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.

While we often associate tooth decay with cavities forming in a tooth’s visible or biting surfaces, the occurrence of this all too common disease isn’t limited to those areas. Cavities can develop in any part of a tooth exposed to bacteria.
Gum recession, the shrinking back of the gums from the teeth, can cause such exposure in areas normally covered by the gums. Because these areas are usually more vulnerable to infection when exposed, cavities can develop at or right below the gum line. Because of their location it can be difficult to fill them or perform other treatments.
One way to make it less difficult is to perform a crown lengthening procedure. While the term sounds like we’re increasing the size of the tooth, we’re actually surgically altering the gums to access more of the affected tooth surface for treatment. It’s typically performed in a dental office with local anesthesia by a general dentist or a periodontist, a specialist in the gums.
During the procedure, the dentist starts by making small incisions in the gums to create a tissue “flap” that can be lifted out of the way. This exposes the underlying bone, which they then reshape to support the gum tissue once it’s re-situated in its new position. The dentist then sutures the gums back in place. Once the gums heal, the decayed area is ready for treatment.
Crown lengthening is also useful for other situations besides treating cavities. If a tooth has broken off at the gum line, for example, there may not be enough remaining structure to support a crown. Crown lengthening can make more of the underlying tooth available for the crown to “grab” onto. It’s also useful in some cases of “gummy smiles,” in which too much of the gum tissue is visible in proportion to the tooth size.
Because crown lengthening often involves removing some of the bone and is thus irreversible, you should discuss this procedure with your dentist in depth beforehand. It could be, though, this minor procedure might make it easier to preserve your teeth and even make them look more attractive.
The classic movie Willie Wonka & the Chocolate Factory, starring Gene Wilder, still brings back sweet memories of childhood to people everywhere. Recently, the news broke that a remake of the beloved 1971 film is in now development in Hollywood. But at a reunion of the original cast members a few years ago, child star Denise Nickerson revealed that her role as gum-chewing Violet Beauregard caused a problem: she ended up with 13 cavities as a result of having to chew gum constantly during the filming!
It should come as no surprise that indulging in sugary treats can lead to cavities: The sugar in your diet feeds harmful bacteria that can cause tooth decay and other dental problems. Yet lots of kids (not to mention the child inside many adults) still crave the satisfaction that gum, candy and other sweets can bring. Is there any way to enjoy sweet treats and minimize the consequences to your oral health?
First, let’s point out that there are lots of healthy alternatives to sugary snacks. Fresh vegetables, fruits and cheeses are delicious options that are far healthier for you and your kids. Presenting a variety of appealing choices—like colorful cut-up carrots, bite-sized cheese bits and luscious-looking fruits and berries can make it easier (and more fun) to eat healthy foods. And getting kids off the sugar habit is a great way to help them avoid many health problems in the future.
For those who enjoy chewing gum, sugarless gum is a good option. In fact, chewing sugarless gum increases the flow of healthful saliva in the mouth, which can help neutralize the bacteria-produced acids that cause cavities. Gums that have the ADA (American Dental Association) Seal of Acceptance have passed clinical tests for safety and effectiveness.
But if you do allow sugary snacks, there are still a few ways to minimize the potential damage. Restrict the consumption of sweets to around mealtimes, so the mouth isn’t constantly inundated with sugar. Drink plenty of water to encourage saliva flow, and avoid sugary and acidic beverages like soda (even diet soda) and “sports” or “energy” drinks. Brush twice daily with fluoride toothpaste and floss once a day. And don’t forget to visit our office regularly for routine checkups and cleanings. It’s the best way to get a “golden ticket” to good oral health.
