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.

Tooth decay and periodontal (gum) disease pose the most common dangers to dental health. But there are some rare conditions that can also place teeth at risk to be on the lookout for during regular dental checkups.
One such condition is root resorption in an adult tooth, in which the root itself or its surface breaks down and is absorbed by the body. Resorption occurs naturally in a primary (“baby”) tooth so it can loosen and give way for an incoming permanent tooth. Â Resorption still occurs in a limited form with young permanent teeth but should eventually stop.
Sometimes, though, it doesn’t, either from the inside of the tooth out (internal resorption) or more often from the outside in, usually around the neck-like (or “cervical”) portion of the tooth. This more common occurrence, External Cervical Resorption (ECR), can first appear as pink spots on the enamel and then progress into cavity-like areas. If not found and treated promptly, damage can occur quickly and lead to tooth loss.
We don’t fully understand the exact nature and causes for ECR, but we have identified risk factors for its development. Excessive orthodontic force on the teeth or any other trauma can cause damage to the periodontal ligament (which holds teeth in place with the jaw bone). Teeth grinding habits and some dental procedures like internal tooth whitening can also be risk factors.That being said, though, the vast majority of people who experience these issues don’t develop ECR.
Although the causes aren’t fully understood, we can still treat it: the key to success is early detection. You probably won’t notice early signs of ECR, but we can often detect spots from routine x-rays. We can then remove the tissue cells within the lesions causing the damage and restore the area with a tooth-colored filling material. If ECR has extended near the tooth’s interior pulp layer, then a root canal treatment may be needed.
Needless to say, the more extensive ECR occurs in the roots, the less likely the tooth can be saved and may need to be extracted. It’s important, therefore, to maintain regular dental checkups (at least twice a year) to increase your chances of catching a developing problem early.
