Why Choose Us
For over four decades, Saddleback Valley Endodontics has been the practice South Orange County turns to for specialist-level care that is ethical, precise, and genuinely patient-centered.
A long-standing record as a high-quality, ethical practice — trusted by the community and referring dentists throughout South Orange County since 1982.
Every doctor is a Diplomate of the American Board of Endodontics — a credential held by only about 20% of endodontists. It reflects a commitment to being the very best in the specialty.
We use GentleWave G4, CBCT 3D imaging on every case, Zeiss surgical microscopes, and AI — tools that improve outcomes, reduce discomfort, and leave nothing to guesswork.
From our board-certified specialists to our experienced clinical and front-office staff, every member of our team brings exceptional skill and genuine care to every appointment.
We are the practice dentists and their own families choose when they need endodontic treatment. That level of trust is the highest endorsement we know.
Dr. Jönsson completed a full implant dentistry fellowship at Loma Linda University — giving our team significantly more surgical training and experience than a typical endodontic practice.

Patient Reviews
Dr Jonsson is the best doctor in the world. I've been to a handful of doctors in my life and never have I met a doctor with such amazing bedside manners and care and patience towards his patients. I went in for an emergency root canal and was crying because I was so nervous. He treated me with such care from the moment he started until he ended. I felt no pain and not even the numbing shot.
Starting with the consultation, the staff were all very professional and patient. Dr. Jonsson spent the time to explain everything clearly and really made me feel like I was in good hands. My procedure was quick and painless. Dr. Jonsson made sure that comfort was a top priority and also explained every step of the process as we went. After the procedure, Dr. Jonsson followed up later that day to check on how I was feeling.
I've had this procedure before and it was the absolute worst experience. HOWEVER, this time was the complete opposite. Dr. Jonsson and his staff assured me they would make it a better experience. Well they didn't lie. It wasn't even close. It was literally the BEST dental experience of my life. I would highly recommend Dr. Jonsson and his team for any endodontic needs. Best of the best!!
I had a stressful root canal situation and consulted Dr. Jonsson for a second opinion. He put my mind at ease after analyzing my case, and the retreatment process went very smoothly and efficiently. Going here essentially saved my tooth and this will be my go-to for endodontic care going forward.
Dr. Jonsson took the time to explain every step of the procedure, answered all my questions, and ensured I was comfortable throughout the entire process. What impressed me most was their gentle touch and precise technique — I barely felt a thing! I had minimal discomfort afterward and I love that he followed up with me the same day to see how I was feeling.
I came to Saddleback Valley Endodontics with a very complex case involving inflammation and bone loss, and what I experienced was nothing short of miraculous. I never thought I would say this about a root canal, but I almost fell asleep in the chair. There was zero tension and absolutely zero pain. It wasn't general anesthesia — it was simply the result of Dr. Chu's incredible skill and the stress-free environment he creates.
I needed a root canal. I was treated by Dr. Wayland Chu and let me tell you He is TRULY AMAZING!!! I did not feel anything and could have fallen asleep there. The most pleasant experience ever in a Dentist/Endodontic office. If I need anything in the future, this is my go-to place! 10/10!!!
I was having an after hours emergency this weekend. I was called Monday morning with no appointment and advised to come right in. Dr. Jonsson immediately brought me back, managed my pain and then gave me the root canal, expanding what he was doing every step to make sure I was comfortable. I cannot express enough gratitude to the compassion and swiftness Dr. Jonsson provided me with no appointment first thing on a Monday morning.
Every step of my root canal went smoothly and comfortably. From the admin staff and professional set up of my appointment, to Dr. Jonsson and his very calming demeanor, thorough explanation, and truly gifted skills. Literally the only discomfort during the entire process was the tiny bit during numbing and then a bit of soreness a few hours later. Dr. Jonsson even followed up later that night to see how I was feeling.
Dr. Jonsson is THE BEST endodontist! He successfully resolved a problem with an old root canal that had been done a few years ago by a previous dentist. It had been giving me pain for over a year, and other dentists were unable to solve the problem. Thanks to Dr. Jonsson's expertise, I am finally pain-free.
I do biopsies for a living as a physician and I can tell you good from bad almost immediately. I noticed when Dr Jonsson stepped in the room he just looks capable. The procedure was explained very clearly and honestly I never felt anything. I can't imagine his procedure being any better than it was — no pain, I can eat fine. I give this guy a 10.
Dr. Jonsson's treatment was so much more thorough and comfortable — he walked me through all of my options, didn't put pressure on a decision, and having the actual procedure done was super easy, quick, painless and I felt totally confident that my treatment was done effectively, especially after seeing the post procedure X-rays.
By far the best dental experience I've had. He answered any questions I had, and explained any risks I may encounter. I have anxiety and he was able to provide different treatment options. Also have a bad gag reflex and was very patient working with me.
Dr. Jonsson was very thorough and explained all aspects. There were no surprises. He even apologized for a long appointment but I was thrilled to have it accomplished in 1 visit. He texted me that night and the next morning to follow up on my status. I felt very well cared for!
I am notoriously difficult to numb and have a tremendous level of anxiety related to even routine dental procedures. This particular tooth was one of the most difficult to numb and treat. I can say with some certainty that if I had to have this done, I'm very glad it was done here. Dr. Jonsson was exceptional in every way.
Hands down the best experience I've had with a root canal. Dr. Chu and his team were so professional, the procedure was faster than the other root canals that I've had from other offices, and I felt absolutely no pain during or after!
I needed a root canal and was in extreme pain. I was so well taken care of! I was able to get in in a timely manner, they even stayed late for me. Dr Jonsson explained everything to me thoroughly and made me feel at ease. I never imagined getting a root canal could be a good experience. I highly recommend Dr Jonsson and his staff.
My tooth with a 20-year-old root canal needed additional attention. Dr. Jonsson explained the benefits of a new root canal procedure using today's technologies and was able to do that immediately. The process was more comfortable than I expected and I appreciated the doctor's ongoing descriptions of what was being done and why.
I have had two root canals here. Everyone is really nice and Dr. Jonsson is just amazing. Pain free and so easy. I have dental fears and TMJ which can make dental work challenging. Both root canals went so well I was shocked. They deserve more than 5 stars!
Dr. Jonsson is outstanding! He thoroughly explained every step of the procedure and made me feel completely comfortable. He made sure I wasn't in pain, and he was perfect at giving the numbing shots (which are usually a painful experience for me). His assistant Emily was also great, and the front desk staff were very friendly and professional.
