“To gain something, sometimes you have to give up something else.”
No, that isn't the latest viral meme on the Internet. It's actually a practical consideration that could arise in orthodontics.
In this case, the “something” to gain is a straighter, more attractive smile; the “something” you may have to part with is a few teeth. This may be necessary if there are too many teeth on a dental arch for its capacity, a situation called crowding. A lack of space is the main reason teeth come in misaligned.
Before we can correct this, we'll need to free up space to allow for tooth movement by removing one or more of the existing teeth. The ideal candidates are those that are near to the teeth we wish to move but not highly visible. The first bicuspids are the most frequent choices for removal: they're located behind the cuspids or eyeteeth (the pointed teeth right under the eyes).
Ideally, we'll remove the target teeth some time before we apply braces to give the gums a chance to heal. At the same time we want to preserve the bone that once supported the teeth we've extracted. This is because when we chew the forces generated by the teeth stimulates bone replacement growth. When a tooth is no longer there the supporting bone doesn't receive this stimulation and may ultimately reduce in volume.
We may try to prevent this by placing a bone graft in the empty socket immediately after removing the tooth. The graft serves as a scaffold to encourage new bone to grow. Hopefully when we're ready to apply braces, the bone will be strong and healthy to handle the movement of the teeth.
As the teeth move under the influence of braces, they'll begin to fill up the space created by tooth removal. Once it's completed, the extracted teeth won't be missed — the other teeth now straightened will completely fill out the smile.
The different steps in this process must be carefully planned and executed precisely, and it will take months or even years to complete. In the end, though, this complicated bite problem can be corrected and replaced with an attractive, straight smile.

Gum recession — when the gum tissue covering teeth wears away — is a serious matter. If the roots become exposed you'll not only have increased sensitivity and possible discomfort, your teeth can become more susceptible to decay.
There are a number of reasons for gum recession, including overaggressive brushing and flossing, poor fitting appliances like dentures or braces, or genetics (inheriting a thin gum tissue type or poor tooth position). Perhaps the most common reason, though, is periodontal (gum) disease. Caused by bacterial plaque, a thin film of food particles that builds up on tooth surfaces, the disease weakens the gum tissues around teeth, causing them ultimately to detach and “roll up” toward the roots.
Treating the gum infection by removing the built-up plaque and calculus (hardened plaque deposits) will help stop recession or even reverse it. Â As we remove plaque the infection subsides and the gums cease to be inflamed. If they haven't receded too far they may re-grow and renew their attachment to the teeth.
In other cases, though, the recession may have progressed too far and too rapidly toward root exposure. Gums in this condition may require tissue grafts to the recessed area to create or regenerate new tissue.
Most grafting techniques fall into one of two categories. The first is known as free gingival grafting where a thin layer of skin is removed or "freed" from the roof of the patient's mouth (the palate), shaped and then stitched to the recession site.
The second category is called connective tissue grafting, most often used to cover exposed roots. In this case the donor material is transplanted from the donor site to the recipient site, but the recipient site's tissue covers the donor connective tissue graft as it still maintains a physical attachment to the original location. The recipient site can thus maintain a blood supply, which can result in quicker, more comfortable healing than with free gingival grafting.
Connective tissue grafting does, however, require sophisticated microsurgical techniques, along with the surgeon's in-depth skill and art, to prepare both the donor and recipient sites. Allografts (donor skin from another person) may also be used as a donor tissue and placed beneath the recipient site tissue thereby avoiding a second surgical site.
Gum tissue grafting can be an intense undertaking, but the results can be astounding. Not only will restoring recessed gum tissues give your teeth a new lease on life, it will revitalize your smile.

