It's not an exaggeration to say the modern root canal treatment has saved millions of teeth over the last century. Without this procedure, there's not a lot we can do to stop advanced tooth decay from infecting and destroying a tooth.

What's more, a root canal treatment could extend the life of a tooth for decades. Notice we said could—although most root canals do have satisfactory outcomes, there's still a chance a tooth may become re-infected. Here are 3 possible causes for an unsuccessful root canal treatment, and what you can do to lessen their impact.

The severity of the infection. Tooth decay usually begins at the enamel layer, softened by the acid produced by bacteria. Untreated, the infection can then spread through the next tooth layer of dentin until finally infecting the innermost pulp. From there the infection can move through the root canals to the bone, dramatically increasing the danger to the tooth. Root canal treatments have a higher chance of success the earlier they're performed in the disease progression, so see your dentist at the first sign of pain or other tooth abnormality.

The root canal network. An effective root canal procedure eliminates all dead or diseased tissue in both the pulp chamber and the root canals (these are then filled to prevent future infection). But this may prove difficult with teeth that have intricate root canal networks because of a higher risk of overlooking some of the canals. It may be best in such cases for an endodontist, a specialist in treating interior tooth issues, to perform the procedure using their advanced techniques and microscopic equipment.

The age of the tooth. Root canal treatment can weaken a tooth's structural integrity, especially with older teeth. This can make them more susceptible to fracture and a higher chance of infection. We can avoid this outcome by placing crowns on root-canaled teeth: The crown provides structural strength to the tooth and can add further protection against infection. Older teeth may also benefit from the placement of a small support post within it to further add stability before applying the crown.

Keeping your teeth and gums healthy isn't always easy—and it's even more of a challenge if you're wearing orthodontic appliances like braces. That's why a fair percentage of patients wearing braces also contend with tooth decay or periodontal (gum) disease.

The reason is simple: The orthodontic hardware makes it difficult to fully reach all parts of teeth surfaces with your toothbrush or floss. As a result, you can miss removing some of the accumulated plaque, the thin film of bacteria and food particles most responsible for dental disease. And it only takes a short amount of time (just days with gum disease) for a bacterial infection to begin.

But while avoiding dental disease is difficult while wearing braces, it's not impossible. Here are 4 ways you can minimize your dental disease risk while undergoing orthodontic treatment.

Be diligent with your daily hygiene. Even though it's more difficult, don't slack on daily brushing and flossing. It does require more time to work the brush around and between the wires and brackets, but taking the time will help you clear away more plaque you might otherwise miss. It may also help to switch to a multi-tufted, microfine bristled toothbrush if you're not already using one.

Use a water irrigator. If straight thread flossing is proving too difficult (and even with a floss threader), try using a water irrigator. This device emits a pulsating spray of pressurized water that loosens and flushes away plaque between teeth. Clinical studies consistently show water flossing is effective for reducing plaque in orthodontic patients.

Lower your sugar intake. Sugar left over in the mouth is a prime food source for bacteria that cause tooth decay or gum disease. Reducing sugary foods and snacks can help reduce bacterial populations and lower your disease risk. You can also fortify your oral health with healthier foods that contain calcium and other minerals.

Keep up regular dental visits. In addition to your orthodontic adjustments, don't neglect your regular visits with your family dentist. Semi-annual cleanings help remove any plaque and calculus (calcified plaque) you may have missed. Your dentist can also monitor your health and boost your disease prevention through topical fluoride treatments or prescribed antibacterial mouth rinses.

National Physical Fitness & Sports Month in May, sponsored by the President's Council on Sports, Fitness & Nutrition, is a fitting time to encourage us to play sports. Many of us already feel the Spring itch to get out there and get involved. Unfortunately, an increase in sports or exercise activities also means an increase in potential physical injury risks, including to the face and mouth.

Although COVID-19 protective measures are delaying group sports, there's hope that many leagues will be able to salvage at least part of their season. If so, you should know what to do to keep yourself or a family member safe from oral and dental injuries.

First and foremost, wear a sports mouthguard, a plastic device worn in the mouth to reduce hard impacts from other players or sports equipment. A custom-fitted guard made by a dentist offers the best level of protection and the most comfortable fit.

But even though wearing a mouthguard significantly lowers the chances of mouth injuries, they can still occur. It's a good idea, then, to know what to do in the event of an oral injury.

Soft tissues. If the lips, cheeks, gums or tongue are cut or bruised, first carefully clean the wound of dirt or debris (be sure to check debris for any tooth pieces). If the wound bleeds, place some clean cotton gauze against it until it stops. If the wound is deep, the person may need stitches and possible antibiotic treatments or a tetanus shot. When in doubt, visit the ER.

Jaws. A hard blow could move the lower jaw out of its socket, or even fracture either jaw. Either type of injury, often accompanied by pain, swelling or deformity, requires medical attention. Treating a dislocation is usually a relatively simple procedure performed by a doctor, but fractures often involve a more extensive, long-term treatment.

