We've known for decades that fluoride strengthens tooth enamel and lowers the risk for decay. And while adding it to toothpaste and drinking water are the more common ways for getting it into the body, an increasingly popular way—especially for children—is to apply fluoride directly to the teeth.
But is topical fluoride really worth the effort and expense? And, are there any side effects to treating teeth this way?
As to the first question, researchers have performed numerous studies measuring fluoride's effectiveness for preventing tooth decay. The Cochrane Oral Health Research Group recently reviewed studies on topical fluoride applications involving nearly 10,000 children and adolescents between the ages of 2 and 15. The combined average for all the studies showed a 28% reduction in decayed teeth for patients who received topical fluoride compared to those who didn't.
This was especially true for children at high risk for decay: directly applying fluoride gels, foams or varnishes to teeth reduces that risk substantially. But there are also side effects to this application. Fluoride in general has only one known safety concern, a condition known as fluorosis. Too much fluoride over time can cause heavy discoloration of the teeth. This does not affect the health of the teeth, but it can look unattractive and require cosmetic treatment to reduce its effect.
There's little to no risk for fluorosis with the controlled treatments offered by dentists; the fluoride solution remains on the teeth no more than a few minutes. But there is a possible side effect during treatment due to the relatively high dose of fluoride used. If the patient accidentally swallows some of the solution, the concentration of fluoride can cause stomach upset, vomiting or headaches.
Dentists minimize the chances for this by usually using the more difficult to swallow varnish form of topical fluoride on younger patients, and using trays or other barrier devices to isolate the fluoride solution from the rest of the mouth. Under professional supervision, it's rare for an accidental ingestion to occur.
The risks for these side effects are quite low, and the benefits of topical fluoride for reducing the chances for decay can more than outweigh them. Fluoride applications are one of many ways we can protect your child's current and future dental health.

Around 20 million people—mostly women after menopause—take medication to slow the progress of osteoporosis, a debilitating disease that weakens bones. But although effective, some osteoporosis drugs could pose dental issues related to the jawbones.
Osteoporosis causes the natural spaces that lie between the mineral content of bone to grow larger over time. This makes the bone weaker and unable to withstand forces it once could, which significantly increases the risk of fracture. A number of drugs have been developed over time that stop or slow this disease process.
Two of the most prominent osteoporosis drugs are alendronate, known also by its trade name Fosamax, and denosumab or Prolia. While originating from different drug families, alendronate and denosumab work in a similar way by destroying specialized bone cells called osteoclasts that break down worn out bone and help dissolve it. By reducing the number of these cells, more of the older bone that would have been phased out lasts longer.
In actuality this only offers a short-term benefit in controlling osteoporosis. The older bone isn’t renewed but only preserved, and will eventually become fragile and more prone to fracture. After several years the tide turns negatively for the bone’s overall health. It’s also possible, although rare, that the bone simply dies in a condition called osteonecrosis.
The jawbones are especially susceptible to osteonecrosis. Forces generated by chewing normally help stimulate jawbone growth, but the medications in question can inhibit that stimulus. As a result the jawbone can diminish and weaken, making eventual tooth loss a real possibility.
Osteonecrosis is most often triggered by trauma or invasive dental procedures like tooth extractions or oral surgery. For this reason if you’re taking either alendronate and denosumab and are about to undergo a dental procedure other than routine cleaning, filling or crown-work, you should speak to your physician about suspending your medication temporarily. Dentists often recommend a suspension of three to nine months before the procedure and three months afterward.
Some research indicates this won’t worsen your osteoporosis symptoms, especially if you substitute another treatment or fortify your skeletal system with calcium and vitamin D supplements. But taking this temporary measure could help protect your teeth in the long run.

Chronic pain can turn your life upside down. While there are a number of disorders that fit in this category, two of them—fibromyalgia and temporomandibular disorders (TMD)—can disrupt your quality of life to the extreme. And it may be the two conditions have more in common than similar symptoms—according to one study, three-fourths of patients diagnosed with fibromyalgia show symptoms of TMD.
To understand why this is, let’s take a closer look at these two conditions.
Fibromyalgia presents as widespread pain, aching or stiffness in the muscles and joints. Patients may also have general fatigue, sleep problems, mood swings or memory failures. TMD is a group of conditions that often result in pain and impairment of the temporomandibular joints that join the jaw with the skull. TMD can make normal activities like chewing, speaking or even yawning painful and difficult to do.
Researchers are now focusing on what may, if anything, connect these two conditions. Fibromyalgia is now believed to be an impairment of the central nervous system within the brain rather than a problem with individual nerves. One theory holds that the body has imbalances in its neurotransmitters, which interfere with the brain’s pain processing.
Researchers have also found fibromyalgia patients with TMD have an increased sensitivity overall than those without the conditions. In the end, it may be influenced by genetics as more women than men are prone to have either of the conditions.
Treating these conditions is a matter of management. Although invasive techniques like jaw surgery for TMD are possible, the results (which are permanent) have been inconclusive in their effectiveness for relieving pain. We usually recommend patients try more conservative means first to lessen pain and difficulties, including soft foods, physical therapy, stretching exercises and muscle relaxant medication. Since stress is a major factor in both conditions, learning and practicing relaxation techniques may also be beneficial.
In similar ways, these techniques plus medication or cognitive-behavioral therapy that may influence neurotransmission can also help relieve symptoms of fibromyalgia. Be sure then that you consult with both your physician and dentist caring for both these diseases for the right approach for you to help relieve the effects of these two debilitating conditions.

