FAQ
About the kit.
How long until I see a difference?+
The kit lifts stains gradually, so most people notice a change over the full routine rather than overnight. How much depends on how stained your teeth are to begin with.
What does the LED actually do?+
It times your 10 minutes and holds the gel in place, hands free. The gel does the work. The light makes the routine easy to stick to.
Will it change my natural tooth colour?+
No. It lifts surface stains from coffee, tea and wine. Your natural shade stays your natural shade.
Does it work on crowns, veneers or fillings?+
No. It only works on natural teeth. Dental work stays the same shade.
Will it make my teeth sensitive?+
It's peroxide-free and made with sensitive teeth in mind. Everyone is different, so stop and check with your dentist if you feel discomfort.
Who shouldn't use it?+
Anyone under 16, anyone pregnant or breastfeeding, and anyone with sore or irritated gums.

It works!
Despite reading all of the other positive reviews there was still a part of me that wondered if it would make my teeth more sensitive. Happy to say it is super effective and has not made my teeth sensitive at all.

Super product & super company to deal with
My order arrived swiftly and I found the kit easy to use and started to notice results within a few days. Then the unit stopped charging. I emailed lacellora and they responded in hours and put a replacement unit . Good results and excellent customer service!

Whiter brighter teeth
After two weeks of using lacellora my teeth are white again. I had stubborn yellow stains which affected all of my teeth, which was embarrassing and starting to affect my smile. It was easy to use, im ver pleased and will continue to use it. Maintenance is easy. Highly recommend.
