Services
Preventative Dentistry
Our preventative care program includes regular cleanings, digital x-rays, and comprehensive exams to maintain optimal oral health. We emphasize early detection of potential issues through bi-annual checkups using low-radiation imaging technology. Our hygienists provide personalized oral hygiene instruction to help patients maintain healthy teeth between visits.
Cosmetic Dentistry
We offer complete smile transformations through porcelain veneers, teeth whitening, and bonding procedures. Our instant orthodontics approach corrects alignment issues without traditional braces using custom-designed restorations. Each treatment plan combines aesthetic principles with functional dental science to create natural-looking, long-lasting results.
Dental Implants
Our implant dentistry services provide permanent tooth replacement solutions that mimic natural teeth in function and appearance. The process includes surgical placement of titanium posts followed by custom crown fabrication. We also offer implant-supported dentures for patients requiring multiple tooth replacements.
TMJ Treatment
We diagnose and treat temporomandibular joint disorders using neuromuscular dentistry principles. Our approach combines TENS therapy, custom orthotics, and computerized jaw tracking to relieve chronic pain and restore proper bite alignment. Treatment addresses symptoms like headaches, jaw clicking, and facial pain.
Full Mouth Reconstruction
This specialized treatment addresses extensive dental damage through coordinated restorative procedures. We develop personalized reconstruction plans that may include crowns, bridges, implants, and gum treatments. The process restores both function and aesthetics while ensuring proper bite alignment and long-term oral health.

Dr Pham-Nguyen is great! She's very patient with me and my questions, and super gentle, even during a tough wisdom tooth extraction. Care is prompt and equipment seems up to date; I came in with a lot of dental anxiety and Dr Pham-Nguyen has helped me tremendously. I don't know who Dr. Siles is, but I presume they no longer work at ECO Dental.

I found Dr. Siles very professional and extremely experienced in general and cosmetic dentistry. My teeth had a bite that did not line up and they were very yellow and now my teeth look great! I get compliments all the time. One of the best investments I made was in my teeth and working with Dr. Siles.

I have been a patient of Dr. Siles for over 40 years. It is my opinion that he provides the highest quality of both general and cosmetic dentistry available. I have always been very satisfied with the work he provides and would recommend his services to anyone in search of a quality dentist.

Hi my name is Tina Emmerick I started going to Dr. Siles in 2006 for a full mouth reconstruction. I suffer from Amelogenesis Imperfecta a rare disorder that doesn't allow the enamel to develop properly. It causes the teeth to be very brittle and discolored. I was very embarrassed of my teeth, and on my way to dentures at the age of 23. After researching many offices I found Dr. Siles and made an appointment for a consultation.

He has been taking care of my teeth ever since. I am very thankful to have found such a great dentist, my condition is very rare, and most dentists did not know what to do with my case. Dr. Siles has been very kind through the entire process working with me when times were rough. He has given me the smile I have always wanted, I receive compliments on a regular basis. If you are looking for a caring, professional dentist this is the place to go.

I went to Dr. Siles office for a simple teeth cleaning and possible whitening on my lower teeth. When Dr. Siles saw my teeth, he astonished me by letting me know that he could open my bite allowing me to possibly get veneers on the lowers, creating a much better smile and overall look. He was able to increase my bite and lengthen my lowers allowing me to finally for the first time show my lower teeth when I talk and smile.

It has changed the lower shape of my jaw creating a much more youthful appearance. He was able to do what my orthodontist and former dentist were not able to do. I have been so happy with the results and now I am looking forward to doing the upper teeth as well. Not only was he a joy to work with but his entire staff worked with me to ensure that I was totally taken care of. They went above and beyond what a regular dental office would have done and I am forever a huge fan of Dr. Siles' work! He is truly a master at his craft. Thank you so much to Dr. Siles and the entire staff for your dedication and care of your patients. Sincerely, Sheila Walstead
