Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.
Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.
A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.
During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.
Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.
As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.
If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.
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.
A disease happening in one part of your body doesn’t necessarily stay there. Even a localized infection could eventually affect your general health. Periodontal (gum) disease, a bacterial infection that damages gums, teeth and supporting bone, is a case in point.
There’s now growing evidence that gum disease shares links with some other serious systemic diseases. Here are 4 serious health conditions and how gum disease could affect them.
Diabetes. Gum disease could make managing diabetes more difficult—and vice-versa. Chronic inflammation occurs in both conditions, which can then aggravate the other. Diabetics must deal with higher than normal glucose levels, which can also feed oral bacteria and worsen existing gum disease. On the plus side, though, effectively managing both conditions can lessen each one’s health impact.
Heart disease. Gum disease can worsen an existing heart condition and increase the risk of stroke. Researchers have found evidence that chronic inflammation from gum disease could further damage already weakened blood vessels and increase blood clot risks. Treating gum disease aggressively, on the other hand, could lower blood pressure as much as 13 points.
Rheumatoid Arthritis. The increased inflammatory response that accompanies arthritis (and other diseases like lupus or inflammatory bowel disease) can contribute to a higher risk for gum disease. As with the other conditions previously mentioned, chronic inflammation from a gum infection can also aggravate arthritis symptoms. Treating any form of chronic inflammation can ease symptoms in both arthritis and gum disease.
Alzheimer’s disease. The links of Alzheimer’s disease to gum disease are in the numbers: a recent study found people over 70 who’ve had gum disease for ten or more years were 70% more likely to develop dementia than those with healthy gums. There is also evidence that individuals with both Alzheimer’s and gum disease tended to decline more rapidly than those without gum disease.
From the accumulating evidence, researchers now view gum disease as more than an oral problem—it could impact your total health. That’s why you should adopt a disease prevention strategy with daily brushing and flossing and regular dental visits (or whenever you notice puffy, reddened or bleeding gums). Stopping gum disease could provide you a health benefit well beyond preserving your teeth and gums.
