Stained teeth can be embarrassing — so much so you may even hesitate to smile. Before you seek out a whitening solution, though, there are a few things you need to know about tooth staining.
Tooth staining is more complex than you might think. There are actually two types: extrinsic, staining from foods and other substances of the outer surface of the enamel; and intrinsic, discoloration deep within a tooth that affects their outward appearance. The latter staining has a number of causes, including the type of dental materials used to fill a tooth, a history of trauma or the use of the antibiotic tetracycline during early tooth development.
There are some noticeable differences between the two types, although an examination is usually necessary to determine which you have. Extrinsic staining tends to be brown, black, or gray, or occasionally green, orange or yellow. Intrinsic staining can be red, pink or, if caused by tetracycline and fluoresced under ultraviolet light, yellow. If only one tooth is discolored it’s most likely intrinsic due to decay in the tooth pulp.
What can be done also depends on which type. Extrinsic staining can be modified through whitening, with either an office application or a home kit (there are differences, so you should consult with us before you decide). It may also be essential to modify your diet by restricting foods and beverages (coffee, wine or tea) known to cause staining and by eliminating tobacco use. You should also practice daily hygiene, including brushing with a toothpaste designed to diminish staining, and regular office cleaning and polishing.
Intrinsic staining can’t be addressed by these methods. Instead, you may need to undergo a procedure where we enter the interior of the tooth and insert a bleaching agent. If this isn’t an option, you can also choose a cosmetic restoration such as a porcelain veneer or crown that will cover the tooth to better match the color of your other teeth.
Dealing with stained teeth begins with a visit to our office to determine what type of discoloration you have and to learn your options. But regardless of what type you have, there is a way to a brighter smile.

So you’re tearing up the dance floor at a friend’s wedding, when all of a sudden one of your pals lands an accidental blow to your face — chipping out part of your front tooth, which lands right on the floorboards! Meanwhile, your wife (who is nine months pregnant) is expecting you home in one piece, and you may have to pose for a picture with the baby at any moment. What will you do now?
Take a tip from Prince William of England. According to the British tabloid The Daily Mail, the future king found himself in just this situation in 2013. His solution: Pay a late-night visit to a discreet dentist and get it fixed up — then stay calm and carry on!
Actually, dental emergencies of this type are fairly common. While nobody at the palace is saying exactly what was done for the damaged tooth, there are several ways to remedy this dental dilemma.
If the broken part is relatively small, chances are the tooth can be repaired by bonding with composite resin. In this process, tooth-colored material is used to replace the damaged, chipped or discolored region. Composite resin is a super-strong mixture of plastic and glass components that not only looks quite natural, but bonds tightly to the natural tooth structure. Best of all, the bonding procedure can usually be accomplished in just one visit to the dental office — there’s no lab work involved. And while it won’t last forever, a bonded tooth should hold up well for at least several years with only routine dental care.
If a larger piece of the tooth is broken off and recovered, it is sometimes possible to reattach it via bonding. However, for more serious damage — like a severely fractured or broken tooth — a crown (cap) may be required. In this restoration process, the entire visible portion of the tooth may be capped with a sturdy covering made of porcelain, gold, or porcelain fused to a gold metal alloy.
A crown restoration is more involved than bonding. It begins with making a 3-D model of the damaged tooth and its neighbors. From this model, a tooth replica will be fabricated by a skilled technician; it will match the existing teeth closely and fit into the bite perfectly. Next, the damaged tooth will be prepared, and the crown will be securely attached to it. Crown restorations are strong, lifelike and permanent.
Was the future king “crowned” — or was his tooth bonded? We may never know for sure. But it’s good to know that even if we’ll never be royals, we still have several options for fixing a damaged tooth.
