To Rebecca,

We hear of this daily where dentists overcharge the patient,so your
not alone  :-(  ..

If you feel that you not got what you have paid for then speak or
write to your dentist and tell them how you feel .. Laser teeth
whitening at the dentist can be very expensive and it is not as
effective as using a professional home tray system, your better
bleaching your teeth at home as you can whiten your teeth when you
want and do not need to see the dentist and pay out a fortune in
dental  charges.

Visit happysmileuk.com or polanight.co.uk for details on professional
home teeth whitening systems the same the dentist sells...

I am sure you will get better teeth whitening results using a home
tray system,  ( www.happysmileuk.com teeth whitening) have some great
teeth whitening products.

The colgate 9% visible white is very popular and can make a dramatic
difference in tooth colour, for only 34.99.

Also  polanight.co.uk the same brand of dental bleach as the dentist,
prices from ONLY 34.99, you would pay over £400 for polanight from the
dentist !!  Buy online its much cheaper !!  visit teeth whitening
