Home Teeth Whitening: What Actually Works — And What Can Damage Your Teeth

* Brush twice a day with fluoride toothpaste
* Floss or clean between teeth daily
* Limit frequent staining drinks
* Rinse with water after coffee or tea
* Avoid tobacco
* Attend regular dental cleanings
* Use approved whitening products when desired

Good oral hygiene removes the buildup that can make teeth look dull or yellow.

## How to Reduce Coffee and Tea Stains

You do not necessarily have to give up coffee or tea.

Try:

* Drinking water afterward
* Avoiding sipping slowly for hours
* Cleaning your teeth regularly
* Using a straw for some cold drinks
* Getting professional cleanings when needed

Wait a little before brushing immediately after highly acidic drinks because enamel may be temporarily softened.

## When Whitening Should Be Avoided

Talk to a dentist before whitening if you have:

* Sensitive teeth
* Gum disease
* Cavities
* Exposed tooth roots
* Cracked teeth
* Dental restorations in visible areas

Fillings, crowns, and veneers do not whiten the same way as natural teeth.

That can create uneven color.

## When Yellow Teeth Are Actually Normal

Teeth are not naturally bright white.

Healthy teeth can be:

* Ivory
* Cream-colored
* Light yellow

Dentin, the layer beneath enamel, naturally has a yellowish color.

So some yellow tone is completely normal and does not mean your teeth are dirty.
