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.

Dental amalgam—also known as “silver fillings”—has been used for nearly a hundred years to treat cavities. There are several reasons why this mixture of metals has been the go-to material among dentists: Malleable when first applied, dental amalgam sets up into a durable dental filling that can take years of biting forces. What’s more, it’s stable and compatible with living tissue.
But there’s been growing concern in recent years about the safety of dental amalgam, with even some wondering if they should have existing fillings replaced. The reason: liquid mercury.
Mercury makes up a good portion of dental amalgam’s base mixture, to which other metals like silver, tin or copper are added to it in powder form. This forms a putty that can be easily worked into a prepared cavity. And despite the heightened awareness of the metal’s toxicity to humans, it’s still used in dental amalgam.
The reason why is that there are various forms of mercury and not all are toxic. The form making headlines is known as methylmercury, a compound created when mercury from the environment fuses with organic molecules. The compound builds up in the living tissues of animals, particularly large ocean fish, which have accumulated high concentrations passed up through their food chain.
That’s not what’s used in dental amalgam. Dentists instead use a non-toxic, elemental form of mercury that when set up becomes locked within the amalgam and cannot leach out. Based on various studies, treating cavities with it poses no health risks to humans.
This also means there’s no medical reason for having an existing silver fillings removed. Doing so, though, could cause more harm than good because it could further weaken the remaining tooth structure.
The most viable reason for not getting a dental amalgam filling is cosmetic: The metallic appearance of amalgam could detract from your smile. There are newer, more life-like filling options available. Your dentist, though, may still recommend dental amalgam for its strength and compatibility, especially for back teeth. It’s entirely safe to accept this recommendation.
While not as prevalent as adults, teenagers can have missing teeth, usually from injury or from never having been formed. Fortunately, life-like dental implants can replace missing teeth. But unfortunately for teens, implants aren't usually a good option—yet.
That's because a teenager's jaws are still growing, and will continue until early adulthood. Dental implants don't adjust to this growth like natural teeth and will eventually look out of place. It's best, then, to consider a temporary restoration for a teenager. And, there are two excellent options: one removable and one fixed.
The first is a removable partial denture (RPD). Like a full denture, an RPD has an acrylic base that resembles gum tissue, to which prosthetic (false) teeth are attached to match the positions of the missing teeth. It's usually held in place with metal or nylon clips that slide under part of the natural teeth at the gum line.
RPDs are versatile and durable. But they're not designed to be worn indefinitely, so they can be damaged if subjected to excessive biting forces like biting into something hard. And, peer-pressured teens may also feel self-consciousness about wearing a “denture.”
The other option is a bonded bridge. It's similar to a traditional bridge, except how it's supported in the mouth. A traditional bridge gains its support from the crowns on each end attached to natural teeth, which must be permanently altered for them. By contrast, a bonded bridge has strips of dental material extending from both sides of its back that are bonded to the back of the adjacent natural teeth.
With the bonding material behind the bridge, it can't be seen—and the natural teeth won't require permanent alteration. But a bonded bridge is usually more costly than an RPD and less secure than a traditional bridge. And not every teen is a viable candidate for one: issues like how the teeth fit together and if the teen has a tooth grinding habit could be strikes against this fixed option.
Your dentist can help you sort out the best of these options for your teen. If cared for and maintained properly, either restoration can buy you time until your teen is ready for dental implants.

At the first-ever Players Weekend in August 2017, Major League Baseball players wore jerseys with their nicknames on the back. One player — Cleveland Indians shortstop, Francisco Lindor — picked the perfect moniker to express his cheerful, fun-loving nature: “Mr. Smile.” And Lindor gave fans plenty to smile about when he belted a 2-run homer into the stands while wearing his new jersey!
Lindor has explained that he believes smiling is an important part of connecting with fans and teammates alike: “I’ve never been a fan of the guy that makes a great play and then acts like he’s done it 10,000 times — smile, man! We’ve got to enjoy the game.”
We think Lindor is right: Smiling is a great way to generate good will. And it feels great too… as long as you have a smile that’s healthy, and that looks as good as you want it to. But what if you don’t? Here are some things we can do at the dental office to help you enjoy smiling again:
Routine Professional Cleanings & Exams. This is a great place to start on the road toward a healthy, beautiful smile. Even if you are conscientious about brushing and flossing at home, you won’t be able to remove all of the disease-causing dental plaque that can hide beneath the gum line, especially if it has hardened into tartar, but we can do it easily in the office. Then, after a thorough dental exam, we can identify any problems that may be affecting your ability to smile freely, such as tooth decay, gum disease, or cosmetic dental issues.
Cosmetic Dental Treatments. If your oral health is good but your smile is not as bright as you’d like it to be, we can discuss a number of cosmetic dental treatments that can help. These range from conservative procedures such as professional teeth whitening and bonding to more dramatic procedures like porcelain veneers or crowns.
Tooth Replacement. Many people hide their smiles because they are embarrassed by a gap from a missing tooth. That’s a shame, because there are several excellent tooth-replacement options in a variety of price ranges. These include partial and full dentures, bridgework, and dental implants. So don’t let a missing tooth stop you from being Mr. (or Ms.) Smile!

Braces are a common experience among teens and pre-teens. And although the treatment can be a major financial undertaking, more and more families pursue it to help their child attain a straighter, more attractive smile.
But orthodontics isn’t first and foremost a cosmetic treatment. Although an improved appearance is a benefit, the main reason for treatment is therapeutic—it can improve your child’s current and future dental health.
The teeth’s relationship to the jaws and gums makes moving them possible. Rather than simply being fixed within their jawbone socket, teeth are actually held in place by a strong, elastic tissue called the periodontal ligament. The ligament lies between the teeth and jawbone and attaches to both with tiny extending fibers. This attachment secures the teeth in place.
But the ligament also has a dynamic quality—it can reshape itself when necessary and allow teeth to move gradually into new positions. This is most necessary during the early years of mouth and jaw development, but it can also occur throughout life. Orthodontics takes advantage of this mechanism by applying precise pressure to the teeth in the direction of desired movement. The periodontal ligament does the rest by reshaping and allowing the teeth to move in response to this pressure.
The result is straighter teeth and a more normal bite. With the teeth now where they should be, it’s also easier to clean them of disease-causing dental plaque, whereas misaligned teeth are more prone to plaque accumulation that can be difficult to remove. And because the whole mouth including teeth are involved when we talk, teeth positioned in a more normal bite will improve speech.
Orthodontics is a long-term process, often encompassing more than the actual time wearing braces. Both orthodontists and pediatric dentists recommend a bite evaluation by an orthodontist around the age of 6. If it does appear an abnormal bite is forming, it may be possible to intervene and stop or at least slow the development. This could have a more positive impact on any future treatment.
Braces and other treatments can make a difference in your child’s self-image and social relationships. But the main beneficiary will be their dental health.
