Yes! But before you try to use an at-home whitening kit, talk to your dentist about your options. Having your teeth whitened by a professional will always get you better, faster results while keeping your dental history in mind to ensure your comfort and safety. Another benefit of going to the dentist for this procedure is that they will create trays that are custom-fit to the shape of your teeth. Some dentists even use tooth bleaching products that contain hydrogen peroxide in conjunction with a light or laser, which can help accelerate the whitening process.
Many dentists will recommend having your teeth cleaned properly prior to undergoing a teeth whitening session. This makes sense as you would never wax your car with a shine without first giving it a wash (ie., cleaning).
At-home kits often use carbamide peroxide as the bleaching agent, which can cause tooth sensitivity and even leave them more vulnerable to future stains. According to the American Dental Association, those who have yellowish (as opposed to brownish or greyish) teeth are likely to get the best results. You may want to consider teeth whitening if your teeth are stained from red wine, coffee, soda, or tobacco use.
