Whitening uses peroxide-based chemistry to lighten natural tooth structure. It does not change crowns, veneers, fillings, or implant restorations. An examination before whitening helps identify cavities, cracked teeth, gum recession, and existing sensitivity that may need attention first.
In-office vs. take-home whitening
| Option | Typical experience | Trade-off |
|---|---|---|
| In-office | Clinician-controlled gel and soft-tissue protection | Faster appointment-based brightening; sensitivity can occur |
| Custom take-home trays | Gradual whitening with a dentist-provided plan | More control at home; requires consistency |
| Over-the-counter products | Varying concentrations and tray or strip designs | Convenient, but fit and supervision vary |
Managing sensitivity
Sensitivity is often temporary but should be reported if severe or persistent. Your dentist may adjust concentration, wear time, frequency, or recommend a desensitizing product. Never leave gel on longer than directed, and do not use household peroxide in your mouth.
Set expectations before whitening
Natural teeth may not whiten evenly, and deep internal discoloration may respond differently from surface stains. Because restorations retain their original shade, whitening is often planned before replacing visible crowns, veneers, or bonding.
