Will whitening trays damage teeth after continuous use?

Question

Most people bleach their teeth once every six months, but would bleaching teeth more than that cause damage?

Answer 1

DAMAGE TO TEETH= UNLIKELY
DAMAGE TO GUMS IF THE BLEACHING GEL GETS ON THE GUMS = A POSSIBILITY
WILL THIS BE PERMANENT DAMAGE? = NO, JUST IRRITATED.
WHAT WILL DO TO THE TEETH THEMSELVES?
MAKE THEM MORE SENSITIVE TO COLD.
DOING A TOUCH-UP WHITENING IS A NICE IDEA EVERY 6 MONTHS TO KEEP A SMILE LOOKING GREAT.
