Dairy foods have played a role in human diets for thousands of years. More than one kid—whether millennia ago on the Mesopotamian plains or today in an American suburb—has been told to drink their milk to grow strong. This is because milk and other dairy products contain vitamins and minerals that are essential for a healthy body, including healthy teeth and gums. In honor of National Dairy Month in June, here are four ways dairy boosts your oral health:
Dental-friendly vitamins, minerals and proteins. Dairy products are an excellent source of many vitamins and minerals that are important for good dental health. They are packed with calcium and phosphorus, two minerals that work together to strengthen tooth enamel. In addition to the vitamins they contain naturally, milk and yogurt are fortified with vitamin D, which aids in calcium and phosphorus absorption; cheese contains a small amount of vitamin D naturally. What's more, dairy proteins have been shown to prevent or reduce the erosion of tooth enamel and strengthen the connective tissues that hold teeth in place.
Lactose: a more tooth-friendly sugar. Sugars like sucrose or high fructose corn syrup, which are routinely added to processed foods, are a primary trigger for tooth decay. This is because certain oral bacteria consume sugar, producing acid as a by-product. The acid weakens tooth enamel, eventually resulting in cavities. Dairy products—at least those without added sugar—are naturally low in sugar, and the sugar they contain, lactose, results in less acid production than other common sugars.
The decay-busting power of cheese. We know that high acidity in the mouth is a major factor in decay development. But cheese is low in acidity, and a quick bite of it right after eating a sugary snack could help raise the mouth's pH out of the danger zone. Cheeses are also rich in calcium, which could help preserve that important mineral's balance in tooth enamel.
Dairy for gum health. A study published in the Journal of Periodontology found that people who regularly consumed dairy products had a lower incidence of gum disease than those who did not. And since gum health is related to the overall health, it's important to do all we can to prevent and manage gum disease.
For those who cannot or choose not to consume dairy products, there are other foods that supply calcium naturally, such as beans, nuts and leafy greens—and many other foods are fortified with calcium, vitamin D and other nutrients. It may be wise to take a multivitamin or calcium with vitamin D as a supplement as well.

Although costly in the beginning, dental implants often turn out to be the least expensive tooth replacement option. That's because their enviable record for longevity often outpaces dentures or bridges. Over the long-term you might spend less for implants than these other restorations.
But even with the high success rate of dental implants (greater than 95% survive the ten-year mark), we can't guarantee they won't fail. And if you're a tobacco smoker, the risk of failure might be even higher. One study, for example, found early implant failures were twice the rate for smokers over non-smokers. Although implant failures overall are low, smoking seems to be a factor in those that do.
There are a number of reasons to account for this. For one thing, inhaled smoke can damage salivary glands, reducing the flow of this important fluid. Saliva helps control bacterial growth and neutralize mouth acid, so without it you're more susceptible to tooth decay or periodontal (gum) disease. Either infection could ultimately weaken implant-supporting bone.
The nicotine in tobacco can also restrict oral blood vessels and lower their ability to supply antibodies and nutrients to the teeth and gums. This slows healing, which could have one particular effect on implant durability.
During the intervening weeks between implant placement and crown attachment, the implant's titanium post attracts bone cells that grow and adhere to its surface. The effects of nicotine on healing, especially right after implant surgery, can interfere with this integration process so that the implant doesn't anchor in the bone as well as it should.
If you're a smoker, you can increase your chances of implant success—and have a healthier mouth overall—by quitting smoking beforehand with the help of a cessation program. Or at the least, consider stopping smoking for one week before implant surgery and for two weeks afterward.
And be sure to brush and floss your teeth daily and visit your dentist regularly to keep your teeth and gums as healthy as possible. Stopping smoking and practicing effective oral hygiene could make a big difference in the success or failure of your implant.

X-ray imaging is such an intricate part of dentistry, we usually don't think twice about it. Without it, though, the fight against dental disease would be much harder.
At the same time, we can't forget that x-rays are a form of electromagnetic radiation that can penetrate human tissue. It's that very quality and the difference in the absorption rate between denser bone and teeth and softer diseased tissue that makes disease diagnosis possible.
But this same penetrative power can potentially harm the tissues it passes through. For that reason when practicing any form of x-ray diagnostics, dentists follow a principle known as ALARA, an acronym for "As Low As Reasonably Achievable." In lay terms ALARA means getting the most benefit from x-rays that we can with the lowest dose and exposure time possible.
While practicing ALARA with x-rays is important for patients of any age, it's especially so for children who are more sensitive to radiological energy given their smaller size and anatomy. We can't use the same settings, dosages or exposure times with them as with an adult.
To protect children, dentists have developed techniques and protocols that lessen their exposure time and rate, while still providing usable images for diagnosing disease. The bitewing is a good example of safe and effective pediatric x-ray imaging.
A bitewing is a plastic device holding exposable film that patients bite down on and hold in their mouth while x-raying. The x-rays pass through the teeth and gums and expose the film behind them on the bitewing. Using a bitewing we can capture a set of two to four radiographs to give us a comprehensive view of the back teeth, while exposing the child less radiation than they normally receive daily from background environmental sources.
This and other advances in equipment and digital imaging greatly reduce the amount of radiation patients receive during x-rays. If, though, you're still concerned about your child's x-ray exposure, talk with your dentist who can explain in more detail the x-ray safety protocols they follow. Just like you, they want your child to be as safe as possible while still benefiting from the diagnostic power of x-rays.
