I am using PolaNight teeth whitening (the 16% one) which my dentist gave me, i am meant to be doing it for two weeks.
I have done it for two nights, and I was about to do it for the third when I noticed in the mirror that on one of my bottom teeth the gum has receded so much I can see the root of the tooth. Before i began the treatment the gum of this tooth had not receded at all in the slightest. I have not done the treatment since I noticed the receding.
Could the gum receding be linked to doing the teeth whitening? I want to continue with the whitening, being very cautious of this tooth in the process, but I am a little petrified to continue with it incase it is the Polanight making my gum recede and it does it to any of my other teeth's gums.
