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, Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough 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 Kingston, ON 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.

According to the Centers for Disease Control and Prevention, half of adults age 30 and over suffer from some form of gum disease. Caused by plaque buildup, gum disease is an infection of the tissue that surrounds and supports the teeth. In its advanced stages, it is known as periodontal disease. If left untreated, it can result in the loss of tissue and bone that support the teeth, causing teeth loss. It’s a preventable condition seen far too often by Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough.

Research between periodontal disease and other diseases is ongoing. Some studies have indicated that gum disease is linked to other health conditions such as stroke or diabetes. Furthermore, while most factors that lead to periodontal disease are dependent on the individual (genetics, diet, poor oral hygiene) there is a possibility that periodontitis is capable of spreading from one person to another.

What the Research Says

Periodontitis is a gum infection, and the bacteria that cause the gums to become infected travels in saliva. Researches have used DNA coding techniques to track the path of infection from one person to another. In other words, kissing and close contact play a role in the transmission of the infection, so if you’re married to a spouse with periodontal disease, then your chances of having gum problems are slightly increased. Other studies have indicated that saliva contact is common in family settings through coughing, sneezing, and shared utensils and food. Children with parents who have periodontal disease are at a somewhat higher risk of developing it. At the same time, just because you exchange bacteria with your loved ones doesn’t mean you will get periodontal disease.

It is important to note that the scientific evidence supporting the spread of periodontal disease is limited and ongoing. The best way to prevent gum disease is through proper plaque control, which includes brushing, flossing, mouthwash, and twice a year trips for professional cleanings. Contact our Kingston, ON office if you have any questions about periodontal disease.

Regular dental cleanings and checkups at our Kingston, ON office are an excellent way to ensure everything is A-OK in your mouth. There’s a reason the Canadian Dental Association recommends a professional cleaning every six months!

Here’s what you can usually expect during your visit with Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough:

• Head and neck examination: The dentist or dental hygienist will look for anything out of the ordinary. He or she will check your lymph nodes and lower jaw joints (also known as TMJs).
• Dental examination: The dentist or hygienist will check for any signs of gum disease, tooth decay, loose or broken teeth, or damaged fillings. We’ll also check your bite, the contact between your upper and lower teeth, and the condition of any dental appliances you’re wearing. Sometimes we’ll also take a set of X-rays.
• Dental cleaning: Plaque and tartar will be removed and the dentist or hygienist will polish your teeth. Your teeth and gums will be flossed, and we’ll also make recommendations about proper brushing and flossing technique if we think you need them.

When you visit our Kingston, ON office regularly, we’ll be able to compare the status of your teeth and gums from one appointment to another. That ensures we will be able to tell where you’re doing great in taking care of your teeth, and if needed, where you’re doing not so well.

If you’re in need of serious help, we might recommend more frequent visits. But remember, the most important factor in your oral health is how you take care of your teeth and gums at home between appointments.

We strive to help our patients achieve and maintain radiant, healthy smiles! If you'd like to know more about exams and cleanings at our Kingston, ON office, or what you need to do at home to maintain an effective oral health routine, please let us know.
