The questions we get most often
No. The sharp twinges people associate with whitening come from hydrogen peroxide, and Mr. Fris doesn't contain any. You'll feel the tray in your mouth, nothing more. Does it still feel unpleasant during those 60 to 90 minutes? Take the tray out and brush your teeth; you can simply try again the next day.
You'll often see a difference after 1 or 2 treatments. You can judge each day whether you're happy and stop as soon as you like the result.
A top-up once every 1 to 2 months is enough to maintain your result. How quickly your teeth discolour again depends on what passes them: coffee, tea, red wine and smoking are the usual culprits.
No. Whitening products that can damage enamel do so through hydrogen peroxide in high concentrations. Mr. Fris works with Phthalimidoperoxycaproic Acid: it breaks down discolouration without touching the enamel itself.
Use one tray a day. You can stop as soon as you're happy with the result, usually after 1 to 2 times.
No worries. You can try Mr. Fris risk-free for 30 days. All we ask: take a dated before photo and after photo of your teeth. No result? Then you simply get your money back.
