Orthodontics can produce an amazing smile transformation. With today’s advanced appliances and techniques even the most difficult malocclusions (bad bites) can be overcome. All of this innovation, however, depends on one basic anatomical fact: though firmly set in the mouth, our teeth can still move.
Teeth are actually held in place by the periodontal ligament, a strong, elastic tissue that attaches to them through tiny collagen fibers on one side of the ligament and to the jawbone with similar fibers on the other side. When pressure is placed against a tooth, the bone on the opposite side of the force begins to dissolve (resorb), allowing the tooth to move. As it moves, new bone is built up behind the tooth, to stabilize it. Orthodontists take advantage of this natural mechanism through orthodontic hardware like braces that applies pressure in the desired direction of movement, while the ligament and bone do the rest.
There is, though, a downside to this process. The teeth, bone and gum tissues can contain a kind of “memory” for the former natural position of the teeth. Over time, the lower front teeth tend to take a gradual migratory movement back towards their original position. Also, as we age the lower front teeth may crowd each other as there is a genetic influence for teeth to move to the midline of the face, causing a pressure that allows the skinny lower front teeth to slip behind each other. As a result of both of these tendencies, corrected teeth may retreat from their new positions.
To stop these tendencies, we use an appliance known as a retainer after braces or other hardware is removed. As the name implies, this appliance “retains” the teeth in their new position. For structural “memory,” the retainer will keep the teeth in their new position until the impulse to return to the old one has faded, about eighteen months. Retainers can also slow or stop the natural genetic influence of movement, but it may mean wearing a retainer for an indefinite period, especially individuals who’ve undergone orthodontic treatment later in life.
The length of time you’ll need to wear a retainer after braces — and what type, whether a removable appliance or one permanently attached — will depend on a number of factors including the type of malocclusion, your individual mouth structure and age. We’ll recommend the best option that ensures the best chance of keeping your teeth in their new position.

You may not be nervous at all about visiting the dentist. But put yourself in a child’s place — a routine dental visit could be an anxious experience for them, and even more so if it involves dental work.
Dental professionals recognize this and go to great lengths to make children’s visits as pleasant as possible. It’s common among pediatric and family dentists to see child-friendly exam rooms and a well-trained staff experienced with interacting with children.
While this helps, some children still struggle with anxiety. Dentists have one other technique that can ease a child’s nervousness: conscious sedation. This technique involves the use of pills, inhaled gas or intravenous drips to help patients relax.
Sedation is different from general anesthesia, which uses drugs to render a patient unconscious so they won’t experience pain. A sedated patient remains in a conscious but relaxed state: they can still breathe independently and, with the most moderate form of oral sedation, be able to respond to touch or verbal instructions.
Oral sedation may also be accompanied by other methods like nitrous oxide gas that also aid with physical discomfort. Many drugs used often have an amnesiac effect — the patient won’t remember details about the procedure, which could contribute to less anxiety in the future.
Typically, a child receives an oral sedative just before the procedure. Most drugs are fast-acting and leave the child’s system quickly afterward.Â A staff member monitors their vital signs (pulse, respirations, blood pressure, etc.) during the procedure and after in recovery. They’ll remain in recovery until their vital signs return to normal levels and then be able to go home. They should stay home the rest of the day under adult supervision, but should be alert enough the next day to return to their normal activities.
Relieving anxiety is an important tool to ensure your child receives the dental care they need. It also creates a positive experience that could encourage a young patient to continue regular dental care when they reach adulthood.

When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.
“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”
The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”
A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.
It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.
So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!
