I impulse bought Phillips Zoom tooth whitening on Groupon. £99. I thought it was a good deal as you get the Zoom instant whitening which takes an hour in the dentists chair, then follow up gel whitening.
Reading more about it i’ve heard it can be painful and can cause sensitivity. However, some of these reviews are from ages ago and presumably it’s improved.
Has anyone had any experience? Wondering whether to pull out now and view it as an expensive lesson in not impulse buying!!
