Hearing that you need a root canal can be highly intimidating. What is a root canal? It is the removal of the nerve supply from the tooth. Here, Dr. Gregory Weaver will describe the parts of a tooth and explain the reasons for a root canal and how it is done when you visit us in our Raleigh, NC office.

Your tooth is made up of many layers. The outside layer is called enamel and is made of minerals. The middle layer is dentin, which is also a calcified tissue, but less dense. The center of the tooth is called the pulp, and that hosts the nerves and blood vessels. A root canal is the removal and replacement of this center with a sterile filling.

A root canal is needed when an infection spreads to the center of the tooth. This can be from trauma (recent or previous), a cavity, a severe crack, or other compromise that causes nerve damage. An X-ray and examination are required to see if a root canal is needed. Symptoms may include but are not limited to pain, swelling, change in tooth color, and over-reaction to temperature change or pressure.

When it is time to begin, you’ll receive local anesthesia (via injection) to make you most comfortable. A rubber dam is used to isolate the tooth, while other equipment determines the nerve location and maintains a sterile working environment. All of the infected area is removed including the nerve tissue and blood vessels. Then, medicines are used to sterilize and alleviate any pain. Next is the placement of a filling material in the spot where the nerve used to be.

When your nerve and blood supply are taken away, the tooth is non-vital, or dead, and can become weak and fragile. If your tooth is badly decayed, a large portion of it will have to be removed. It is recommended to place a crown on the tooth to keep the enamel from breaking or falling apart. If you do not get a crown, you could eventually lose the tooth to more decay or infection. The tooth could also break off completely and you would have to have an extraction. The crown fits over the top of the tooth and secures it from breaking down.

A root canal saves the life of a tooth that would otherwise succumb to further infection and eventually extraction. Infection is the cause of most-needed root canals. If you are ever unsure what is happening at your appointment, don’t be afraid to ask questions so you understand the procedure completely.

The Importance of Facial Protection

Americans from all walks of life should mark April as National Facial Protection Month on their calendars. The American Association of Pediatric Dentistry, Academy for Sports Dentistry, American Academy of Pediatric Dentistry, and American Association of Oral and Maxillofacial Surgeons have combined forces to sponsor this annual campaign, which aims to educate and remind us of the importance of protecting our face and teeth against impacts and injuries.

Wearing a helmet can save your life and prevent devastating physical damage in a variety of situations, from playing football to riding a bicycle. According to the American Association of Oral and Maxillofacial Surgeons, helmets reduce the risk of various head injuries by as much as 85 percent. Whether helmet laws apply in your area or not, Dr. Gregory Weaver and our team at Weaver Dentistry want you to make sure you and your loved ones wear helmets with the appropriate safety ratings for specific activities. (A sticker on or inside the helmet will usually indicate this rating.) Helmets can also help save your teeth if they come with an attached faceguard, an essential addition for football players and others involved in contact sports.

Preventing Dental Injuries

A mouthguard can protect you against a variety of dental injuries, such as cracked, broken, or knocked-out teeth. The American Dental Association states that mouthguards play an essential role in preventing up to 200,000 dental injuries each year, and many states mandate their use for sports activities such as football and hockey. The Academy for Sports Dentistry warns, however, that these mouthguards must be custom-fitted as precisely as possible to prove effective. Have a professional-quality mouthguard molded and fitted by our team at Weaver Dentistry for better protection than a generic store-bought or “boil-and-bite” variety can offer. These cheaper versions tend to wear out quickly, interfere with proper breathing, and provide uneven degrees of cushion against impacts. Always have a fresh mouthguard fitted for each new sports season.

Choose the right combination of helmet, faceguard, and mouthguard to protect your teeth and face this April, and tell your friends to do the same! To learn more about mouthguards, or to schedule an appointment with Dr. Gregory Weaver, please give us a call at our convenient Raleigh, NC office!

At Weaver Dentistry, we know the human mouth contains a lot of bacteria. A bacterium can travel through your body with routine activities that are a normal part of daily living. You spread bacteria when you brush or floss your teeth, when you chew, and when you swallow.

For most people, bacteria don’t cause any problem. For some people, however, especially those who have chronic medical conditions, specific cardiac conditions, or whose immune systems are compromised, bacteria that spreads throughout the bloodstream can lead to much more serious bacterial infections.

The goal of pre-medication or antibiotic prophylaxis, Dr. Gregory Weaver will tell you, is to prevent bacterial endocarditis, a serious infection of the endothelial heart surfaces or the heart valves. The condition is also called infective endocarditis. A small population of people with certain health problems has a high risk for contracting this potentially deadly bacterium.

The American Heart Association states that people at greatest risk for contracting bacterial or infective endocarditis are:

• Patients who underwent cardiac valve surgery in the past
• Those who have suffered past incidents of infective endocarditis
• Patients who have mitral valve prolapse, resulting in or causing valve leakage
• People who have had rheumatic fever or any degenerative cardiac condition that produces abnormalities in cardiac valves
• Patients who suffer from certain congenital heart diseases

For these patients, any dental procedure may cause bleeding, and prophylactic antibiotic administration is recommended as a preventive measure.

Other patients who require prophylactic antibiotics

The American Association of Endodontists extends recommendations to patients who have undergone joint replacement surgery within the past two years, suffer from type 1 diabetes, or have immune deficiencies from diseases such as lupus, rheumatoid arthritis, or HIV; cancer patients whose immune systems are suppressed because of radiation or chemotherapy; people who have had organ transplants; and hemophiliacs.

The American Academy of Pediatric Dentistry also includes people who suffer from sickle cell anemia, as well as patients who suffer from conditions that require chronic steroid therapy.

Typical endodontic procedures for which antibiotic prophylaxis is recommended include root canal therapy (when it involves going deeper than the root apex), surgical tooth extractions, and any other dental, endodontic, or periodontal procedure during which the doctor anticipates bleeding.

Although different medical societies and organizations offer these guidelines as a way of identifying patients for whom prophylactic pre-medication is essential prior to dental procedures, dentists will take each patient's medical history and personal risk factors into consideration. Some doctors may choose to administer antibiotics following a procedure, especially for patients who have previously suffered from oral infections either as a result of dental procedures or that necessitated oral surgery.

Did you know there are as many types of dental fillings as there are flavors of ice cream? Okay, maybe that’s an exaggeration. Still, when you visit the dentist with a cavity, there are many filling options. Most of us just sit in the chair, open our mouths, and let the dentist work his or her magic. But have you ever stopped to consider what the dentist is filling and restoring your decayed or broken tooth with?

Five types of dental fillings

There are five basic kinds of dental filing material. The dentist decides which type to use based on the degree of the decay, the cost of the material, and the type of dental insurance you have.

1. Dental amalgam, or silver fillings, have been used to fill cavities for more than 150 years. Dental amalgam is the most common type of dental filling. It's strong, durable, and less expensive than other types.
2. Composite fillings, or white fillings, are popular because the color matches the rest of your teeth. Composite fillings are a combination of resin and plastic. They are more aesthetically pleasing than silver fillings, but are also less durable.
3. Ceramic fillings are durable and visually appealing (tooth-colored), but they are expensive. They are made of porcelain and have been shown to be resistant to staining.
4. Glass ionomers are typically used on children whose teeth are still changing. Constructed from glass and acrylic, glass ionomers are designed to last fewer than five years. The benefit of these dental fillings is that they release fluoride, which protects the changing tooth from further decay.
5. Unless you’re a rock or movie star, gold fillings aren’t common. While a gold filling is durable, non-corrosive, and can last more than 15 years, it not only takes more than one dental visit to place, but, as you can imagine, it is expensive.
