About Greenberg Dental & Orthodontics
Dr. Denise Six and the team frequently treat young children and families with several kids in braces or Invisalign at once, though scheduling and billing surprises come up often.
Greenberg Dental & Orthodontics is a general dental practice that also offers Invisalign and traditional braces, and many of its reviews involve young children or families getting several kids treated together. Dr. Denise Six is repeatedly credited with taking the time to pinpoint an exact diagnosis before starting treatment. Some reviewers describe gentle handling of anxious or first-time patients, including one who described a dental phobia and reported very little discomfort during the visit. Scheduling is a recurring sore spot, with long waits past appointment times and trouble reaching the office by phone showing up regularly, and a number of reviewers report cost surprises like quotes that changed after the visit.

Orthodontic care in reviews
A handful of orthodontic reviews describe the orthodontist as friendly and efficient, with monthly adjustments paired with regular cleanings and one family having several members treated with braces at the same location. A couple of reviewers mention issues, including a permanent retainer that came loose and needed re-bonding and one patient who was denied braces for age reasons on two separate occasions before eventually starting treatment.

Recent reviews from Google
It is an excellent place; I am very grateful to everyone for their care. Whenever I come with my children, we are made to feel welcome; they explain every step of the procedure in detail, and they speak both English and Spanish. The facility is clean and pleasant, and they use technology to ensure everything goes smoothly. I would undoubtedly recommend it 100%.
Dr. Cannon was unprofessional and very aggressive in his recommendations. I got a second opinion the next day from a dentist in Jax Beach and I was told that he is known for recommending unnecessary dental work. If you look at the other reviews, it’s true. You can’t get your tooth or your money back once he has done the work. And he doesn’t care, he just wants your money.
I came here because one side of my permanent retainer came loose, and I needed it re-bonded. They were only willing to replace the entire thing, and wanted to charge me $200 to remove the old one, and $700 to install a new one! It felt like they only wanted to upsell me, rather than do what was best for me. I instead went to a different orthodontist, and had it repaired for $60. This place was clearly trying to capitalize on the situation and over charge for a simple repair.
They never answer the phones, It is highly inconvenient and unprofessional that its impossible to get ahold of anyone at the front desk to make an appointment.
I have had such a great experience with Dr. Cannon at Greenberg Dental. The staff is very professional, the hygienists are great, and Dr. Cannon does a thorough job and explains everything so well. I wouldn’t go anywhere else.
