Teeth Whitening
Professional and at-home options for a brighter smile.
Overview
Teeth whitening is one of the most popular cosmetic dental procedures. It can significantly brighten your smile by removing stains and discoloration. Options range from professional in-office treatments to at-home products.
Causes of Tooth Discoloration
Teeth become discolored due to:
- Coffee, tea, red wine, and cola
- Tobacco use
- Aging (enamel wears, dentin shows through)
- Certain medications
- Trauma to teeth
- Excessive fluoride during development
- Genetics
Professional Whitening
In-office options include:
- Strongest whitening agents (up to 40% hydrogen peroxide)
- Results in one visit (about 1 hour)
- Can lighten teeth 3-8 shades
- Light or laser may be used to enhance results
- Cost: $300-$1,000 per session
At-Home Options
Over-the-counter choices include:
- Whitening strips (Crest Whitestrips)
- Whitening trays and gels
- Whitening toothpaste
- LED whitening kits
- Custom trays from dentist (take-home professional)
Safety & Side Effects
Whitening is generally safe when used as directed. Common side effects include temporary tooth sensitivity and gum irritation. These usually resolve within a few days of stopping treatment.
Frequently Asked Questions
How long do whitening results last?
Results typically last 6 months to 2 years, depending on your habits. Avoiding staining foods/drinks, not smoking, and touch-up treatments can extend results. Professional whitening tends to last longer than OTC products.
Can whitening damage enamel?
When used as directed, whitening products approved by the ADA are safe for enamel. Overuse or misuse can cause sensitivity and enamel damage. Always follow product instructions and consult your dentist.
Does whitening work on all types of stains?
Whitening works best on yellow/brown stains from food, drinks, and aging. It's less effective on gray stains (from medications or trauma) and won't change the color of fillings, crowns, or veneers.
Is professional whitening worth the cost?
Professional whitening delivers faster, more dramatic results with dentist supervision. It's worth considering if you want significant whitening quickly, have sensitive teeth, or haven't gotten results from OTC products.
