Each year thousands of people develop sinus infections from various causes. But there's one cause for sinusitis that might surprise you—tooth decay.
Tooth decay begins when the acid produced by oral bacteria erodes a tooth's enamel protection to create a small hole or cavity. Left untreated, the infection can move into the inner pulp of the tooth and tiny passageways leading to the roots called root canals. The decay can then infect and break down the structure of the supporting jawbone.
This could affect the sinus cavities, hollow air-filled spaces in the upper portion of the face. The maxillary sinus in particular sits behind the cheek bones just above the upper jaw. Tooth roots, particularly in back teeth, can extend quite near or even poke through the floor of the maxillary sinus.
If decay affects these roots, the bone beneath this floor may begin to break down and allow the bacterial infection to enter the sinus. We call this particular kind of sinus infection maxillary sinusitis of endodontic origin (MSEO), "endodontic" referring to the interior structure of teeth.
While advanced decay can show symptoms like pain or sensitivity with certain hot or cold foods, it's also possible to have it and not know it directly. But a recurring sinus infection could be an indirect indication that the root of your suffering is a deeply decayed tooth. Treating the sinus infection with antibiotics won't cure this underlying dental problem. For that you'll need to see a dentist or an endodontist, a specialist for interior tooth issues.
The most common way to treat deep tooth decay is with root canal therapy. In this procedure, the dentist enters the decayed tooth's pulp (nerve chamber) and root canals and removes the diseased tissue. They will then fill the empty pulp and root canals with a special filling and seal the tooth to prevent future infection. The procedure stops the infection and saves the tooth—and if you have MSEO, it eliminates the cause of the sinus infection.
So, if you're suffering from chronic sinus infections, you might talk with your dentist about the possibility of a tooth infection. A thorough examination might reveal a decayed tooth in need of treatment.
The American Academy of Pediatrics and other healthcare organizations recommend breastfeeding as the best means for infant feeding. While bottle feeding can supply the nutrition necessary for a baby's healthy development, breastfeeding also provides emotional benefits for both baby and mother.
But there might be an obstacle in a baby's mouth that prevents them from getting a good seal on the mother's breast nipple—a small band of tissue called a frenum. This term describes any tissue that connects a soft part of the mouth like the upper lip or tongue to a more rigid structure like the gums or the floor of the mouth, respectively.
Although a normal part of anatomy, frenums that are too short, thick or inelastic can restrict a baby's lip or tongue movement and prevent an adequate seal while nursing. The baby may adjust by chewing rather than sucking on the nipple. Besides a painful experience for the mother, the baby may still not receive an adequate flow of breast milk.
Bottle-feeding is an option since it may be easier for a baby with abnormal frenums to negotiate during nursing. But the problem might also be alleviated with a minor surgical procedure to snip the frenum tissue and allow more freedom of movement.
Often performed in the office, we would first numb the frenum and surrounding area with a topical anesthetic, sometimes accompanied by injection into the frenum if it's abnormally thick. After the numbing takes effect, we gently expose the tissue and cut it with either surgical scissors or a laser, the latter of which may involve less bleeding and discomfort. The baby should be able to nurse right away.
If you wait later to undergo the procedure, the baby may already have developed compensation habits while nursing. It may then be necessary for a lactation consultant to help you and your baby "re-learn" normal nursing behavior. It's much easier, therefore, to attempt this procedure earlier rather than later to avoid extensive re-training.
While there's little risk, frenum procedures are still minor surgery. You should, therefore, discuss your options completely with your dental provider. Treating an abnormal frenum, though, could be the best way to realize the full benefits of breastfeeding.
After your son or daughter's dental exam, you expect to hear about cavities, poor bites or other dental problems. But your dentist might suggest a different kind of problem you didn't expect—an eating disorder.
It's not a fluke occurrence—a dental exam is a common way bulimia nervosa or anorexia nervosa come to light. That's because the teeth are often damaged by the behaviors of a patient with an eating disorder.
Most of this damage occurs because of purging, the practice of induced vomiting after eating. During vomiting stomach acid can enter the mouth and "wash" against the back of the teeth. After repeated episodes, the acid dissolves the mineral content of tooth enamel and causes it to erode. There's also a tell-tale pattern with eating disorders: because the tongue partially shields the back of the lower teeth while purging, the lower teeth may show less enamel erosion than the upper.
Hygiene practices, both negligent and too aggressive, can accelerate erosion. Anorexics often neglect basic grooming and hygiene like brushing and flossing, which increases the likelihood of dental disease. Bulimia patients, on the other hand, can be fastidious about their hygiene. They're more likely to brush immediately after purging, which can cause tiny bits of the enamel immediately softened by the acid wash to slough off.
