What is a Root Canal?
Los Angeles Root Canal Therapy: What Is It and Why Do I Need It?
Your dentist may have suggested to you that Root Canal Therapy ( otherwise known as Endodontics ) was needed for a particular tooth. They may have briefly discussed some of the facts concerning the procedures involved in root canal therapy but perhaps you would like some more information.
Years ago, a badly infected tooth, or one that just had significant decay, was doomed to be extracted. Today the majority of these teeth can be salvaged through a procedures utilized by both the General Dentist and the specialist, the Endodontist.
Extraction is truly our last resort!
Some indications of the need for root canal treatment may be:
- Spontaneous pain or throbbing while biting.
- Sensitivity to hot and cold foods.
- Severe decay or an injury that creates an abscess (infection) in the bone.
Root Canal treatment consists of:
- The removal of the infected or irritated nerve tissue (Fig.2) that lies within the root of the tooth. It is this infected pulp tissue that causes an eventual abscess.
- The first step in a Los Angeles root canal is to obtain access to the nerve. This is accomplished by establishing a small access opening in the top of the tooth. It will be done under a local anesthetic. ( Fig. 3 )
- The length of the root canals is determined and the infected pulp is removed.
- At the same visit, the canal where the nerve is located will be reshaped and prepared to accept a special root canal filling material. This filling procedure will probably not occur until your next visit. The number of visits necessary to complete your root canal will depend upon several factors including the number of nerves in the tooth, the infected state of the nerve and the complexity of the procedure. (Fig. 4)
- The final step in your Root Canal will be the sealing of the root canal with a sterile, plastic material, called gutta percha This is done in order to prevent possible future infection.( Fig. 5)
- The tooth will then possibly need a post and core and a crown in order to re-establish normal form and function. This decision will be based upon several additional factors. (Fig. 6)
If treated early, root canals need not be uncomfortable. With the use of local anesthetics, the entire procedure can be totally painless.
Another “ Old Wive’s Tale “ is that by removing the nerve the tooth becomes “ dead “. This is not true. The tooth is very much alive and functioning because it receives a source of blood supply and nerve supply from the surrounding tissues that hold it in place in your jaw bone. The tooth will have no sense of feeling to hot, cold or sweets but will be responsive to biting pressures etc. With the proper restoration the tooth should last as long as your other teeth and can even be used as an anchor tooth for a partial denture or cemented bridge. The success rates for root canal therapy have been reported to be as high as 95%.
Sometimes when there has been long standing infection or abscess, there may be some soreness associated with the first or second root canal visit. If this should turn out to be true you will be given specific instructions to follow to minimize the discomfort. When an infection is present, it may be necessary to take an antibiotic. If pain should be present, analgesics may need to be prescribed. In either case, be sure to call your dental office if either of these problems should arise.
POSTOPERATIVE INSTRUCTIONS
- Postoperative discomfort is sometimes experienced after a treatment visit. This is due to irritation of the bone surrounding the tooth and may range from a mild discomfort in the area to an occasional episode of considerable pain. This discomfort will usually maximize in approximately 48-72 hours and then subside. Please avoid chewing on the treated tooth for a few days.
- If a throbbing sensation occurs please keep your head elevated as much as possible and place extra pillows under your head when lying down. Avoid as much as possible any strenuous activity as well.
- If your tooth has been left open to aid in drainage of an infection, please place cotton in your tooth as directed. Do not leave the cotton in the tooth between meals.
- If swelling of the gum is present or should appear after a treatment visit, please rinse the area every 1-2 hours with a solution of warm salt water prepared by adding a teaspoon of salt to an 8 oz. Glass of warm water.
- If swelling of the face is present or should appear, apply an ice pack to the area for 5 minutes every ½ hour.
- If antibiotic medication has been prescribed please take it as indicated until you have finished ALL of the medication. If you encounter any difficulty in breathing or a skin rash, or gastric disturbance should occur, please discontinue the medication and call the office.
- If medication for pain has been prescribed , please take it as indicated. It is important to bear in mind that narcotic medications such as Codeine, Vicodin, Percodan and Demerol may make you drowsy. Therefore, caution should be exercised in operating any potentially dangerous machinery or an automobile.

