You don’t have to be a dental professional to appreciate a beautiful smile. Likewise, you’ll also know when something’s not quite right with one.
Such can be the case when a tooth fails to erupt properly, causing most or all of the crown to remain below the gum line, a condition known as impaction. Upper canines (or “eyeteeth,” for their location in the arch under the eyes) are especially susceptible to impaction: located on either side of the lateral incisors, which are on either side of the central incisors (the two center front teeth).
The upper canines are important both for function and appearance. Working with their lower counterparts they help cut through food as we chew, so you lose some of that efficiency when they don’t erupt properly. Impacted teeth are susceptible to abscesses and cysts, and can impinge upon and damage the roots of other teeth. And just as importantly, their absence also disrupts the smile as nearby teeth tend to move or “drift” toward the open space.
Rather than remove the impacted canines as is often done with back teeth, it may be more advantageous for both function and appearance to “coax” them into full eruption. This requires first pinpointing their exact location below the gums using x-rays or cone beam 3-D imaging.
If the teeth are in reasonably good position we must first prepare them for orthodontic treatment by surgically exposing the crown from the gums and bonding a small bracket to it. We then attach a small gold chain to the bracket that extends outside of the gums when we suture them back into place. The chain is attached to orthodontic hardware that exerts pressure on the impacted tooth for several months to “pull” it out into the arch.
This procedure has the best chance of success if undertaken before the end of jaw development in early adulthood. Otherwise, it may be better to remove the impacted canines and replace them with dental implants, followed by orthodontic treatment of other teeth to restore their proper position and bite relationships. In either case, your impacted upper canines don’t have to be a problem — we can restore both your mouth function and your smile.

Tooth decay and periodontal (gum) disease pose the most common dangers to dental health. But there are some rare conditions that can also place teeth at risk to be on the lookout for during regular dental checkups.
One such condition is root resorption in an adult tooth, in which the root itself or its surface breaks down and is absorbed by the body. Resorption occurs naturally in a primary (“baby”) tooth so it can loosen and give way for an incoming permanent tooth. Â Resorption still occurs in a limited form with young permanent teeth but should eventually stop.
Sometimes, though, it doesn’t, either from the inside of the tooth out (internal resorption) or more often from the outside in, usually around the neck-like (or “cervical”) portion of the tooth. This more common occurrence, External Cervical Resorption (ECR), can first appear as pink spots on the enamel and then progress into cavity-like areas. If not found and treated promptly, damage can occur quickly and lead to tooth loss.
We don’t fully understand the exact nature and causes for ECR, but we have identified risk factors for its development. Excessive orthodontic force on the teeth or any other trauma can cause damage to the periodontal ligament (which holds teeth in place with the jaw bone). Teeth grinding habits and some dental procedures like internal tooth whitening can also be risk factors.That being said, though, the vast majority of people who experience these issues don’t develop ECR.
Although the causes aren’t fully understood, we can still treat it: the key to success is early detection. You probably won’t notice early signs of ECR, but we can often detect spots from routine x-rays. We can then remove the tissue cells within the lesions causing the damage and restore the area with a tooth-colored filling material. If ECR has extended near the tooth’s interior pulp layer, then a root canal treatment may be needed.
Needless to say, the more extensive ECR occurs in the roots, the less likely the tooth can be saved and may need to be extracted. It’s important, therefore, to maintain regular dental checkups (at least twice a year) to increase your chances of catching a developing problem early.

Hollywood superstar Jennifer Lawrence is a highly paid actress, Oscar winner, successful producer and…merry prankster. She's the latter, at least with co-star Liam Hemsworth: It seems Lawrence deliberately ate tuna fish, garlic or other malodorous foods right before their kissing scenes while filming The Hunger Games.
It was all in good fun, of course—and her punked co-star seemed to take it in good humor. In most situations, though, our mouth breath isn't something we take lightly. It can definitely be an unpleasant experience being on the receiving end of halitosis (bad breath). And when we're worried about our own breath, it can cause us to be timid and self-conscious around others.
So, here's what you can do if you're concerned about bad breath (unless you're trying to prank your co-star!).
Brush and floss daily. Bad breath often stems from leftover food particles that form a film on teeth called dental plaque. Add in bacteria, which thrive in plaque, and you have the makings for smelly breath. Thorough brushing and flossing can clear away plaque and the potential breath smell. You should also clean your dentures daily if you wear them to avoid similar breath issues.
Scrape your tongue. Some people can build up a bacterial coating on the back surface of the tongue. This coating may then emit volatile sulfur compounds (VSCs) that give breath that distinct rotten egg smell. You can remove this coating by brushing the tongue surface with your toothbrush or using a tongue scraper (we can show you how).
See your dentist. Some cases of chronic bad breath could be related to oral problems like tooth decay, gum disease or broken dental work. Treating these could help curb your bad breath, as can removing the third molars (wisdom teeth) that are prone to trapped food debris. It's also possible for bad breath to be a symptom of a systemic condition like diabetes that may require medical treatment.
Quit smoking. Tobacco can leave your breath smelly all on its own. But a smoking habit could also dry your mouth, creating the optimum conditions for bacteria to multiply. Besides increasing your disease risk, this can also contribute to chronic bad breath. Better breath is just one of the many benefits of quitting the habit.
We didn't mention mouthrinses, mints or other popular ways to freshen breath. While these can help out in a pinch, they may cover up the real causes of halitosis. Following the above suggestions, especially dental visits to uncover and treat dental problems, could solve your breath problem for good.
