Get whiter teeth
Whiter teeth usually require a dental check followed by peroxide-based bleaching suited to the teeth and existing restorations.
The short answer
Whiter teeth are usually achieved with peroxide-based bleaching after a dentist checks for decay, gum disease, exposed roots, and restorations. Whitening changes natural tooth color but does not lighten fillings, crowns, veneers, or bonding.
How do peroxide gels break down tooth stains?
Hydrogen peroxide or carbamide peroxide moves through enamel and dentin and breaks down some stain molecules. Surface stains may also improve with professional cleaning, while internal discoloration may need a different treatment.
What should you do before using a whitening product?
Have a dental examination and cleaning first, then follow the prescribed product concentration, contact time, and tray fit. Reduce staining drinks and tobacco exposure, and pause the product if significant sensitivity or gum irritation develops.
When should tooth pain or darkening be assessed first?
Seek assessment before whitening if teeth hurt, gums bleed, enamel is cracked, or a tooth has a darkened color. Contact the dentist for persistent pain, chemical irritation, or uneven color after treatment.

Can home care replace a dental examination?
