Over the last century effectively treating a decayed tooth has often required removing any decayed structure with drilling and then filling the remaining cavity. While this approach does save teeth that might otherwise be lost, it can also result in a fair amount of healthy structure removed in the process.
But continuing advances in dentistry are now making possible a new approach to tooth decay treatment that preserves as much of the healthy portions of tooth as possible. This new way is often referred to as minimally invasive dentistry (MID).
The primary goal of MID treatment is to intercept and treat decay as early as possible to minimize tooth damage. It begins with helping patients identify their own individual risk factors for decay such as the presence of disease-causing bacteria, the adequacy of their saliva flow, or their lifestyle and dietary habits. We then recommend changes or preventive measures to reduce those risks.
The next step in MID is using various diagnostic technologies to find decay as early as possible. X-rays continue to play a major role, but dentists are also using dental microscopy to magnify the earliest forms of decay. Many also utilize laser fluorescence, infrared photography and optical scanning to further “see” decay difficult to detect with the naked eye.
In regard to treatments, MID adopts the adage “less is more.” If caught early enough, we can encourage the re-mineralization of enamel that acid has eroded with CPP-ACP, a substance acquired from milk, or strengthen teeth with topical fluoride applications. Instead of the dental drill, many dentists now turn to air abrasion for decay removal, equipment that emits a fine stream of abrasive particles that harms less healthy structure than a drill.
And if lasers continue to develop at their current pace, we’ll be able to use this technology to perform much more precise decay treatment than possible with manual instruments. As a result, we’ll be able to treat decayed teeth with less invasive means to preserve as much healthy structure as possible.
As these and other developments continue, MID promises a bright future for preventing and treating tooth decay. As a result, there’ll be less tooth structure loss and more attractive and healthy smiles.

Tooth decay is a destructive disease that could rob you of your teeth. But it doesn't appear out of nowhere—a number of factors can make it more likely you'll get cavities.
But the good news is you can be proactive about many of these factors and greatly reduce your risk of tooth decay. Here are a few questions to ask yourself to point you in the right direction for preventing this destructive disease.
Do you brush and floss every day? A daily habit of brushing and flossing removes buildup of dental plaque, a bacterial film on teeth that's the top cause for tooth decay and periodontal (gum) disease. Hit or miss hygiene, though, can greatly increase your risk for developing a cavity.
Do you use fluoride? This naturally occurring chemical has been proven to strengthen tooth enamel against decay. Many locations add fluoride to drinking water—if your area doesn't or you want to boost your fluoride intake, use toothpastes, mouthrinses or other hygiene products containing fluoride.
Do you smoke? The nicotine in tobacco constricts blood vessels in the mouth so that they provide less nutrients and antibodies to the teeth and gums. Your mouth can't fight off infection as well as it could, increasing your risk of dental diseases like tooth decay.
Do you have dry mouth? This isn't the occasional bout of “cotton mouth,” but a chronic condition in which the mouth doesn't produce enough saliva. Saliva neutralizes mouth acid, so less of it increases your risk for decay. Chronic dry mouth can be caused by medications or other underlying conditions.
Do you snack a lot between meals? Sugary snacks, sodas or energy drinks can increase oral bacteria and acidity that foster tooth decay. If you're snacking frequently between meals, your saliva's acid neutralizing efforts may be overwhelmed. Coordinate snacking with mealtimes to boost acid buffering.
You can address many of these questions simply by adopting a daily habit of brushing and flossing, regular dental cleanings and checkups, and eating a healthy, “tooth-friendly” diet. By reducing the risk factors for decay, you can avoid cavities and preserve your teeth.

If you've ever had a run-in with cavities, you know the drill (no pun intended): After getting a local anesthetic for pain, the dentist removes any decayed dental tissue, as well as some healthy tissue, and then fills the cavity to restore the tooth. It's an effective treatment protocol we've been using for well over a century.
It does, however, have its drawbacks. For one, although necessary, removing healthy dental tissue can weaken the overall tooth structure. The dental drill used during the procedure is also unpleasant to many people: Although it doesn't cause any pain thanks to the anesthetic, the sounds and pressure sensations associated with it can be unsettling.
But advances in dental tools, technology and techniques are addressing these drawbacks in traditional tooth decay treatment. In other words, treating a tooth with cavities today is taking on a lighter touch. Here are 3 reasons why.
Earlier detection. The key to effective treatment is to find tooth decay in its earliest stages. By doing so, we can minimize the damage and reduce the extent of treatment needed. To do this, we're beginning to use advanced diagnostic tools including digital x-rays, intraoral cameras and laser fluorescence to spot decay, often before it's visible to the naked eye.
Re-mineralizing enamel. One of the advantages of early detection is to catch tooth enamel just as it's undergoing loss of its mineral content (demineralization) due to contact with acid. At this stage, a tooth is on the verge of developing a cavity. But we can use minimally invasive measures like topically applied fluoride and CPP-ACP (a milk-based product) that stimulates enamel re-mineralization to prevent cavity formation.
Less invasive treatment. If we do encounter cavities, we no longer need to turn automatically to the dental drill. Air abrasion, the use of fine substance particles under high pressure, can precisely remove decayed material with less loss of healthy tissue than a dental drill. We're also using newer filling materials like composite resins that don't require enlarging cavities as much to accommodate them.
These and other techniques—including laser technology—are providing superior treatment of tooth decay with less invasiveness. They can also make for a more pleasant experience when next you're in the dentist's chair.
