Crest strips supreme

Whitening strips use peroxide gel on natural enamel; they do not whiten fillings or crowns and can cause tooth sensitivity or gum irritation.

Whitening strips hold a peroxide gel against the front surfaces of teeth. They can change some external and internal enamel discoloration, but they do not whiten fillings, crowns, veneers, or other dental materials, and they do not remove tartar or repair cavities.

Read the product directions, keep gel off the gums, and stop if you develop significant burning, pain, or sensitivity. A dental examination is important before whitening when there are cavities, gum inflammation, cracks, exposed roots, or extensive restorations.

Seek dental care for persistent sensitivity, gum injury, tooth pain, swelling, or a dark single tooth. These signs can indicate a dental problem that whitening will not correct.

Ask whether your discoloration is suitable for peroxide whitening, how existing restorations will look afterward, and whether a supervised option or another treatment better matches your goal.