Teeth. If a tooth is injured, try to collect and clean off any tooth pieces you can find, and call us immediately. If a tooth is knocked out, pick it up by the crown end, clean it off, and place it back into the empty socket. Have the person gently but firmly clench down on it and call the office or go to the ER as quickly as possible. Prompt attention is also needed for teeth moved out of alignment by a hard blow.

Playing sports has obvious physical, mental and social benefits. Don't let an oral injury rob you or a family member of those benefits. Take precautions and know what to do during a dental emergency.

If there's anything that makes Alfonso Ribeiro happier than his long-running gig as host of America's Funniest Home Videos, it's the time he gets to spend with his family: his wife Angela, their two young sons, and Alfonso's teenaged daughter. As the proud dad told Dear Doctor–Dentistry & Oral Health magazine, "The best part of being a father is the smiles and the warmth you get from your children."

Because Alfonso and Angela want to make sure those little smiles stay healthy, they are careful to keep on top of their kids' oral health at home—and with regular checkups at the dental office. If you, too, want to help your children get on the road to good oral health, here are five tips:

• Start off Right—Even before teeth emerge, gently wipe baby's gums with a clean, moist washcloth. When the first teeth appear, brush them with a tiny dab of fluoride on a soft-bristled toothbrush. Schedule an age-one dental visit for a complete evaluation, and to help your child get accustomed to the dental office.
• Teach Them Well—When they're first learning how to take care of their teeth, most kids need a lot of help. Be patient as you demonstrate the proper way to brush and floss…over and over again. When they're ready, let them try it themselves—but keep an eye on their progress, and offer help when it's needed.
• Watch What They Eat & Drink—Consuming foods high in sugar or starch may give kids momentary satisfaction…but these substances also feed the harmful bacteria that cause tooth decay. The same goes for sodas, juices and acidic drinks—the major sources of sugar in many children's diets. If you allow sugary snacks, limit them to around mealtimes—that gives the mouth a chance to recover its natural balance.
• Keep Up the Good Work—That means brushing twice a day and flossing at least once a day, every single day. If motivation is an issue, encourage your kids by letting them pick out a special brush, toothpaste or floss. You can also give stickers, or use a chart to show progress and provide a reward after a certain period of time. And don't forget to give them a good example to follow!
• Get Regular Dental Checkups—This applies to both kids and adults, but it's especially important during the years when they are rapidly growing! Timely treatment with sealants, topical fluoride applications or fillings can often help keep a small problem from turning into a major headache.

Bringing your kids to the dental office early—and regularly—is the best way to set them up for a lifetime of good checkups…even if they're a little nervous at first. Speaking of his youngest child, Alfonso Ribeiro said "I think the first time he was really frightened, but then the dentist made him feel better—and so since then, going back, it's actually a nice experience." Our goal is to provide this experience for every patient.

If you have questions about your child's dental hygiene routine, call the office or schedule a consultation. You can learn more in the Dear Doctor magazine article “How to Help Your Child Develop the Best Habits for Oral Health.”

Dental visit anxiety is a serious problem: Half of all Americans admit to some level of dental fear, while 15% avoid dental care altogether due to acute anxiety. The harm this can cause to dental health is incalculable.

But dentists have a number of sedation techniques that can relax anxious patients and allow them to receive the care they need. Although often used together, sedation is slightly different from anesthesia, which aims to deaden pain sensation. The aim of sedation is to calm the emotions and state of mind.

Sedation isn't a new approach: Physicians have used substances like root herbs or alcohol to relieve anxiety since ancient times. Modern dentistry also has a long history with sedation, dating from the early 1800s with the first use of nitrous oxide gas.

Modern dental sedation has expanded into an array of drugs and techniques to match varying levels of anxiety intensity. At the milder end of the scale are oral sedatives, taken an hour or so before a dental appointment to produce a calmer state. This may be enough for some patients, or it can be used in conjunction with nitrous oxide.

For those with more intense anxiety, dentists can turn to intravenous (IV) sedation. In this case, the sedative is delivered directly into the bloodstream through a small needle or catheter inserted in a vein. This causes a quicker and deeper reaction than oral sedatives.

Although similar to general anesthesia, IV sedation does differ in significant ways. Rather than unconsciousness, IV sedation places a patient in a “semi-awake” state that may still allow them respond to verbal commands. And although the patient's vital signs (heart rate, breathing, blood pressure, etc.) must be monitored, the patient doesn't need breathing assistance as with anesthesia.

There's one other benefit: The drugs used often have an amnesic effect, meaning the patient won't remember the treatment experience after recovery. This can be helpful in creating more pleasant memories of their dental experience, which could have its own sedative effect in the future.

Whether oral, gas or IV, sedatives are a safe and effective way to calm dental fears during treatment. That could help someone with anxiety maintain their oral health.
