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.
Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

Every May, the National Fibromyalgia & Chronic Pain Association asks people around the world to spread awareness of fibromyalgia and other chronic pain conditions. Anyone with fibromyalgia and its associated joint and muscle pain knows all too well how chronic pain can disrupt everyday life. And as we see frequently in the dental office, people contending with the jaw pain and dysfunction associated with a temporomandibular joint disorder (TMD) can equally relate.
But here’s the kicker—if you’ve been diagnosed with either TMD or fibromyalgia, there’s a good chance you’re also dealing with both conditions. For example, in one recent survey of over a thousand TMD patients, two-thirds reported also having fibromyalgia or similar kinds of health issues. Researchers are looking intently at possible connections between TMD and fibromyalgia since understanding any potential link between the two might open the door to new ways of treatment.
Fibromyalgia patients experience frequent muscle spasms and fatigue throughout their bodies, coupled with other problems like sleeplessness and memory difficulties. Most researchers today believe it’s caused by a malfunction within the central nervous system (CNS) to process pain. Those working with TMD research are also considering whether the same type of malfunction contributes to jaw joint pain and dysfunction.
TMD is an umbrella term for various disorders involving the jaw joints and associated muscles. When you come to the dental office, it is important that we know about any TMD pain you may be experiencing because this can affect your dental visits. For example, people with TMD may have trouble holding their mouth open for an extended period of time, so we can adjust dental exams and treatments accordingly. Also, we will want to look for underlying dental conditions that may have contributed to your TMD.
If you’re experiencing both TMD and fibromyalgia symptoms, be sure you let us as well as your rheumatologist know the various symptoms you’re experiencing with each condition, the treatments you’re undergoing and the medications you’re taking.
For TMD in particular, here are a few things you can do to reduce its impact on your daily life:
- Avoid foods that require heavy chewing or jaw widening;
- Use thermal therapies like warm compresses or ice packs to ease jaw stiffness and pain;
- Practice relaxation techniques to reduce stress in your life;
- Ask about muscle relaxants or other medications that might help.
You may find that some of these practices, particularly stress reduction, are also helpful in managing fibromyalgia. And if there is a deeper connection between TMD and fibromyalgia, unraveling the mystery could hopefully lead to even greater relief for both.
