Please advise me! My teeth are healthy but looking pretty yellow- I had them whitened with a groupon deal around 6 years ago which looked good but they've gradually become more stained (annoyingly I can't remember the actual stuff they used but was around £200)
Do I have to pay loads for teeth whitening? The internet is completely saturated with home use strips, polishes etc, but I just want something that is going to work well and quickly! Also- is it true that any proper whitening needs to be done by a dentist?
There is a BUPA dentist near me that offers zoom whitening- you have to pay £30 first for a check up and then the actual procedure costs £420 for in chair whitening.
Is it necessary to pay so much?
Thanks xx
