Blanx whitening strips before and after

Before-and-after results vary with the original shade, the type of discoloration, gel concentration, fit, wear time, and whether the visible tooth is natural enamel. Crowns, fillings, and veneers do not bleach like enamel. Temporary sensitivity or gum irritation can occur when peroxide contacts dentin, an exposed root, or soft tissue. Uneven color can become more obvious when restorations do not change shade.

Follow the product directions exactly, keep the gel on the teeth rather than the gums, and do not extend the wear time to chase a faster result. Stop if there is significant pain, burning, or persistent gum whitening. Have dark spots, cavities, leaking fillings, cracks, gum recession, or existing restorations checked before whitening. A dentist can identify the stain type and select strips, custom trays, or another method when appropriate.

Obtain a dental examination before whitening if you have tooth pain, untreated decay, gum disease, exposed roots, cracks, or extensive restorations. Seek care for severe sensitivity, a chemical burn, or symptoms that do not settle after stopping.

Ask whether the discoloration is on the surface or inside the tooth and whether every visible tooth is natural enamel. Ask how to protect exposed dentin and how restorations will affect the final shade.
