Professional basketball player Lamar Odom is sometimes known as “the candyman” because of his notorious fondness for sweets. But when his sweet tooth finally caught up with him — in the form of a mouthful of decayed teeth — the six-foot-ten-inch, 230-pound hoops star admitted that he had been avoiding treatment… because he was afraid of going to the dentist!
It took two Kardashians (Khloe and Kim) and a painful toothache to finally persuade Odom to sit in the chair. Once he did, it was found that he needed a root canal, a wisdom tooth extraction, and several fillings. Yet the fretful forward sailed through the whole set of procedures in a single visit, and walked out with a big smile afterward. How did his dentists make that happen?
Put it down to the “magic” of sedation dentistry. With anxiety-relieving medications that can be delivered orally (in pill form or by gas) or intravenously (into the bloodstream), the techniques of sedation dentistry can help even the most fearful patients get the dental care they need. That’s good news for about 50 percent of the population, who admit they’re at least somewhat afraid of the dentist — and even better for the 15 percent who avoid dental care completely due to their fear.
Dentists have a number of ways to ease apprehensive patients through a dental visit. An oral anti-anxiety drug can be given in pill form about an hour beforehand. Nitrous oxide (sometimes called “laughing gas”), which is administered by a mask placed over the mouth or nose, may also be used to relieve anxiety. The calming effects of these medications help make any nervousness melt away — and in many circumstances, mild sedation is all that’s needed to ease the fear.
For lengthier or more complex procedures, intravenous (IV) sedation may be recommended. Unlike deeper (unconscious) sedation, IV sedation doesn’t cause “sleep.” Instead, it puts you in a comfortable semi-awake state, where you can still breathe on your own and respond to stimuli… but without feeling any anxiety. And when the procedure is over, you probably won’t have any memory of it at all.
IV sedation can be administered by dentists who are specially trained and equipped with the proper safety equipment. While sedation is being provided, you will be monitored at all times by a dedicated staff member; when it’s over, you will rest for a while as the medication quickly wears off. Then (as is the case with oral sedation), you’ll need another person to give you a ride home.
Does sedation dentistry really work? Lamar Odom thinks so. “I feel so much better,” he said when his 7-hour procedure was over. “I feel like I accomplished something.”
Accidents can happen to your mouth, especially if you have an active lifestyle. For example, a sudden blow to the jaw while playing sports or exercising could result in a chipped tooth. And, while the internal tooth structure may be fine, the effect on your appearance can be disheartening.
Fortunately, we have techniques and materials to restore your smile after an injury. Bonding with composite resin is one such procedure: it’s ideal for mild to moderate chipping, especially in highly visible front teeth.
Composite resin is a dental material made of various substances mixed to match the color and texture of natural teeth. The composite is usually made of inorganic glass filler blended with a plastic-based matrix and joined together with a chemical “coupling” agent. The ratio of filler to matrix will depend on the type of tooth and damage — for example, back teeth, which encounter higher biting forces, require a composite with more filler for added strength.
To begin the procedure, we first prepare the damaged tooth by applying microscopic etchings (often with a chemical solution) that create tiny depressions or “undercuts”: these help create a seamless bond between the composite and the natural tooth. We then apply the composite in layers with a bonding agent, building up layer upon layer until we’ve achieved the desired shape for the tooth involved.
Bonding with composite resins doesn’t require much tooth preparation, can be placed quickly and is relatively inexpensive. Because of the wide spectrum of color possibilities, composite resins are superior to traditional amalgam (metal) restorations in creating a more life-like appearance. Its application, however, can be limited by the amount of tooth structure needing to be replaced: because it isn’t as strong as the tooth structure it replaces, the more tooth structure the bonded composite resin attempts to replace the less likely it can stand up over time to normal bite forces.
Still, composite resins are ideal for mild to moderate damage or disfigurement. If you’ve suffered such an injury, be sure to visit us to see if bonding with life-like composites is the right solution for restoring your smile.