In dealing with a family member's eating disorder, you should consider both a short and long-term approach to protect their dental health. In the sort-term the goal is to treat the current damage and minimize the extent of any future harm. In that regard, encourage them to rinse with water (mixed optionally with baking soda to help neutralize acid) after purging, and wait an hour before brushing. This will give saliva in the mouth a chance to fully neutralize any remaining acid. Your dentist may also recommend a sodium fluoride mouth rinse to help strengthen their tooth enamel.
For the long-term, your goal should be to help your loved one overcome this potentially life-threatening condition through counseling and therapy.

The March 27th game started off pretty well for NBA star Kevin Love. His team, the Cleveland Cavaliers, were coming off a 5-game winning streak as they faced the Miami Heat that night. Less than two minutes into the contest, Love charged in for a shot on Heat center Jordan Mickey—but instead of a basket, he got an elbow in the face that sent him to the floor (and out of the game) with an injury to his mouth.
In pictures from the aftermath, Love’s front tooth seemed clearly out of position. According to the Cavs’ official statement, “Love suffered a front tooth subluxation.” But what exactly does that mean, and how serious is his injury?
The dental term “subluxation” refers to one specific type of luxation injury—a situation where a tooth has become loosened or displaced from its proper location. A subluxation is an injury to tooth-supporting structures such as the periodontal ligament: a stretchy network of fibrous tissue that keeps the tooth in its socket. The affected tooth becomes abnormally loose, but as long as the nerves inside the tooth and the underlying bone have not been damaged, it generally has a favorable prognosis.
Treatment of a subluxation injury may involve correcting the tooth’s position immediately and/or stabilizing the tooth—often by temporarily splinting (joining) it to adjacent teeth—and maintaining a soft diet for a few weeks. This gives the injured tissues a chance to heal and helps the ligament regain proper attachment to the tooth. The condition of tooth’s pulp (soft inner tissue) must also be closely monitored; if it becomes infected, root canal treatment may be needed to preserve the tooth.
So while Kevin Love’s dental dilemma might have looked scary in the pictures, with proper care he has a good chance of keeping the tooth. Significantly, Love acknowledged on Twitter that the damage “…could have been so much worse if I wasn’t protected with [a] mouthguard.”
Love’s injury reminds us that whether they’re played at a big arena, a high school gym or an outdoor court, sports like basketball (as well as baseball, football and many others) have a high potential for facial injuries. That’s why all players should wear a mouthguard whenever they’re in the game. Custom-made mouthguards, available for a reasonable cost at the dental office, are the most comfortable to wear, and offer protection that’s superior to the kind available at big-box retailers.
If you have questions about dental injuries or custom-made mouthguards, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “The Field-Side Guide to Dental Injuries” and “Athletic Mouthguards.”
The month of March brings the first day of spring, when nature seems to wake up after a restful winter slumber. It also brings Sleep Awareness Week, which leads us to ask: How's your sleep? For around one of every three people, the answer seems to be: Not so good! In fact, it's estimated that some 50-70 million people in the U.S. alone have sleep problems, including sleep-related breathing disorders like obstructive sleep apnea (OSA).
People who suffer from this condition seem to sleep fitfully and snore loudly—and they may actually wake up dozens of times every night without even knowing it. These "micro-arousals" make it impossible to get restful sleep, which can lead to fatigue, trouble concentrating, and behavioral issues. Children with sleep disorders like OSA are sometimes diagnosed with attention deficit/hyperactivity disorders because the symptoms are very similar.
If you suspect that you (or someone you care about) may have a serious sleep disorder, it's a good idea to get an examination from a medical professional who specializes in this area. If the diagnosis is OSA, there are a number of treatments that can be effective—one of which is an oral appliance that's available from the dental office.
Dentists are quite familiar with the anatomical structure of the mouth, which is sometimes the root cause of OSA. In many individuals, the soft tissue structures in the back of the oral cavity (including the tonsils, tongue and soft palate) can shift position when muscles relax during sleep and block the flow of air through the windpipe. The lack of sufficient air may cause a person to awaken briefly, gasp for breath, and then relax their muscles—over and over again, all night long.
After a complete exam, we can have an appliance custom-made for you that has proven successful in managing mild to moderate cases of OSA. Shaped a little like a retainer, it is worn in your mouth at night and taken out in the daytime. The appliance helps maintain an open airway by re-positioning the jaw and/or keeping the tongue out of the way.
Oral appliance therapy is one of the most conservative options available for treating OSA: It requires no major equipment or irreversible medical procedures. However, there are a number of other options, including machines that supply pressurized air through a face mask and even oral surgery. It's important to consult with a specialist in sleep disorders when you're facing this issue. If the diagnosis is OSA or a similar sleep problem, remember that help may be available here at the dental office.
If you have questions about sleep-related breathing disorders, please contact us or schedule an appointment for a consultation. You can read more in the Dear Doctor magazine articles “Oral Appliances For Sleep Apnea” and “Sleep Disorders & Dentistry.”
