My friend went for it doing and then chickened out as it was quite a long drawn out process (for her anyway). She opted for the bleaching, where a gum shield thingy? is used. Catagay supplied enough for about 6 sessions which are used at home. However it became very painful to use after 2 sessions as it made her gums sore. Her teeth looked whiter but we read on the internet that after " a certain age" it is better not to use this method as the gums may have receded a bit. Also after bleaching do not drink red wine, smoke etc. as the teeth become porous. Cost for lazer was going to be £400. bleaching was £200. I seem to remember. This was June this year.
