This company are promoting teeth whitening through Groupon vouchers.

I naively bought a voucher.

You are not able to ring them direct, you can only e-mail.
They are not trained professionally
They use Chlorine Dioxide, which is deemed as illegal by most dentists and governing boards, who I have spoken to.
I was left sneezing, a sore throat and a cough after the treatment for 24 hours
My gums started receding
Teeth and gums painful
Had to pay double the money to go to an emergency dentist to get treatment.

I have been told that my teeth will probably always be sensitive now, will colour easily and gums will not grow back.

I complete scam!

When you try to complain, the manager does not speak to you but tells someone to tell me to put vitamin e on my gums.

DO NOT USE!!!!!

Pay more money for the best treatment!!
