Glo of Lake Norman
Glo of Lake Norman wants to bring whiter, healthier teeth to everyone, using safe and affordable teeth-whitening technologies. Certified technicians apply a special gel to the teeth and aim a cold blue LED light at teeth, which works with the gel to break up deep surface stains. Sessions last 15–45 minutes and whiten teeth 2–10 shades.
