Most sensitivity from whitening comes from two things: gel sitting on the gums, and a formula left on far longer than it needs to be.
What we do differently
In the treatment room the gums are isolated before anything is applied, the gel strength is matched to your teeth, and the light-activated session is timed rather than left to run. That is why a single 45-minute appointment can lift several shades without the ache that strips often leave behind.
Keeping the result
Coffee, tea, red wine and tomato-based sauces are the usual culprits in the first 48 hours, when enamel is most porous. Avoiding them during that window does more for the result than anything else you can do at home.
