Does Teeth Whitening Work on Yellow Teeth?
Short answer
Yes. Yellow is the shade that responds best. The American Dental Association's consumer site says yellow teeth will probably bleach well, and Cleveland Clinic explains that yellow stains usually come from dark foods and drinks, the surface stains that whitening works on best.
Why are my teeth yellow?
- Food and drink. Cleveland Clinic lists coffee, tea, berries, red wine and soy sauce as common causes. The American Dental Association names coffee, tea and red wine as major staining culprits.
- Age. Over time enamel thins, and more of the yellowish dentin underneath shows through, the American Dental Association explains.
Which tooth stains respond best to whitening?
Yellow tones respond best, according to the American Dental Association. Brownish tones may respond less well, and grey tones the least. If your teeth have a grey cast, a dentist can tell you what will work.
What is the difference between surface and deep stains?
- Surface (extrinsic) stains build up on the enamel from coloured food, drink and tobacco. Cleveland Clinic says whitening works best on these.
- Deep (intrinsic) stains sit inside the tooth. Cleveland Clinic notes that some whitening products can remove deep stains too.
Peroxide gels work on both. Ultradent explains that the gel works on the enamel and the dentin underneath, breaking down the molecules that cause discoloration.
Which whitening option should you choose for yellow teeth?
- For speed and simplicity: Opalescence Go prefilled trays, 15 to 20 minutes a day for 5 to 10 days.
- To whiten overnight: Philips Zoom NiteWhite in custom trays.
- For a short daytime session: Philips Zoom DayWhite in custom trays.
How do you keep teeth from turning yellow again?
Brush twice a day, rinse with water after coffee or tea, and use occasional touch-ups. See how long whitening lasts.
