Does hismile damage your enamel

A whitening kit’s effect on enamel depends on its ingredients, concentration, contact time, application, and the condition of the teeth.

Whitening products use peroxide or other ingredients to alter stain molecules, while enamel itself is not a living tissue that regrows. Irritation and sensitivity can result when product contacts gums, dentine, cracks, or exposed roots.

Read the ingredient and use instructions, keep gel off the gums, and do not extend contact time or combine whitening products. A dentist can check decay, erosion, restorations, cracks, and the source of discolouration first.

Stop and seek dental advice for persistent pain, marked sensitivity, gum burns, uneven colour, or a tooth that changes colour alone. Do not whiten over untreated decay, leaking fillings, or unexplained tooth pain.

Ask which ingredient and concentration the product contains, whether your enamel and gums are suitable, and whether fillings or crowns will change colour. Ask how to manage sensitivity and whether another option fits your staining.
