One word summary of this place: WOW! I have never been to a dentist office like this one. The facility is beautiful, the employees are super nice and the equipment is state of the art. Everyone from the front desk personnel to the dentist and everyone in between were super kind and helpful. The x-ray machines are super high tech, they can scan a 3D model of your teeth without having to put gross putty in your mouth for an impression and…… the seats have heat and massage settings.

Dr. Ata Dental Design have been taking care of my family as well as my extended family for over 20 years. They never disappoint. Dr. Joe and Dr. Jill have done a spectacular job of expanding the business from what Dr. Ata Sr. started. Always reinventing themselves, updating their location and providing the best staff and equipment. Paola, is hands down the best hygienist in the field. Kind, experienced and professional. Once you experience it you won't want to go to anybody else for all your oral health care.

Dental Crown in Forceps

Dental crowns are an effective solution for many common health and cosmetic tooth conditions. Now, thanks to state-of-the-art CEREC technology, we can restore a damaged tooth in a single office visit.

Dental Implants

Repair missing teeth and protect your oral health with dental implants. Implant-supported restorations are the gold standard in restorative dentistry, providing the same function and stability as natural teeth.

Some dental problems cannot wait until your next checkup. In the event of a dental emergency, you can contact our office for specialized care without delay.

Root Canal

When decay reaches the inner layer of a tooth, you are at risk for serious oral health complications. Root canal therapy eliminates tooth infection and can even prevent the need for extractions.

Do You Suffer From Dental Anxiety?

We believe all patients should feel comfortable at the dentist's office. If fear or nervousness is standing in between you and your treatment, consider sedation dentistry. Sedation can help patients with moderate to severe dental anxiety overcome the discomfort of treatment. Depending on your needs, we can offer nitrous oxide or oral conscious sedation options. If you are interested in learning more, please contact our offices in Orlando and Kissimmee. 

"I absolutely hate the dentist. However, I have to say Dr. Joe and his staff are amazing. They made me feel very comfortable. The procedure I had to have done was very surprisingly painless."
