How much are crest 3d white strips

The price of whitening strips varies by pack, seller, formulation, and availability; compare the product details rather than pack size alone.

These products are thin carriers coated with peroxide gel, sold in different strengths, pack sizes, and wear schedules. The relevant comparison is the active ingredient, number of applications, expiry information, seller conditions, and whether the product is intended for natural teeth.

Check the sealed packaging, ingredient list, instructions, expiry date, and seller identity before buying. Do not use strips over untreated decay, broken enamel, exposed root surfaces, or inflamed gums without dental advice, because the gel may worsen discomfort.

Seek dental assessment for a single dark tooth, pain, a fractured tooth, or staining that does not respond as expected, since internal discoloration may need restorative treatment. Contact a dentist if sensitivity or gum burning continues after the product is stopped.

Ask whether the shade is caused by surface stain, enamel colour, trauma, decay, or a restoration, and whether strips are suitable. Ask how to protect exposed dentine and how any existing crowns or fillings will affect the final shade.
