Dr. Gannon Lee DDS - Mission Viejo, California

Never did it ever cross my mind that one day I’d be dealing with TMJ, but here I am…tired of opening my mouth just to bite into a burger. On some days, my jaw pain is so bad that I simply don’t feel like eating. I’m the type of person that lets ailments and conditions “play out” but this one happened to linger and not improve over several months.

By sheer coincidence and blessing, I was introduced to Dr. Lee who was able to diagnose my symptoms and offer a treatment/solutions. From start to finish, his attention to detail was second to none. Check out the warm welcome from the front desk as I entered the lobby (see photo).

Based on the roadmap that was recommended by Dr. Lee, I’m confident that my road to recovery will allow me to once again bite into a juicy In N Out Double Double burger without fear of experiencing sharp pain.

If you’re experiencing jaw pain or sleep apnea (his other specialty), don’t be like me and hope that it’ll go away on its own. Do yourself a favor and go see a specialist. Allow Dr. Lee to do what he does best.

I went to Dr Gannon Lee’s office today for my first teeth cleaning appointment since selecting him as my dentist. I was scheduled with Elyse. I was impressed because right away she started by discussing my medical history and then ask if there was anything additional she should know. Which yes, there was. I’ve never had a hygienist ask me anything about my health. Just “do you have any teeth bothering you?”. Anyway, in addition to that she made the entire process as comfortable as possible. No one likes to have their teeth cleaned but she made it very easy. I highly recommend her and Dr Lee’s office.

Excited to get my new snoring device ( MAD) that Dr Lee made for me. My apnea is pretty bad and this device allows me to get air at night with out having to use a CPAP machine .

I have had 2 mouth devices made by Dr. Lee. Although he is a good doctor, the overall experience has not been good. Neither of the devices have worked well with my Sleep Apnea and Snoring. And every time I had to go back to have the device adjusted for a more comfortable fit, I was asked to pay $150.00 cash. The staff rudely emphasize on the fact that neither of my 2 insurance companies cover adjustments (for a device that they custom made for me themselves) and request $150.00 for a 5 minute appointment.

Dr. Gannon Lee and his team are the best! I was a challenging patient today with a new mouthpiece, and they went far and above to make sure I was comfortable. A 30 minute appointment went much longer, but they didn’t make me feel bad about it. I highly recommend this dental practice. Simply the best!

Dr Lee and his team were able to see me quickly for a toothache. The team was warm & friendly and put me at ease right away. Dr Lee was kind and exceptionally thorough. I am so grateful to be under their care!

Everyone there is so friendly and professional. They got me in as a new patient pretty quickly, and got me a new mouth splint for my TMJ issues within a few weeks. Highly recommend Dr. Gannon and his staff. He truly listens to your problems and concerns and takes the time to make sure everything is perfect.

I highly recommend Dr. Lee to anyone seeking specialized and compassionate TMJ care.
