This patient was hit in the mouth, fracturing his front tooth. I was able to save the tooth with a root canal, composite buildup, and porcelain crown. Here are the before and after pictures.
This patient is a 19 year old young man who suffered a seizure and passed out and smashed his face on a concrete sidewalk. He fractured his upper central incisors exposing the nerves. I was able to save the teeth with root canals, buildups, and porcelain crowns. These are the before and after pictures.
What is a root canal?
To understand root canal treatment, it helps to know something 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 creates the surrounding hard tissues of the tooth during development.
The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root. The pulp is important during a tooth’s growth and development. However, once a tooth is fully mature it can survive without the pulp, because the tooth continues to be nourished by the tissues surrounding it
A root canal 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, 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.
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.
The dentist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the root canal, then fills and seals the space. Afterwards, a crown or other restoration on the tooth to protect and restore it to full function. After restoration, the tooth continues to function like any other tooth.
Many root canal procedures are performed to relieve the pain of toothaches caused by pulp inflammation or infection. With modern techniques and anesthetics, most patients report that they are comfortable during the procedure.
For the first few days after treatment, your tooth may feel sensitive, 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 root canal treatment is completed.
Root canal treatment can often be performed in one or two visits and involves the following steps:
1. The dentist examines and x-rays the tooth, then administers local anesthetic. After the tooth is numb, a small protective sheet called a “dental dam” is placed over the area to isolate the tooth and keep it clean and free of saliva during the procedure.
2. An opening in the crown of the tooth. Very small instruments are used to clean the pulp from the pulp chamber and root canals and to shape the space for filling.
3. After the space is cleaned and shaped, the dentist fills the root canals with a biocompatible material, usually a rubber-like material called gutta-percha. The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening. The temporary filling will be removed usually 1 week later.
Can all teeth be saved with a root canal?
Most teeth can be saved. Occasionally, a tooth can’t be saved because the root canals are not accessible, the root is severely fractured, the tooth doesn’t have adequate bone support, or the tooth cannot be restored.
