Root canals often get a bum rap. Although the procedure saves millions of teeth every year, it's often erroneously portrayed as an unpleasant experience. And if that wasn't enough, a long-discredited medical theory has found new life on the internet asserting root canals are a health danger.
First off, root canals play an immensely important role in treating teeth with advanced decay. If not promptly treated, a cavity can turn into a major infection of the interior tooth pulp and root canals, and ultimately the supporting bone. Teeth with this level of decay are not long for this world.
A root canal treatment stops this disease process in its tracks. After numbing the tooth and surrounding gums, we drill a small hole into the tooth's interior and then remove all of the infected tissue within the pulp and root canals. After disinfecting these areas, we fill them with a rubber-like substance called gutta percha.
After sealing off the access hole—and later capping the tooth with a life-like crown—the tooth is secure from further decay. And, by the way, the procedure doesn't hurt, thanks to local anesthesia. If anything, any pain caused by the decay attacking the tooth's nerves has now been alleviated.
So, what about the idea floating on the Web that root canals are dangerous? The "root" for this conjecture is a theory by Weston Price, an early 20th Century dentist, that leaving a "dead" body part in the body leads to various health problems (including cancer). That would include a root-canaled tooth, which has had the living tissue in the pulp removed.
There's just one problem—Weston's theory was fully investigated in the 1950s and overwhelmingly discredited. The supposed cancer threat was also reviewed in a 2013 study, which found no link between root canals and increased cancer risk. In fact, dental patients who had undergone several root canals had a diminished risk.
Like all other health procedures, root canals have some risks of complication. But those complications are far from life-threatening—it's tooth-saving benefits are often worth the risk. So, fear not if your dentist says you need a root canal. It won't hurt and it won't endanger your health—and it could save your tooth.

You could have an unattractive smile because of a chipped tooth or one slightly out of alignment. Or, it could be both of the above, plus some heavy staining to boot. Correcting each flaw individually might require a combination of different methods like orthodontics or porcelain crowns, which can take an extended period of time to complete.
But you may be able to correct numerous smile flaws with just one method—and in no more than a couple of treatment visits. It's called direct veneers.
Unlike regular veneers, direct veneers don't require a dental technician to craft a thin porcelain shell to bond over teeth. Rather, a dentist applies a tooth-colored material called composite resin to the problem teeth and "sculpts" an entirely new look that can correct multiple dental flaws at one time.
The dentist usually begins the process by creating a model ("wax-up") of proposed changes based on physical impressions of the jaw and teeth. Both dentist and patient can study the model and modify it if necessary, when finalizing the treatment plan.
At a subsequent appointment, the dentist prepares the tooth surface for bonding by removing a thin layer of tooth enamel, then shapes the teeth to better accommodate the composite resin. This tooth prep is similar to that done with traditional veneers, so it's permanent—the teeth will require some form of restoration from then on.
After applying an etchant and a bonding agent, the dentist applies the composite resin in small amounts, hardening each layer with a special light before applying the next one. With each subsequent layer, the dentist sculps the composite material to eventually resemble the wax-up model.
After completing the composite application, the dentist then uses hand tools and a dental drill to complete shaping, as well as an abrasive strip between teeth to aid future flossing. After just a few hours, the transformation is complete.
Direct veneers are durable, but not to the same extent as regular veneers or other cosmetic enhancements. They can also pick up stains over time, and may require re-treatment at some point. Still, direct veneers are a cost-effective way to improve the appearance of teeth with multiple flaws that could radically change your smile for the better.
Nina Parker, the host of Love & Hip Hop for six seasons, is now busy with the new game show Blockbusters and her own talk show The Nina Parker Show. But even with a full plate, she took time recently for some personal care—getting a new smile.
Parker's fans are familiar with her noticeable tooth gap. But a video on TikTok in February changed all that: In the video, she teasingly pulls away a mask she's wearing to reveal her smile—without the gap.
Parker and other celebrities like Madonna, Michael Strahan and David Letterman are not alone. Teeth gaps are a common smile feature, dating back millennia (even in fiction: Chaucer described the Wife of Bath as being "gap-toothed" in The Canterbury Tales).
So, what causes a tooth gap? Actually, a lot of possibilities. The muscle between the teeth (the frenum) may be overly large and pushing the teeth apart. There may be too much room on the jaw, so the teeth spread apart as they develop. It might also have resulted from tongue thrusting or late thumb sucking as a child, influencing the front teeth to develop forward and outward.
A tooth gap can be embarrassing because they're often front and center for all the world to see, but they can also cause oral health problems like complicating oral hygiene and increasing your risk for tooth decay. They can also contribute to misalignment of other teeth.
Fortunately, there are ways to alleviate a gap. One way is to move the teeth closer together with either braces or removable clear aligners. This may be the best approach if the gap is wide and it's contributing to misalignment of other teeth. You may also need surgery to alter the frenum.
You can also reduce less-pronounced gaps cosmetically with dental bonding or porcelain veneers. Bonding involves applying a type of resin material to the teeth on either side of the gap. After some sculpting to make it appear life-like, we harden the material with a curing light. The result is a durable, tooth-like appearance that closes the gap.
A veneer is a thin wafer of porcelain, custom-made to fit an individual patient's tooth. Bonded to the front of teeth, veneers mask various dental flaws like chips, deformed teeth, heavy staining and, yes, mild to moderate tooth gaps. They do require removing a small amount of enamel on the teeth they cover, but the results can be stunning—completely transformed teeth without the gap.
Getting rid of a tooth gap can be a wise move, both for your smile and your health. You may or may not take to social media to show it off like Nina Parker, but you can feel confident to show the world your new, perfect smile.

