The primary goal of dental care is to preserve teeth. But there are circumstances in which removing a tooth, even a relatively healthy one, could prove best in the long run.
A malocclusion (poor bite) related to crowding might fit such a circumstance. Crowding occurs when the size of the jaw is too small for the teeth coming in. With not enough space, some teeth could erupt out of their proper positions. Removing certain teeth frees up space to eventually allow braces or other orthodontic devices to re-align the teeth.
The teeth most frequently removed are the first bicuspids, located between the cuspid (the "eyeteeth" directly under the eyes) and the back teeth, and the second premolar. Removing these won't normally affect appearance or functionality once orthodontic or cosmetic treatments are complete.
Because of the mechanics of jaw development it might be necessary to perform these extractions several years before orthodontic treatment. This could create another potential problem: the time lag could adversely affect bone health.
This is because bone, as living tissue, has a life cycle with cells forming, functioning and then dissolving, and new cells taking their place. When teeth are chewing or in contact with each other they generate force that travels through the tooth roots to the bone and stimulates cell growth at a healthy replacement rate.
But when a tooth is missing, so is this stimulation. This slows the replacement rate and eventually leads to decreased bone volume. Too much bone loss could create obstacles for orthodontic treatment or a future dental implant.
To avoid this, the dentist will often place a bone graft with processed bone mineral within the empty tooth socket right after extraction. The graft serves as a scaffold for bone cells to grow upon. The graft (plus any other added growth boosters) can help maintain a healthy level of bone volume to facilitate future orthodontic or restorative treatments.
Since targeted extraction for orthodontics is time-sensitive, you should have your child's bite evaluated by an orthodontist by age 7 to see if any action is necessary. The earlier a malocclusion is detected, the more likely a more attractive and healthy smile will be the ultimate outcome.

Your smile isn’t the same without healthy gums—neither are your teeth, for that matter. So, maintaining your gums by protecting them from periodontal (gum) disease is a top priority.
Gum disease is caused by bacterial plaque, a thin biofilm that collects on teeth and is not removed due to poor oral hygiene practices. Infected gums become chronically inflamed and begin to weaken, ultimately losing their firm attachment to the teeth. This can result in increasing voids called periodontal pockets that fill with infection. The gums can also shrink back (recede), exposing the tooth roots to further infection.
Although gum disease treatment techniques vary, the overall goal is the same: remove the bacterial plaque fueling the infection. This most often involves a procedure called scaling with special hand instruments to manually remove plaque and calculus (tartar). If the infection has spread below the gum line we may need to use a procedure called root planing in which we scrape or “plane” plaque and calculus from the root surfaces.
As we remove plaque, the gums become less inflamed. As the inflammation subsides we often discover more plaque and calculus, requiring more treatment sessions. Hopefully, our efforts bring the disease under control and restorative healing to the gums.
But while gum tissue can regenerate on its own, it may need some assistance if the recession was severe. This assistance can be provided through surgical procedures that graft donor tissues to the recession site. There are a number of microsurgical approaches that are all quite intricate to perform, and will usually require a periodontist (a specialist in gum structures) to achieve the most functional and attractive result.
While we have the advanced techniques and equipment to treat and repair gum disease damage, the best approach is to try to prevent the disease from occurring at all. Prevention begins with daily brushing and flossing, and continues with regular dental cleanings and checkups.
And if you do notice potential signs of gum disease like swollen, reddened or bleeding gums, call us promptly for an examination. The sooner we diagnose and begin treatment the less damage this progressive disease can do to your gums—and your smile.
