About Sierra Dental & Orthodontics - Tennyson

Adults come here often, and reviews note a low-pressure approach where dentists give an opinion but don't push treatments like Invisalign or Botox.

Sierra Dental & Orthodontics - Tennyson is a general dental practice that also offers Invisalign for patients interested in straightening their teeth. Reviews often mention a notably adult patient base and describe the office as one that avoids upselling, with several people noting they were never pushed toward procedures like fillings or Botox they hadn't wanted. Cost and insurance come up often too, with many reviewers calling pricing reasonable and appreciating help navigating coverage, though a smaller number describe billing errors or unexpected balances. Dr. Jacob Son, who reviewers say is taking over from Dr. Williams, is frequently mentioned for explaining treatment thoroughly and remembering details between visits.

Been coming for 5ish years, I encourage people to come here. Always so helpful with insurance and never once felt I was pressured into extra expenses or services that weren’t necessary.

. Overall I am pleased with Sierra Dental & Orthodontics! I had surgery today due to bone loss in lower jaw. Dr Kim and her assistant were very caring and patient. While I am currently in pain I was given great advice along with pain medication, oral mouth rinse, etc. Tomorrow and every day after I know I will feel better. Thank You for putting my mind at ease.:)

Embarrassingly, I had not been to the dentist in several years, so I was quite nervous going into my appointment. However, the entire staff was incredibly friendly, understanding, and informative. They very quickly eased my anxieties and addressed all of my concerns without ever shaming me for not having a professional cleaning for the past 4ish years. I’m very happy to have found a dentist that I feel comfortable returning to for the foreseeable future.

I recently had to switch dentist practices and found sierra dental, they’re wonderful! The process to book an appointment was super easy, the hygienist was kind and did a great job on my cleaning, and the Dr. Williams was so nice and professional and talked through all my questions and dental history with me! If you’re looking for a new dentist or just want to change to a wonderful practice, I highly recommend sierra dental!
