Every year U.S. dentists perform around 25 million root canal treatments and save countless teeth from the ravages of decay. But if you search "root canal" on the Internet, you might encounter an unsettling charge against this tooth-saving treatment—that it causes cancer.
Root canal treatments are routinely used when tooth decay has infected the pulp, the innermost layer of a tooth. During the procedure, we access the pulp and remove all the infected tissue. We then fill the empty pulp and root canals, seal the access hole and later crown the tooth to prevent further infection. Without this intervention, the decay can continue to advance toward the roots and supporting bone, putting the tooth in imminent danger of loss.
So, is there any credibility to this claim that root canal treatments cause cancer? In a word, no: there's no evidence of any connection between root canal treatments and cancer—or any other disease for that matter. On the contrary: root canals stop disease.
As with other types of urban legends and internet hype, the root canal-cancer connection may have arisen from another discredited idea from the early 20th Century. A dentist named Weston Price promoted the notion that leaving a "dead" organ in the body led to health problems. From his perspective, a root canaled tooth with its removed pulp tissue fit this criterion.
In the mid-1950s, dentistry thoroughly examined Dr. Weston's theory pertaining to treatments like root canals. The Journal of the American Dental Association devoted an entire issue to it and found after rigorous scientific inquiry that the theory had no validity in this regard. Another study in 2013 confirmed those findings. In fact, the later study instead found that patients who underwent a root canal treatment had a 45 percent reduction in oral cancer risk.
Given the freewheeling nature of the Internet, it's best to speak with a dental professional about your oral health before trusting a post or article you've found online. Not only are they more informed than an unverified online source, they would certainly not knowingly subject you to a procedure to save a tooth at the expense of your health.

Tooth loss is a problem that affects many seniors—and since May is Older Americans Month, this is a good time to talk about it. Did you know that more than a quarter of adults over age 75 have lost all of their natural teeth? This not only affects their quality of life but poses a significant health risk.
According to a study in The Journal of Prosthodontics, significant tooth loss is associated with increased risk for malnutrition—and also for obesity. If this seems like a contradiction, consider that when you have few or no teeth, it’s much easier to eat soft, starchy foods of little nutritional value than it is to eat nutritious fresh fruits and vegetables. If all of your teeth are missing, it’s especially critical to replace them as soon as possible.
There are several ways to replace a full set of missing teeth, including removable dentures, overdentures, and fixed dentures:
Removable dentures are the classic replacement teeth that you put in during the day and take out at night. (However, if you suffer from sleep apnea, research has found that keeping dentures in at night may help keep the airway open, so if you have this condition, be sure to mention it to your doctor and dentist it). Dentures have come a long way in terms of how convincing they look, but they still have some disadvantages: For one thing, they take some getting used to—particularly while eating. Also, wearing removable dentures can slowly wear away the bone that they rest on. As that bone gradually shrinks over time, the dentures cease to fit well and require periodic adjustment (re-lining) or a remake.
Overdentures are removable dentures that attach onto a few strategically placed dental implants, which are small titanium posts placed in the bone beneath your gums. Strong and secure, implants prevent the denture from slipping when you wear it. Implants also slow the rate of bone loss mentioned above, which should allow the denture to fit better over a longer period of time. The ability to maintain hygiene is easier because you can remove them for cleaning.
Fixed implant-supported dentures are designed to stay in your mouth all the time, and are the closest thing to having your natural teeth back. An entire row of fixed (non-removable) replacement teeth can usually be held in place by 4-6 dental implants. Dental implant surgery is an in-office procedure performed with the type of anesthesia that’s right for you. After implants have been placed and have integrated with your jaw bone—generally after a few months—you can enjoy all of your favorite foods again without worry or embarrassment.

