The basics for treating tooth decay have changed little since the father of modern dentistry Dr. G.V. Black developed them in the early 20th Century. Even though technical advances have streamlined treatment, our objectives are the same: remove any decayed material, prepare the cavity and then fill it.
This approach has endured because it works—dentists practicing it have preserved billions of teeth. But it has had one principle drawback: we often lose healthy tooth structure while removing decay. Although we preserve the tooth, its overall structure may be weaker.
But thanks to recent diagnostic and treatment advances we’re now preserving more of the tooth structure during treatment than ever before. On the diagnostic front enhanced x-ray technology and new magnification techniques are helping us find decay earlier when there’s less damaged material to remove and less risk to healthy structure.
Treating cavities has likewise improved with the increased use of air abrasion, an alternative to drilling. Emitting a concentrated stream of fine abrasive particles, air abrasion is mostly limited to treating small cavities. Even so, dentists using it say they’re removing less healthy tooth structure than with drilling.
While these current advances have already had a noticeable impact on decay treatment, there’s more to come. One in particular could dwarf every other advance with its impact: a tooth repairing itself through dentin regeneration.
This futuristic idea stems from a discovery by researchers at King’s College, London experimenting with Tideglusib, a medication for treating Alzheimer’s disease. The researchers placed tiny sponges soaked with the drug into holes drilled into mouse teeth. After a few weeks the holes had filled with dentin, produced by the teeth themselves.
Dentin regeneration isn’t new, but methods to date haven’t been able to produce enough dentin to repair a typical cavity. Tideglusib has proven more promising, and it’s already being used in clinical trials. If its development continues to progress, patients’ teeth may one day repair their own cavities without a filling.
Dr. Black’s enduring concepts continue to define tooth decay treatment. But developments now and on the horizon are transforming how we treat this disease in ways the father of modern dentistry couldn’t imagine.
While tooth decay seems to get most of the “media attention,” there’s another oral infection just as common and destructive: periodontal (gum) disease. In fact, nearly half of adults over 30 have some form of it.
And like tooth decay, it begins with bacteria: while most are benign or even beneficial, a few strains of these micro-organisms can cause gum disease. They thrive and multiply in a thin, sticky film of food particles on tooth surfaces called plaque. Though not always apparent early on, you may notice symptoms like swollen, reddened or bleeding gums.
The real threat, though, is that untreated gum disease will advance deeper below the gum line, infecting the connective gum tissues, tooth roots and supporting bone. If it’s not stopped, affected teeth can lose support from these structures and become loose or out of position. Ultimately, you could lose them.
We can stop this disease by removing accumulated plaque and calculus (calcified plaque, also known as tartar) from the teeth, which continues to feed the infection. To reach plaque deposits deep below the gum line, we may need to surgically access them through the gums. Even without surgery, it may still take several cleaning sessions to remove all of the plaque and calculus found.
These treatments are effective for stopping gum disease and allowing the gums to heal. But there’s a better way: preventing gum disease before it begins through daily oral hygiene. In most cases, plaque builds up due to a lack of brushing and flossing. It takes only a few days without practicing these important hygiene tasks for early gingivitis to set in.
You should also visit the dentist at least twice a year for professional cleanings and checkups. A dental cleaning removes plaque and calculus from difficult to reach places. Your dentist also uses the visit to evaluate how well you’re doing with your hygiene efforts, and offer advice on how you can improve.
Like tooth decay, gum disease can rob you of your dental health. But it can be stopped—both you and your dentist can keep this infection from ruining your smile.
