Ask any kid and they'll tell you just how valuable "baby" teeth really are—out of the mouth, of course, and under their pillow awaiting a transaction with the Tooth Fairy. But there's more to them than their value on the Fairy Exchange Market—they play a critical role in future dental health.
Primary teeth provide the same kind of dental function as their future replacements. Children weaned from nursing can now eat solid food. They provide contact points for the tongue as a child learns to speak. And they play a role socially, as children with a "toothsome" smile begin to look more like what they will become when they're fully mature.
But primary teeth also serve as guides for the permanent teeth that will follow. As a future tooth develops below the gum line, the primary tooth preserves the space in which it will erupt. Otherwise, the space can be taken over by other teeth. This crowds out the intended tooth, which may erupt out of position or remain impacted below the gum line.
In either case, the situation could create a poor bite (malocclusion) that can be quite costly to correct. But if we can preserve a primary tooth on the verge of premature loss, we may be able to reduce the impact of a developing malocclusion or even prevent it.
We can help primary teeth last for their intended lifespan by preventing tooth decay with daily oral hygiene or clinically-applied sealants and topical fluoride. If they do become infected, it may be worth the effort to preserve them using procedures similar to a root canal treatment.
If a tooth can't be preserved, then we can try to reserve the empty space for the future tooth. One way is a space maintainer, which is a stiff wire loop attached to metal band bonded around an adjacent tooth. This keeps other teeth from drifting into the space until the permanent tooth is ready to erupt, at which time we can remove the appliance.
Your child may be anxious to get another tooth to put under their pillow. But helping that primary tooth go the distance will be more than worth it for their future dental health.

Every year U.S. dentists perform around 25 million root canal treatments and save countless teeth from the ravages of decay. But if you search "root canal" on the Internet, you might encounter an unsettling charge against this tooth-saving treatment—that it causes cancer.
Root canal treatments are routinely used when tooth decay has infected the pulp, the innermost layer of a tooth. During the procedure, we access the pulp and remove all the infected tissue. We then fill the empty pulp and root canals, seal the access hole and later crown the tooth to prevent further infection. Without this intervention, the decay can continue to advance toward the roots and supporting bone, putting the tooth in imminent danger of loss.
So, is there any credibility to this claim that root canal treatments cause cancer? In a word, no: there's no evidence of any connection between root canal treatments and cancer—or any other disease for that matter. On the contrary: root canals stop disease.
As with other types of urban legends and internet hype, the root canal-cancer connection may have arisen from another discredited idea from the early 20th Century. A dentist named Weston Price promoted the notion that leaving a "dead" organ in the body led to health problems. From his perspective, a root canaled tooth with its removed pulp tissue fit this criterion.
In the mid-1950s, dentistry thoroughly examined Dr. Weston's theory pertaining to treatments like root canals. The Journal of the American Dental Association devoted an entire issue to it and found after rigorous scientific inquiry that the theory had no validity in this regard. Another study in 2013 confirmed those findings. In fact, the later study instead found that patients who underwent a root canal treatment had a 45 percent reduction in oral cancer risk.
Given the freewheeling nature of the Internet, it's best to speak with a dental professional about your oral health before trusting a post or article you've found online. Not only are they more informed than an unverified online source, they would certainly not knowingly subject you to a procedure to save a tooth at the expense of your health.

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.
