structure.

To effectively use hydroxyapatite for remineralization, it's typically incorporated into oral care products like toothpaste or mouthwash. Regular use of these products, along with good oral hygiene practices, can help prevent the progression of early-stage dental lesions and maintain healthy teeth. If you suspect you have a cavity or more advanced dental decay, seek professional dental care.
