Dr. Ahn is an expert, and I always feel that I can trust his skills. This office runs like a tight ship, no waiting in the reception area. The email and text appointment reminders are a friendly way to remind me to be on time....Read more

By Robert W. on March 7, 2015 6:00 PM
Approximately 4 years ago I hired these folks to extract 4 lower teeth and to replace with 4 implants.  They did a marvelous job.......very professional.  So.....Sept 4th of 2014 I went back for another extraction and for a future implant.  This particular upper molar was excruciating to remove.....I was in the chair for 1 1/2 hours.....they had to cut it up into pieces to extract....but I accepted the pain and went home with an antibiotic prescription....which is standard for all dental work.  After a few days I was experiencing horrible sinus headaches......I called them and went in.....they gave me another antibiotic prescription......the same one I just took for a week.  Soon after all those pills were used up.......my sinus condition was deteriorating rapidly.....with horrible drainage 24/7 into my throat.......basically  I was swallowing pus......down my throat day and night!  I called again......they prescribed another bout of antibiotics......my third round of pills..... a heavier duty one......another 10 days of pills.  After they were used up.......I was seeing no improvement and the left side of my sinuses were totally plugged up.......I could not breath through that side of my nose.  This sinus infection had gone on now for 3 months......and I was in huge pain......so I called back and they said......better find an Ear, Nose, and Throat doctor.  I located a great one here in Santa Cruz (Dr Hetzler)......and after some Prednisone (no help) I had to go in for a CTScan.......luckily I have medicare.....that scan was $1333!  Soon after my doctor scheduled a date for surgery.......the surgery was approximately 5 months after my tooth extraction.......he went and and had to scrap out all the pus and infection.......again some pain.  It's now a month  after the surgery......I can now breath easily......the infection is gone and back to normal......thanks to Dr Hetzler.   When I first checked in with the dentists with my issue.......they told me "they went by the book.....the usual protocol for extractions.......I know they did their best but I told them when I came in I did not have this horrible infection........and I walked out with one of the most excruciating head issues that a human can endure.......sleepless nights....and terrible drainage day and night.  And I truly thought they might call one day to see how I was doing along the healing path........not a single call!! I had to initiate every contact.  And about 3 weeks ago I email them with my news about surgery.......and I get no call back.......but i do get an email from one of their receptionists that their insurance company will be calling me!!  I receive no call from the insurance folks......so i call them about a week later........and now I have obtained all the doctors documents to file a claim........not what I had ever planned to do.......but I came home that day with a major infection that iIdid not cause......and now feel that there should be some kind of recourse.......I also talked to my regular dentist along the way and she said that there is not real cure for sinus infections.......that was not good news......but I'm now infection free and will not go back to the Central Dental Implant Group.  I also sent them thousands of dollars worth of business.......and really never received even a thanks for sending in more friends.  So......good luck with extractions and I hope no one ever has to experience a major sinus infection....Read more

I've been coming here for the last couple years since it's close by and the reviews were good. The office is very clean and nice, but does get cold in the early hours in winter. The waiting area is decently comfortable and the staff is very nice. All of them are korean so it's easy for that group to communicate....Read more

By Kath P. on February 26, 2014 6:00 PM
I first learned about Central Dental when I saw a coupon for a dental implant.  My husband had been putting it off because of the cost.  The coupon allowed him to replace his tooth so much more affordably, and the service and dental work really impressed him.  I just switched over to them myself recently.   I've had two fillings and a crown done, all within my budget for the first time, and not a single problem afterward with my teeth.  The staff is friendly, efficient, and there is not a lot of chit-chat, which I appreciate.  I am impressed by the way they have embraced technology - digital x rays, reminders for the appt. on my cell phone etc.  I'd recommend this dental group to anyone. Plenty of parking....Read more

During my last 4 months of extensive ongoing dental work I have always had the best treatment from all staff and doctors.

I've been searching for a new dentist I can trust with major restorative procedures.  Dr. Ahn at Central Dental Group is it.  I had a perfect extraction done with no problems afterwards.  He'll be doing my implant in a few months and I have complete confidence in him.  His staff are all really nice.  Lois at the front is very knowledgeable about insurance and scheduling questions.  His charges are reasonable considering that his office is modern and beautiful.  Congratulations to Dr. Ahn and his staff on their very successful dental practice!!  Keep up the good work!...Read more
