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.

As Spring turns to Summer, millions of students will depart high school in the time-honored rite of passage called graduation. At the same time, quite a few of these graduates will be experiencing another maturity milestone: the eruption (coming in) of their last permanent teeth.
Typically, these are the back third molars, better known as “wisdom teeth,” emerging on either end of both the top and bottom jaws sometime between the ages of 18 and 24. Their arrival heralds the end of a long development process that began in infancy.
But this auspicious event can give rise to dental problems. Because they’re the last to come in, wisdom teeth often erupt in an environment crowded by earlier teeth. Depending on jaw size and other factors, there may not be enough room for a normal eruption.
Wisdom teeth can thus erupt out of position, creating a poor bite (malocclusion). Or they might not erupt at all—becoming stuck fully or partially within the gums and bone, a condition known as impaction. Impacted teeth can also cause problems for the adjacent teeth, damaging the roots of the second molars or disrupting the surrounding gum tissue, making them more susceptible to periodontal (gum) disease.
Because of these and other issues, impacted wisdom teeth are among the most common type of teeth removed: an estimated 10 million each year. And many of these are removed before they show signs of disease or complications as a preemptive strike against developing dental problems.
Although unnecessary surgery should always be avoided, according to some research, there’s a one in three chance that erupting wisdom teeth that are not showing signs of trouble will eventually become problematic. And the earlier they’re removed, the lower the risk of post-extraction complications.
Wisdom teeth should always be evaluated on a case by case basis. Those with obvious signs of disease or complications do require prompt treatment, including possible extraction. Others that are asymptomatic can be monitored over time: If they’re tending to become problematic, we can adjust the treatment plan accordingly. Our goal is to ensure these particular teeth signaling the end of childhood won’t detract from dental health in adulthood, so a measured approach seems to be the best and safest one.

While braces are often the stars for straightening smiles, they're not the only cast members in an orthodontic production. Orthodontists occasionally turn to other appliances if the bite problem is challenging. Whatever the tool, though, they usually have something in common—they use the principle of anchorage.
To understand anchorage, let's first consider the classic kid's game Tug of War. With teams on either end of a rope, the object is to pull the opposing team across the center line before they pull you. To maximize your pulling force, the player at the back of your rope, usually your stoutest member, holds steady or "anchors" the rest of the team.
Like a Tug of War team, braces exert force against the teeth. This stimulates the supporting periodontal ligament to remodel itself and allow the teeth to move. The braces use the teeth they are attached to as anchors, which in a lot of cases are the back teeth. By attaching a thin wire to the brackets or braces on the teeth, the orthodontist includes all the teeth on the arch, from one end to the other. Anchored in place, the wire can maintain a constant pressure against the teeth to move them.
But not all bite situations are this straightforward. Sometimes an orthodontist needs to influence jaw growth in addition to teeth movement. For this purpose, they often use orthodontic headgear, which runs around the back of the head or neck and attaches to orthodontic brackets on the teeth. It still involves an anchor but in this case it's the patient's own skull.
In some situations, an orthodontist may feel he or she needs more anchorage as the teeth alone may not be enough. For this, they might establish a separate or additional anchor point using a temporary anchorage device (TAD). A TAD resembles a tiny screw that's inserted into the jawbone near the tooth intended for movement. The orthodontist can then attach the TAD to braces hardware using some form of elastics. After treatment, they remove the TAD.
These are just a couple examples of specialized tools an orthodontist can use for bite correction. Thanks to them and similar devices, even the most complex bite problem can be overcome to create a healthier and more attractive smile.
