I have been given polanight teeth whitening gel and home whitening trays by my dentist to whiten my teeth and I usually wear the trays all night and over the last couple of days, I have noticed that my teeth have become very sensitive during the day.
I cant drink cold water or drinks anymore as I get these shooting pains that are at times very severe. I would like to carry on with my whitening but I am worried that my teeth will become even more sensitive and really hurt when I eat and drink.
Could you advise me, on what I should do to make my teeth less sensitive and painful. Do I need to change my whitening gel? Do I need new whitening trays? please help.
