Because the pen serves two purposes, it comes with two sets of instructions. If you’re using the pen primarily as a stain repellent—especially before that cup of coffee or glass of red wine—just apply two coats to your teeth and wait 60 seconds before eating or drinking. If you’re looking for whitening results, follow the same directions but wait 30 minutes before you eat or drink. You should see results after one application.

Active ingredients: For optimal teeth whitening results at home, "look for the active lightening ingredients hydrogen or carbamide peroxide," advises Sharon Huang, D.D.S., MICOI, a cosmetic dentist and founder of Les Belles NYC in New York City. Note that although hydrogen peroxide produces excellent whitening effects, it can sometimes result in temporary tooth sensitivity, Dr. Gonchar says.

For extremely sensitive teeth, there are also products that don’t contain peroxide, and instead are made with ingredients like aloe vera and coconut oil, which have natural whitening effects that pull stains from the teeth, she says. "They're not as effective as peroxide, but are a good natural option that’s gentler on the teeth," Dr. Huang notes.

When a product was found to have too much, we retested it in the same way.For any products that come with a gel formula, it's worth getting a custom-made mouth tray that's tailored to your teeth and mouth. This will prevent any of the formula from leaking out on to your gums and will minimise the risk of swallowing or gum damage. Mould-your-own trays are available online, or this can be done at a dentist.' The method: This off-the-counter option is a budget hero that delivers results over time, but most importantly cares for your dental hygiene. The way toothpastes and mouthwashes work to brighten your smile is by employing polishers and abrasives that will remove surface stains and lighten discolouration (like dark spots), combined with gentle chemical bleaching agents to whiten. The new Colgate Max White Expert Complete Whitening Toothpaste, also contains 'optic brighteners', which reflect blue light to make your teeth look instantly whiter. Kind of like how purple toning shampoo eliminates brassy tones and brightens blonde hair. There are four main types of at-home teeth whitenining products: whitening strips and trays, LED light devices, pens or gels and toothpastes. "The effectiveness of at-home teeth whitening products can vary from person to person, and what works best for one individual may not yield the same results for another," Dr. Katz notes. Here's a guide to what differentiates each of the options and how they function so you can choose the right form for you, according to the dental experts: At-home teeth whitening kits are a more accessible alternative to professional whitening treatments, which can deliver instant and more dramatic results but at a higher price. DIY teeth whiteners can include whitening strips, trays, gels, pens, toothpastes, mouthwashes and LED lights as accelerators, which can provide noticeable effects both immediately and with use over time. "They use various chemical or abrasive agents to lighten or remove stains on your teeth to make them appear whiter," explains Marina Gonchar, DMD, orthodontist and owner of Skin to Smile in Morristown, New Jersey.
