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.

Gum disease is a bigger problem than you might think. More than half of all adults over age 30 have it, and that figure jumps to 70% of adults over 65. If left untreated, gum (periodontal) disease can eventually loosen teeth and cause them to fall out. It can also cause health issues outside of the mouth, including an increased risk of heart disease and other systemic health conditions.
But the good news is that gum disease can be treated—and even better, prevented! Since September is National Gum Care Month, it’s a good time to answer some frequently asked questions about gum disease:
What causes gum disease?
Gum disease is caused by certain types of harmful oral bacteria that live in a sticky film called dental plaque that collects on teeth both above and below the gum line. If this film is not cleaned effectively each day, it can eventually harden into a substance called tartar that can only be removed by a dental professional. As your body tries to fight the bacteria and the toxins they produce, your gums can become inflamed and may start to pull away from the teeth. Eventually, bone beneath the gums can start to break down and with continued bone loss, the teeth could be lost.
How do I know if I have it?
Gum disease doesn’t always produce symptoms—especially in smokers. Smoking hides the symptoms of gum disease because nicotine reduces blood flow to the area. However, there are things you should look out for. Gingivitis, a mild form of gum disease, can produce red and/or puffy gums that bleed when you brush or floss. Signs of periodontitis, a more serious form of the disease, include gum recession, bad mouth odors or tastes, and tooth looseness. But the only way to truly know if you have gum disease is to come in for an exam.
What can I do about it?
If you have gingivitis, a professional teeth cleaning and a renewed commitment to oral hygiene at home—including daily flossing and rinsing with antibacterial mouthwash—may be all you need to turn the situation around. Periodontitis may require a variety of treatments, ranging from special cleaning procedures of the tooth root surfaces to gum surgery. The first step toward controlling gum disease is visiting the dental office for an exam.
How can I prevent it?
Regular professional teeth cleanings and meticulous oral hygiene at home are your best defenses against gum disease. Avoid sugary drinks and snacks—which feed the disease-causing bacteria in your mouth—and tobacco in all forms. If you have diabetes, do your best to manage it well because uncontrolled diabetes can worsen periodontal disease.
Periodontal disease may start in the gums’ superficial layers, but it’s not likely to stay there. As the disease moves deeper it can wreak havoc on tooth roots and bone as well as gum tissue attachments. Teeth with multiple roots are in particular peril because of the “forks” called furcations that form where the roots separate from each other. Infected furcations can be very difficult to treat.
We primarily treat gum disease by removing its main source, a thin film of bacteria and food particles called dental plaque that builds up on teeth. To remove it we most often use special hand tools or ultrasonic equipment to vibrate it loose. As the plaque and tartar diminish, the infection begins to wane.
But we can’t be completely successful in stopping the disease if any lingering plaque deposits remain. This especially includes furcations where the infection can cause significant damage to the roots. Although cleaning furcations of plaque can be difficult, it’s not impossible with the aforementioned tools and antimicrobial substances to disinfect the area.
The real problem, though, is access—effectively getting to the furcations to treat them. We may need to perform a surgical procedure called flap surgery where we create a hinged flap in the gum tissue to move it aside and access the root area beneath. Afterward we replace the flap and suture the tissue back in place.
In some cases, the infection may have already caused significant damage to the tissue and underlying bone. We may therefore need to graft gum or bone tissues to these damaged areas to stimulate re-growth. We may also need to surgically reshape the gum attachments around a tooth to make it easier in the future to access and clean the area.
These additional treatments around furcations can be very involved and labor-intensive. That’s why the best outcomes occur if we’re able to start treatment in the early stages of an infection. So, if you notice red, swollen or bleeding gums contact your dentist as soon as possible. Treating gum disease as early as possible will help ensure your tooth roots won’t suffer extensive damage.
