Our 3 key ingredients

We’ve combined the effects of PAP, Hydroxyapatite, and Potassium Nitrate to whiten and strengthen teeth, without pain or sensitivity.

Phthalimidoperoxycaproic acid (PAP) is a safer alternative to traditional whitening ingredients and the active whitening agent in the HiSmile formula.

PAP has been proven to effectively whiten without causing any damage to the tooth's internal or external structure.
Hydroxyapatite is a naturally occurring mineral in all teeth and is responsible for protecting from harmful factors.

A synthetic version has been included in the whitening formula to replace any previously lost minerals from the tooth surface. This strengthens the protective layer of enamel and allows it to better protect the tooth's inner layers.
Potassium Nitrate is a soothing ingredient, included in the HiSmile formula to desensitise the nerves within the tooth.

It effectively protects against external stimuli, and works to prevent pain or sensitivity from occurring.
