What causes stains on our teeth?

No matter if you brush your teeth perfectly, if you had them whitened and do regular touch-ups, the youthful radiance of your teeth will fade with age. They lose their shine because over time the enamel develops microscopic cracks, and loses the crystalline rods that compose it.  The enamel layer will thin, increasing the transparency of the tooth to expose the more pronounced shade of the dentin within.  Beside aging, bad habits, food choices, medications, lifestyle and many other factors influence the appearance of your teeth.

External stains on the tooth result from the accumulation of food fragments and the colorant they contain. These surface stains can be removed by prophylactic cleaning and brushing with whitening toothpaste. A little baking soda added to the usual toothpaste gives very good results. But there are more stubborn stains lodged in the tiny microscopic cracks between the teeth. And one or more teeth whitening treatments may be required to dislodge them.  The older and deeper the stains, the more difficult it will be to remove them, because there’re located under the enamel. Professional treatment by a dentist will often be necessary to remove that type of stains.

The teeth can also be damaged over time in stressed people tending to cringe. Cringing often occurs at night, when the jaw is contracted and so we’re not aware of it.  This unconscious bad habit damages the teeth.  It can be overcome by sleeping with braces to isolate the upper and lower jaw because of course we can’t control the involuntary grinding.  While awake however, we must pay attention to teeth grinding to preserve our teeth.

Another important factor contributing to damage the teeth is smoking. The habit will quickly cause nicotine stains on the teeth and even brushing will fail to eliminate them completely. Nicotine also damages teeth because it affects the internal structure, contributing to premature aging of the teeth.

Red wine may be good for the heart, but it is not friendly to your teeth. It contains a high proportion of pigments that will stain the teeth over time. The same is true for some highly pigmented foods such as tomato sauce and berries.

Everyone’s teeth show some transparency.  The enamel layer is not completely opaque and in most peoples the color of the dentin within the tooth is visible.  It is the color of the dentin that determines the natural color of the tooth. Whitening treatments are sometimes counter-indicated for peoples whose teeth are completely or too largely transparent. In addition, no whitening treatment could bleach the tooth more than its natural color.

The possibilities for improving the cosmetic appearance of the teeth varies from one person to another, according to the factors listed above. You must therefore stick to realistic expectations when you choose a teeth whitening treatment. In cases where the whiteness of the teeth cannot be significantly improved, the look can be artificially improved by dental facelift.  But natural teeth remain natural teeth, with their history and limitations.  That’s why it’s important to see a dentist before undertaking any whitening treatment.
