Hismile purple toothpaste before and after

Purple toothpaste can temporarily alter the visual contrast of yellow tones, but it does not permanently bleach the internal colour of teeth.

The short answer

Purple pigments sit on or near the tooth surface and can create an optical colour correction after brushing. The effect is temporary because saliva, food, and brushing remove the pigment; it is different from peroxide whitening, which changes some stain molecules.

What is the direct answer?

What does this question mean?

Use the product as directed, spit thoroughly, and avoid swallowing it. For a lasting shade change, a dentist should identify whether the colour comes from surface stain, enamel, dentine, medication, trauma, or a restoration before choosing cleaning or whitening.

What can you do next?

Seek assessment for a single grey or brown tooth, sudden colour change, pain, or a stain that does not respond to cleaning. Stop using the product if it irritates the mouth or worsens sensitivity.

When should you seek dental care?

Ask whether your colour is surface stain or intrinsic discolouration, whether peroxide whitening is suitable, and how existing fillings, crowns, or veneers will compare afterward.
