Review on 🦷 Non-Sensitive Teeth Whitening Pen: Effective Gel for Whiter Teeth, Easy-to-Use Kit with 20+ Uses, Painless and Natural Solution, Removes Stains from Smoking, Coffee, Soda by Tammy Chavez

I haven't used many different bleaches. But this is definitely the first time I've tried a brightening light bath. I love coffee and it shows on my teeth even though I brush three times a day and sometimes more. I am impressed with the discoloration of my teeth. The table provided will help you to tell the difference. Although I have sensitive teeth, I was able to use this whitening kit without any problems. In the evenings I fill trays and watch TV and before you know it the timer is up. The tray has a built in 10 minute timer, making it so convenient that you can use it for exactly 30 minutes.
