Some whitening toothpastes also contain low levels of hydrogen or carbamide peroxide, which, as noted above, brighten your smile too.

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. However, it’s important to choose a toothpaste with the appropriate amount of abrasives. A toothpaste with a higher abrasivity could damage your enamel with long-term use. While this is a tradeoff for less abrasivity and a greater chance of developing stains, the removal of an enamel to expose the inner layer of dentin would cause more harm. Therefore, we recommend that you look for a stain removing toothpaste with the ADA Seal of Acceptance. If you choose a toothpaste without the ADA Seal of Acceptance, consult your dentist as to how often you should use it. 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.
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. Hydrogen peroxide is a very effective bleaching agent, but can irritate gums and aggravate sensitivity in the teeth. These whitening strips, which lighten teeth by up to six shades, are peroxide-free, so are especially suitable for sensitive teeth. The strips mould to teeth well and are pleasant and comfortable to use. Results are a little less noticeable than with a peroxide formula, but still noticeable after two weeks. If you prefer to avoid peroxide, these strips offer a safe and effective alternative – and they’re suitable for vegans, too. Research shows using baking soda (sodium bicarbonate) can improve the appearance of your teeth. Since it’s an alkaline compound, it works to reduce stains and get rid of bad bacteria.

Brush and floss as normal after bleaching. A whitening toothpaste will help keep surface stains at bay once you’ve achieved your desired level of whiteness. Look for products containing gentle natural abrasives such as bicarbonate of soda or charcoal, which can’t penetrate the enamel of the tooth in the way that bleach in your whitening product does, but can be very useful after bleaching to help maintain whiteness. 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.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.” There are plenty of options to choose from when considering what at-home whitening product is right for you. Narrowing down your budget, desired length of treatment and whitening goals will help you choose. Speak with your dental professional about what OTC products they would recommend given your unique oral health. Teeth Whitening Kits The best teeth whitening strips you can buy in 2023 1. Spotlight Oral Care Whitening Strips: Best teeth whitening strips overall For safety reasons, in the UK, at-home teeth whitening kits may contain hydrogen peroxide at concentrations at up to 0.1%, whereas your dentist, using a custom-fitted mould, is able to safely use a concentration of up to 6% without harming teeth or gums. This means the professional treatment is usually able to achieve more noticeable lightening results. Dentist-only treatments such as laser whitening (in which the bleach solution is activated by a laser shone onto teeth) are also much faster, taking only 1-2 hours. The strength of the application also plays a role in how long you need to apply a treatment. Usually, the higher potency of a bleaching agent can initially boost whitening. But this can be a double-edged sword, as a higher percentage of whitening chemicals puts you at greater risk of sensitivity and inflammation.
