Common questions
How long until I see results?
Many people notice a change within a week or two of regular use.
Why custom trays over shop kits?
Custom trays fit closely, spread the gel evenly and help keep it off your gums.
Is it normal to feel sensitivity?
Yes. Mild sensitivity is common and usually eases with a break or a gentler routine.
Can I keep my trays for later?
Yes. As long as they still fit well, you can top up with more gel down the track.
