I visit Dr. Glennon on a regular basis and recently decided to get my teeth whitened for an upcoming family member's wedding. Since I hate my yellow teeth, I tend to not smile big in pictures. I knew I was going to be in the majority of the wedding pictures, so I decided to try whitening my teeth. WOW! I really don't know why I haven't done it before! I guess I heard somewhere that yellow teeth can't get much whiter and thought 'why be disappointed?' I was Wrong. If you have yellow teeth, I would recommend getting your teeth whitened. And if you live in Austin, I would recommend this dentist office!
