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.

More than one parent has wakened in the middle of the night to an unnerving sound emanating from their child's bedroom. Although it might seem like something from the latest horror flick is romping around in there, all that racket has a down-to-earth cause: teeth grinding.
Teeth grinding is the involuntary habit of gnashing the teeth together when not engaged in normal functions like eating or speaking. It can occur at any time, but frequently with children while they sleep. Adults may also grind their teeth, but it's more prevalent among children.
While stress seems to be the main reason for adult teeth grinding, many health providers believe the habit in children is most often caused by an overreactive response of the neuromuscular system for chewing, which may be immature. Other conditions like asthma, sleep apnea or drug use may also play a role.
Fortunately, there doesn't appear to be any lasting harm from young children grinding their teeth, although they may encounter problems like headaches, earaches or jaw pain in the short term. Most, though, will outgrow the habit and be no worse for wear.
But if it persists beyond childhood, problems can escalate. Adults run the risk of serious cumulative issues like chronic jaw pain, accelerated tooth wear or tooth fracturing. It's similar to finger sucking, a nearly universal habit among young children that poses no real harm unless it persists later in life.
And as with finger sucking, parents should follow a similar strategy of carefully monitoring their child's teeth grinding. If the habit continues into later childhood or adolescence, or noticeable problems like those mentioned previously begin to appear, it may be time to intervene.
Such intervention may initially include diagnosis and treatment for underlying problems like upper airway obstruction, asthma or stress. For short term protection against dental damage, your dentist can also fashion a custom mouthguard for your child to wear while they sleep. Made of pliable plastic, the guard prevents the teeth from making solid contact with each other during a grinding episode.
Outside of some lost sleep, there's little cause for alarm if your child grinds their teeth. But if it seems to go on longer than it should, you can take action to protect their long-term dental health.

It's normal to have occasional mouth dryness—that "cotton mouth" feeling when you first wake up or after eating a spicy meal. It soon dissipates, though, leaving you no worse for wear other than the memory of an unpleasant sensation.
For some, though, the unpleasant sensation becomes a chronic condition known as xerostomia, in which their mouth feels dry most of the time. And, it can have far-reaching consequences beyond a mere irritation if not treated.
Among the numerous causes for xerostomia, the most common appears to be over-the-counter and prescription medication. An estimated five hundred medications have dry mouth as a potential side-effect, from antihistamines to antidepressants. And because people over 65 are more likely to take medications, they also have a high occurrence of xerostomia.
A person with certain systemic diseases like Parkinson's Disease or undergoing radiation or chemotherapy for cancers of the head and neck may also encounter dry mouth. For example, an autoimmune disease called Sjögren's syndrome, primarily affecting postmenopausal women, can dry out the mouth's mucous membranes.
Chronic dry mouth isn't normal, and often a sign of a health problem that should be examined. And it can lead to more problems with your oral health. Because dry mouth is most likely a reduction in saliva, which helps buffer decay-causing acid and provides antibodies to fight bacteria, having less of this vital fluid can increase your risk for both tooth decay and gum disease.
So, what can you do if you're plagued by persistent dry mouth? If you suspect your medications may be a factor, talk with your doctor about whether one of them may be the underlying cause for your symptoms. You may be able to switch to an alternate medication without dry mouth side-effects.
You can also increase your water intake during the day, including drinking more before and after taking medication. And there are a number of products like the artificial sweetener xylitol found in gums and candies that can boost saliva. Your dentist may also be able to recommend products that increase saliva.
Above all, be sure you keep up daily brushing and flossing, as well as regular dental cleanings. Taking care of chronic dry mouth could help you avoid dental problems later.

There's still much about the underlying nature of chronic jaw joint dysfunction we have yet to unravel. Treating these conditions known as temporomandibular joint disorders (TMDs) may therefore require some experimentation to find what works for each individual patient.
Most TMD therapies are relatively conservative: eating softer foods, taking anti-inflammatory pain relievers or undergoing physical therapy. There have been some surgical techniques tried to relieve jaw pain and dysfunction, but these have so far had mixed results.
Recently, the use of the drug Botox has been promoted for relieving jaw pain, albeit temporarily. Botox contains tiny amounts of botulinum toxin type A, a poisonous substance derived from the bacterium Clostridium botulinum, which can cause muscle paralysis. It's mainly used to cosmetically smooth out small wrinkles around facial features.
Because of these properties, some physicians have proposed Botox for TMD treatment to paralyze the muscles around the jaw to reduce pain and discomfort. While the treatment sounds intriguing, there are a number of reasons to be wary of it if you have TMD.
To begin with, the claims for Botox's success in relieving jaw pain have been mainly anecdotal. On the other hand, findings from randomized, double-blind trials have yet to show any solid evidence that Botox can produce these pain-relieving effects.
But even if it lived up to the claims of TMD pain relief, the effect would eventually fade in a few weeks or months, requiring the patient to repeat the injections. It's possible with multiple Botox injections that the body will develop antibodies to fight the botulinum toxin, causing the treatment to be less effective with subsequent injections.
Of even greater concern are the potential side effects of Botox TMD treatment, ranging from headaches and soreness at the injection site to more serious muscle atrophy and possible facial deformity from repeated injections. There's also evidence for decreased bone density in the jaw, which could have far-reaching consequences for someone with TMD.
The best approach still seems to lie in the more conservative therapies that treat TMD similar to other joint disorders. Finding the right combination of therapies that most benefit you will help you better manage your symptoms.

A few months into wearing braces you may notice your gums are swollen. It's likely you've developed periodontal (gum) disease.
Gum disease is a bacterial infection that usually begins with dental plaque. This thin, accumulated biofilm on teeth is filled with bacteria that cause dental disease. The more of it that remains on your teeth, the higher your risk for a gum infection.
In addition to regular dental cleanings, the best way for a person to reduce their gum disease risk is to remove plaque on a daily basis through brushing and flossing. Unfortunately, wearing braces complicates this: The brackets and wires affixed to your teeth can get in the way of your toothbrush and regular dental floss. As a result, you can easily miss plaque hidden around these bits of hardware.
Aside from gum disease, the braces themselves can irritate your gums. This irritation inflames the gums and may even cause more tissue to grow. Compound this overgrowth with a possible gum infection and it's no wonder your gums are severely swollen.
To lessen the chances of swollen gums with braces, you'll need to beef up your daily hygiene efforts. Simply put, it will typically take more time than normal to thoroughly clean around your braces. A few specialized tools, though, might make it easier.
An interproximal brush with a narrower head than a regular toothbrush is useful for accessing tight places around brackets. And a floss threader or a water flosser (which uses pressurized water to loosen and remove plaque) may help you better maneuver around wires to remove plaque between teeth.
Keeping your teeth clean as possible will certainly help you avoid gum swelling due to disease. But swelling from tissue overgrowth may not be resolved until your braces come off. In severe cases, it may even be necessary to remove the braces to treat the gums before resuming orthodontic treatment.
In any case, be as thorough as possible with your oral hygiene efforts during orthodontics and see your regular dentist for cleanings every six months. When you have completed orthodontic treatment, cleanings every six months are usually recommended. It's the best way to keep your gums healthy while you're wearing braces.
