Most teeth whitening products use one of two chemicals—hydrogen peroxide or carbamide peroxide—as the active whitening agent. The oxygen molecules within these chemicals interact with the molecules of your discolored tooth. As the whitening agent molecules infiltrate your teeth, they weaken the bonds of the stained molecules, slowly removing them.

The American Dental Association ensures that with proper use, your enamel will not be weakened or damaged by their approved toothpastes. Some whitening toothpastes also contain low levels of hydrogen or carbamide peroxide, which, as noted above, brighten your smile too.Compliance is often high, however, thanks to pens’ price point (which can be as affordable as just a few dollars per pen) and the simple instruction to apply twice daily for two weeks. Whitening pens typically use either a hydrogen peroxide or carbamide peroxide base. The ADA notes that further research is needed on sensitivity prevention for teeth bleaching. When you speak with your dental professional, be sure to ask about sensitivity as well. Your dentist can recommend any pre or post-whitening remedies that may have worked for their patients in the past. For example, they may recommend a desensitizing agent or a fluoride treatment to strengthen your enamel.

Tooth pain can happen when the peroxide whitening agent reaches your dentin, the layer of tooth under your enamel, which irritates your tooth’s nerves. Sensitivity is typically temporary. Taking a break from teeth whitening until it subsides, then resuming, can help. If used correctly, at-home kits will certainly lighten your teeth by a few shades. You might want to pop to the dentist for at least a thorough dental clean before starting your treatment, as plaque and tartar on the teeth can stop the bleaching agents penetrating stains, so getting everything scrubbed clean first is bound to boost results. What else will help my teeth stay white?

As the bleach used is at a weaker concentration than your dentist can supply, most at-home whitening methods take around two weeks to yield results. Expect results to last for around 12 months. What’s your budget? The cost of at-home whiteners ranges considerably—even within the same product type. But generally, kits and strips cost more than pens and toothpastes. Epple M, Meyer F, Enax J. A Critical Review of Modern Concepts for Teeth Whitening. Dentistry Journal. 2019;7(3):79.Smile Science Harley Street Professional Teeth Whitening Strips: Best teeth whitening strips for sensitive teeth In the old days, people used to sleep with whitening trays in for eight hours at a time,” says Joe G. Willardsen, a cosmetic dentist in Las Vegas. “Now, people wear them for 15 or 20 minutes at a time but do so more frequently.” The strips need to be applied daily for up to 30 minutes. Follow the instructions on your chosen kits carefully, as some strips are designed to work with a shorter developing time. Extrinsic stains, as you may have guessed, are stains that appear on the outside layer of your teeth. If you enjoy drinking coffee, tea, soda, and/or red wine regularly, you likely have more extrinsic stains than someone who drinks mostly water. Eating certain bright-colored foods such as blueberries, beets, curries and tomato-based sauces and using tobacco products also darken teeth. At-home whitening products can be helpful in removing these exterior stains from your teeth. Toothpastes are the exception to peroxide rule. Most toothpastes advertised to whiten teeth don’t contain a whitening agent, but rather abrasives such as silica that mechanically remove stains from the enamel layer of your teeth.
