1. Follow the instructions included in your kit.
  2. Total treatment time is usually 2-3 weeks. Some cases may take longer, especially if treatment is interrupted.
  3. Make sure you brush and floss thoroughly prior to each treatment. The bleaching gel can work better if it is in contact with the tooth rather than plaque buildup.
  4. Mild sensitivity to cold liquids or air may occur. This usually passes a few days after treatment is completed. If the sensitivity is severe or persists, discontinue using the gel and contact our office.
  5. If you experience any gum irritation, let us know. Your custom tray may need to be adjusted.
  6. Whitening works best on yellow stained teeth. Gray teeth are more difficult to whiten, or may not respond to treatment. Such cases may require porcelain veneers to achieve the desired result.
  7. Results can be quite dramatic. However upon completion of the whitening process, the color will “tone down” somewhat. This is normal and actually looks more natural.
  8. Long-term results vary from patient to patient. This can depend on many factors including habits such as smoking or coffee, tea, wine, or cola consumption.
  9. “Touch-up” treatments may be needed every 3-6 months. This can usually be accomplished in 1 or 2 treatments of 1 – 2 hours each. A special touch-up kit is available at our office.
  10. Existing fillings, crowns, bonding, etc. will not whiten. Therefore, these restorations may need to be changed in order to match your new smile.
  11. It is important to keep your 2-week follow-up appointment so we can assess the results or make changes in treatment as needed.
  12. If you have unsightly old silver fillings ask us about changing them to invisible white fillings. Old crowns with dark gum-lines can be changed to more natural looking metal-free porcelain crowns.

If your friends wonder why you are smiling so much, tell them about us. It would be our pleasure to help them improve their smiles, too!
