Since the late 19th Century, dentists have used established protocols to successfully prevent and treat tooth decay. But there've been changes to this approach the last few years to improve its effectiveness, changes we now refer to as Minimally Invasive Dentistry or MID.
The older approach for treating dental caries (tooth decay) follows the protocols established by Dr. G.V. Black, considered the father of modern dentistry. Black advocated removing not only decayed structure but also some of the healthier but vulnerable portions of a tooth, to avoid further decay and make the tooth easier to clean. This resulted in larger fillings, although they've become smaller as dental techniques have advanced.
MID, on the other hand, aims to remove as little tooth structure as possible while still effectively treating and preventing future decay. To achieve that goal we begin first with a complete assessment of a patient's individual decay risk, known as Caries Management By Risk Assessment (CAMBRA).
With CAMBRA, we're looking at other factors besides individual tooth health: a patient's hygiene, lifestyle and dietary habits; the types and amount of bacteria present; and the quality of saliva flow, needed to neutralize mouth acid. With these the results we develop a customized prevention and treatment strategy.
MID also focuses on detecting dental caries as early as possible. Besides traditional x-rays, we're beginning to use other methods like dental microscopes, laser fluorescence, infrared photography or optical scanning. Early detection leads to early intervention, and with techniques that are much less invasive than the traditional approach.
The new approach also changes how we repair decayed teeth. We're increasingly using air abrasion, a technology that uses fine particles in a pressurized air stream to remove softer decayed tooth material and less healthy structure than the traditional dental drill. We're also using composite resin and other advanced materials for filings: these tooth-colored materials are stronger than previous versions and are quickly taking the place of metal amalgam, requiring less structural removal to accommodate them.
MID's core principles are early disease detection, proactive prevention and treatment with less structural removal. With this enhanced approach to effective dentistry, we're keeping your teeth healthy with minimal discomfort, lower costs and less long-term impact.
Gastroesophageal reflux disease (GERD) is a digestive disorder that can lead to a number of serious health problems. One of them, tooth erosion, could ruin your dental health.
Your stomach uses strong acids to break down food during digestion. A ring of muscle just above the stomach called the esophageal sphincter works as a one-way valve to allow food contents into the stomach but prevent acid from traveling back up through the esophagus.
GERD occurs when the esophageal sphincter weakens and starts allowing acid into the esophagus and potentially the mouth. The acid wash can eventually damage the esophageal lining, causing pain, heartburn, ulcers or even pre-cancerous cells.
Acid coming up in the mouth can cause the mouth’s normally neutral pH to slide into the acidic range. Eventually, these high acid levels soften and erode tooth enamel, increasing the risk of decay and tooth loss.
Accelerated erosion is often a sign of GERD—in fact, dentists may sound the first warning that a patient has a gastrointestinal problem. Unfortunately, a lot of damage could have already occurred, so it’s important to take steps to protect your teeth.
If you’ve been diagnosed with GERD, be sure to maintain good oral hygiene practices like brushing or flossing, especially using fluoride toothpaste to strengthen enamel. But try not to brush right after you eat or during a GERD episode: your teeth can be in a softened condition and you may actually brush away tiny particles of mineral. Instead, wait about an hour after eating or after symptoms die down.
In the meantime, try to stimulate saliva production for better acid neutralization by chewing xylitol gum or using a saliva booster. You can also lower mouth acid by rinsing with a cup of water with a half teaspoon of baking soda dissolved in or chewing on an antacid tablet.
You can also minimize GERD symptoms with medication, as well as avoiding alcohol, caffeine or spicy and acidic foods. Try eating smaller meals, finishing at least three hours before bedtime, and avoid lying down immediately after eating. Quitting smoking and losing weight may also minimize GERD symptoms.
GERD definitely has the potential to harm your teeth. But keeping the condition under control will minimize that threat and benefit your health overall.

Brushing and flossing every day are important for preventing dental disease. The object is to remove as much bacterial plaque, the thin biofilm most responsible for disease, from your teeth and gums as possible.
But how do you know your hygiene efforts are that effective? You can of course do the “tongue test” â?? feel your teeth with your tongue after brushing and flossing and see if they feel smooth and “squeaky” clean. We can also give you a “report card” at your regular cleaning appointment. There is, however, a more precise way you can find out at home by using a plaque disclosing agent.
A plaque disclosing agent is a formulation that when applied to the teeth will temporarily dye any bacterial plaque present a distinct color. While dental hygienists occasionally apply them, they’re also available over the counter for use at home. They’re usually found in a solution, tablet or swab form in various flavors.
