DontFeartheRootCanal-ItCouldJustSaveYourTooth

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.

SedationCanHelpanAnxiousChildRelaxDuringDentalTreatment

There are different ways to ease a child's potential nervousness with dental visits, like starting those visits around their first birthday or seeing a pediatric dentist who specializes in children. But even doing those things won't guarantee your child won't develop some form of dental anxiety, which could complicate their dental care.

To help make appointments easier for anxious children, many dentists use conscious sedation as a means of helping them relax. With this technique, the dentist administers a mild sedative to the child to take the edge off their nervousness, while allowing them to remain awake during treatment.

Sedation isn't anesthesia, the means we use to stop pain during treatment (although sedation may be used with anesthesia). Rather, sedation reduces emotional fear and anxiety. And unlike general anesthesia, a sedated child can still breathe without assistance and, depending on the depth of the sedation, respond to physical and verbal stimuli.

In most cases, children are administered sedation medications by mouth, usually as a syrup, although on occasion it might be delivered intravenously with an IV. The dose is usually given some time before their treatment session after the dentist has evaluated them. Dentists mostly use mild sedatives like Midazolam or Hydroxyzine with very little risk of side effects for children.

During the procedure, a designated staff member continually monitors the child's vital signs. Besides heart rate, pulse and respirations, they may also check the child's exhaled carbon dioxide levels to ensure they're breathing normally.

After the treatment session is over, staff will continue to monitor the child until their vital signs return to pre-sedation levels. If the child is of driving age, they'll need someone to drive them home. Children who've been sedated should remain home for the rest of the day, but they can usually return to school the next day depending on what kind of dental work they've undergone.

Dentists follow strict protocols for pediatric sedation adopted by the American Academy of Pediatrics, the American Dental Society, and the American Academy of Pediatric Dentistry. In addition, many states have also established processes for administering sedation therapy. It's a safe and effective method to ease a child's anxiety over their dental visit.

ImplantsCouldHelpYouKeepRemainingTeethLonger

It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.

This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.

Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.

Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.

Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.

In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.

More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.

HeresWhyX-RaysareaSafePracticeWithChildren

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.

MikeTysonThePrizefighterPrizesHisUniqueSmile

Mike Tyson made a splash when he faced off against sharks during the Discovery Channel's Shark Week 2020. But there's bigger news for fans of the former undisputed world heavyweight champion: After a 15-year absence, he will enter the ring again for two exhibition matches in the Fall. However, it's not just Tyson's boxing action that made news during his 20-year career. His teeth have also gotten their fair share of press.

Tyson used to be known for two distinctive gold-capped teeth in the front left side of his mouth. He made headlines when he lost one of the shiny caps—not from a blow by a fellow pugilist but from being headbutted by his pet tiger as Tyson leaned in for a kiss. Tyson's teeth again garnered attention when he had his recognizable gold caps replaced with tooth-colored restorations. But the world champion may be best known, dentally at least, for his trademark tooth gap, or “diastema” in dentist-speak. Several years ago, he had the gap closed in a dental makeover, but he soon regretted the move. After all, the gap was a signature look for him, so he had it put back in.

That's one thing about cosmetic dentistry: With today's advanced technology and techniques, you can choose a dental makeover to suit your individual taste and personality.

An obvious example is teeth whitening. This common cosmetic treatment is not a one-size-fits-all option. You can choose whether you want eye-catching Hollywood white or a more natural shade.

If your teeth have chips or other small imperfections, bonding may be the solution for you. In dental bonding, tooth-colored material is placed on your tooth in layers and then hardened with a special light. The material is matched to your other teeth so the repaired tooth fits right in. This procedure can usually be done in just one office visit.

For moderate flaws or severe discoloration, porcelain veneers can dramatically improve your appearance. These thin, tooth-colored shells cover the front surface of the tooth—the side that shows when you smile. Veneers are custom-crafted for the ideal individualized look.

Dental crowns can restore single teeth or replace missing teeth as part of a dental bridge. Again, they are manufactured to your specifications. With restorations like crowns and veneers, the smallest detail can be replicated to fit in with your natural teeth—even down to the ridges on the tooth's surface.

And if, like Mike Tyson, you have a gap between your teeth that makes your smile unique, there's no reason to give that up if you opt for a smile makeover. Whether you would like a small cosmetic enhancement or are looking for a more dramatic transformation, we can work with you to devise a treatment plan that is right for you.
