“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.

A woman as gorgeous and funny as Sofia Vergara surely planned to be a model and actress from the get-go, right? Wrong! Sofia’s first career choice actually was to be… a dentist! That’s right, the sexy star of TV’s Modern Family actually was only two semesters shy of finishing a dental degree in her native Columbia when she traded dental school for the small screen. Still, dental health remains a top priority for the actress and her son, Manolo.
“I’m obsessed,” she recently told People magazine. “My son thinks I’m crazy because I make him do a cleaning every three months. I try to bribe the dentist to make him to do it sooner!”
That’s what we call a healthy obsession (teeth-cleaning, not bribery). And while coming in for a professional cleaning every three months may not be necessary for everyone, some people — especially those who are particularly susceptible to gum disease — may benefit from professional cleanings on a three-month schedule. In fact, there is no one-size-fits-all approach to having professional teeth cleanings — but everyone needs this beneficial procedure on a regular basis.
Even if you are meticulous about your daily oral hygiene routine at home, there are plenty of reasons for regular checkups. They include:
- Dental exam. Oral health problems such as tooth decay and gum disease are much easier — and less expensive — to treat in the earliest stages. You may not have symptoms of either disease early on, but we can spot the warning signs and take appropriate preventive or restorative measures.
- Oral cancer screening. Oral cancer is not just a concern of the middle aged and elderly — young adults can be affected as well (even those who do not smoke). The survival rate for this deadly disease goes up tremendously if it is detected quickly, and an oral cancer screening is part of every routine dental visit.
- Professional teeth cleaning. Calcified (hardened) dental plaque (tartar or calculus) can build up near the gum line over time — even if you brush and floss every day. These deposits can irritate your gums and create favorable conditions for tooth decay. You can’t remove tartar by flossing or brushing, but we can clear it away — and leave you with a bright, fresh-feeling smile!
So take a tip from Sofia Vergara, and don’t skimp on professional cleanings and checkups. If you want to know how often you should come in for routine dental checkups, please contact us or schedule an appointment for a consultation.

One of the most widely used forms of dental imaging is the bitewing x-ray. So called because of the shape of the device that holds the exposable film a patient clenches between their back teeth, the bitewing x-ray is an effective means for detecting the earliest stages of tooth decay.
These early signs are small lesions on a tooth surface caused by mineral loss in the enamel. While we can identify them on front teeth through visual examination or bright lighting, they’re nearly impossible to see on the biting surfaces of back teeth. The bitewing x-ray solves this problem.
During the procedure, a narrow beam of x-rays is directed at the back teeth area. Since X-rays can transmit through solid matter, they pass through the teeth and gums to expose the film attached to the bitewing assembly.
X-rays pass through matter at different rates depending on the density of the tissue — a slower rate for harder tissues like teeth and bone and a faster rate for soft tissues like the gums. As a result, x-rays through teeth expose less of the film and appear as a lighter image than the gums. This difference is so precise even a tooth’s softer dentin appears slighter darker than its harder outer enamel.
This precision helps us identify decay lesions. Because the lesions on the enamel are less dense than the normal enamel, they’ll appear as dark spots. By detecting them at this stage we have a better chance for reversing the effects of decay or at least minimizing damage that’s already occurred.
Because x-rays emit radiation, there’s a natural concern about over-exposure and we go to great lengths to reduce it. Children may undergo a bitewing x-ray twice a year for developing teeth, while adults with healthy teeth are typically x-rayed just once a year. Advances in digital film and other technology have also helped lower the exposure rate.
Today’s standard 4-film bitewing x-ray produces about four days worth of what we receive on average from normal background radiation, so the health risk is quite negligible. The benefit, on the other hand, is much greater — the early detection of tooth decay could ultimately save a tooth.
