I’ve only had my immediates since August. I’ve tried every single sample adhesive and paste I was given or sent after requested. They were horrible and I was really getting discouraged till I received Dr.B’s samples. This stuff is AMAZING! No taste at all. It’s so easy to apply and clean off . I ♡ that I can brush my gums and dentures with the same paste! I stopped getting sore spots with the adhesive and the cleaning paste. Plus the liquid crystals are amazing too! I smoke and drink coffee so I’m particularly worried about stains and since I started using this line they always look brand new! Thanks Dr. B! I’m now a life time customer!
