Stephanie Dumanian, D.D.S is a cosmetic dentist and the owner of Park Lex 60 Dental—the go-to for stylish New Yorkers like Busy Philipps, Emily in Paris’ Ashley Park, and celebrity stylist Micaela Erlanger. Park Lex 60 Dental is composed of an all-women team. Dr. Dumanian originally experienced the transformative power of dentistry at a very young age when a dentist, who thought outside of the box, restored her smile by correcting a dental trauma (a congenital missing tooth). The self-confidence which resulted from this treatment changed her life and inspired her to help others. But before we jump into this list of dentist-approved products, let's get a brief overview of what exactly teeth whitening kits are and how they work. Cosmetic dentist Dr. Stephanie Dumanian spells it out simply , “Whitening kits are an easy way to help remove surface stains off your teeth. But they're also a good way of boosting previous whitening treatments you might have had and therefore, maintaining those results." Teeth naturally become more yellow as the years pass. So, perhaps unsurprisingly, you’ll find teeth whitening kits all over the place. If you’re want to invest in a kit that will give you a naturally white smile at the right price without too many unwanted side effects, read our guide below. Teeth whitening isn't permanent. It can last from a few months to up to 3 years – it varies from person to person. Teeth whitening is a form of dentistry and should only be carried out by a dentist or another regulated dental professional, such as a dental hygienist or dental therapist, on the prescription of a dentist.
You can also buy DIY home teeth whitening kits but these may also carry risks. What happens during teeth whitening?
The verdict: Teeth whitening kits
We spoke to Dr Ahmed Hussain, Principle Dentist at Harrow on the Hill Dental Practice about the best teeth whitening tips: What you eat and drink and whether you smoke also contribute to the longevity of teeth whitening effects. "If you’re meticulous at avoiding anything that will stain teeth and upkeep with whitening touch-up products, results will last longer," she explains. "Some of the most teeth-staining foods and drinks are tea (which actually stains more than coffee!), tobacco and red wine, then dark foods and juices like turmeric, beets, curry and blueberries."
Your dentist will advise you whether whitening is right for you. It may be that teeth whitening isn't suitable, for example if you have gum disease or crowns. 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. 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: verifyErrors }}{{ message }}{{ /verifyErrors }}{{ You will then take home your individualised whitening trays, which will allow for up to two weeks of top ups at home.
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. Some home kits don't contain enough whitening product to be effective. Also, if a dental professional isn't doing the whitening, the mouthguard provided may not fit properly so some of the bleaching gel may leak out onto your gums and into your mouth, causing blistering and sensitivity. You may also want to ask them whether there are any risks involved – for example, increasing the sensitivity of your teeth. If you are not happy with the results, speak to the dental professional who carried out your treatment to ask for advice.Try to talk to other people who've had the same treatment or visit another dentist for a second opinion until you feel confident. Always ask for a written treatment plan and price estimate before going ahead. Is teeth whitening permanent? While there are plenty of duds out there, there are still some home DIY kits that will do a very good job helping you feel more confident smiling, without the need for a celeb budget. If you decide to get your teeth whitened, during the procedure at your chosen dental clinic you can expect the following to occur:
Sensitivity-friendly ingredients: If you have sensitive teeth, "carbamide peroxide is less sensitizing than hydrogen peroxide because it takes more time for the whitening action to occur," Dr. Huang explains. 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. Genetics, the environment, lifestyle, diet and ageing can all make teeth look yellow and darker. The most common reason for yellow teeth are surface stains on your enamel, which are usually caused by what we eat and drink, or if we smoke. The dentist will take an impression of your teeth to make a mouthguard and tell you how to use it with a bleaching gel. Then, using your mouthguard at home, you regularly apply the gel for a specified period of time over a few weeks. Some whitening gels can be left on for up to 8 hours at a time, which can shorten the treatment period. At the start of an in-clinic whitening treatment, your dentist will take a mould of your teeth, using either putty impressions or a 3D digital scanner. This mould will be used to create a set of custom plastic trays for your teeth, which will fit over your teeth perfectly. These will be given to you to use at home with specially prescribed tooth whitening gel.
