The blue one is for the upper teeth, and the silver one is for the lower teeth. Use it once in the morning and evening, for 30 minutes each time. Apply it after brushing your teeth for a while, and avoid applying it right after brushing your teeth. The design of Crest tooth stickers is rectangular for the upper teeth, and the lower teeth stickers are shorter, about half the size of the upper ones.

Do I need to brush my teeth after using Crest whitening strips?

You don't usually need to brush your teeth after using Crest whitening strips, but you must rinse your mouth in time. The whitening effect of using Crest whitening strips is not particularly obvious. If you want to completely improve the yellow teeth, you can use ultrasonic teeth cleaning. Ultrasonic teeth cleaning can effectively remove plaque and calculus on the teeth, restoring the teeth to a bright and white effect.

Does Crest whitening strips have any side effects on teeth?

The principle of tooth stickers is to use the oxygen atoms released by hydrogen peroxide cross-linking to interact with the pigments deposited on the surface and deep layers of the teeth, absorb the pigments and deposit them inside the teeth, reduce tooth discoloration, and achieve the effect of whitening teeth.

Whitening strips use low-concentration hydrogen peroxide to bleach teeth. If used correctly, they will not harm teeth in the short term, but long-term use may cause tooth soreness, pain, sensitivity, and even infection. If used for a long time, it will destroy the enamel structure and make the tooth surface rough. In short, it will cause tooth damage.

Whitening stickers can discolor teeth and brighten yellow teeth. However, hydrogen peroxide can irritate the gums and oral soft tissues, and may also irritate the marginal nerves and blood vessels of the gums, causing allergies such as sourness, fear of cold, and even infection. If long-term use leads to excessive levels of hydrogen peroxide in the mouth, the stimulation of the nerve tissue of the teeth can cause toothache and may affect normal diet and sleep.

What is tooth paste

Dental veneers include resin veneers and all-ceramic veneers, which are bonded to the labial and buccal sides of teeth to change the color of the tooth and restore its appearance. Resin veneers can be made directly in the mouth, using a diamond grinding needle to remove a small amount of tooth tissue, disinfecting with alcohol, drying, using 30% phosphoric acid to etch the enamel surface, and after thorough rinsing, applying adhesive, depositing composite resin on the labial surface, trimming the shape, and curing with light. Tooth preparation can also be performed, impressions made, and resin cement used to bond the prepared all-ceramic veneer to the labial side of the tooth, and removing excess adhesive.
