Is plus white safe for your teeth

The risks of an at-home whitening product depend on its peroxide ingredients, concentration, contact time, fit, and the condition of your teeth and gums.

Whitening products use peroxide chemistry to break down coloured molecules in enamel and dentin. A product may not change the colour of fillings, crowns, veneers, or other tooth-coloured restorations, so the result can be uneven.

Read the ingredient and use instructions, keep gel off the gums, and stop if you develop significant pain, gum irritation, or persistent sensitivity. A dentist can check for cavities, cracks, gum recession, and existing restorations before recommending a whitening method.

Arrange an examination before whitening if you have untreated decay, gum disease, enamel defects, exposed roots, or unexplained sensitivity. Seek care for severe pain, ulceration, facial swelling, or a reaction that does not settle after stopping the product.

Ask what the product contains, whether your enamel and gums are suitable, and whether restorations will match afterward. Ask about a controlled tray or in-office alternative if sensitivity is a concern.
