Services
General Dentistry
Our general dentistry services focus on preventive and diagnostic care, including exams, cleanings, and X-rays. We address conditions like cavities and gum disease using advanced techniques to maintain oral health. Patients benefit from personalized hygiene plans and early detection of potential issues.
Cosmetic Dentistry
Cosmetic dentistry improves smiles through procedures like teeth whitening, veneers, and implants. We use modern methods to correct discoloration, misalignment, and missing teeth, enhancing both aesthetics and confidence. Treatments are tailored to individual facial structures and oral health needs.
Dental Implants
Dental implants provide permanent solutions for missing teeth, combining titanium posts with crowns for natural function. Our process includes bone grafting when necessary to ensure stability. Patients regain chewing ability and confidence with results that mimic natural teeth.
Teeth Whitening
Professional teeth whitening removes stains caused by food, drinks, or smoking. In-office treatments deliver faster, more effective results than over-the-counter options. We customize sessions to achieve desired shade improvements while minimizing sensitivity.
Emergency Dentistry
Emergency dentistry addresses sudden dental issues like pain, broken teeth, or infections. We prioritize prompt appointments to alleviate discomfort and prevent complications. Services include repairs, extractions, and temporary solutions until full treatment can be completed.

Best Dentist in town. JR and his staff are amazing. I am moving out of state and I will make sure that I have a trip to Dallas every 6 mo to make sure that I keep JR as my dentist. You will not find a better more dedicated, smarter, dentist that isn't going to try and suggest unnecessary treatments. I have been seeing JR for over 10 years, the dentist I saw before JR said I needed gum grafting, JR said I was fine, we have been watching the trouble area for 10 years, it hasn't gotten any worse, and I never had to have a painful gum graft. To me that is the testament of his dedication to his patients.

Best dentist practice in the DFW! Dr. Gonzalez and his team make you feel right at home the minute you walk through the door. Your appointment time is your time and they never make you wait. They are super organized and very thorough! The staff are genuine and kind and always have smiles on their faces. I moved to Austin, yet I still try to schedule my appointments for when I'm back in town. I would highly recommend Defining Smiles - they do not disappoint!

I have been using JR Gonzales, DDS and his staff for ten years, possibly more. I drive there from far East Dallas. This is the best dentist and staff I've ever had. Everyone greets you with a smile. Cheryl, hygienist, taught me how to floss better, since I had bleeding gums. I have not had bleeding gums since. Also, there is no pain!

I have been seeing Dr. Gonzalez since he took over the practice from Dr. Goad. Couldn't be happier with him and his entire staff. He is an extremely knowledgeable dentist and has an outstanding staff. Cannot recommend enough.
