How do dentists treat discolored teeth?
Dentists use different tooth discoloration treatments depending on the underlying cause and whether the stains affect the outer or inner layers of your teeth.
Teeth whitening
Dentists may offer in-office or at-home professional teeth whitening treatments. These methods use hydrogen peroxide or carbamide peroxide to break up stains and lift them from your teeth. Professional whitening works best on surface (extrinsic) stains. But some whitening products can remove deep dental (intrinsic) stains, too.
In-office bleaching takes about one hour to complete. Most take-home whitening treatments require 30- to 60-minute daily treatments for up to six weeks. There are pros and cons to each. Ask your dentist which option is right for you.
Dental bonding
If you have deep tooth discoloration that doesn’t improve with whitening, your dentist may recommend dental bonding. This procedure involves applying tooth-colored composite resin to conceal discolored teeth.
Bonding is much more affordable compared to other options (like porcelain veneers), but you’ll probably need touch-ups every five to seven years. Dental bonding might not be the best option if you have several discolored teeth.
Porcelain veneers
If you have widespread tooth discoloration that doesn’t improve with whitening, you may want to consider porcelain veneers. These tooth-colored ceramic shells are thin, yet strong. A dentist permanently bonds (glues) them to the front surfaces of your teeth to camouflage discoloration or other cosmetic flaws like chipping or misshapen teeth.
A dentist has to replace porcelain veneers every five to 15 years. Veneers aren’t reversible.
Dental crowns
Sometimes tooth discoloration is a symptom of cavities. If you have weakened or decayed teeth in addition to discoloration, your dentist may recommend dental crowns.
A crown is a tooth-shaped cap that fits over your tooth, protecting it from further damage. Dental crowns help improve the health and function of your teeth as well as their appearance.

How can I fix discolored teeth at home?
You can find over-the-counter (OTC) teeth whitening treatments in any oral health aisle. These products include rinses, pastes, strips and do-it-yourself bleaching trays.
While some over-the-counter products are safe and effective, others can damage your enamel and make your teeth more vulnerable to cavities and erosion. That’s why it’s important to talk to your dentist before making a purchase.
In general, ingredients to avoid include:
- Baking soda (sodium bicarbonate).
- Activated charcoal.
- Citric acid.
When shopping for teeth whitening products, look for the ADA Seal of Acceptance. This means that experts have tested the safety and effectiveness of these products and deemed them safe for use.
Can I prevent tooth discoloration?
While you can’t prevent deep dental stains due to trauma, medications or health conditions, there are things you can do to reduce your risk of everyday surface discoloration:
- Brush your teeth two to three times a day using a soft-bristled brush and ADA-approved fluoride toothpaste.
- Floss between your teeth once a day.
- Limit foods and drinks that stain teeth, like tea, coffee, cola and red wine.
- Drink lots of water and rinse your mouth after drinking beverages that could cause tooth discoloration.
- Quit smoking.
- Visit your dentist for routine cleanings and exams.
