We all want a bright, vibrant smile that lasts a lifetime. Yet there are many factors that can cause teeth to become stained or discolored over time. Some of these are external—like the food and drink we consume. Coffee, cola drinks, red wine, and even certain fruits and vegetables can discolor tooth enamel over time. Tobacco (whether smoked or chewed) can also stain the dentin a yellow-brown color. Other factors in dental staining are related to medications and other agents. Exposure to tretracycline-based antibiotics—whether in utero or during childhood—can predispose our teeth to lose their luster. Even childhood exposure to high levels of fluoride (even though protective against decay) can dull our smiles. Some antihistamines and blood-pressure-lowering medications can also have staining effects on teeth. Certain diseases can also result in tooth discoloration. And even beneficial treatments like chemotherapy and radiation can affect enamel development and negatively impact tooth whiteness. And of course, there’s poor dental care. Without adequate brushing and flossing, stain-producing compounds can build up on teeth and eventually stain the dentin. Even if we manage to avoid all these external causes, the natural aging process can cause our teeth to become gray and stained. As the outer layer of enamel wears away and pulp size decreases, teeth can become more translucent, allowing the more yellow color of the dentin to show through. Fortunately, there is a solution. Consistent and appropriate dental care, along with safe and approved whitening agents can help to restore the glamorous smile that food, chemical agents, and age have taken away.
