Professional Teeth Whitening: Safe Facts vs Over-The-Counter Myths
Published on November 19, 2023 • By Dr. Meg Cashman
Why custom dentist-supervised whitening trays are safer and far more effective than cheap online bleaching kits or charcoal toothpaste.
Many over-the-counter whitening kits contain abrasive chemicals or unauthorized acidic concentrations that strip natural tooth enamel.
### Why Choose Dentist-Supervised Whitening:
- **Custom-Molded Trays:** Seal the gel against your teeth and protect delicate gums from chemical burn.
- **Enamel-Safe Formulation:** Whitens internal dentin shade without eroding protective outer enamel.
- **Predictable Results:** Lightens teeth by 4–8 shades safely and evenly within 10–14 days.
