What makes an attractive smile? Of course, shiny, straight and defect-free teeth are a big factor. But there’s another equally important element: all your teeth have come in.
Sometimes, though, they don’t: one or more teeth may remain up in the gums, a condition known as impaction. And if they’re in the front like the upper canines (the pointed teeth on either side of the front four incisors) your smile’s natural balance and symmetry can suffer.
Impaction usually happens due to lack of space on a small jaw. Previously erupted teeth crowd into the space of teeth yet to come in, preventing them from doing so. As a result the latter remain hidden within the gums.
While impaction can interfere with the smile appearance, it can cause health problems too. Impacted teeth are at higher risk for abscesses (localized areas of infection) and can damage the roots of other teeth they may be pressing against. That’s why it’s desirable for both form and function to treat them.
We begin first with an orthodontic examination to fully assess the situation. At some point we’ll want to pinpoint the impacted teeth’s precise location and position. While x-rays are useful for locating impacted teeth, many specialists use cone beam CT (CBCT) technology that produces highly detailed three-dimensional images viewable from different vantage points.
If the tooth is in too extreme a position, it might be best to remove it and later replace it with a dental impact or similar restoration once we’ve completed other necessary orthodontic treatment. But if the tooth is in a reasonable position, we might be able to “move” the tooth into its proper place in the jaw in coordination with these other tooth-movement efforts to make room for it.
To begin this process, an oral surgeon or periodontist surgically exposes the tooth crown (the normally visible portion) through the gums. They then bond a small bracket to the crown and attach a small gold chain. An orthodontist will attach the other end to orthodontic hardware that will exert downward pressure on the tooth to gradually bring it into normal position.
Dealing with impacted teeth of this nature is often part of a comprehensive effort to correct the bite. If we’re successful, it could permanently transform both the smile and overall dental health.

Dentists around the world routinely remove diseased or damaged teeth every day. While some extractions require surgery, many don't: Your family dentist can perform these simple extractions, usually with little complication.
The term simple doesn't necessarily mean easy—as we'll note in a moment, it takes a deft and experienced hand to perform this type of extraction. The term in this case refers more to the type and condition of the tooth: The tooth roots are relatively straight and reside in the bone at an accessible angle. There are otherwise no meaningful impediments to removing it straight out.
The idea of “pulling a tooth” out of the jaw isn't the most accurate way to describe the procedure. A tooth is actually held in place within its bony socket by the periodontal ligament, a tough, elastic tissue between the tooth root and the bone that attaches to both through tiny fibrous extensions. The best method is to first loosen the tooth from the ligament's tiny attachments, for which experienced dentists can develop a certain feel. Once released from the ligament, the tooth will usually come free easily from its socket.
Not all teeth, though, can be removed in this manner. Teeth with multiple roots like back molars, and without a straight trajectory out of the socket, can have a complicated removal. Other dental conditions could also prove problematic for simple extraction, such as brittle roots that might fragment during removal.
For these and other complications, your general dentist may refer you to an oral surgeon for the tooth extraction. But even with the surgical component, these more complicated extractions are relatively minor and routine—millions of wisdom teeth, for example, are removed every year in this manner.
If you have a tooth that needs to be removed due to disease or injury, your dentist will first determine the best way to remove it and will refer you, if necessary, for surgical extraction. And whatever kind of extraction you undergo, the dentist performing it will make sure you remain pain-free during the procedure.
While tooth preservation is usually the best course for long-term dental health, it's sometimes best to remove a tooth. If that should happen, your dentist will make sure it's done with as little discomfort to you as possible.

Holistic medicine aims to provide healthcare for the “whole” person. While it's a worthy approach, the term has also been used to advance ideas, including in dentistry, at odds with solid scientific evidence.
Here are 4 “holistic” oral health claims and why you should be wary of them.
Root canals are dangerous. It might be shocking to learn that some claim this routine tooth-saving procedure increases the risk of disease. The claim comes from an early 20th Century belief that leaving a “dead” organ like a root-canaled tooth in the body damages the immune system. The idea, though, has been thoroughly disproved, most recently by a 2013 oral cancer study that found not only no evidence of increased cancer, but an actual decrease in cancer risk following root canal treatment.
X-rays are hazardous. X-rays have improved tooth decay treatment by allowing dentists to detect it at earlier stages. Even so, many advise avoiding X-rays because, as a form of radiation, high levels could damage health. But dentists take great care when x-raying patients, performing them only as needed and at the lowest possible exposure. In fact, people receive less radiation through dental X-rays than from their normal background environment.
Silver fillings are toxic. Known for their strength and stability, dentists have used silver fillings for generations. But now many people are leery of them because it includes mercury, which has been linked to several health problems. Research concludes that there's no cause for alarm, or any need to remove existing fillings: The type of mercury used in amalgam is different from the toxic kind and doesn't pose a health danger.
Fluoride contributes to disease. Nothing has been more beneficial in dental care or more controversial than fluoride. A proven weapon against tooth decay, fluoride has nonetheless been associated with ailments like cancer or Alzheimer's disease. But numerous studies have failed to find any substantial disease link with fluoride except fluorosis, heavy tooth staining due to excess fluoride. Fluorosis, though, doesn't harm the teeth otherwise and is easily prevented by keeping fluoride consumption within acceptable limits.
Each of these supposed “dangers” plays a prominent role in preventing or minimizing dental disease. If you have a concern, please talk with your dentist to get the true facts about them.
