Hydroxyapatite: the good and the wonderful

Oral care innovators are always on the lookout for new natural ingredients that can help protect our teeth, whether from bacteria, stains or loss of enamel.

In terms of the latter, the most common practice is to add sufficient level of Fluoride – a naturally occurring mineral, which prevents tooth decay keeping enamel strong – to either water supply or various oral care products. However, considering that the effectiveness of Fluoride depends on concertation as well as the fact that high levels of Fluoride above the commonly recommended dose of 1450 ppmF can be toxic, especially for children due to the risk of Fluorosis that leads to discoloration of permanent teeth, there might be a time now to explore natural alternatives to Fluoride, such as Hydroxyapatite or HA featured in our newest Deeno range of toothpastes specifically designed for children.

Hydroxyapatite is natural

Using ingredients of natural origins has become increasingly important in children products seeking to ensure safety. Good news is that HA, in the form of calcium apatite crystals, is naturally present in human bones, teeth and particularly enamel, thus making it an integral part of our body. HA has been widely used by medical and dental profession to restore bone structure, as it is composed of calcium and phosphate, and has no toxic effect on human body.

Hydroxyapatite helps to restore enamel

Extensive research, which compared the effectiveness of HA and Fluoride, has confirmed that HA has an ability to be absorbed into tooth surface filling out micro-lesions. Furthermore, it helps to naturally increase concentration of calcium and phosphate in saliva, both of which are necessary to keep enamel strong and healthy, as a result promoting effective remineralization of enamel without any toxic effect from potential overexposure, like in case of Fluoride.

Hydroxyapatite helps to reduce teeth sensitivity

Tooth sensitivity or a painful discomfort in response to hot and cold food and drinks is typically caused by worn enamel that exposes inner layers or roots of your teeth. Considering that HA helps to restore micro-lesions effectively rebuilding the enamel and covering the exposed parts, it might also lead to diminishing sensitivity.

Hydroxyapatite helps to keep dental plaque away

When a layer of loose bacteria accumulates on the surface of your teeth and around gums it is commonly called a biofilm or dental plaque, which, once hard enough, can develop into tartar and become a leading cause of both tooth decay and gum disease. Therefore, ensuring proper removal of plaque is an important part of good dental hygiene. Interestingly enough, recent research has shown that apart from strengthening the enamel HA has the ability to be absorbed into the various bacteria binding them together, which disrupts the biofilm and makes the removal of plaque easier and more efficient.

Seeking to deliver safest protection for children, DEENO brand offers two versions of Hydroxyapatite toothpaste.

The Deeno-Saur Natural Toothpaste with Fluoride is suitable for children over 3 years old, while the Deeno-Saur Natural Toothpaste without Fluoride can be used from the very first tooth. Combined with absence of SLS, preservatives as well as artificial flavours, colours and sweeteners, both toothpastes offer all the benefits of Hydroxyapatite to protect those little teeth in the most natural way.
