Iran-Made Nano-Based Toothpaste Fights Decay, Sensitivity

This product which uses carbonated magnesium hydroxyapatite nanorods in its formula, not only fights tooth decay, but also helps reduce pain caused by tooth sensitivity.

To combat these problems, ‘Merident’ nano toothpaste uses an innovative combination of carbonated magnesium hydroxyapatite nanorods. Hydroxyapatite is a mineral and biocompatible substance that is naturally found in the structure of tooth enamel and bones. By engineering this material at the nanoscale, it can be used as an effective agent for repairing the damaged enamel surface.

The new toothpaste developed based on nanotechnology enjoys several advantages including, gradual restoration of tooth enamel by filling micro-damages with mineral nanorods, reduction of tooth sensitivity due to insulation of tooth nerve pathways, anti-plaque and anti-inflammatory effect to prevent gum disease, teeth whitening while preserving natural enamel, and freshening the mouth and increasing the feeling of freshness after use.

In a relevant development in 2024, Iranian researchers at a knowledge-based company had also succeeded in producing and commercializing a dental composite which contains nanoparticles and is used to prevent tooth decay, specially in children.

“The product of our company is a dental composite in which nanoparticles are used. This composite also fills the groove of the tooth and due to the application of nanoparticles, it also helps to improve the strength of the tooth by releasing phosphate and calcium,” said Mohammad Mo’azzen, the chairman of the board of directors of the knowledge-based ‘Pishgaman Salamat Exir’ company.

Noting that tooth grooves, specially in children, are one of the vulnerable areas which are prone to decay, he said, “Of course, adults also have these grooves, but the depth of the grooves is bigger in children.”

“Resin materials only cover the surface of the groove, but these composites also penetrate deep into the groove and fill it. If these grooves are not filled, there is a possibility of food getting stuck in these grooves and tooth decay,” Mo’azzen said.

“At present, the production line of this dental composite has been launched and we produce approximately 10,000 syringes per year, and this product has been sold in the domestic market,” he stated.
