The gum shield used for my whitening became dull is it okay to use it again?
Q. Hello i wounder if you could give me some advice about teeth whitening, i had my teeth whitened in thailand with zoom whitening and was giving opalescence 20% to use in gum shield which were made specialy for me during the night from time to time when they become dull (not as white as usual) Is it okay for me to do this and will it damage my teeth? thank you
A. No it should be fine, I would check however to see if the product you are using is genuine. Take it in to your local dentist next time you go just to check its fine. If it is you can use it no problem and top up the colour when it starts to fade back a little. Whitening is safe -If you have your annual checkups and your dentist gives you the all clear.
