An impressive smile can go a long way in making a good first impression. However, some people may have stains or discoloration on their teeth either due to genetics or due to drinking tea, coffee, smoking, or chewing tobacco. Fortunately, minor discoloration and stains can be treated with the help of certain OTC at-home teeth whitening solutions. Some of the most popular at-home teeth whitening gel solutions and kits are listed below.

1. Crest 3D Whitestrips
Crest is a trusted brand for dental solutions and the 3D Whitestrips kit offered by them is one of the most popular and easy-to-use solutions in the market right now. The brand claims that users can see visible results by using the kit daily for 20 days. At the end of 20 days, you can notice the color of your teeth turn up to four shades lighter than before. Moreover, the new version of these whitening strips adds a fresh flavor of mint while whitening your teeth, which largely enhances the entire process. One kit comes with a total of 20 whitening strips that contain a whitening gel and can cost around $48.

2. AuraGlow Teeth Whitening Kit
The teeth whitening kit from Auraglow comes fully equipped with an LED light and teeth whitening trays that comfortably fit your top and bottom set of teeth. The whitening solution contains 35 percent carbamide peroxide, which is milder than the standard 40 percent used by most dental offices. Due to the LED light, the process of whitening is extremely quick with these trays and can be completed within 30 minutes. The cost of one such kit is approximately $48.

3. Lumineux Teeth Whitening Strips
If you are looking for non-toxic options to help whiten your teeth and are not too keen on putting hydrogen peroxide or carbamide peroxide into your oral cavity, you should definitely try these teeth whitening strips.

You can get a single kit for approximately $50 online.
