If you’ve ever read online that root canal therapy causes cancer, don’t be alarmed—it doesn’t. What it does do is save a deeply decayed tooth that might otherwise be lost.
Tooth decay is caused by acid produced by bacteria, which dissolves enamel to create a hole or cavity. But it doesn’t stop there: decay can move on to infect the tooth’s innermost layer, the pulp filled with nerves and blood vessels. Unchecked, the resulting infection can travel through the root canals to eventually infect the bone.
A root canal treatment stops the infection before it goes this far. After administering a local anesthetic, we drill a small hole into the tooth to access the pulp chamber and root canals. We then remove all the diseased tissue, disinfect the space and then place a filling within the empty chamber and root canals to prevent further infection. We then seal the access hole and later crown the tooth to further protect and stabilize it.
It’s no exaggeration, then, to say that root canal treatments have saved millions of teeth. So, for all its beneficial effect, why is it considered by some to pose a health danger?
The germ for this notion comes from the early 20th Century when a dentist named Weston Price theorized that leaving a “dead” organ in place would harm the body. Since a root-canaled tooth with the pulp’s living tissue removed is technically no longer viable, it fit the category of “dead” tissue. Thus, according to this theory, maladies like cancer could arise because of the “dead” tooth.
Unfortunately, this theory has found a somewhat new life recently on the internet, even though it was thoroughly investigated and debunked in the 1950s. And as late as 2013, a study published in a journal of the American Medical Association found no increased cancer risk after root canal treatment, and even some evidence for a reduced risk.
So, if your dentist recommends root canal treatment, rest assured it’s needed to save your tooth. Rather than harm your health, it will improve it.

When a woman learns she's pregnant, her first thought is often to do everything possible to protect the new life inside her. That may mean making lifestyle changes like avoiding alcohol or quitting smoking.
Some women may also become concerned that their regular dental visits could pose a risk to their baby. But both the American Congress of Obstetricians and Gynecologists and the American Dental Association say it's safe for pregnant women to undergo dental exams and cleanings—in fact, they're particularly important during pregnancy.
That's because pregnant women are more susceptible to dental infections, particularly periodontal (gum) disease, because of hormonal changes during pregnancy. The most common, occurring in about 40% of expectant mothers, is a form of gum disease known as pregnancy gingivitis. Women usually encounter this infection that leaves the gums tender, swollen and easy to bleed between the second and eighth month of pregnancy.
Untreated, pregnancy gingivitis could potentially advance below the gum line and infect the roots. It could also have an unhealthy effect on the baby: some studies show women with severe gum disease are more prone to give birth to premature or underweight babies than women with healthy gums.
But it can be stopped effectively, especially if it's treated early. Regular dental checkups and cleanings (at least every six months or more frequently if your dentist recommends) can help an expectant mother stay ahead of a developing gum infection.
With that said, though, your dentist's approach to your care may change somewhat during pregnancy. While there's little concern over essential procedures like gum disease treatment or root canal therapy, elective restorations that are cosmetic in nature might best be postponed until after the baby's birth.
So, if you've just found out you're pregnant, let your dentist know so they can adjust your care depending on your condition and history. And don't be concerned about keeping up your regular dental visits—it's a great thing to do for both you and your baby.

Just like adults, teenagers experience chipped, stained or disfigured teeth. And during a life stage where issues with appearance can be acutely painful, these defects call out for a solution.
And, there is one: porcelain veneers. These thin wafers of custom-made porcelain are bonded to the front of teeth to cover dental flaws. They’re one of the least invasive—and most affordable—methods for smile enhancement.
There is one caveat, though: The affected teeth will most likely need alteration. Veneers can look bulky when bonded directly to teeth, so we compensate for this by removing some of the surface enamel. This changes the tooth permanently, to the point that it will always require a veneer or some other form of restoration.
But although this may be a minor issue for an adult, it could pose a problem for a teenager. That’s because the pulp, the innermost layer of a tooth containing nerves and blood vessels, is larger in a younger adolescent tooth than in an older adult tooth. Because of its size, it’s closer to the tooth’s surface. During enamel reduction for veneers on a young tooth, this could lead to inadvertent nerve damage. If that happens, the tooth may need a root canal treatment to preserve it.
If the adolescent tooth needing a “facelift” has already been root canaled or sustained significant structural damage, then altering it for veneers may not be too concerning. Likewise, if the teeth are smaller than normal, the bulkiness of a veneer may actually improve appearance and not require alteration. We’ll need to examine a young patient first before making any recommendations.
There are also alternatives to veneers for improving smile appearance. Enamel staining could be enhanced temporarily with teeth whitening. Small chips can be repaired with bonded dental material, or in skilled hands be used to “build” a veneer one layer at a time with no enamel reduction. Although not as durable as regular veneers, these bonding techniques could buy time until the tooth is more mature for veneers.
Whichever path we take, there are effective ways to transform a teenager’s flawed tooth. And that can make for an even better smile.
