A root canal is a common treatment used to remove bacteria and treat infections inside your tooth. Within each of your teeth is soft tissue known as the pulp. The pulp of your tooth contains nerves, blood vessels, and connective tissue.
When the pulp becomes infected, it causes a number of symptoms like inflammation, temperature sensitivity, and severe pain. A root canal is the process of removing the infected pulp tissue and sealing the tooth to prevent reinfection. All services in this
Tooth pulp can become infected from severe tooth decay, as well as injuries and fractures that allow bacteria to reach the inner parts of your tooth. A root canal allows you to save your natural tooth and preserve the function and appearance of your smile.
A dentist with endodontic training can perform specialized treatments to save the tooth and prevent extraction. These are the most common causes of inner tooth damage:
Fractures and chips - When a tooth breaks, the nerves and pulp may be exposed. This causes debilitating pain and discomfort that only root canal therapy can resolve.
Bacterial infections - After a tooth experiences decay or injury, oral bacteria quickly invade the interior structure of the tooth to cause severe inflammation and infection. This requires root canal therapy to remove infected tissues and save the tooth.
Injuries - Endodontists use special techniques to stabilize teeth after they’ve been shifted or dislodged from their sockets.
To perform your root canal treatment, your doctor begins by making a tiny opening in the crown of your tooth. They then use small specialized instruments to remove the infected pulp and clean the space within your tooth. Once the tooth is thoroughly cleaned, your doctor uses a rubber-like material to fill the inside of your tooth and seal the access opening.
Root canals are typically performed under local anesthesia, which reduces any pain or discomfort you may feel during the procedure. For most patients, modern root canal treatment is well tolerated and can be compared to getting a filling. After your root canal, you may experience some sensitivity. Over-the-counter pain medications are a good option for relieving discomfort as you recover.
After the root canal procedure, you and your dentist discuss restoring the treated tooth. In most cases, teeth that have undergone root canal treatment are topped with a dental crown. Dental crowns help preserve the structure of your tooth and can also improve its appearance.
With the appropriate care, your teeth that have had endodontic treatment can last as long as your other natural teeth. However, a tooth that has received treatment may fail to heal or pain may continue to exist. Improper healing can be caused by a number of things, including curved, narrow, or complicated accessory canals that were not addressed during the initial treatment, or by a crown or restoration not placed within an appropriate time period following the procedure. In some cases, new problems such as new decay or cracked or loose fillings can require re-treatment in a previously treated tooth.Sometimes, the pain may occur months or years after treatment. If so, Endodontic Retreatment may be needed.
Generally, a root canal is sufficient treatment to save teeth with injured pulp. Occasionally, though, a non-surgical procedure will not be sufficient to resolve the infection and your endodontist will recommend surgery. Endodontic surgery may also be necessary to locate fractures or hidden canals that do not appear on x-rays but still manifest painfully in the tooth. Damaged root surfaces or surrounding bone structure may also be treated with this procedure. The most common surgery used to save damaged teeth is an apicoectomy or root-end resection.
An apicoectomy is a simple procedure where an incision is made in the gum tissue to expose the bone and surrounding inflamed tissue. The damaged tissue is removed along with the end of the tooth root. A small filling is placed at the end of the root to seal it and prevent reinfection of the root, and the gum is sutured. The bone naturally heals and fills in around the root over a period of months restoring full function.
Cracked teeth have many types of symptoms, including pain when chewing, temperature sensitivity, or even pain with the release of biting pressure. It is also very common for pain to come and go, making the diagnosis of the cause of pain difficult to find. It is possible that cracks in an otherwise healthy tooth can lead to infection of the pulp tissue, which can spread to the bone and gum surrounding the problematic tooth.
Injuries to the mouth can cause teeth to be pushed backward into their sockets. Your endodontist or general dentist may need to reposition and stabilize your tooth. If the pulp remains healthy, then no other treatment is necessary. If the pulp becomes damaged or infected, root canal treatment is usually started within a few weeks of the injury and a medication, such as calcium hydroxide, will be placed inside the tooth. Eventually, a permanent root canal filling will be placed.
If an injury causes a tooth to be completely knocked out of your mouth, it is important that you act quickly and are seen by your dentist immediately! Should this happen to you, keep the tooth moist, and if possible, put it back into the socket. You can even put the tooth in milk or a glass of water (add a pinch of salt.) The length of time the tooth was out of your mouth and the way the tooth was stored, may influence the type of treatment you receive.
Very pleased with this first visit. I was seen promptly and professionally. The dentist was thorough in the exam. Glad I made the switch! P.S. The office space is the nicest I’ve ever seen…. and I used to work in a dental office!