X-rays are so interwoven into dental care that we often don't think twice about them. Even so, we shouldn't take this invisible form of radiation lightly—regular exposure at high levels can affect the human body, especially in children.
The ability of x-rays to pass through tissue greatly improves our ability to diagnose tooth decay and other dental diseases. But x-rays can also potentially harm those same tissues. Because children are more sensitive to x-ray energy, they run a greater risk for cellular damage that could lead to cancer later in life.
In reality, though, these potential risks from x-rays are extremely low—so low, in fact, dental professionals regard their use as altogether safe for children. Here's why.
The ALARA principle. Dentists and other healthcare providers perform x-ray diagnostics based on a principle known as ALARA (“As low as reasonably achievable”). This means dentists only utilize x-rays to gain the most diagnostic benefit at the lowest amounts of radiation exposure. As such, ALARA guides both the development of x-ray equipment and the protocols involved in using them.
Equipment advances. Today's x-ray devices are safer and more efficient, restricting x-ray emissions to a single beam without scattering radiation into the environment. A child's radiation exposure is further lowered with the use of digital x-rays, which produce images in less time than conventional film. Because of these and other advances, children are exposed to less radiation during x-rays than what they typically receive in a day from the outside environment.
Safe practices. Following the ALARA principle, dentists are quite conservative in their use of x-rays in children. The most common means of x-ray is the bitewing, which captures images primarily of the back teeth that are more prone to decay. Bitewings, which require a lower x-ray dosage than a full mouth x-ray, are usually spaced at least six months apart or longer depending on a child's risk for dental disease.
The efficiency of modern radiographic equipment coupled with their judicious use has drastically reduced the amount of x-ray radiation to which a child may be exposed, thus lowering their risk of future health issues. The benefit for saving a child's teeth from disease is well worth their use.

Dentists remove millions of teeth each year, often because of tooth decay or gum disease. But disease isn't the only reason—a tooth extraction might make it easier to straighten a crooked smile.
Realigning teeth for therapeutic or cosmetic reasons is a regular undertaking in dentistry, but the process itself often differs from person to person. Each individual patient requires their own treatment plan taking into account factors like the kind of bite problem involved, the size of the jaw and the space available to move teeth.
This plan could indeed involve removing teeth. For example, an abnormally small jaw could cause crowding. Not only can crowding move teeth out of position, it may also leave little to no room for moving teeth. Although dentists can minimize crowding by influencing jaw development in early childhood, removing teeth for more space is usually the only option available to older adolescents and adults.
Similarly, teeth can fail to erupt properly and remain partially or fully submerged beneath the gums (known as impaction). There is an orthodontic method for pulling an impacted tooth fully onto the jaw, but only if the tooth isn't too far out of alignment. Otherwise, it may be better to remove the impacted tooth and then correct any gaps with braces or a dental implant.
There's also a situation on the opposite side of the spectrum that could benefit from teeth removal—when one or more permanent teeth fail to form, known as congenitally missing teeth. This can cause gaps in the smile or a “lopsided” appearance where a tooth on one side of the jaw is present while its counterpart on the opposite side of the jaw is missing.
The missing tooth can be replaced by an implant, bridge or other restoration. But another option may be to remove the existing counterpart tooth, and then close the gaps. This can result in a much more attractive smile that might be simpler and less costly than replacing the missing tooth.
Again, the decision to remove teeth to improve smile appearance depends on the patient and their particular dental condition. But in the right situation, it could make straightening a smile easier and more effective.
