My wife and I Had a couples teeth whitening. Great deal. Especially l if you bring a friend compared to what my dentist wants to charge. I was super impressed. My teeth are 8 shades whiter and I am going back again to get them just perfect. My teeth are sensitive and I was really uncomfortable after for about 10 hours but it was worth it. Get the desensitizing gel they offer you. It's worth it. Put it on every our after your done to help with sensitivity. I'll be taking some IB profin before as well. Eat a good meal too prior to going cuz you want to stain your new awesome teeth right after. Super happy with the results. Super professional, clean, friendly service as well. Bring your music headphones but not a book. Cant read while whitening. But there is a massage chair! Thank you for the great service!
