Over-the-Counter vs. Professional Teeth Whitening

Teeth Whitening in St Paul MN, Highgrove Dental Care

White teeth project the image of health and youth. Unfortunately, our teeth darken naturally as we age and become stained even faster with lifestyle habits such as coffee consumption and tobacco use.

You may be wondering what is the best way to whiten your teeth? Advertisements on television make over-the-counter teeth whitening seem appealing. What they don’t tell you, however, is that the best whitening results occur under the supervision of an experienced dentist.
