Teeth whitening treatment is a cosmetic dental procedure that aims to lighten the color of teeth and remove stains or discoloration. It is typically sought by patients who desire a brighter, more attractive smile.
Purpose of Whitening
The purpose of teeth whitening is to enhance the appearance of teeth by removing surface stains and deep discoloration caused by various factors, such as aging, consumption of staining substances (coffee, tea, red wine), smoking, or poor dental hygiene. It boosts self-confidence and rejuvenates the smile.
How Teeth Whitening Works
Teeth whitening treatments use active bleaching agents, usually hydrogen peroxide or carbamide peroxide, to break down stains into smaller particles, making the color less concentrated and the teeth brighter. The oxygen released by the bleach lifts stains from both the enamel (outer layer) and dentin (inner layer) of the teeth.
Different Methods of Whitening
There are two primary methods of teeth whitening: in-office professional whitening and at-home whitening kits. In-office whitening involves a higher concentration of bleaching agents and can provide quicker and more dramatic results. At-home kits involve custom-made trays or strips with a milder bleaching agent, used over several days or weeks.
Potential Side Effects or Risks of Whitening
Some patients may experience temporary tooth sensitivity or gum irritation during or after the whitening process. Overuse of whitening products or using solutions with high concentrations of bleach without professional guidance can lead to enamel erosion or tooth sensitivity. Properly supervised treatments minimize these risks. (See below for more information on treating teeth sensitivity)
Duration of Whitening Results
The longevity of teeth whitening results varies among individuals based on lifestyle habits and oral care. With proper maintenance, teeth whitening effects can last from several months to a few years. Avoiding staining substances, practicing good oral hygiene, and periodic touch-ups can help prolong the results.
Dental patients should consult with the dentist to determine the most appropriate teeth whitening method and ensure they are good candidates for the treatment. Professional supervision ensures safe and effective teeth whitening with minimized risks and optimal results.
Tooth Sensitivity Following Whitening
If tooth sensitivity or “Zingers” occur following teeth whitening treatment, several treatments and strategies can help alleviate the discomfort:
- Toothpaste for Sensitive Teeth: Switch to a toothpaste specifically designed for sensitive teeth. These toothpaste formulations contain ingredients that help desensitize the nerves in the teeth, reducing sensitivity.
- Fluoride Application: Your dentist may apply a fluoride gel or varnish to the sensitive teeth. Fluoride helps strengthen the enamel and reduce sensitivity.
- Desensitizing Gel or Rinse: Over-the-counter or prescription desensitizing gels or rinses can be applied to the sensitive areas to provide relief.
- Avoiding Triggers: Limiting or avoiding hot, cold, sweet, or acidic foods and drinks can help prevent exacerbating tooth sensitivity.
- Soft-Bristled Toothbrush: Use a soft-bristled toothbrush and a gentle brushing technique to reduce enamel wear and irritation.
- Custom Tray with Desensitizing Gel: If you used an at-home whitening kit, your dentist may provide a custom tray with a desensitizing gel to apply to the sensitive teeth.
- Reduce Whitening Frequency: If you were using an at-home whitening kit, spacing out the treatment sessions or reducing the frequency can help minimize sensitivity.
- Professional Evaluation: If the sensitivity is severe or persists, consult your dentist. They can assess the cause of sensitivity and recommend further treatments or adjustments.
- Avoid Over-Whitening: Overusing teeth whitening products can lead to increased sensitivity. Follow the manufacturer’s instructions or your dentist’s recommendations for the treatment duration.
- Prescription Medication: In some cases, your dentist may prescribe a desensitizing toothpaste or recommend other prescription-strength treatments to manage sensitivity.
It’s essential to communicate any tooth sensitivity experienced after teeth whitening with your dentist. They can tailor a treatment plan to address your specific needs and help you achieve a brighter smile while minimizing discomfort.
