Now that you understand what causes whitening-related pain, it's easier to address the situation. First of all, consider switching to a whitening product with a lower concentration of peroxide. CustMbite's Gentle Whitening Foam uses carbamide peroxide at a concentration of just 8%, making it a great solution for sensitive teeth. Not only is it gentler, but it also delivers results faster than many other competing whitening products – including whitestrips. If you choose CustMbite's Gentle Whitening Foam from the very beginning, you can avoid pain later on. Alternatively, you can switch to this product partway through your whitening treatment, ditching your old whitening agent and opting for a more comfortable, stress-free solution. Another tip is to use customized, flexible, and comfortable trays during and after the whitening process. This will help protect your sensitive enamel while you sleep. In addition, it leads to a much more pleasant overall experience, as you won't be dealing with a bulky, oversized chunk of plastic in your mouth. CustMbite's Teeth Whitening Kit features trays made from patented Vistamaxx material for a truly personalized, snug fit.
