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.

Implant-supported fixed bridges are growing in popularity because they offer superior support to traditional bridges or dentures. They can also improve bone health thanks to the affinity between bone cells and the implants' titanium posts.
Even so, you'll still need to stay alert to the threat of periodontal (gum) disease. This bacterial infection usually triggered by dental plaque could ultimately infect the underlying bone and cause it to deteriorate. As a result the implants could loosen and cause you to lose your bridgework.
To avoid this you'll need to be as diligent with removing plaque from around your implants as you would with natural teeth. The best means for doing this is to floss around each implant post between the bridgework and the natural gums.
This type of flossing is quite different than with natural teeth where you work the floss in between each tooth. With your bridgework you'll need to thread the floss between it and the gums with the help of a floss threader, a small handheld device with a loop on one end and a stiff flat edge on the other.
To use it you'll first pull off about 18" of dental floss and thread it through the loop. You'll then gently work the sharper end between the gums and bridge from the cheek side toward the tongue. Once through to the tongue side, you'll hold one end of the floss and pull the floss threader away with the other until the floss is now underneath the bridge.
You'll then loop each end of the floss around your fingers on each hand and work the floss up and down the sides of the nearest tooth or implant. You'll then release one hand from the floss and pull the floss out from beneath the bridge. Rethread it in the threader and move to the next section of the bridge and clean those implants.
You can also use other methods like specialized floss with stiffened ends for threading, an oral irrigator (or "water flosser") that emits a pressurized spray of water to loosen plaque, or an interproximal brush that can reach into narrow spaces. If you choose an interproximal brush, however, be sure it's not made with metal wire, which can scratch the implant and create microscopic crevices for plaque.
Use the method you and your dentist think best to keep your implants plaque-free. Doing so will help reduce your risk of a gum infection that could endanger your implant-supported bridgework.

Your risk for periodontal (gum) disease increases if you’re not brushing or flossing effectively. You can also have a higher risk if you’ve inherited thinner gum tissues from your parents. But there’s one other risk factor for gum disease that’s just as significant: if you have a smoking habit.
According to research from the U.S. Centers for Disease Control (CDC), a little more than sixty percent of smokers develop gum disease in their lifetime at double the risk of non-smokers. And it’s not just cigarettes—any form of tobacco use (including smokeless) or even e-cigarettes increases the risk for gum disease.
Smoking alters the oral environment to make it friendlier for disease-causing bacteria. Some chemicals released in tobacco can damage gum tissues, which can cause them to gradually detach from the teeth. This can lead to tooth loss, which smokers are three times more likely to experience than non-smokers.
Smoking may also hide the early signs of gum disease like red, swollen or bleeding gums. But because the nicotine in tobacco restricts the blood supply to gum tissue, the gums of a smoker with gum disease may look healthy. But it’s a camouflage, which could delay prompt treatment that could prevent further damage.
Finally because tobacco can inhibit the body’s production of antibodies to fight infection, smoking may slow the healing process after gum disease treatment. This also means tobacco users have a higher risk of a repeat infection, something known as refractory periodontitis. This can create a cycle of treatment and re-infection that can significantly increase dental care costs.
It doesn’t have to be this way. You can substantially lower your risk of gum disease and its complications by quitting any kind of tobacco habit. As it leaves your system, your body will respond much quicker to heal itself. And quitting will definitely increase your chances of preventing gum disease in the first place.
Quitting, though, can be difficult, so it’s best not to go it alone. Talk with your doctor about ways to kick the habit; you may also benefit from the encouragement of family and friends, as well as support groups of others trying to quit too.

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!

Over the last century effectively treating a decayed tooth has often required removing any decayed structure with drilling and then filling the remaining cavity. While this approach does save teeth that might otherwise be lost, it can also result in a fair amount of healthy structure removed in the process.
But continuing advances in dentistry are now making possible a new approach to tooth decay treatment that preserves as much of the healthy portions of tooth as possible. This new way is often referred to as minimally invasive dentistry (MID).
The primary goal of MID treatment is to intercept and treat decay as early as possible to minimize tooth damage. It begins with helping patients identify their own individual risk factors for decay such as the presence of disease-causing bacteria, the adequacy of their saliva flow, or their lifestyle and dietary habits. We then recommend changes or preventive measures to reduce those risks.
The next step in MID is using various diagnostic technologies to find decay as early as possible. X-rays continue to play a major role, but dentists are also using dental microscopy to magnify the earliest forms of decay. Many also utilize laser fluorescence, infrared photography and optical scanning to further “see” decay difficult to detect with the naked eye.
In regard to treatments, MID adopts the adage “less is more.” If caught early enough, we can encourage the re-mineralization of enamel that acid has eroded with CPP-ACP, a substance acquired from milk, or strengthen teeth with topical fluoride applications. Instead of the dental drill, many dentists now turn to air abrasion for decay removal, equipment that emits a fine stream of abrasive particles that harms less healthy structure than a drill.
And if lasers continue to develop at their current pace, we’ll be able to use this technology to perform much more precise decay treatment than possible with manual instruments. As a result, we’ll be able to treat decayed teeth with less invasive means to preserve as much healthy structure as possible.
As these and other developments continue, MID promises a bright future for preventing and treating tooth decay. As a result, there’ll be less tooth structure loss and more attractive and healthy smiles.
