What Causes Stained Teeth?

WE OFTEN TAKE STEPS to achieve that sparkling white smile when we brush in the morning and before we go to bed. The truth is, what we consume throughout the day is often the largest contributor to whether or not our smile will light up a room.

Although there are several causes for tooth discoloration, we can separate them into three basic categories: intrinsic, extrinsic, and age-related discoloration. Here’s how each affects your teeth, and what you can do to ensure a life full of bright, healthy smiles.

Food And Drink Are Large Contributors To Surface Stains

Extrinsic tooth discoloration occurs when the enamel—the outer layer of the tooth—becomes stained. These stains are caused by pigments, acidic content, and other chemical factors (natural or artificial) present in things we enjoy eating and drinking.

A few common culprits for tooth discoloration include:

• Wine
• Coffee
• Tea
• Cola
• Sports drinks
• Hard Candy
• Berries
• Tomato Sauce

Most of these items won’t have an immediate affect on the color of your teeth, but over time, they can begin to wear away and cling to enamel causing unsightly stains. Try to consume these in moderation and always remember to drink plenty of water and brush your teeth after meals.

Trauma Can Discolor Teeth From The Inside Out

Intrinsic tooth discoloration occurs when the inner structure of the tooth—the dentin—begins to darken or develop a yellow tint. This type of discoloration can develop because of a trauma sustained to the tooth. Sometimes when a tooth sustains trauma during childhood, it can damage the developing permanent tooth beneath it, affecting the tooth's color. If a trauma is sustained during adulthood, internal bleeding can potentially discolor the damaged tooth.

Other causes include uses of medication at certain stages of life or being born with a rare condition called dentinogenesis imperfecta which can cause gray, amber, or purple discolorations. 

Your Smile Can Change Color With Age

Age-related tooth discoloration is a combination of both intrinsic and extrinsic factors. The dentin inside our teeth naturally yellows as we age. Enamel on the outside of teeth also thins as we get older, allowing the yellow pigment of the dentin to show through. A lifetime of consuming certain foods or smoking cigarettes will also contribute to deep-set stains on the enamel’s surface.
