How does whitening toothpaste work?

Toothpaste that are formulated for reducing the superficial yellowing of teeth contains hard powders that work by polishing the enamel without an excessively aggressive abrasive effect. This gentle polishing removes superficial stains and leaves the enamel shinier which, by reflecting the light, makes the teeth look even whiter.
These toothpastes don't work deep down, and they don't have a permanent effect. However, regular use prevents the accumulation of substances that cause staining and, in the long term, can maintain natural whiteness or the effects of having the teeth whitened at the dentist.

What ingredients reduce surface discolouration?

The hard powders contained in whitening toothpastes and whitening pastes may be sodium bicarbonate (particularly in micro pulverised form), calcium, silica or peroxides (as used by the dentist). However, only extremely low peroxide concentrations are permitted.

Should I choose whitening toothpastes or treatment?

It is important to distinguish between whitening toothpastes and whitening treatments. The toothpastes are intended for daily use, three times a day. While the treatments are products that should be used sparingly, generally twice a week, instead of the toothpaste. The ELGYDIUM WHITENING range includes a toothpaste for everyday use, as well as a whitening treatment to be used twice a week. If in doubt, ask your pharmacist or dentist for advice.
