What Causes Tooth Staining?

Many factors cause and aggravate tooth staining, including age, starting color, translucency and thinness, , smoking habits, drugs and chemicals, grinding, and trauma.

A direct correlation exists between tooth color and age. Usually, the older the teeth the more the teeth are stained due to accumulation and general wear and tear. Teenagers will likely experience immediate, drastic results from whitening because their teeth have not accumulated a large build up of stains. In the twenties when the teeth begin to show a yellow cast, teeth-whitening may require slightly more effort. Teeth in their forties begin to change hues from yellow to brown, indicating more maintenance in teeth-whitening efforts. By the fifties, the teeth have absorbed a host of stubborn stains which can prove difficult, but not impossible, to remove.

The starting color of teeth varies from person to person and ranges from yellow-brownish to greenish-grey and becomes more pronounced as we age. Yellow-brown is generally more responsive to bleaching efforts than green-gray.

The genetic traits of translucency and thinness become more apparent over time. While all teeth show some translucency, those that are opaque and thick have an advantage: they appear lighter in color, show more sparkle and are more responsive to bleaching. However, teeth that are thinner and more transparent (most apparent in the front teeth) may not be able to be bleached as the teeth lack the necessary pigment. According to , transparency is the only condition that cannot be corrected by any form of teeth whitening.

Eating habits are a contributing factor in tooth staining. The habitual consumption of , coffee, tea, cola, carrots, oranges and other deeply-colored beverages and foods causes considerable staining over the years. Enamel erosion is caused, in part, by consuming citrus fruits, vinegar and other acidic items. When combined, these two factors cause the surface of the tooth to become more transparent and more of the yellow colored dentin shows through.

Smoking habits can alter the color of teeth. Smoking has been proven to leave brownish deposits which slowly soak into the tooth structure and cause intrinsic discoloration.

Drugs and chemicals can have an adverse effect on tooth color. The antibiotic tetracycline when used during a child’s formative years, produces dark grey or brown ribbon stains which are extremely difficult to remove. Excessive consumption of fluoride causes a condition known as fluorosis which is associated with areas of mottling.

Grinding your teeth can affect tooth color. Most frequently caused by stress, teeth grinding can add to micro-cracking in the teeth and can cause the biting edges to darken.

Question about teeth?

I’m getting my teeth bleached by the dentist soon, and my teeth are stained from not taking care of them from when I was young, like I never brushed them at all, and the stains are kinda yellowish brown, will bleaching get rid of these stains and are they tetracycline stains?

This is something I do myself GENTLY.I am a smoker.I used to get brown bits on my teeth.Now the dentist gives teeth a scrape and polish,before I go I gently take my tweezers and scrape the brown of.you will find it comes of quite easily.gently.you dont want to ruin your enamel.