A lot happens in your child’s mouth from infancy to early adulthood. Not surprisingly, it’s the most active period for development of teeth, gums and jaw structure. Our primary goal as care providers is to keep that development on track.
One of our main concerns, therefore, is to protect their teeth as much as possible from tooth decay. This includes their primary (“baby”) teeth: although your child will eventually lose them, a premature loss of a primary tooth to decay could cause the incoming permanent tooth to erupt out of proper position. And we of course want to protect permanent teeth from decay during these developmental years as well.
That’s why we may recommend applying topical fluoride to your child’s teeth. A naturally occurring chemical, fluoride helps strengthen the mineral content of enamel. While fluoride can help prevent tooth decay all through life, it’s especially important to enamel during this growth period.
Although your child may be receiving fluoride through toothpaste or drinking water, in that form it first passes through the digestive system into the bloodstream and then to the teeth. A topical application is more direct and allows greater absorption into the enamel.
We’ll typically apply fluoride in a gel, foam or varnish form right after a professional cleaning. The fluoride is a much higher dose than what your child may encounter in toothpaste and although not dangerous it can cause temporary vomiting, headache or stomach pain if accidentally swallowed. That’s why we take extra precautions such as a mouth tray (similar to a mouth guard) to catch excess solution.
The benefits, though, outweigh this risk of unpleasant side effects, especially for children six years or older. Several studies over the years with thousands of young patients have shown an average 28% reduction in decayed, missing or filled teeth in children who received a fluoride application.
Topical fluoride, along with a comprehensive dental care program, can make a big difference in your child’s dental care. Not only is it possible for them to enjoy healthier teeth and gums now, but it could also help ensure their future dental health.

While it may not be one of your favorite features in the dental office, the dental drill is nevertheless necessary for treating problem teeth. It’s used primarily for removing decayed or damaged structure and preparing a tooth for fillings or other restorations.
Dental drills have been used for decades and are quite effective — but they have their drawbacks. Their rotating burrs often remove portions of healthy tooth structure along with decayed material. Friction from the drill action can cause discomfort, so local anesthesia is usually needed. Drills can also emit a high-pitched machine noise that’s unsettling to many patients.
There’s a growing alternative to the drill, known as air abrasion. Although the technology has been around since the 1950s, the development of new suction pumps that capture the resulting dust from its use has made it more palatable as an option to the traditional drill.
Also known as particle abrasion, the technique uses a pressurized stream of fine particles (usually aluminum oxide, an abrasive powder) directed at teeth to wear away (abrade) the tooth’s structural surface. We can be quite precise in the amount of surface material removed, so it’s useful for diminishing stains or roughing the surface for bonding materials like composite resin. We’re also able to remove decayed material with very little impact on surrounding healthy structure, and you may not need anesthesia during the procedure.
While this quiet alternative to the noisier drill is quite versatile, it does have its limitations. It’s not that efficient for preparing larger cavities for restoration or for removing older amalgam fillings. The teeth to be treated must be carefully isolated to prevent the fine particle dust produced from being swallowed by the patient or spread into the air. High-volume suction equipment is a must or the procedure will create a “sandstorm” of particles in the room.
Still, for situations suited to it and with proper isolation measures, air abrasion can be effective and comfortable. If the technology continues to improve, the dental drill may soon become a relic of the past.

It’s something you think about often—especially when you look in a mirror or at a photo of yourself. You wish something could have been done about it a long time ago. But now you think you’re too old to correct your misaligned teeth—your “crooked” smile.
Actually, you can transform your smile through orthodontics, whatever your age. Millions of your peers have done just that—currently, an estimated one in five orthodontic patients is an adult.
If orthodontics isn’t right for you it won’t be because of age, but most likely the condition of your gums and underlying bone or your overall health. That first factor is extremely important: if you’ve lost a significant amount of bone due to periodontal (gum) disease, there may not be enough to support the force of moving the teeth during orthodontics.
Health conditions like severe heart-valve disease, uncontrolled diabetes or drugs to treat arthritis or osteoporosis can also make tooth movement difficult. And, if you have restricted saliva flow (dry mouth), wearing orthodontic devices could be uncomfortable and increase your risk of tooth decay.
If, however, your mouth and body are reasonably healthy (and you don’t have a difficult bite problem to correct), there’s no reason why you can’t undergo orthodontic treatment. The only other thing that might hold you back is concern over your appearance during treatment. Many adults balk at the possible embarrassment of wearing metal braces “at their age.”
If this is a concern, you may have an alternative: clear aligners. These are a series of computer-generated clear plastic trays that conform to the individual contours of your teeth. Each tray is slightly different—you wear one for a short period of time (usually two weeks) before moving on to the next tray to successively and gradually move your teeth. They’re nearly invisible to others and, unlike fixed metal braces, you can take them out for a rare special occasion.
The only way you’ll know whether correcting your misaligned teeth is a viable option is to undergo a full orthodontic evaluation. From there we can help you decide if and how you want to gain a straighter, more attractive smile.