To use the product you first brush and floss, then swish the disclosing liquid around in your mouth for about 30 seconds before spitting it out (or chew the tablet or apply the swab as directed). The agent will react with any remaining plaque and dye it a bright color. There are even two-tone agents available that can differentiate between old and new plaque and dye them different colors.
Examining your teeth in a mirror will give you a good idea where you need to concentrate your attention when brushing and flossing. If, for example, you see dyed plaque more along the gum line and less in other places, then that’s where you should focus your hygiene efforts.
While the dye will eventually wear off on its own, you should take the opportunity to brush and floss again to remove any remaining dyed plaque. Not only does this provide a more thorough cleaning at that moment, you’ll also get a better sense of how “thoroughness” feels for future brushing and flossing.
It’s always good to know how well you’re doing with your dental hygiene efforts. A plaque disclosing agent can give you just the right feedback to help you improve.

Oral appliances run the gamut from night guards and retainers to full or partial dentures. Millions of people depend on them for restoring or maintaining dental health.
Today's user-friendly appliances reflect the latest advances in technology. But that doesn't mean you can simply "place them and forget them." Their longevity depends on taking care of them.
The most important aspect of appliance care is keeping them clean. Although bacteria have no effect on an appliance's materials, they can accumulate on its surfaces and raise the risk your natural teeth and gums will be infected. To reduce that risk you should clean your appliance every day.
The best way is with a countertop ultrasonic cleaner. These units emit high frequency sound vibrations that loosen plaque (a thin film of bacteria and food particles) from even the appliance's tiniest crevices. Most units cost between $40 and $60, and pose less of a scratching risk to the appliance's surfaces than manual cleaning.
If you'd prefer to use a brush, there are some dos and don'ts to follow. You can use a cleaner especially designed for your appliance, but less expensive mild dish detergent or hand soap (with an antibacterial agent) will work too. Don't use toothpaste — most contain an abrasive ingredient for removing plaque from enamel that could leave microscopic scratches on your appliance. Use a soft-bristle toothbrush (but not the one you use for your natural teeth) or one designed for your appliance.
While boiling kills bacteria, the high heat can soften and warp the plastic material in an appliance. This could alter how the appliance fits in your mouth, making them loose and uncomfortable to wear. You should also avoid bleach: it can whiten acrylic or nylon designed to mimic the red color of real gum tissue.
Unless we've advised you otherwise, don't wear the appliance around the clock, a practice that raises the chances of bacterial accumulation. And be sure you also brush and floss your natural teeth every day.
Keeping both your mouth and your appliance clean helps ensure the best oral health possible — and that your appliance will last longer.
The CAT scan is a relatively recent technique in dentistry, used to get an image of what’s happening deep within your jaws. You may be wondering what a CAT scan tells us that a conventional x-ray picture does not, and whether it is worth the extra expense to get one. And how does a CAT scan compare with a conventional x-ray in terms of radiation exposure?
CAT stands for “computer assisted tomography.” Often it’s just called a CT scan, for “computerized tomography.” The word “tomography” comes from roots meaning “slice” and “write.” Tomographic techniques take repeated two dimensional pictures, similar to repeatedly slicing through an object, and then assembles them with a computer to produce a three dimensional (3-D) image.
The latest type of CT scan used in dentistry is called CBCT, or Cone Beam Computed Tomography. The Cone Beam refers to a spiral beam of x-rays, which is used to create a series of two dimensional images from which a computer creates a 3-D image. Such an image is of great value in assessing problems and planning treatment.
Here are just a few examples of how a CBCT scan can be used. Orthodontists can see skeletal structures and developing teeth that are still inside the jawbone while planning strategies for directing the teeth in order to arrive at a better bite. Oral surgeons can find impacted or missing teeth, see their locations, and view their proximity to nerves and sinuses, assisting them in planning surgeries. These scans are particularly useful for root canal specialists because they show root canals that are less than a millimeter wide and even reveal accessory canals that may not be visible on conventional x-rays. In cases of sleep disorders such as sleep apnea, a CBCT during sleep can be used to view a person’s airway and how it may be blocked by the tongue and other soft tissues in a person’s throat during sleep.
Compared to background radiation, the amount of radiation delivered in dental x-rays is minimal. A CBCT delivers a dose of radiation that is less than a typical full mouth x-ray series but more than a typical two dimensional panoramic radiograph. Generally CBCT scanners deliver lower doses than medical CT scanners.
With one low-dose CBCT scan, we can get an accurate idea of the internal structure of your bones and teeth and how they are situated in relation to each other. Prior to the availability of such images, many of these relationships had to be discovered in the course of a surgery or other treatment. Thus such a scan can aid greatly in the quality of treatment you will receive.
