Orthodontics is a specialty of dentistry dedicated to the diagnosis and treatment of misaligned teeth, or malocclusions. The goal is to help patients achieve better long-term oral health by improving teeth alignment. Sometimes, though, the misalignment is much more involved than the position of the teeth — it may be that the jaw structure is also misaligned. In that case, the skills of an oral surgeon may be in order.
The jaws are similar in shape to the arch of a horseshoe, hence the referral to either upper or lower sets of teeth as dental arches. In a normal jaw structure, the lower arch fits just inside the upper arch when you bite down and the teeth are able to function correctly. In some individuals, though, the lower arch closes in front of the upper arch, commonly known as an underbite. If the underbite is only slight, the malocclusion can be corrected by repositioning the teeth only, as with braces. If, though, the underbite is more severe it would require a surgical procedure to realign the jaws, also known as orthognathic surgery.
Orthognathic surgery can help relieve a number of functional complications caused by jaw-related malocclusions: difficulty chewing and swallowing; chronic jaw or head pain; or sleep apnea. It can also enhance the patient’s facial appearance by correcting an imbalance between the two lateral sides (asymmetry), or by minimizing a receding chin or protruding jaw.
Its primary benefit, though, is its effect on the patient’s bite and tooth alignment. For this purpose, the orthodontist and oral surgeon work together to achieve the best result possible. In some cases, the orthodontist may perform his or her work first by moving teeth into the proper position. This sets the stage for the oral surgeon to perform orthognathic surgery to complete the correction of the misalignment.
Each individual patient’s case is different — the best plan of action must begin with a full examination by an orthodontist, and a consultation with an oral surgeon if necessary. It may require time and the expertise of two specialties, but the final result will be better health and a better look.

What happens if you’re right in the middle of a song, in front of an arena full of fans… and you knock out a tooth with your microphone? If you’re Michael Buble, you don’t stop the show — you just keep right on singing.
The Canadian song stylist was recently performing at the Allphones Arena in Sydney, Australia, when an ill-timed encounter with the mike resulted in the loss of one of his teeth. But he didn’t let on to his dental dilemma, and finished the concert without a pause. The next day, Buble revealed the injury to his fans on his Instagram page, with a picture of himself in the dentist’s chair, and a note: “Don’t worry, I’m at the dentist getting fixed up for my final show tonight.”
Buble’s not the only singer who has had a close encounter with a mike: Country chanteuse Taylor Swift and pop star Demi Lovato, among others, have injured their teeth on stage. Fortunately, contemporary dentistry can take care of problems like this quickly and painlessly. So when you’ve got to get back before the public eye, what’s the best (and speediest) way to fix a chipped or broken tooth?
It depends on exactly what’s wrong. If it’s a small chip, cosmetic bonding might be the answer. Bonding uses special tooth-colored resins that mimic the natural shade and luster of your teeth. The whole procedure is done right here in the dental office, usually in just one visit. However, bonding isn’t as long-lasting as some other tooth-restoration methods, and it can’t fix large chips or breaks.
If a tooth’s roots are intact, a crown (or cap) can be used to replace the entire visible part. The damaged tooth is fitted for a custom-fabricated replacement, which is usually made in a dental laboratory and then attached at a subsequent visit (though it can sometimes be fabricated with high-tech machinery right in the office).
If the roots aren’t viable, you may have the option of a bridge or a dental implant. With a fixed bridge, the prosthetic tooth is supported by crowns that are placed on healthy teeth on either side of the gap. The bridge itself is a one-piece unit consisting of the replacement tooth plus the adjacent crowns.
In contrast, a high-tech dental implant is a replacement tooth that’s supported not by your other teeth, but by a screw-like post of titanium metal, which is inserted into the jaw in a minor surgical procedure. Dental implants have the highest success rate of any tooth-replacement method (over 95 percent); they help preserve the quality of bone on the jaw; and they don’t result in weakening the adjacent, healthy teeth — which makes implants the treatment of choice for many people.
So whether you’re crooning for ten thousand adoring fans or just singing in the shower, there's no reason to let a broken tooth stop the show: Talk to us about your tooth-restoration options!

Q: What exactly is cosmetic tooth bonding?
A: Cosmetic bonding is a process in which your dentist uses specially formulated tooth-colored material to repair minor defects on the surface of your teeth. The bonding material itself is a type of composite resin — a tough, translucent mixture of plastic and glass components that mimics the pearly-white appearance of your teeth to a high degree. The material also bonds (links up) so well with the natural tooth structure that this relatively simple and inexpensive treatment can last for a number of years.
Q: What types of defects can tooth bonding repair?
A: Bonding can be used to remedy several different kinds of flaws in your smile. Small chips, cracks and areas of discoloration can be easily treated via cosmetic bonding. It can even be used to fix minor spacing irregularities. Best of all, because composite resin is available in various shades to match the natural color of your teeth, it’s almost impossible to tell which tooth has been treated.
Q: What are the pluses and minuses of cosmetic bonding?
A: Bonding is a procedure that can be done right in the dental office, without involving a laboratory — that’s why it is typically an easy, cost-effective treatment that can be accomplished in a single visit. It’s a great solution for restoring minor flaws that don’t extend very far into the tooth’s structure. It’s also ideal for teenagers, who may have to wait until they stop growing before getting a more permanent restoration. But bonding normally isn’t as long-lasting as some other restoration techniques, such as veneers or crowns. However, with proper care, a bonded tooth can keep looking good for years.
Q: What is the bonding procedure like?
A: Bonding is a minimally invasive, reversible treatment that normally causes little or no discomfort. The tooth being treated is first thoroughly cleaned, and then “etched” with a gel that microscopically roughens its surface. Next, the gel is rinsed off, and liquid composite resin (in a shade chosen to match the tooth) is painted on with a brush. Then, the bonding material is cured (hardened) using a special light. After it has cured, another layer may be applied; this process can be repeated several times to build up a thicker coating. Finally, a dental instrument is used to shape the built-up material into its final, pleasing form.
Q: Do bonded teeth require special care?
A: Not really… but like all teeth, they should be brushed and flossed daily, and professionally cleaned at the dental office twice a year. Bonded teeth can also become stained from tobacco use, red wine and coffee — but unlike regular teeth, bonded teeth can’t be lightened. So if you’re considering tooth-whitening treatments, have them done before your teeth are bonded.
