I had HORRIBLE teeth from years of cigarettes and diet colas and thought I was doomed to yellow teeth forever. Not so! After only two treatments, my teeth are amazing and white!! People are amazed at the difference. Nice atmosphere, professional and friendly. I had the extra strength treatment both times and experienced only a bit of sensitivity the second session, but it was gone by that evening. I recommend Meredith and her staff to anyone looking to look and feel better about their smile!!
