Teeth Whitening That Actually Works
Whitening is the most requested cosmetic treatment in dentistry and the one most often attempted badly at home.

Surface stain versus internal color
Coffee and tea create extrinsic staining that responds well to bleaching and even to a thorough cleaning. Discoloration from tetracycline, trauma or aging is intrinsic, sits deeper in the dentin, and will not respond the same way. Knowing which you have prevents disappointment.
Why professional gel differs
Professional systems use higher, better-buffered concentrations applied with gum protection and custom trays that hold gel against the tooth rather than washing it away with saliva. Sensitivity is managed proactively with desensitizing agents rather than endured.
Protecting the result
Rinse with water after staining drinks, use a straw for iced coffee and tea, keep your six-month cleanings, and run a short touch-up with your take-home trays once or twice a year. That routine holds a shade for a very long time.
