Almost everyone wants a bright, white smile. Unfortunately, human teeth are prone to become discolored over time. Why does that happen, and what can you do to get rid of pesky discoloration? In this blog post, we answer that question by explaining the three types of tooth stains and the methods that may be able to reduce or eliminate them.
Extrinsic Stains
An extrinsic tooth stain is one that occurs on the tooth’s surface. This type of discoloration is usually a direct result of what you put in your mouth. For example, avid coffee and tea drinkers often struggle with recurrent extrinsic stains, as do people who use tobacco products.
Fortunately, extrinsic stains are usually not difficult to get rid of. In most cases, a high-quality whitening toothpaste is able to do the trick. Such toothpastes are slightly abrasive, which means they can buff away stains. They may also contain a low concentration of a whitening agent (usually hydrogen peroxide).
Intrinsic Stains
When pigment molecules work their way from a tooth’s surface into the deeper portion of the enamel, you have what is known as an intrinsic stain. Intrinsic stains usually have the same causes as extrinsic stains. Unfortunately, though, intrinsic stains are a bit tougher to get rid of.
To effectively reduce or eliminate intrinsic stains, you will probably need the help of your cosmetic dentist. After they examine your teeth, they may recommend a professional whitening treatment. Professional treatments contain higher concentrations of whitening agents than anything you can buy over the counter. They are able to penetrate the enamel and break-up even deep-set stains.
Age-Related Stains
It is common for older individuals to have noticeably yellow teeth. This can happen due to the cumulative effects of years of intrinsic and extrinsic stains combined with thinning dental enamel. As the enamel becomes worn down, it becomes easier to see through. Since the tooth layer beneath the enamel, the dentin, is naturally yellow, it becomes more visible and can make the teeth look dull and discolored.
If you are up in years and wish to brighten your smile, you have a few different options. Your dentist might recommend that you try a professional whitening treatment. Or, you might consider getting veneers. Veneers do not actually change the color of your teeth. Rather, they conceal your teeth with natural-looking, tooth-colored porcelain. You can even choose the color of your veneers. Many older individuals choose a subdued and natural-looking shade, rather than the gleaming white color that is popular among people who are in their early adulthood.
Are dental stains getting you down? Your dentist can advise you on how best to fight discoloration and achieve the bright, youthful smile that you deserve.
