According to Forbes Magazine, Kylie Jenner is the world's youngest billionaire at age 22. Daughter of Caitlyn (Bruce) Jenner and Kris Jenner, Kylie is the founder and owner of the highly successful Kylie Cosmetics, and a rising celebrity in her own right. But even this busy CEO couldn't avoid an experience many young people her age go through each year: having her wisdom teeth removed.
At around 10 million removals each year, wisdom teeth extraction is the most common surgical procedure performed by oral surgeons. Also called the third molars, the wisdom teeth are in the back corners of the jaws, top and bottom. Most people have four of them, but some have more, some have fewer, and some never have any. They're typically the last permanent teeth to come in, usually between ages 17 and 25.
And therein lies the problem with wisdom teeth: Many times, they're coming in late on a jaw already crowded with teeth. Their eruption can cause these other teeth to move out of normal alignment, or the wisdom teeth themselves may not fully erupt and remain fully or partially within the gums (a condition called impaction). All of this can have a ripple effect, decreasing dental function and increasing disease risk.
As Kylie Jenner has just experienced, they're often removed when problems with bite or instances of diseases like tooth decay or gum disease begin to show. But not just when problems show: It's also been a common practice to remove them earlier in a kind of “preemptive strike” against dental dysfunction. But this practice of early wisdom teeth extraction has its critics. The main contention is that early extractions aren't really necessary from a medical or dental standpoint, and so patients are unduly exposed to surgical risks. Although negative outcomes are very rare, any surgical procedure carries some risk.
Over the last few years, a kind of middle ground consensus has developed among dentists on how to deal with wisdom teeth in younger patients. What has emerged is a “watch and wait” approach: Don't advise extraction unless there is clear evidence of developing problems. Instead, continue to monitor a young patient's dental development to see that it's progressing normally.
Taking this approach can lead to fewer early wisdom teeth extractions, which are postponed to a later time or even indefinitely. The key is to always do what's best for a patient's current development and future dental health.
Still, removing wisdom teeth remains a sound practice when necessary. Whether for a high school or college student or the CEO of a large company, wisdom teeth extraction can boost overall dental health and development.

For a predictable outcome, a dental implant should be placed as soon as the bone and gum tissues following a tooth extraction have healed. But what happens if the tooth has been missing for months or years? You might then run the risk of not having enough bone to properly place an implant.
This can happen because of a disruption in the growth cycle of living bone tissue. As older bone cells dissolve (resorption), new bone develops to take its place. This is a dynamic process, as the amount and exact location of the new growth is in response to changes in the mouth, particularly from forces generated by the teeth as we chew. If, however, this stimulation transmitted to the bone no longer occurs because the tooth is missing, the bone will tend to dissolve over time.
In fact, within the first year after a tooth loss the associated bone can lose as much as a quarter of its normal width. This is why we typically place bone grafting material in an empty socket at the same time as we extract the tooth. This encourages bone growth during the healing period in anticipation of installing a dental implant or a fixed bridge. If, however, the bone has diminished to less than required for a dental implant, we must then use techniques to encourage new bone growth to support a future implant.
One such technique for restoring bone in the back of the upper jaw is to surgically access the area through the maxillary sinus (a membrane-lined air space within the bone structure of the face) positioned just over the jawbone to place grafting material. During surgery performed usually with local anesthesia, the surgeon accesses the sinus cavity, lifts the tissue membrane up from the sinus floor and applies the grafting material on top of the bone. Eventually, the new bone growth will replace the grafting material.
If successful, the new bone growth will be sufficient to support an implant. Thanks to this renewed growth, you’ll soon be able to enjoy better function and a transformed smile provided by your new implant.

Root canal treatments are the go-to procedures dentists use to treat a tooth with advanced internal decay that has resulted in the pulp (nerve) dying. And for good reason: root canals are responsible for saving millions of teeth that would otherwise be lost.
In the basic root canal procedure, dentists make access into a tooth's interior with a small hole drilled into the crown. They then remove all diseased tissue within the pulp chamber and root canals. These now empty spaces are then filled, and the tooth is sealed and crowned to prevent further infection.
This is usually a straightforward affair, although it can be complicated by an intricate root canal network. In those cases, the skills and microscopic equipment of an endodontist, a specialist in root canals, may be needed to successfully perform the procedure.
But there are also occasional cases where it may be inadvisable to use a conventional root canal procedure to treat an endodontic infection. For example, it may be difficult to retreat a root canal on a restored tooth with a crown and supporting post in place. To do conventional root canal therapy, it would be necessary to take the restoration apart for clear access, which could further weaken or damage the remaining tooth's structure.
In this and similar situations, a dentist might use a different type of procedure called an apicoectomy. Rather than access the source of infection through the tooth's crown, an endodontist approaches the infection through the gums. This is a minor surgical procedure that can be performed with local anesthesia.
Making an incision through the gums at the level of the affected root, the endodontist can then remove any infected tissue around the root, along with a small portion of the root tip. They then place a small filling and, if necessary, grafting material to encourage bone growth around the area. The gums are then sutured in place and the area allowed to heal.
An apicoectomy is another way to attempt saving a tooth that's well on its way to demise. Without it or an attempt at a conventional root canal treatment, you might lose your tooth.