Amy Agzarian9/15/2026If you need a caring and quality dentist, come to this place! I've been with them for 15 years and referred many of my co-workers and friends. They treat you like family. They do not recommend aggressive procedures and try to preserve existing teeth. They are compassionate and keep you informed throughout the treatments about what is going on and inquiring about your comfort level. They give you a stress ball to hold and water and a towel at completion. They have a lovely cottage office and greet you by name as you arrive. They have all the necessary covid protocols in place. It is really a perfect dental experience. I'm very happy to write this review because they truly deserve it. I trust them completely.read moreread less

Daniel Blatt8/07/2026This is only a preliminary review. But I offer it because customer service means so much to me.I haven't seen a dentist in nine years and needed one as I have been experiencing some pain in two molars. When I found that my health insurance did not cover the dentists my friends recommended, I started toggling between the dentists on my plan and yelp.Dr. Kezian's son was the first to come up who was both on my plan and had good ratings. So, I called. The receptionist Melissa couldn't have been nicer and was able to schedule an appointment within forty-eight hours.When I went in to Dr. Kezian's office, the staff, Dr. Kezian himself, and his wife (also a dentist), couldn't have been more friendly. And they were helpful.The kindness made a difference. Now, we'll see what kind of difference a cleaning makes... and that is ten days hence.read moreread less

Lisa Meredith8/04/2026This is my third visit since switching dentists after my lifelong dentist closed his business during the pandemic. I have been impressed with the friendliness of staff, the tightly organized and coordinated team, the safety/cleanliness protocol, and the attention to details including the bottle of water and Motrin following a painful crown replacement.read moreread less
Caesar Jackson (COG)7/22/2026What can I say. The most MARVELOUS and EXCELLENT Dentistry business in my opinion.Before I found Dr. Kezian, I did not like to go to the dentist, AT ALL!

Now in my old age I see the benefit.Dr. Kezian and Associates are Amazing! Awesome service, awesome everything..To me, they are the dental professionals with the magic hands in Dentistry. I LOVE going to this Dentist ♥. Thank you DR. KEZIAN!read moreread less
Scott Archimbaud7/09/2026I had a dental emergency Friday at 330 of 4th of July weekend. My left front tooth fell out. I made an appointment with my regular dentist but it wasn't til Tuesday. I googled emergency dentist and made an appointment at a national chain that was open Saturday. Showed up and they didn't have my info. They couldn't help me today. I'm the parking lot I again googled and Dr Kezian came up. I called and he answered himself. He could take me right then on a Saturday morning at 9 am. Went over there and they could not have been nicer or more professional. They fixed me up in an hour and I was off. Their billing was fair too. It seems there may be a father Dr Kezian and a son Dr Kezian. I saw the son. He and his assistant were terrific. Highest praise!Update 4 yrs laterI am a huge fan of Dr. Steve Kezian, his office, and his entire staff. My teeth are legitimately a mess -- periodt -- and not once have I felt any judgment about my dental situation.That alone makes this practice worth its weight in gold.I first saw Dr. Kezian four years ago after a dental emergency hit over July 4th weekend. He took me last-minute on a Friday afternoon, fixed me right up, and I was on my way. Since then, I've mostly seen him and his team for last-minute emergency procedures, and every single time they've found a way to get me in quickly and conveniently. They consistently go the extra mile, their charges are reasonable, and the whole team makes what could be a stressful experience feel completely manageable.If you're looking for a dentist in Larchmont who treats you with genuine care and zero judgment, go see Dr. Steve or one of the other Kezians. Can't recommend themread moreread less

All the doctors Kezian are great.read moreread less
