Dental veneers are a popular way to improve teeth with chips, stains, gaps or other defects. They're typically made of dental porcelain, ceramic-like materials prized for their ability to mimic the texture, color and translucency of natural teeth.
But dental porcelain doesn't come in one form—a dentist can utilize variations of it to better match a patient's need. For example, one patient may need a porcelain with added strength, while another may need one that provides better coverage of underlying discoloration.
The foundational materials for veneer porcelain are glass ceramics. Also used for crowns, glass ceramics have been the preferred choice of dentists for some time to achieve life-like results. In terms of veneers, dental technicians first mix the powdered form of the porcelain with water to create a paste. They then use the paste to build up the body of a veneer layer by layer.
But while the high degree of silica (glass) in this type of porcelain best resembles the translucence of natural teeth, early forms of it lacked strength. This changed in the 1990s when technicians began adding a material called leucite to the ceramic mixture that enhanced its strength and durability.
Today, you'll also find lithium disilicate used, which is twice as strong as leucite and is quite useful when creating thinner veneers. Both of these strength materials can be pressed and milled into shape, which helps achieve a more accurate fit. Along with the underlying glass ceramic, the result is a veneer that's both durable and incredibly life-like.
Although today's porcelain veneers are far superior in durability than earlier forms, they can be damaged when biting down on hard objects. To make sure your veneers last as long as possible, you should avoid biting down directly on hard-skinned fruit, or using your veneered teeth to crack nuts or crunch ice (or any other teeth, for that matter).
But with proper care, today's veneers have exceptional longevity. And, thanks to the superior dental materials that compose them, they'll look great for years.

When you see your dentist about mouth pain, you expect to hear that it's a decayed or fractured tooth, or maybe a gum infection. But you might be surprised if your dentist tells you there's nothing going on inside your mouth to cause the pain.
It's not that far-fetched: The pain could be originating elsewhere. This is known as referred pain, where pain radiates from its origin to another part of the body.
Unless there's an obvious oral cause for the pain, it's best not to undertake any treatment involving the mouth until we've pinpointed the actual cause. That said, the cause is usually not too far away.
Facial nerve disorders. The trigeminal nerve courses on either side of the face from the upper skull through the cheeks and ends around the lower jaw. But if portions of the nerve's protective sheathing become damaged, the slightest touch on the face could trigger prolonged pain. Because of its proximity to the jaw, the pain can often be misidentified as a toothache.
Jaw joint pain. When joints connecting the lower jaw to the skull become traumatized and inflamed, a condition known as Temporomandibular joint disorder (TMD), the pain can radiate toward the jaw. In some cases, the person may easily mistake the muscle pain and spasming for a toothache.
Ear infection. As with TMD, your "toothache" may actually stem from an ear infection or congestion radiating pain into the jaw. It can also happen in the opposite direction—ear pain could actually be the referred pain of an infected back tooth—emphasizing the importance of precisely determining the originating source of any pain in the jaws or face.
Sinus pain. The large maxillary sinuses are located on either side of the face just above the back of the upper jaw. Because of its proximity, pain from a sinus infection can seem to be coming from one of the back molars. And as with ear infections, frequent sinus infections could in fact be caused by an infected tooth penetrating through the sinus floor.
These and other examples of possible referred pain illustrate how "tricky" a presumed toothache can be. Finding the true source of oral or facial pain will ensure you receive the proper treatment for lasting relief.
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.
