Root Canal - Endodontics
To understand a root canal procedure, it helps to know about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue, and helps to grow the root of your tooth during development. In a fully developed tooth, the tooth can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.
Why would I need an endodontic procedure?
Endodontic treatment is necessary when the pulp, the soft tissue inside the root canal, becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, or a crack or chip in the tooth. In addition, an injury to a tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess.
Endodontic treatment treats the inside of the tooth. Endodontic treatment is necessary when the pulp becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, faulty crowns, or a crack or chip in the tooth. In addition, trauma to a tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess.
What are the signs of needing endodontic treatment?
Signs to look for include pain, prolonged sensitivity to heat or cold, tenderness to touch and chewing, discoloration of the tooth, and swelling, drainage and tenderness in the lymph nodes as well as nearby bone and gum tissues. Sometimes, however, there are no symptoms.
How does endodontic treatment save the tooth?
During root canal treatment, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed with a rubber-like material called gutta-percha. Afterwards, the tooth is restored with a crown or filling for protection. After restoration, the tooth continues to function like any other tooth.
Modern root canal treatment is very similar to having a routine filling and usually can be completed in one or two appointments, depending on the condition of your tooth and your personal circumstances. You can expect a comfortable experience during your appointment. Saving the natural tooth with root canal treatment has many advantages.
- Efficient chewing
- Normal biting force and sensation
- Natural appearance
- Protects other teeth from excessive wear or strain
Will I feel pain during or after the procedure?
Many endodontic procedures are performed to relieve the pain of toothaches caused by pulp inflammation or infection. With modern techniques and anaesthetics, most patients report that they are comfortable during the procedure.
For the first few days after treatment, your tooth may feel sensitive or sore especially if there was pain or infection before the procedure. This discomfort can be relieved with over-the-counter or prescription medications.
Your tooth may continue to feel slightly different from your other teeth for some time after your endodontic treatment is completed.
Endodontic treatment helps you maintain your natural smile, continue eating the foods you love and limits the need for ongoing dental work. With proper care, most teeth that have had root canal treatment can last as long as other natural teeth and often for a lifetime.
