I had sensitive teeths. I consulted doctor and he suggested me Ultraez. UltraEZ quickly eliminates sensitivity from tooth whitening, thermal and chemical changes, root exposure, and toothbrush abrasion. I had a whitening treatment and my teeths became more sensitive after that. I used Ultraez and it cured sensitivity in 10 days. Apart from sensitivity relief it cleans teeths to perfection. Mint flavour also reduces mouth odour. Really an amazing gel. Must have for people with sensitive teeths.
