Dental Sensitive

How do the hydroxyapatite nanoparticles work to whiten dental enamel?

Irregular tooth enamel or cracked enamel becomes more dull and darker, since light loses its intensity when it hits the tooth surface. The hydroxyapatite nanoparticles fill the irregularities of the tooth enamel, creating a surface that is smoother and brighter, giving teeth back their natural white colour.

How do the hydroxyapatite nanoparticles work to repair sensitive teeth?

Dental sensitivity is caused by a process of gingival recession or by tooth enamel wear. When this occurs, the dentin loses its protective covering and the dentinal tubules are exposed, allowing external stimuli to reach the nerve ends and cause pain.

The hydroxyapatite nanoparticles are deposited on teeth, sealing the open dentinal tubules and blocking the transmission of external stimuli to the pulp, therefore preventing pain.