Gastroesophageal reflux disease (GERD) is a digestive disorder that can lead to a number of serious health problems. One of them, tooth erosion, could ruin your dental health.
Your stomach uses strong acids to break down food during digestion. A ring of muscle just above the stomach called the esophageal sphincter works as a one-way valve to allow food contents into the stomach but prevent acid from traveling back up through the esophagus.
GERD occurs when the esophageal sphincter weakens and starts allowing acid into the esophagus and potentially the mouth. The acid wash can eventually damage the esophageal lining, causing pain, heartburn, ulcers or even pre-cancerous cells.
Acid coming up in the mouth can cause the mouth’s normally neutral pH to slide into the acidic range. Eventually, these high acid levels soften and erode tooth enamel, increasing the risk of decay and tooth loss.
Accelerated erosion is often a sign of GERD—in fact, dentists may sound the first warning that a patient has a gastrointestinal problem. Unfortunately, a lot of damage could have already occurred, so it’s important to take steps to protect your teeth.
If you’ve been diagnosed with GERD, be sure to maintain good oral hygiene practices like brushing or flossing, especially using fluoride toothpaste to strengthen enamel. But try not to brush right after you eat or during a GERD episode: your teeth can be in a softened condition and you may actually brush away tiny particles of mineral. Instead, wait about an hour after eating or after symptoms die down.
In the meantime, try to stimulate saliva production for better acid neutralization by chewing xylitol gum or using a saliva booster. You can also lower mouth acid by rinsing with a cup of water with a half teaspoon of baking soda dissolved in or chewing on an antacid tablet.
You can also minimize GERD symptoms with medication, as well as avoiding alcohol, caffeine or spicy and acidic foods. Try eating smaller meals, finishing at least three hours before bedtime, and avoid lying down immediately after eating. Quitting smoking and losing weight may also minimize GERD symptoms.
GERD definitely has the potential to harm your teeth. But keeping the condition under control will minimize that threat and benefit your health overall.

November is National Diabetes Month—a time to focus on a disease that affects more than 400 million people around the world. What does diabetes have to do with oral health? Plenty! Here's a true-or-false quiz to test your knowledge on this important topic.
TRUE OR FALSE:
1. Diabetes and gum disease are connected.
TRUE. Studies have found a clear association between diabetes and gum (periodontal) disease, especially when diabetes is not well controlled. People with poorly controlled diabetes have a more severe inflammatory response to the bacteria that cause gum disease. While inflammation is normally a protective reaction of the body's immune system, too much inflammation can actually make the condition worse. In the case of gum disease, the reverse is also true: Untreated gum disease can worsen blood sugar levels in people with diabetes. The good news is that treatment of periodontal disease has been shown to improve blood sugar control.
2. People with diabetes can't have dental implants.
FALSE. Research has shown that dental implants can be a very successful tooth-replacement treatment for people with diabetes. But again, blood sugar control can be a factor. Dental implants are titanium posts that serve as artificial tooth roots. Minor surgery is required to insert an implant into the bone beneath the gums; a realistic-looking dental crown is later attached to it so it can look and function like a natural tooth. Studies have shown that it takes longer for the bone to heal around implants in people with poorly controlled diabetes. That doesn't make implant treatment impossible, but it does mean that it may be managed differently. For example, an implant may be allowed to heal for a longer period of time before a crown is attached to it.
3. People with diabetes can't do anything to improve their oral health.
FALSE. People with diabetes can have a very positive impact on their oral heath, by doing their best to control blood sugar levels with a healthy diet and exercise, and by sticking to an effective daily oral hygiene routine. This includes brushing twice a day for two minutes each time, and flossing at least once each day to remove bacterial plaque between teeth. Regular dental checkups and cleanings are also essential—not just for people with diabetes, but for everyone!
