Each year millions of people endure repeated episodes of congestion, coughing and headaches, all the miseries that come with a sinus infection. Although it seems like all the action is occurring around the nose and upper face, the actual cause could be emanating from somewhere else—your teeth.
It can all begin with decay forming a small cavity in one of the upper back teeth. If it isn't caught and treated early, the decay can spread into the tooth pulp and root canals, tiny passageways to the root and bone. This may or may not cause a severe toothache or sensitivity as the tooth's nerves respond to the infection. These nerves, though, most often eventually die and the pain, if present, will subside—but not the infection.
Left untreated, the infection may then advance into the bone around the root tip, breaking it down and giving bacteria an entryway into the floor of the maxillary sinus that rests just above the upper jaw. Here bacteria can take up residence, occasionally flaring into a sinus infection. This chronic infection could go on for years with allergies mistakenly taking the blame.
If you have frequent bouts of sinusitis, a possible dental connection may be worth investigating. And in the dental profession, there may be no better “detective” for this than an endodontist. Specializing in interior tooth problems and treatments, an endodontist has the diagnostic equipment like CT or 3-D cone beam scanning to accurately image the teeth and upper jaw. With their advanced diagnostics, they're in the best position to uncover hidden tooth decay contributing to sinus problems.
Endodontists are also skilled in treating advanced tooth decay. The main procedure is known as root canal treatment, in which the dentist drills into the tooth's interior to remove infected tissue from the pulp and root canals. They then fill these empty spaces, seal and then crown the tooth for added protection.
After treatment and following up with your physician, you may find your sinus infections are less frequent. And by promptly seeking treatment at the first sign of tooth pain or sensitivity, you might prevent chronic sinusitis from even developing.

Dental crowns are an essential means for restoring damaged or unattractive teeth. A well-crafted crown not only functions well, it looks and blends seamlessly with the rest of the natural teeth.
Crowns are artificial caps that cover an entire visible tooth, often used for heavily decayed or damaged teeth or as added protection after a root canal treatment. Most crowns are produced by a dental lab, but some dentists are now creating them in-office with computer-based milling equipment. On the whole, the various crowns now available function adequately as teeth—but they can vary in their appearance quality.
In the early to mid 20th Century the all-metal crown was the standard; but while durable, it could be less than eye-pleasing. Although more life-like dental porcelain existed at the time, it tended to be brittle and could easily shatter under chewing stress.
Dentists then developed a crown that combined the strength of metal with the attractiveness of porcelain: the porcelain fused to metal or PFM crown. The PFM crown had a hollow, metal substructure that was cemented over the tooth. To this metal base was fused an outer shell of porcelain that gave the crown an attractive finish.
The PFM reigned as the most widely used crown until the mid 2000s. By then improved forms of porcelain reinforced with stronger materials like Lucite had made possible an all-ceramic crown. They’re now the most common crown used today, beautifully life-like yet durable without the need for a metal base.
All-ceramics may be the most common type of crown installed today, but past favorites’ metal and PFM are still available and sometimes used. So depending on the type and location of the tooth and your own expectations, there’s a right crown for you.
However, not all crowns even among all-ceramic have the same level of aesthetic quality or cost—the more life-like, the more expensive. If you have dental insurance, your plan’s benefits might be based on a utilitarian but less attractive crown. You may have to pay more out of pocket for the crown you and your dentist believe is best for you.
Whatever you choose, though, your modern dental crown will do an admirable, functional job. And it can certainly improve your natural tooth’s appearance.
On the way to adulthood, permanent teeth steadily erupt until, if all goes normally, you have a full set of teeth. Sometimes, though, one or more teeth may fail to form. This not only can affect your dental health, but it could also diminish your smile.
For example, if the lateral incisors on either side of the central incisors (the two teeth front and center) don't develop, it could create a smile that's “not quite right.” But we can vastly improve such a smile in one of three unique ways.
The first is to fill the resulting gap through canine substitution. This is an orthodontic method in which we use braces to move the pointed canine teeth, which normally position on the other side of the missing laterals, closer to the central incisors. This choice is determined by the size of the canine teeth. If they are slim in width, they can be re-shaped to make them appear more like a lateral incisor, and the gums possibly reshaped as well around them through cosmetic surgery.
We can also install a dental bridge, an appliance that fills the missing lateral space with prosthetic teeth. A traditional bridge requires the teeth on either side of the gap to be reduced in size, which becomes a permanent alteration to accommodate these crowns. This is a disadvantage in a young person. We can also use a “bonded bridge” which uses adhesives to attach extended pieces (or “wings”) of dental material from either side of the prosthetic tooth to one or more supporting teeth. These wings are behind the permanent teeth. Though not as durable as a traditional bridge, it does avoid altering the support teeth.
Finally, we can replace the missing teeth with dental implants. In this method, we install titanium metal posts into the jawbone at the missing tooth locations and then attach a life-like crown to each one. Implants may be more costly than other restorative methods and can take several months to complete. But they are life-like, highly durable, and don't require any alteration to other teeth. A disadvantage is that you should wait until at least 19 years of age to consider this option. What many people do is use a temporary solution until the proper age to do a dental implant.
Each of these methods have their advantages and disadvantages, which should be thoroughly reviewed in consultation with your dentist. And each may also require other dental work, such as initial orthodontics to open adequate space for a restoration. But any of these methods for correcting a missing lateral tooth can be effective and help restore both a healthier mouth and a more attractive smile.
