DontWorryAboutDentalAmalgamItsSafeforTreatingCavities

Dental amalgam—also known as “silver fillings”—has been used for nearly a hundred years to treat cavities. There are several reasons why this mixture of metals has been the go-to material among dentists: Malleable when first applied, dental amalgam sets up into a durable dental filling that can take years of biting forces. What’s more, it’s stable and compatible with living tissue.

But there’s been growing concern in recent years about the safety of dental amalgam, with even some wondering if they should have existing fillings replaced. The reason: liquid mercury.

Mercury makes up a good portion of dental amalgam’s base mixture, to which other metals like silver, tin or copper are added to it in powder form. This forms a putty that can be easily worked into a prepared cavity. And despite the heightened awareness of the metal’s toxicity to humans, it’s still used in dental amalgam.

The reason why is that there are various forms of mercury and not all are toxic. The form making headlines is known as methylmercury, a compound created when mercury from the environment fuses with organic molecules. The compound builds up in the living tissues of animals, particularly large ocean fish, which have accumulated high concentrations passed up through their food chain.

That’s not what’s used in dental amalgam. Dentists instead use a non-toxic, elemental form of mercury that when set up becomes locked within the amalgam and cannot leach out. Based on various studies, treating cavities with it poses no health risks to humans.

This also means there’s no medical reason for having an existing silver fillings removed. Doing so, though, could cause more harm than good because it could further weaken the remaining tooth structure.

The most viable reason for not getting a dental amalgam filling is cosmetic: The metallic appearance of amalgam could detract from your smile. There are newer, more life-like filling options available. Your dentist, though, may still recommend dental amalgam for its strength and compatibility, especially for back teeth. It’s entirely safe to accept this recommendation.

InTodaysNFLOralHygieneTakesCenterStage

Everyone knows that in the game of football, quarterbacks are looked up to as team leaders. That's why we're so pleased to see some NFL QB's setting great examples of… wait for it… excellent oral hygiene.

First, at the 2016 season opener against the Broncos, Cam Newton of the Carolina Panthers was spotted on the bench; in his hands was a strand of dental floss. In between plays, the 2105 MVP was observed giving his hard-to-reach tooth surfaces a good cleaning with the floss.

Later, Buffalo Bills QB Tyrod Taylor was seen on the sideline of a game against the 49ers — with a bottle of mouthwash. Taylor took a swig, swished it around his mouth for a minute, and spit it out. Was he trying to make his breath fresher in the huddle when he called out plays?

Maybe… but in fact, a good mouthrinse can be much more than a short-lived breath freshener.

Cosmetic rinses can leave your breath with a minty taste or pleasant smell — but the sensation is only temporary. And while there's nothing wrong with having good-smelling breath, using a cosmetic mouthwash doesn't improve your oral hygiene — in fact, it can actually mask odors that may indicate a problem, such as tooth decay or gum disease.

Using a therapeutic mouthrinse, however, can actually enhance your oral health. Many commonly available therapeutic rinses contain anti-cariogenic (cavity-fighting) ingredients, such as fluoride; these can help prevent tooth decay and cavity formation by strengthening tooth enamel. Others contain antibacterial ingredients; these can help control the harmful oral bacteria found in plaque — the sticky film that can build up on your teeth in between cleanings. Some antibacterial mouthrinses are available over-the-counter, while others are prescription-only. When used along with brushing and flossing, they can reduce gum disease (gingivitis) and promote good oral health.

So why did Taylor rinse? His coach Rex Ryan later explained that he was cleaning out his mouth after a hard hit, which may have caused some bleeding. Ryan also noted, “He [Taylor] does have the best smelling breath in the league for any quarterback.” The coach didn't explain how he knows that — but never mind. The takeaway is that a cosmetic rinse may be OK for a quick fix — but when it comes to good oral hygiene, using a therapeutic mouthrinse as a part of your daily routine (along with flossing and brushing) can really step up your game.

HavingTroubleFlossingTryUsinganOralIrrigator

Though you don't like to admit it, you don't floss very often. Oh sure, you know it's important to remove the film of bacteria and food particles called plaque that builds up between and on your teeth. And you know you should do it every day.

It's just that, well… you're not very good at using dental floss.

While it's effective, dental floss takes some technique to hold it with your fingers and work it between your teeth. It can be hard for people to get the hang of it — and some aren't physically able or have obstacles like braces that make it harder.

There is a solution: an oral irrigator. Available for home use for decades, these devices deliver pulsating water at high pressure through a handheld device that looks like a power toothbrush. The water flows through a special tip to loosen and flush out plaque from between teeth.

You may have encountered oral irrigation during dental visits. They're a regular part of dental cleanings especially for treatment of periodontal (gum) disease. Because gum tissue weakened by disease may gradually separate from the teeth, large voids or gaps called periodontal pockets can form. These pockets can become further infected and accumulate plaque and calculus (hardened plaque deposits) that can also extend to the roots. Oral irrigation is a way to remove much of the plaque from these hard to reach places.

Oral irrigators have also proven effective for orthodontic patients whose brace hardware inhibits regular dental floss. A 2008 study, for example, found orthodontic patients were able to remove five times as much plaque with an oral irrigator as those who used only a manual toothbrush.

If you're simply looking for an effective alternative to dental floss, an oral irrigator is a good choice. We can help choose the right model for you and give you tips on using it. Your goal is the same as if you were using dental floss — remove the plaque between your teeth to keep disease at bay and your smile healthy.
