Although the air we breathe has one destination—the lungs—it can arrive there via two possible routes: through the nose or the mouth. In terms of survival, it matters little through which path air travels—just so it travels one of them!
In terms of health, though, breathing through the nose is more beneficial than through the mouth, and is our default breathing pattern. The nasal passages filter minute noxious particles and allergens. Air passing through these passages also produces nitric oxide, a gaseous substance that relaxes blood vessels and improves blood flow.
On the other hand, chronic mouth breathing during childhood can impact oral health. While breathing through the nose, the tongue rests against the roof of the mouth and thus becomes a mold around which the upper jaw and teeth develop. But mouth breathing places the tongue on the lower teeth, which deprives the upper jaw of support and can lead to an abnormal bite.
So why would people breathe through their mouth more than their nose? Simply put, it's more comfortable to do so. Because breathing is so critical for life, the body takes the path of least resistance to get air to the lungs. If obstructions caused by allergic reactions or swollen tonsils or adenoids are blocking the nasal pathway, the action moves to the mouth.
But chronic mouth breathing can often be treated, especially if addressed in early childhood. This may require the services of an ear, nose and throat specialist (ENT) and possible surgical intervention to correct anatomical obstructions. It's also prudent to have an orthodontist evaluate the bite and institute corrective interventions if it appears a child's jaw development is off-track.
Even after correcting obstructions, though, it may still be difficult for a child to overcome mouth breathing because the body has become habituated to breathing that way. They may need orofacial myofunctional therapy (OMT), which retrains the muscles in the face and mouth to breathe through the nose.
Chronic mouth breathing isn't something to be ignored. Early intervention could prevent future oral and dental problems and help the person regain the overall health benefits for nose breathing.

You could have an unattractive smile because of a chipped tooth or one slightly out of alignment. Or, it could be both of the above, plus some heavy staining to boot. Correcting each flaw individually might require a combination of different methods like orthodontics or porcelain crowns, which can take an extended period of time to complete.
But you may be able to correct numerous smile flaws with just one method—and in no more than a couple of treatment visits. It's called direct veneers.
Unlike regular veneers, direct veneers don't require a dental technician to craft a thin porcelain shell to bond over teeth. Rather, a dentist applies a tooth-colored material called composite resin to the problem teeth and "sculpts" an entirely new look that can correct multiple dental flaws at one time.
The dentist usually begins the process by creating a model ("wax-up") of proposed changes based on physical impressions of the jaw and teeth. Both dentist and patient can study the model and modify it if necessary, when finalizing the treatment plan.
At a subsequent appointment, the dentist prepares the tooth surface for bonding by removing a thin layer of tooth enamel, then shapes the teeth to better accommodate the composite resin. This tooth prep is similar to that done with traditional veneers, so it's permanent—the teeth will require some form of restoration from then on.
After applying an etchant and a bonding agent, the dentist applies the composite resin in small amounts, hardening each layer with a special light before applying the next one. With each subsequent layer, the dentist sculps the composite material to eventually resemble the wax-up model.
After completing the composite application, the dentist then uses hand tools and a dental drill to complete shaping, as well as an abrasive strip between teeth to aid future flossing. After just a few hours, the transformation is complete.
Direct veneers are durable, but not to the same extent as regular veneers or other cosmetic enhancements. They can also pick up stains over time, and may require re-treatment at some point. Still, direct veneers are a cost-effective way to improve the appearance of teeth with multiple flaws that could radically change your smile for the better.
For over three decades, Celine Dion has amazed audiences and fans with her powerful singing voice. Best known for her recording of "My Heart Will Go On," the theme song for the movie Titanic, Dion has amassed global record sales topping 200 million. In her early singing days, though, she struggled with one particular career obstacle: an unattractive smile.
The Canadian-born performer had a number of dental defects including crooked and discolored teeth, and—most prominent of all—abnormally large cuspid or "canine" teeth (located on either side of the four front incisors). They were so noticeable that one Quebec celebrity magazine gave her the unflattering nickname "Canine Dion."
This isn't an unusual problem. Since human canines are already the longest teeth in the mouth, it doesn't take much for them to stand out. Our ancient hunter-gatherer ancestors needed these large, pointed teeth to survive. But with the evolution of agriculture and industry, canine teeth have become gradually smaller—so much so that when they're abnormally large, they don't look right in a smile.
So, what can be done if your canines embarrassingly stand out from the rest? Here are some of the options to consider.
Reduce their size. If your canines are just a tad too long, it may be possible to remove some of the enamel layer in a procedure called contouring. Using this technique, we can reduce a tooth's overall size, which we then re-shape by bonding composite resin to the tooth. It's only a good option, though, if your canines have an ample and healthy layer of enamel.
Repair other teeth. The problem of prominent canine teeth may actually be caused by neighboring teeth. When the teeth next to the canines are crooked, the canines can appear more prominent. Alternatively, other teeth around the canines may be abnormally small. Braces or clear aligners can correct crooked incisors, and applying porcelain veneers to smaller teeth could help normalize their length.
Apply dental crowns. In some instances, we can reduce the canines in size and then bond porcelain crowns to them. This is the option that Dion ultimately chose. The natural teeth are still intact, but the crowning process transforms them into properly proportioned, life-like teeth. There is, however, one caveat: The alteration to these teeth will be permanent, so they will need a crown from then on.
Besides crowning her canine teeth, Dion also underwent other dental work to straighten and whiten her other teeth. As a result, this superstar performer now has a superstar smile to match and so can you if your teeth are less than perfect. These or other cosmetic enhancements can give you the look you truly desire. All it takes is an initial visit with us to start you on the road to a transformed smile.
