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.

Sometimes you need only a single solution to improve your smile: teeth whitening to brighten stained teeth; porcelain veneers or crowns to mask dental flaws; or a life-like dental implant to replace a missing tooth. But not all dental situations are that simple and sometimes require a combination of treatments.
A case in point: restoring a missing tooth within a poor bite. The absent tooth itself may be the cause of the bite problem if it’s been missing for some time: The nearby teeth tend to move or “drift” into the empty space, leaving no room for implant placement.
When this happens, you’ll first need orthodontic treatment to correct the bite problem. Not only will this open the space for the implant, it also comes with its own benefits. It obviously improves your smile appearance—but straighter teeth are also easier to keep clean of bacterial plaque, which reduces your disease risk. You may also experience better digestion after your teeth are properly aligned and able to function as they should during eating.
The traditional way to improve a bite is through metal braces. But there are some downsides: For one, braces can make it difficult to keep teeth adequately clean, making wearers more susceptible to tooth decay and gum disease. Braces are also quite visible and can detract from a person’s appearance (even more so if a missing tooth is involved).
Unless your situation requires braces, you can choose clear aligners as an alternative. These clear, computer-generated plastic trays are worn in sequence to gradually move teeth to their desired positions. Unlike braces, you can remove aligners for eating, cleaning or rare special occasions. And, they’re barely noticeable to others.
If you also have a missing tooth, you can have a temporary prosthetic (“false”) tooth built into your aligner trays. In this way you can still enhance your smile while undergoing aligner treatment.
Once your bite has been corrected, we can then proceed with restoring your missing tooth permanently with a dental implant. Although orthodontics adds to the time and expense of restoration, its often necessary to achieve the best result. Your future smile will be the better for it.
When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.
“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”
The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”
A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.
It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.
So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!

Henry Ford famously said a customer could have any color they wanted on their Model T “as long as it was black.” Those days are over—today’s cars and trucks come with a slew of options, and not just their paint color.
There’s something else with a wide array of possible options: your choice of toothbrush. Your local store’s dental care aisle has dozens of toothbrushes in a myriad of sizes, shapes and features. And many promise better hygiene outcomes because of their unique design.
It’s enough to make your head spin. But you can narrow your search for the right toothbrush— just look for these basic qualities.
Bristle texture. At this all-important juncture between brush and teeth, softer-textured bristles are better. That might sound counter-intuitive, but soft bristles are just as capable at removing bacterial plaque, that sticky tooth film most responsible for dental disease, as stiffer bristles. Stiffer bristles, on the other hand, can damage gums and cause recession. Also, look too for rounded bristles (gentler on the gums), and multi-leveled or angled ones for better access around teeth.
Size and shape. Toothbrushes come in different sizes because, well, so do mouths. Look, then, for a brush and bristle head that can comfortably reach all the teeth in your mouth. If you have problems with manual dexterity, choose a brush with larger grip handles. A brush that’s comfortable to use and easy to handle can make your brushing more effective.
ADA Seal of Acceptance. The American Dental Association tests hygiene products like toothbrushes. If they pass the association’s standards, the manufacturer includes the ADA Seal of Approval on their packaging. Not all submit their brushes for this evaluation, so the seal’s absence doesn’t necessarily mean a brush is of low quality. The seal, though, does tell you the product passes muster with dental professionals.
It often takes a little trial and error to find the right brush, but since you should change yours out every six months, it’s a small price to experiment. And, no matter how great the brush, it’s only as good at removing plaque as the hand that holds it. So, be sure you learn proper brushing techniques—that and the right brush will keep your teeth and gums healthy.

Osteoporosis is a major health condition affecting millions of people, mostly women over 50. The disease weakens bone strength to the point that a minor fall or even coughing can result in broken bones. And, in an effort to treat it, some patients might find themselves at higher risk of complications during invasive dental procedures.
Over the years a number of drugs have been used to slow the disease’s progression and help the bone resist fracturing. Two of the most common kinds are bisphosphonates (Fosamax) and RANKL inhibitors (Prolia). They work by eliminating certain bone cells called osteoclasts, which normally break down and eliminate older bone cells to make way for newer cells created by osteoblasts.
By reducing the osteoclast cells, older bone cells live longer, which can reduce the weakening of the bone short-term. But these older cells, which normally wouldn’t survive as long, tend to become brittle and fragile after a few years of taking these drugs.
This may even cause the bone itself to begin dying, a relatively rare condition called osteonecrosis. Besides the femur in the leg, the bone most susceptible to osteonecrosis is the jawbone. This could create complications during oral procedures like jaw surgery or tooth extractions.
For this reason, doctors recommend reevaluating the need for these types of medications after 3-5 years. Dentists further recommend, in conjunction with the physician treating osteoporosis, that a patient take a “drug holiday” from either of these two medications for several months before and after any planned oral surgery or invasive dental procedure.
If you have osteoporosis, you may also want to consider alternatives to bisphosphonates and RANKL inhibitors. New drugs like raloxifene (which may also decrease the risk of breast cancer) and teriparatide work differently than the two more common drugs and may avoid their side effects. Taking supplements of Vitamin D and calcium may also improve bone health. If your physician still recommends bisphosphonates, you might discuss newer versions of the drugs that pose less risk of osteonecrosis.
Managing osteoporosis is often a balancing act between alleviating symptoms of the disease and protecting other aspects of your health. Finding that balance may help you avoid future problems, especially to your dental health.
