Step by Step Root Canal Procedure

Here's a step-by-step guide to an Endodontic (root canal) procedure. The length of treatment depends on the severity and complexity of the tooth. Give us a call if you have any questions.

1. The endodontist examines and x-rays the tooth, then administers local anesthetic. After the tooth is numb, the endodontist places a small protective sheet called a “dental dam” over the area to isolate the tooth and keep it clean and free of saliva during the procedure.

2. The endodontist makes an opening in the crown of the tooth. Very small instruments are used to clean the pulp, nerves, from the pulp chamber and root canals and to shape the space for filling.

3. In our office we add an extra step in which we use the Waterlase MD laser system in two different settings. The first setting is the cleaning stage; water is introduced into the canals, producing a mini "carwash" so any left over debris is suctioned out. The second setting is the disinfection/drying out stage; this setting dries the canals and disinfects them to a point of sterilization before we proceed to step 4.

4. After the space is cleaned and shaped, the endodontist 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 by your dentist before the tooth is restored.

5. After the final visit with your endodontist, you must return to your dentist to have a crown or other restoration placed on the tooth to protect and restore it to full function.

6. If the tooth lacks sufficient structure to hold the restoration in place, your dentist or endodontist may place a post inside the tooth. Ask your dentist or endodontist for more details about the specific restoration planned for your tooth.

Please note, steps 5 and 6 are typically performed by your general dentist

Face Shields: Do We Need Them?

The last few months have brought many changes on how the world operates. Dental offices are no exception. In our office, we wear extra gear, such as wearing mask at all times, disposable jackets, hair bouffant cap, gloves and etc. According to a recent article in the The Wall Street Journal: “With face shields a growing part of hospital protocol, some infectious disease doctors are calling for greater adoption outside the medical setting.” You may wonder, how does a face shield offer protection from COVID-19? Let’s understand how one gets infected with COVID-19. This virus spreads through droplets that are released into the air from an infectious person when they cough, sneeze or talk. The mouth, nose and the eyes are potential areas of how the virus can get into your system. Masks protect your mouth and nose, but what about the eyes? According to the vice president of the Infectious Diseases Society of America and an infectious disease physician Dr. Daniel McQu

CBCT Scan: Maxillary Resorption by Tooth #1

Despite years of training and practice, it has been difficult to correctly diagnose what can barely be seen on 2-D intra-oral images. The Kodak 3D extra oral imaging (CBCT) shows the whole picture from the axial, coronal, and sagittal views. CBCT provides additional information that is essential when used in Endodontics for finding evidence of resorption . This patient was diagnosed with pain in the maxillary right area. The patient was sent to this office for root canal therapy on tooth 2. Ordinary radiographs did not show a clear picture of the area. A CT was taken and the results show resorption of tooth #2 by tooth #1. Clearly the prognosis is poor. CT scans are recommended to diagnose the relationship of tooth #1 in relationship to tooth #2. If you're in any doubts as to the prognosis of your patient's tooth, please let us help you save a tooth.
