Why Teeth Change Color
Teeth naturally darken with age as enamel thins and the underlying dentin shows through. Coffee, tea, red wine, tobacco, and certain foods can add surface and deeper stains. Some discoloration comes from within the tooth, such as from certain medications, trauma, or excess fluoride during childhood, and these intrinsic stains may respond differently to whitening.
How Whitening Works
Professional whitening uses peroxide-based gels to break down stain molecules within the enamel. Options include in-office treatment, which uses a stronger gel under careful supervision, and take-home kits with custom-fitted trays that allow gradual whitening over a period of days or weeks.
Whitening affects natural tooth structure only. Crowns, veneers, bonding, and fillings will not change color, which is worth considering if you have visible restorations.
Sensitivity and Safety
Temporary tooth sensitivity and mild gum irritation are the most common side effects, and they usually fade after treatment. An exam beforehand ensures any cavities or gum concerns are addressed first, and professionally supervised whitening helps keep the process comfortable and predictable.
Keeping Results Bright
Results vary from person to person and gradually fade over time. Rinsing after dark beverages, maintaining good home care, and keeping regular cleanings all help. Occasional touch-ups can refresh your shade when you feel it is needed.
