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.

Your teeth face a hostile environment populated by disease-causing bacteria. But your teeth also have some “armor” against these microscopic foes: enamel. This hard outer tooth layer forms a barrier between harmful bacteria and the tooth’s more vulnerable layers of dentin and the inner pulp.
But although it’s tough stuff, enamel can erode when it comes into contact with high concentrations of mouth acid. Losing substantial amounts of enamel could leave your teeth exposed to disease.
So, here are 3 things you can do to help protect your enamel so it can keep on protecting you.
Careful on the brushing. Brushing removes dental plaque, a thin bacterial film on teeth most responsible for dental disease. But be careful not to brush too often, too hard and too quickly after eating. Brushing more than twice a day can cause gum recession and enamel wear; likewise, brushing too aggressively. You should also wait at least 30 minutes after eating to brush to give your saliva sufficient time to neutralize any acid. You could lose tiny bits of softened enamel brushing too soon.
Cut back on acidic foods and beverages. Spicy foods, sodas and, yes, sports and energy drinks all contain high amounts of acid that can increase your mouth’s acidity. It’s a good idea, then, to reduce acidic foods and beverages in your diet. Instead, eat less spicy foods and drink primarily water or milk. Also, look for foods and beverages with calcium, which helps increase your enamel’s ability to remineralize after acid contact.
Don’t eat right before bedtime. There are a lot of reasons not to eat just before you hit the hay—and one of them is for protecting your tooth enamel. Saliva normally neutralizes acid within a half hour to an hour after eating. While you’re sleeping, though, saliva production decreases significantly. This in turn slows its neutralizing effect, giving acid more contact time with enamel. So, end your eating a few hours before you turn in to avoid too much acid remaining on your teeth.
There are a number of teeth whitening options to put the brightness back into your smile — from professional dentist office applications to over-the-counter products for home use. But before you decide on an option, you should first consider whether whitening is right for you and to what extent.
Here are 3 questions to ask yourself — and us — before undergoing a whitening treatment.
Do I have any dental problems that make whitening problematic? The underlying cause of the staining may stem from decay, root canal problems or other dental issues; in these cases the underlying cause needs to be treated first, because whitening would only mask the actual problem. You also may not want to whiten your teeth for aesthetic reasons: people with certain features like short teeth or gummy smiles may find these features become more prominent after teeth whitening. It might be more advisable in these cases to consider other cosmetic options first.
How much whitening do I really need to improve my smile? One of the biggest myths about teeth whitening is the brighter the shade the more attractive the smile. A truly attractive tooth color, however, is more nuanced, and every person’s ideal color is different. The most attractive and natural color is one that matches the whites of your eyes.
What effect will whitening have on existing dental work I already have? In most cases, none — and that could be a problem. Composite resins or ceramic dental material have their color “baked in” and bleaching chemicals used in whitening have no effect on them. The concern then is whether whitening nearby natural teeth may produce a color mismatch between them and the dental restorations, resulting in an unattractive appearance.
Before you decide on teeth whitening, visit us first for a complete exam and consultation. We’ll discuss whether whitening is a good option for you, or whether there are other issues we should address first. We can also advise you on products and techniques, and how to get the most from your whitening experience.

If there's anything that makes Alfonso Ribeiro happier than his long-running gig as host of America's Funniest Home Videos, it's the time he gets to spend with his family: his wife Angela, their two young sons, and Alfonso's teenaged daughter. As the proud dad told Dear Doctor–Dentistry & Oral Health magazine, "The best part of being a father is the smiles and the warmth you get from your children."
Because Alfonso and Angela want to make sure those little smiles stay healthy, they are careful to keep on top of their kids' oral health at home—and with regular checkups at the dental office. If you, too, want to help your children get on the road to good oral health, here are five tips:
- Start off Right—Even before teeth emerge, gently wipe baby's gums with a clean, moist washcloth. When the first teeth appear, brush them with a tiny dab of fluoride on a soft-bristled toothbrush. Schedule an age-one dental visit for a complete evaluation, and to help your child get accustomed to the dental office.
- Teach Them Well—When they're first learning how to take care of their teeth, most kids need a lot of help. Be patient as you demonstrate the proper way to brush and floss…over and over again. When they're ready, let them try it themselves—but keep an eye on their progress, and offer help when it's needed.
- Watch What They Eat & Drink—Consuming foods high in sugar or starch may give kids momentary satisfaction…but these substances also feed the harmful bacteria that cause tooth decay. The same goes for sodas, juices and acidic drinks—the major sources of sugar in many children's diets. If you allow sugary snacks, limit them to around mealtimes—that gives the mouth a chance to recover its natural balance.
- Keep Up the Good Work—That means brushing twice a day and flossing at least once a day, every single day. If motivation is an issue, encourage your kids by letting them pick out a special brush, toothpaste or floss. You can also give stickers, or use a chart to show progress and provide a reward after a certain period of time. And don't forget to give them a good example to follow!
- Get Regular Dental Checkups—This applies to both kids and adults, but it's especially important during the years when they are rapidly growing! Timely treatment with sealants, topical fluoride applications or fillings can often help keep a small problem from turning into a major headache.
Bringing your kids to the dental office early—and regularly—is the best way to set them up for a lifetime of good checkups…even if they're a little nervous at first. Speaking of his youngest child, Alfonso Ribeiro said "I think the first time he was really frightened, but then the dentist made him feel better—and so since then, going back, it's actually a nice experience." Our goal is to provide this experience for every patient.
If you have questions about your child's dental hygiene routine, call the office or schedule a consultation. You can learn more in the Dear Doctor magazine article “How to Help Your Child Develop the Best Habits for Oral Health.”
Breathing: You hardly notice it unless you're consciously focused on it—or something's stopping it!
So, take a few seconds and pay attention to your breathing. Then ask yourself this question—are you breathing through your nose, or through your mouth? Unless we're exerting ourselves or have a nasal obstruction, we normally breathe through the nose. This is as nature intended it: The nasal passages act as a filter to remove allergens and other fine particles.
Some people, though, tend to breathe primarily through their mouths even when they're at rest or asleep. And for children, not only do they lose out on the filtering benefit of breathing through the nose, mouth breathing could affect their dental development.
People tend to breathe through their mouths if it's become uncomfortable to breathe through their noses, often because of swollen tonsils or adenoids pressing against the nasal cavity or chronic sinus congestion. Children born with a small band of tissue called a tongue or lip tie can also have difficulty closing the lips or keeping the tongue on the roof of the mouth, both of which encourage mouth breathing.
Chronic mouth breathing can also disrupt children's jaw development. The tongue normally rests against the roof of the mouth while breathing through the nose, which allows it to serve as a mold for the growing upper jaw and teeth to form around. Because the tongue can't be in this position during mouth breathing, it can disrupt normal jaw development and lead to a poor bite.
If you suspect your child chronically breathes through his or her mouth, your dentist may refer you to an ear, nose and throat (ENT) specialist to check for obstructions. In some cases, surgical procedures to remove the tonsils or adenoids may be necessary.
If there already appears to be problems brewing with the bite, your child may need orthodontic treatment. One example would be a palatal expander, a device that fits below the palate to put pressure on the upper jaw to grow outwardly if it appears to be developing too narrowly.
The main focus, though, is to treat or remove whatever may be causing this tendency to breathe through the mouth. Doing so will help improve a child's ongoing dental development.
