Brightening Stained or Discolored Teeth

Discolored teeth can make you self-conscious, but the right fix depends on why your teeth are discolored in the first place. Not all stains respond to whitening, so understanding the type of discoloration is the key to brightening your smile effectively. Here is what you need to know.

Surface stains

The most common type, surface stains, sit on the enamel and come from foods, drinks, and tobacco. These respond well to professional whitening and good cleaning habits. If your discoloration is from years of coffee or red wine, whitening is usually the answer.

Deeper, internal discoloration

Sometimes the color change comes from within the tooth. This can be caused by aging, certain medications, an old injury, or a tooth that has had a root canal. Internal discoloration does not respond to regular whitening, so it calls for a different approach.

Matching the treatment to the cause

• Surface stains: professional whitening and regular cleanings
• Internal discoloration: veneers or bonding to cover the tooth, or specialized whitening for a single darkened tooth
• A single dark tooth after injury or root canal: often best addressed with a veneer, crown, or internal whitening

Why an exam matters first

Because the right treatment depends on the cause, a quick exam is the best starting point. Your dentist can identify what is behind your discoloration and recommend the approach that will actually work, rather than leaving you to guess with over-the-counter products.

Frequently Asked Questions

Why won't whitening work on my teeth?

Whitening works on surface stains but not on internal discoloration from aging, medication, injury, or a root canal. Those often need veneers or bonding instead.

What causes a single dark tooth?

A single darkened tooth is often the result of an old injury or a root canal. It is usually best treated with a veneer, crown, or internal whitening.

How do I know which whitening treatment I need?

A quick exam identifies the cause of your discoloration so your dentist can recommend the treatment that will actually work for your teeth.
