PlaqueRemovalistheTopPriorityforPreventingorTreatingGumDisease

Tooth loss is often the unfortunate conclusion to a case of untreated periodontal (gum) disease—incentive enough to try either to prevent it or aggressively treat an infection should it occur. In either case, the objective is the same: to remove all plaque from dental surfaces.

Dental plaque (and its hardened form, tartar) is a thin buildup of bacteria and food particles on tooth surfaces. It's a ready food source for sustaining the bacteria that cause gum disease. Removing it can prevent an infection or “starve” one that has already begun.

Your first line of prevention is brushing and flossing your teeth daily to remove any accumulated plaque. Next in line are dental cleanings at least twice a year: This removes plaque and tartar that may have survived your daily hygiene.

Plaque removal is also necessary to stop an infection should it occur. Think of it as a more intense dental cleaning: We use many of the same tools and techniques, including scalers (or curettes) or ultrasonic devices to loosen plaque that is then flushed away. But we must often go deeper, to find and remove plaque deposits below the gums and around tooth roots.

This can be challenging, especially if the infection has already caused damage to these areas. For example, the junctures where tooth roots separate from the main body of the tooth, called furcations, are especially vulnerable to disease.

The results of infection around furcations (known as furcation involvements or furcation invasions) can weaken the tooth's stability. These involvements can begin as a slight groove and ultimately progress to an actual hole that passes from one end to the other (“through and through”).

To stop or attempt to reverse this damage, we must access the roots, sometimes surgically. Once we reach the area, we must remove any plaque deposits and try to stimulate regrowth of gum tissue and attachments around the tooth, as well as new bone to fill in the damage caused by the furcation involvement.

Extensive and aggressive treatment when a furcation involvement occurs—and the earlier, the better—can help save an affected tooth. But the best strategy is preventing gum disease altogether with dedicated oral hygiene and regular dental visits.

FluorideTreatmentsGiveYourChildAddedProtectionAgainstCavities

When it comes to helping your child avoid tooth decay, it's all hands on deck. Tooth decay can not only harm their current set of primary teeth, but the loss of even one tooth could lead to bite problems later on.

And, even if you're doing all the right things—daily brushing and flossing, limiting sugar consumption and regular dental visits—your child might still develop cavities. If so, it may be necessary to add a boost of prevention with topical fluoride applied by your dentist.

With its enamel-strengthening properties, fluoride plays an important role in dental disease prevention. For decades, manufacturers have added fluoride to toothpaste. And, many water utilities now add tiny amounts of fluoride to their drinking supply.

According to a number of studies, these fluoride applications are effective weapons against tooth decay. But direct applications of fluoride to tooth surfaces can provide even greater benefit to children with a higher susceptibility for decay.

Topical fluoride is usually applied by means of a gel, foam or varnish. In varnish form, it's brushed on the teeth, while dentists apply the foam solution within a tray fitted around the teeth. The gel application can be administered by either method.

Although these topical applications use a higher concentration of fluoride than you find in toothpaste, it poses no serious danger to a child's health. But because high doses of fluoride can lead to staining, topical applications are only administered periodically during childhood.

The only short-term health concern is if the child accidentally swallows some of the mixture during application. This can cause symptoms like an upset stomach, vomiting or headache. Dentists, however, take a number of precautions to prevent accidental ingestion in order to avoid these unpleasant side effects.

The benefits, though, appear to well outweigh this minor risk. In a review of several scientific studies involving nearly 10,000 children, there was an average 28% reduction in decayed, missing or filled teeth in those children that underwent topical fluoride treatments.

If you want to know more about topical fluoride treatments and whether they can help your child avoid tooth decay, talk to your dentist. This fluoride booster could help further protect them from this destructive dental disease.
