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.

Parents will do just about anything to relieve their children's discomfort when they're in pain. When a toddler is suffering through a teething episode, it's tempting to turn to a topical numbing ointment to soothe their gums.
But there can be a hidden danger for kids if you use certain over-the-counter products used by adults for gum or teeth pain. Many of these topical ointments contain a pain reliever called benzocaine. While it's relatively safe for adults, benzocaine can be hazardous for infants and young children.
Studies have found that benzocaine contributes to a disease called methemoglobinemia, in which a protein in the blood called methemoglobin increases to abnormal levels. Too much of this protein inhibits the transport of oxygen throughout the body. For young children, this can cause shortness of breath, fatigue and dizziness. In extreme cases, it could lead to seizures, coma or even death.
Parents are urged to avoid using any product containing benzocaine to ease gum or teething pain in children. Instead, the American Academy of Pediatric Dentistry recommends providing a child a chilled (not frozen) teething ring, pacifier or a damp clean cloth to chew on. The chewing action helps relieve gum swelling pressure and the cold will help numb the pain. Massaging the gums with a clean finger may also help.
If the pain persists, parents should consult a doctor or pharmacist about giving their child pain medication. Drugs like ibuprofen or acetaminophen (never aspirin) administered in the proper dosage for a child's age can help ease teething discomfort. Medications should always be given orally—you should never rub substances like aspirin or alcohol directly on the gums, which can further irritate already inflamed tissues.
Teething episodes come and go during a child's early dental development—they are like storms that swell and abate before they finally pass. Except when accompanied by fever or diarrhea, there's no need for concern. Your main goal is to help ease their discomfort as much—and as safely—as possible.
If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.
As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.
Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.
But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.
Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.
So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.
In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.

Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.
Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums. The root in turn fits into a bony socket within the jaw to help hold the tooth in place (along with attached gum ligaments).
A tooth crown is covered by an ultra-hard layer of enamel, which ordinarily protects it from harmful bacteria. But when acid produced by bacteria comes into prolonged contact with enamel, it can soften and erode its mineral content and lead to a cavity.
In contrast to enamel, the roots have a thin layer of material called cementum. Although it offers some protection, it's not at the same performance level as enamel. But roots are also normally covered by the gums, which rounds out their protection.
But what happens when the gums shrink back or recede? This often occurs with gum disease and is more prevalent in older people (and why root cavities are also more common among seniors). The exposed area of the roots with only cementum standing in the way of bacteria and acid becomes more susceptible to cavity formation.
Root cavities can be treated in much the same way as those that occur in the crown. We first remove any decayed tooth structure with a drill and then place a filling. But there's also a scenario in which the cavity is below the gum line: In that case, we may need to gain access to the cavity surgically through the gums.
If you have exposed root areas, we can also treat these with fluoride to strengthen the area against cavity formation. And, as always, prevention is the best treatment: maintain a daily schedule of brushing and flossing and regular dental cleanings to remove bacterial plaque.
Because decay can spread within a tooth, dealing with a root cavity should be done as promptly as possible. But if we diagnose and initiate treatment early, your chances of a good outcome are high.

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.
