Invisalign Treatment
Invisalign uses clear, removable aligners to straighten teeth discreetly. This treatment is ideal for patients seeking aesthetic alternatives to traditional braces. Our certified providers create customized plans using SmartTrack material for precise tooth movement.
Braces
We offer traditional metal braces and clear braces for effective teeth alignment. These fixed appliances address complex bite issues and are suitable for patients of all ages requiring comprehensive orthodontic correction.
Diagnostic Records
Comprehensive diagnostic records including digital X-rays, photographs, and impressions help create personalized treatment plans. These records ensure accurate assessment of dental structures and jaw relationships for optimal treatment outcomes.
Retainers
Custom Vivera retainers maintain teeth alignment post-treatment. We provide both removable and fixed retention options to ensure long-term stability of your corrected smile.
Emergency Orthodontic Care
Our practice offers after-hours emergency support for urgent issues like broken appliances or severe discomfort. We provide immediate guidance and prompt repairs to maintain treatment progress and patient comfort.

Dr. Bogle and her team has provided excellent service for me over the last two years. I am very happy with the results. Actually I never thought such improvement would be possible as my bottom teeth were so bad and I started my braces when I am 32 years old. I cannot express well enough how grateful I am to Dr. Bogle and every one in her team. They are amazing people who are always so kind to me, very patient with my broken English, caring about my feelings. I love my beautiful teeth now. They have instilled me with confidence and provided me a wonderful smile.

I can speak from much experience with Dr. Joe Giordano. With over 40 years experience as a hygienist, and seeing the outcome of many of his cases and that of my own children and now grandchildren, he is first on my list of orthodontists. He and his staff are kind, caring professionals.

I am an adult patient and in the middle of treatment with Dr. Giordano. He goes above and beyond in his treatment plan and even conferred with my dentist before he began. He and his office staff are all terrific and make the experience easy. Grade A+!

Dr. Giordano is awesome. He has done a great job on both of my kid's braces and he is very concerned about how they are doing after visits making sure they are comfortable. He has eve called our house to see how they were doing on multiple occasions. A+ highly recommended from me. Thank you Joe!
