If you're searching for the best whitening treatment for sensitive teeth, you definitely need to consider only kits with customizable trays. Personalization is important for a number of reasons. First of all, it leads to a more satisfying overall experience, allowing you to fall asleep without any disturbances as your whitening product works its magic overnight. But it's not all about customization alone. CustMbite's Teeth Whitening Kit features trays constructed from patented Vistamaxx material, making these soft frames flexible and lightweight for a truly “barely-there” feel. Customizable trays also help protect your sensitive teeth. In fact, many people choose to wear custom nightguards to preserve the enamel of their sensitive teeth – even if they're not currently going through the whitening process. This means that your customizable trays may come in handy even after you've established that perfect smile you've been dreaming of.
