Whiter Teeth: Is It a Myth that They Are Healthier?

Whiter teeth are not necessarily healthier or stronger teeth. Teeth with a light yellow cast are normal. Dark spots or heavy stains are a different matter, and are worth having checked.

Science Focus explains why natural teeth are not pure white. Enamel is whitish-blue and translucent, and the dentin underneath is light gray or yellow. Because the enamel is see-through, the dentin color shows through, giving teeth a slightly yellow or gray cast. Natural teeth are usually a few shades darker than white paper or piano keys.

Can Bleaching Harm Teeth?

It can. Bleaching products can irritate gums and cause tooth sensitivity, and overuse can wear on enamel. Follow the directions, and ask your dentist what is right for you.

What Foods and Drinks Stain Teeth?

• Coffee, tea and dark sodas
• Red wine
• Dark sauces and dressings, such as balsamic vinegar and tomato-based sauces

Rinsing your mouth with water after these helps limit staining.

Gentle Ways to Brighten Your Smile

• Toothpaste with baking soda. It helps lift surface stains and plaque.
• Professional whitening or dentist-provided whitening trays. A dentist can check that your teeth and gums are healthy first and set the right strength. See professional teeth whitening.
