Enjoy your Best Smile with Crest Whitening Strips

To enjoy a smile that is free from stains caused by foods or beverages, use Crest whitening strips. Packets on eBay make it easy to whiten your teeth comfortably at home, while providing you with the convenience you need as you travel.

Is bleach used in Crest whitening strips?

Yes. Bleach is used in Crest whitening strips, so proper application is essential at all times. Crest whitening strips are designed to safely remove intrinsic and extrinsic marks, but only when applied as directed. Intrinsic stains are caused by normal aging, tooth trauma or medications and even excessive fluoride use, while extrinsic stains develop over time by exposure to tobacco products, foods and beverages.

Can Crest white strips cause gum discomfort?

Crest whitening strips sometimes cause gum discomfort initially, while some people experience tooth sensitivity because of whitening, but the effects are temporary. If you have sensitive teeth caused by whitening, wait a few days and then complete your next treatment, but if you still notice tooth whitening sensitivity, visit your dental professional. 

People may develop sensitivity and experience discomfort when they have cold or hot foods, after treatment with a product containing peroxide at their dentist, so if your teeth start aching during a professional treatment or while using whitening strips at home, you should stop. There are Crest whitening strips formulated specifically for people who have teeth that are sensitive and these have lower peroxide levels and shorter periods of application. Mild treatments use the same ingredient as stronger strips and provide the following benefits:

  • Crest white strips for people with tooth sensitivity only have six percent hydrogen peroxide.
  • Crest whitening strips for people with sensitive teeth are usually applied for just five minutes.
  • Crest 3D White Whitestrips Gentle Routine provides subtle whitening via a mild formula and may be easier to use if you have sensitive teeth.

Can Crest whitening strips strengthen teeth?

Crest whitening strips have ingredients that help to strengthen teeth while whitening them and they can be safely used with Crest 3D White Luxe Toothpaste, which rebuilds weakened tooth enamel, so 90% of surface stains can be removed in a week, giving you a just-polished feeling, while using enamel-safe ingredients.
