For over a century dentists treated tooth decay by removing both diseased portions of the tooth and healthy structure deemed at risk for future decay. In the 1970s, though, a new approach emerged, known as Minimally Invasive Dentistry (MID). This practice protocol attempts to preserve as much of the healthy structure as possible.
Before MID, dentists followed a decay treatment protocol developed in the 19th Century. A part of this became known as extension for prevention calling for dentists to remove healthy structure considered vulnerable to decay. Besides reducing the tooth's volume, this practice also resulted in, by today's standards, larger than necessary fillings.
It was thought that removing this additional material would make it easier to clean bacterial plaque, the source of decay, but later, research showed the practice couldn't guarantee the teeth wouldn't be reinfected.
Since then we've learned a lot more about teeth and have developed new ways to detect decay at earlier stages. X-ray imaging, for example, has transitioned largely from film to digital technology, providing more detailed images at greater magnification. This, along with laser fluorescence and infrared cameras, has made it easier to detect the first tiny stages of decay.
We can also limit tooth decay damage by boosting enamel strength with fluoride applications and sealants or reducing decay-causing bacteria with anti-bacterial rinses. We've also seen advancement in techniques like air abrasion that remove decayed tooth material while leaving more healthy structure intact better than using a traditional dental drill.
Restoring teeth after treatment has also improved. While dental metal amalgam is still used for some fillings, the main choice is now composite resin. These new tooth-colored dental materials require less tooth preparation (and thus less material loss) and bond well to the remaining structure, resulting in a stronger tooth.
Following a MID protocol leads to less intervention and less time in the dentist's chair. It also means preserving more of a natural tooth, an important aim in promoting long-lasting dental health.
It’s hard to avoid stress in the 21st Century. We’re all bombarded with stressors, from work to family — even our smart phones!
The problem really isn’t the stressors themselves but how we respond to them and try to relieve stress. This can often have a negative effect on our health. One example: bruxism, also known as teeth grinding or clenching.
These habits involve the rhythmic or spasmodic clenching, biting or grinding of the teeth, often involuntarily, beyond normal chewing function. It often occurs while we sleep — jaw soreness the next morning is a telltale sign. While there are other causes, stress is one of the most common for adults, bolstered by diet and lifestyle habits like tobacco or drug use, or excessive caffeine and alcohol.
Teeth grinding’s most serious consequence is the potential for dental problems. While teeth normally wear as we age, grinding or clenching habits can accelerate it. Wearing can become so extensive the enamel erodes, possibly leading to fractures or cracks in the tooth.
When dealing with this type of bruxism, we must address the root cause: your relationship to stress. For example, if you use tobacco, consider quitting the habit — not only for your overall health, but to remove it as a stress stimulant. The same goes for cutting back on your consumption of caffeinated or alcoholic drinks.
Adopt an “unwinding” pattern at night before you sleep to better relax: for example, take a warm bath or keep work items or digital media out of the bedroom.Â Many people also report relaxation or stress-relief techniques like meditation, mindfulness or biofeedback helpful.
There’s another useful tool for easing the effects of nighttime teeth grinding: an occlusal guard. This custom-fitted appliance worn while you sleep prevents teeth from making solid contact with each other when you clench them. This can greatly reduce the adverse effects on your teeth while you’re working on other stress coping techniques.
Teeth grinding or clenching can prove harmful over time. The sooner you address this issue with your dentist or physician, the less likely you’ll experience these unwanted consequences.

“Less is more” is a truism for much of life. It’s also an important feature of an emerging approach to treating tooth decay known as minimally invasive dentistry (MID).
MID updates another revolution in dental care that occurred in the early 1900s. Treating decay took a quantum leap thanks to techniques developed by Dr. G. V. Black, considered the father of modern dentistry. Dr. Black’s approach (known as “extension for prevention”) involved not only removing decayed tooth structure, but also adjacent areas deemed vulnerable to decay, which made them easier to clean. On the downside, though, it also created larger than normal fillings.
As the practice prevailed through much of the Twentieth Century another weakness became apparent—the approach could not guarantee a treated tooth would not experience decay again. This became the real impetus toward MID—to find more comprehensive ways to treat decay with as little impact on the tooth structure as possible.
These efforts received a real boost from emerging technology. This was especially true in diagnostics with the rise of new devices like intraoral cameras and techniques like laser fluorescence that can enable dentists to detect decay much earlier. It’s now possible to catch the disease at an earlier stage before substantial damage to the tooth occurs.
MID has also led to new treatments that preserve more of the tooth structure. Traditional drilling is increasingly giving way to air abrasion, the use of a fine particle stream of aluminum oxide, glass beads or baking soda directed precisely at decayed structure and minimizing damage to healthy structure. We’re also using new filling materials like composite resin for restorations after treatment that are strong yet still life-like and attractive.
We also can’t forget the role of the twin daily hygiene practices brushing and flossing to remove bacterial plaque, the main source of dental disease. And regular dental cleanings and checkups round out the MID approach, helping to ensure that decay doesn’t get too far. The end result of this revolutionary approach: your teeth can experience less impact from treatment and remain healthier and more attractive in the long-run.
