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.
You've no doubt heard about certain foods and beverages that increase your risk for dental disease. These foods, often high in added sugar or acid, can lead to tooth decay or periodontal (gum) disease.
But have you heard about foods with the opposite effect — actually protecting your teeth against disease? Many of these dental-friendly foods are plant-based and fibrous: they stimulate saliva production, one of the mouth's best disease-fighting weapons.
But there are also some foods you might not expect to make the good list for dental health. Here are 3 surprising foods that could help you fight dental disease.
Cheese. We've long recognized milk as important to dental health — but cultured dairy products like cheese are also good for teeth. Cheese stimulates saliva, which neutralizes acid and replenishes the enamel's mineral content. Cheese also contains decay-stopping minerals like calcium, phosphorous and casein. And although milk cheese contains the sugar lactose, this particular type triggers less acid production than other sugars.
Black & green teas. You may have heard about the staining effect of tea, and avoided it as a result. But both forms of tea are also rich in antioxidants, substances that protect us against disease, including in the mouth. Black tea also contains fluoride, which strengthens enamel against cavities. If you drink tea, of course, you should exercise diligent hygiene to reduce any staining effect.
Chocolate. Yes, you read that right, chocolate: unrefined cocoa to be exact, which contains a number of compounds that resist decay. Ah, but there's a catch — chocolate in the form of your favorite candy bar usually contains high amounts of sugar. Sweetened chocolate, then, is a mixed bag of decay-resistive compounds and decay-promoting sugar. To get the benefit you'll have to partake of this favorite food of the Aztecs in a more raw, less sweetened form.
Of course, there's no single wonder food that prevents tooth decay. Your best approach is a diet rich in fresh fruits and vegetables, dairy and quality protein while limiting sugar-added and acidic foods.Â And don't forget daily brushing and flossing, coupled with regular dental visits for cleanings and checkups. Having a comprehensive dental care plan will help ensure your teeth remain healthy and disease-free.

Protecting a child's primary (“baby”) teeth from tooth decay should be a top priority. If one is lost prematurely due to decay, it could cause the permanent tooth to misalign when it comes in.
The basic prevention strategy for every child is daily brushing and flossing and regular dental visits. But children at higher risk for decay may need more: Â additional fluoride applied to teeth enamel during office visits.
This natural mineral has been shown to strengthen enamel, teeth's protective layer against decay, especially during its early development. Enamel is composed of calcium and phosphate minerals interwoven to form a crystalline structure called hydroxyapatite. Fluoride joins with this structure and changes it to fluorapatite, which is more resistant to mouth acid than the original structure.
We mostly receive fluoride through fluoridated drinking water and dental care products like toothpaste. Topical fluoride takes it a step further with a stronger dose than found in either of these sources. It can be applied with a foam, varnish or gel using an isolation tray (foam or gel) or painted onto the enamel (varnish or gel).
But does topical fluoride effectively reduce the occurrence of decay? Research indicates yes: a recent review of 28 studies involving over 9,000 children found an average 28% reduction in decayed teeth in children who underwent topical fluoride treatments.
There is, though, one potential side effect: children who swallow the fluoride substance can become sick and experience headache, stomach pain or vomiting. This can be avoided with proper precautions when applying it; the American Dental Association also recommends using only varnish for children younger than 6 years. It's also recommended that children receiving gel or foam not eat or drink at least thirty minutes after the treatment (those who receive the varnish aren't restricted in this way).
Topical fluoride is most effective as part of an overall prevention strategy. Besides daily hygiene and regular dental visits, you can also help reduce your child's decay risk by limiting the amount of sugar in their diet. Sealants, which are applied to the nooks and grooves of teeth where plaque can build up, may also help.
