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.
Fluoride is a critical weapon in the war against tooth decay. But this natural chemical proven to strengthen tooth enamel has also aroused suspicion over the years that it might cause health problems.
These suspicions have led to rigorous testing of fluoride's safety. And the verdict from decades of research? We've found only one verifiable side effect, a condition called enamel fluorosis. Caused by too much fluoride present in the body, enamel fluorosis produces white streaks and patches on teeth, and can develop into darker staining and pitting in extreme cases. But other than having an unattractive appearance, the teeth remain sound and healthy.
Fortunately, you can reduce the risk of fluorosis by limiting fluoride exposure to within recommended limits. Fluoride can show up in processed foods and other substances, but the two sources you should focus on most are oral hygiene products and fluoridated drinking water.
Dentists highly recommend using toothpaste with fluoride to fight tooth decay. But be careful how much your family uses, especially younger members. An infant only needs a slight smear of toothpaste on their brush for effective hygiene. At around age 2, you can increase the amount to about the size of a vegetable pea.
As to drinking water, most utilities add fluoride to their supply. If yours does, you can find out how much they add by calling them or visiting cdc.gov ("My Water's Fluoride"), where you can also learn more about recommended levels of fluoridation. If you think it's excessive, you can switch to water labeled "de-ionized," "purified," "demineralized," or "distilled," which contain little to no added fluoride.
Even if your fluoridated water is within recommended levels, you may wish to take extra precautions for infants nursing with formula. If possible, use "ready-to-feed" formula, which usually contains very low amounts of fluoride if any. If you're using the powdered form, use only water with the aforementioned labeling for mixing.
Before making any drastic changes that might affect your family's fluoride intake, consult with your dentist first. And be sure you're keeping up regular dental visits—your dentist may be able to detect any early signs of fluorosis before it becomes a bigger problem.

While dental diseases tend to be a greater concern as we get older, they also pose a potential threat to children. A particular type of tooth decay called early childhood caries (ECC) can severely damage children's unprotected teeth and skew their normal dental development.
Fortunately, you can protect your child's teeth from disease with a few simple practices. First and foremost: start a hygiene habit as soon as possible to remove disease-causing bacterial plaque. You don't have to wait until teeth appear, either: simply wipe the baby's gums with a clean wet cloth after nursing to minimize the growth of oral bacteria.
When their teeth do begin to erupt, you can switch to brushing (you can add flossing as more teeth erupt—but until the child shows appropriate dexterity, you'll need to do it for them). For infants, brush gently but thoroughly with a soft-bristled brush and a smear of fluoride toothpaste. When they grow older you can increase the toothpaste to a pea-sized amount. And as soon as you can, get them involved with learning to perform these vital habits on their own.
You should also limit your child's consumption of sugar. Our favorite carbohydrate is also a favorite of bacteria, who consume any remnants in dental plaque as a primary food source. So, keep sugary snacks and foods to a minimum and limit them mainly to mealtimes. And don't put a baby to sleep with a bottle filled with a liquid containing sugar (including formula and breastmilk).
Finally, begin taking your child to the dentist regularly by their first birthday for routine cleanings and checkups. Besides removing any hard to reach plaque, your dentist may also apply sealants and topical fluoride to help protect and strengthen tooth enamel. Regular visits make it more likely to detect the early signs of decay, before it does extensive damage. And beginning early makes it less likely your child will develop a fear of dental visits that could carry on into adulthood.
These and other steps will go a long way in protecting your child's teeth and gums so they develop normally. A little prevention and protection will help ensure a happy, healthy smile later in life.
