Best way to have teeth whitened
The best whitening method depends on the cause of discoloration, tooth health, sensitivity, and whether visible restorations are present.
The short answer
The most suitable way to whiten teeth is a dental assessment followed by a measured peroxide treatment when natural teeth and gums are healthy; the best option differs for surface stains, internal discoloration, and restorations.
How does whitening differ from removing surface deposits?
Whitening lightens natural tooth structure by chemically changing stain molecules, while cleaning removes deposits on the surface. Crowns, veneers, fillings, and bonding do not bleach, so whitening can make their shade mismatch more visible.
What whitening options might a dentist recommend?
A dentist may recommend professional in-office whitening, custom take-home trays, or a lower-strength retail product depending on the examination. Treat cavities, gum inflammation, cracks, or exposed root surfaces first, and use a shade assessment before treatment.
When should a dentist assess discoloured teeth first?
Seek care before whitening if a tooth is gray, painful, sensitive, cracked, or darker than its neighbors. Dental review is also important when gum bleeding or untreated decay is present.
What should you ask about method, shade, and sensitivity?
Ask whether the discoloration is extrinsic or intrinsic, how existing restorations will look afterward, and which method balances shade change with sensitivity. Ask whether a cleaning or restorative treatment is more appropriate than bleaching.
Frequently asked questions
Is professional whitening always best?
Not automatically; suitability depends on tooth health, stain type, sensitivity, and restorations.
Why did whitening not remove a dark spot?
A dark spot may be internal decay, trauma-related discoloration, or a restoration rather than a surface stain.
