Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

While orthodontists can effectively correct most poor bites (malocclusions), some can be quite complex requiring much time and expense. But there's good news—we often don't have to wait on a malocclusion to fully develop if we catch it in time. Thanks to interceptive orthodontics, we may be able to intervene much earlier and eliminate or reduce the degree of difficulty with treatment.
Interceptive orthodontics is a group of techniques and devices used in early childhood to help deter a possible malocclusion. Here are 3 ways this approach could make a difference in your child's bite development.
Guiding jaw growth. On a normal-sized upper jaw, the permanent teeth usually have ample room to erupt. Not so with a smaller jaw: incoming teeth become crowded and may erupt out of alignment or too close to each other. Orthodontists often use a device called a palatal expander to aid an under-sized jaw in its development. The device fits along the roof of the mouth between the teeth and applies gradual outward pressure on them. This encourages the jaw to widen as it grows, thus providing more room for erupting teeth to come in properly and decrease the chances of obstructive sleep apnea in the future.
Reshaping and repositioning jaw bones. An overbite can occur when the jaws aren't properly aligned, often due to poor muscle and bone development. This is where devices like the Herbst appliance are useful. Its hinge mechanism encourages the lower jaw to grow further forward. The jaws can thus develop in a more normal way, minimizing the development of a malocclusion.
Maintaining space. Primary ("baby") teeth are important for dental development because they help guide future permanent teeth to erupt properly; they also keep nearby teeth from drifting into the intended space. But when a primary tooth is lost prematurely due to disease or trauma, the space can become vulnerable to this kind of "drift." With a simple mechanism called a space maintainer we can hold open the space created by a prematurely lost primary tooth until the permanent tooth is ready to erupt.
These and other techniques can help stop bad bites from developing in young children, minimizing or even eliminating the need for future orthodontic treatment. That means a healthier mouth for your child and less impact on your wallet.

A few days before the Oscars, Vanity Fair magazine asked Academy Awards host Neil Patrick Harris to name his most treasured possession. Was it his Tony award statuette for best leading actor in a musical? His star on the Hollywood Walk of Fame? The stethoscope he wore while playing teenaged doctor Doogie Howser on TV? No, as it turns out, the 41-year-old actor’s most treasured possession is… his wisdom teeth. Yes, you read that correctly. “Oddly, I still have my four wisdom teeth,” Harris said. “I refuse to let them go or I’ll lose my wise parts.”
How odd is it for a 41-year-old to have wisdom teeth? Actually, not that odd at all. While it is true that wisdom teeth are often removed, there’s no one-size-fits-all approach to this. It all depends on whether they are causing problems now, or are likely to cause problems in the future.
The trouble wisdom teeth cause is related to the fact that they are the last molars to come in, and that molars are large in size. By the time wisdom teeth appear between the ages of 17 and 21, there often is not enough room for them in the jaw. Sometimes it’s because you may have inherited a jaw size that’s too small for your tooth size; and generally speaking, the size of the human jaw has evolved to become smaller over time.
If room is lacking, the adjacent molar (that came in earlier) can interfere with the path of eruption — causing the wisdom tooth to come in at an odd angle. The wisdom tooth can hit up against that other tooth, possibly causing pain or damaging the adjacent tooth. This is known as “impaction.” Sometimes the wisdom tooth breaks only partway through the gum tissue, leaving a space beneath the gum line that’s almost impossible to clean, causing infection. A serious oral infection can jeopardize the survival of teeth, and even spread to other parts of the body.
If a wisdom tooth is impacted, will you know it? Not necessarily. A tooth can be impacted without causing pain. But we can see the position of your wisdom teeth on a dental x-ray and help you make an informed decision as to whether they should stay or go. If removal is the best course of action, rest assured that this procedure is completely routine and that your comfort and safety is our highest priority. If there is no great risk to keeping them, as Neil Patrick Harris has done, we can simply continue to monitor their condition at your regular dental checkups. It will be particularly important to make sure you are reaching those teeth with your brush and floss, and that you keep to your schedule of regular professional cleanings at the dental office. All healthy teeth are indeed worth treasuring.

We’ve developed a number of effective treatments for periodontal (gum) disease. Depending on how far and deep a patient’s infection has advanced, treatment can be quite invasive and even require surgery. The more invasive, the longer and more uncomfortable the healing process can be.
But using a medical laser could make that less so. Although its use for gum disease treatment is still in its infancy, the latest observations from the field seem to show patients undergoing laser treatment may have less tissue trauma and bleeding, less discomfort after the procedure and quicker healing times.
Gum disease is a bacterial infection mostly caused by dental plaque, a thin film of food particles that build up on teeth in the absence of effective oral hygiene. The infection can advance deep below the gum line, weakening gum attachment to teeth and destroying supporting bone. Ultimately the affected teeth can be lost.
Traditionally, the only way to stop the disease is to manually remove plaque buildup on teeth and gum surfaces, which is continuing to sustain the infection, with special hand instruments called scalers or ultrasonic equipment. Because it’s important to remove as much plaque and diseased tissue as possible, we may need to perform a surgical procedure called flap surgery to move some of the gum tissues out of the way to get to these deeper areas. As with any surgery, this can create tissue trauma that may cause discomfort during the healing process.
Our new alternative is to use an Nd:YAG medical laser in a procedure known as Laser Assisted New Attachment Procedure or LANAP. With light energy delivered through a small fiber no more than the width of three human hairs, the laser can pinpoint diseased tissue and destroy bacteria through intense heat. Because of the laser beam’s tiny width and pulsing action, healthy tissue is at less risk for trauma than with the traditional treatment.
Coupled with other techniques, LANAP procedures could remove as much infected tissue and plaque as traditional methods, but with less healthy tissue trauma. In the future, then, patients with advanced gum disease undergoing laser treatment could have less bleeding and discomfort and faster healing times.

There are instances when a general dentist will remove (extract) a problem tooth. At other times, though, the same dentist may refer a patient needing an extraction to an oral surgeon. Why the difference?
The procedure performed by a general dentist is referred to as a “simple tooth extraction.” “Simple” doesn’t mean easy and requiring no skill or expertise — it certainly does. In this case, the term refers to the anatomy of the tooth being extracted, particularly its roots.
Teeth that respond well in a simple extraction have an uncomplicated root system. The path of removal, usually with a single root involved, is fairly straight and without extreme angles. In the hands of a skilled and experienced dentist, it can be removed with little to no discomfort.
Dentists actually must use finesse to remove a tooth from its socket. The tooth is held in place with tiny collagen fibers that extend from a tough, elastic gum tissue known as the periodontal ligament, which lies between the teeth and the bone. With some manipulation, a dentist can loosen these fibers, which then makes removing the tooth much easier. All of this can usually be performed with local anesthesia.
Of course, to determine if a tooth can be removed this way, we must conduct a thorough dental examination first, including x-ray imaging to determine the exact nature and location of the roots. If the exam reveals the root system is more complex, or that there are defects to the bone or the tooth that could make a simple extraction difficult (resulting, for example, in not removing the crown and root in one piece), then the tooth may need to be removed surgically.
Such situations require the skill and resources of an oral surgeon. These specialists perform a number of surgical procedures related to the mouth and face; as procedures go, extraction is among the most routine. Using local anesthesia and post-operative pain management, undergoing a surgical extraction involves only minimal discomfort and a very short recovery time.
After examining your tooth we’ll recommend the best course for extraction, whether simple or surgical. In either case, we’ll see that your problem tooth is extracted as efficiently and painlessly as possible.