Although teething is a natural part of your baby's dental development, it can be quite uncomfortable for them—and upsetting to you. During teething, children can experience symptoms like pain, drooling or irritability.
Teething is the two or three-year process of intermittent episodes of the primary ("baby") teeth moving through the gums. These episodes are like storms that build up and then subside after a few days. Your aim as a parent is to help your baby get through the "stormiest" times with as little discomfort as possible. To that end you may have considered using over-the-counter products that temporarily numb irritated gums.
Some of those numbing products, however, contain a pain reliever called benzocaine. In recent years, this and similar ingredients have been found to increase the level of a protein called methemoglobin in the bloodstream. Too much methemoglobin can result in less oxygen delivered to body tissues, a condition known as methemoglobinemia.
This oxygen decrease can cause shortness of breath, fatigue or dizziness. In its severest form it could lead to seizures, coma or even death. Children and infants are at high risk for benzocaine-induced methemoglobinemia, which is why the U.S. Food and Drug Administration has banned marketing for benzocaine products as pain relievers for teething infants and children.
Fortunately, there are alternatives for helping your child weather teething episodes. A clean, chilled (not frozen) teething ring or pacifier, or a cold, wet washcloth can help numb gum pain. You can also massage their gums with a clean finger to help counteract the pressure exerted by an emerging tooth. Be sure, though, that you're not allowing anything in your child's mouth like lead-based paint that could be toxic. And under no circumstances should you use substances containing alcohol.
For severe pain, consult your physician about using a pain reliever like acetaminophen or ibuprofen, and the proper dosage for your child. With these tips you can help your child safely pass through a teething episode.
Multi-platinum recording artist Janet Jackson has long been known for her dazzling smile. And yet, Jackson admitted to InStyle Magazine that her trademark smile was once a major source of insecurity. The entertainer said, “To me, I looked like the Joker!” It was only after age 30 that the pop icon came to accept her unique look.
Jackson is not alone. A study commissioned by the American Association of Orthodontists found that more than one third of U.S. adults are dissatisfied with their smile. But there’s good news—modern dentistry can correct many flaws that can keep you from loving your smile, whether you’re unhappy with the color, size, or shape of your teeth. Here are some popular treatments:
Professional teeth whitening: Sometimes a professional teeth whitening will give you the boost you need. In-office whitening can dramatically brighten your smile in just one visit.
Tooth-colored fillings: If you have silver-colored fillings on teeth that show when you smile, consider replacing them with unnoticeable tooth-colored fillings.
Dental bonding: If you have chipped, cracked, or misshapen teeth, cosmetic bonding may be the fix you’re looking for. In this procedure, tooth colored material is applied to the tooth’s surface, sculpted into the desired shape, hardened with a special light, and polished for a smooth finish.
Porcelain veneers: Dental veneers provide a natural-looking, long-lasting solution to many dental problems. These very thin shells fit over your teeth, essentially replacing your tooth enamel to give you the smile you desire.
Replacement teeth: Is a missing tooth affecting your self-confidence? There are several options for replacing missing teeth, from a removable partial denture to a traditional fixed bridge to a state-of-the-art implant-supported replacement tooth. Removable partial dentures are an inexpensive way to replace one or more missing teeth, but they are less stable than non-removable options. Dental bridges, as the name implies, span the gap where a tooth is missing by attaching an artificial tooth to the teeth on either side of the space. In this procedure, the teeth on both sides of the gap must be filed down in order to support the bridgework. Dental implants, considered the gold standard in tooth replacement technology, anchor long-lasting, lifelike replacements that function like natural teeth.
After coming to embrace her smile, Jackson asserted, “Beautiful comes in all shapes, sizes, and colors." If you don’t feel that your smile expresses the beauty you have inside, call our office to schedule a consultation. It’s possible to love your smile. We can help.

Dental veneers are a great way to transform a smile without the expense or effort often required of other restorations. These thin layers of dental material adhere to the front of teeth as a "mask" to cover chips, heavy staining or other blemishes.
Still, veneers require attention to detail for a successful outcome. Here's a step-by-step look at changing your dental appearance with veneers.
Step 1: Considering your options. While most veneers are made of dental porcelain, composite resin materials are increasingly popular. Although more prone to chipping or staining, composite veneers don't require a dental lab for fabrication. Another option, depending on your dental situation, are ultra-thin veneers that require little to no tooth preparation. Your dentist will help you decide which options are best for you.
Step 2: "Test driving" your new smile. We can help you "see" your future smile with special software that creates a computer image of your teeth with the planned veneers. We can also use composite material to fabricate a "trial smile" to temporarily place on your teeth that can give you the feel as well as the look of your future smile.
Step 3: Preparing your teeth. Unless you're getting no-prep veneers, we'll need to modify your teeth before attaching veneers. Although only 0.3 to 0.7 millimeters thick, veneers can still appear bulky on unprepared teeth. They'll look more natural if we first remove a small amount of enamel. A word of caution, though: although slight, this enamel removal permanently alters your teeth that will require them to have some form of restoration from then on.
Step 4: Attaching your new veneers. After the planning phase (which includes color matching to blend the veneers with the rest of your teeth), a dental lab creates your veneers if you've opted for porcelain. After they're delivered, we'll clean and etch the teeth with a mild acidic gel to increase the bonding effect. We'll then permanently attach the veneers to your teeth with a very thin but ultra-strong resin luting cement that creates a unified bond between the veneers and teeth.
Following these steps is the surest way to achieve a successful outcome. With due care you're sure to enjoy the effects for a long time to come.
