Well my place for years. From when I had insurance to losing all. They have found a way to work with me. Especially the program they offer small fee to join and good discounts. Plus they got me on since financing that worked with my income. Trust me being in pain and tolerating it to get by and being in pain for months until I just couldn’t take it anymore. Was getting sick from not eating right and didn’t know I had an infection. So came and they saw I was dealing with a lot of pain and I felt his caring the team is here and I forgot they where like this. They worked with me and got that tooth extracted and put in bone graph just in case for future if I can later on get implants. Man leaving that day without pain I had forgotten how it felt I got teary eyes Finally the pain I had gotten accustomed to was gone. Got my antibiotics send to my local pharmacy and yeah few days back for a follow up and wow lots of my problems are gone. That was in 2024. Now in 2025 I had a filling break out old filling over 10 years old. Well they saw it was starting to get infected and got on that plus again worked their magic on the bill for me and made it work yeah takes both sides to work something out and well taking stages to get a crown down all out of pocket they made it so it’s in my budget and on a limited income it can break budgets. So now after they treatment. Plan and in stages I got a crown that fits like a glove perfect no issues at all didn’t even know when it was on and am able to chew food great. The 3D scanning never had that done before and constant double check scans and u can tell work workmanship is on point. So happy I tried to get help here and will keep on coming even when it’s all out of pocket. Over all I can chewy my food again and now time to save up for my implant need to replace 3 teeth on once side. Due to chronic pain I break teeth sometimes.

What is the Mouth-Body Connection® ?


The Mouth-Body Connection® refers to the link between oral health and overall health, and the role that the harmful bacteria and inflammation in our mouths play in chronic, systemic disease. That’s why it’s time we talked about more than your teeth. Our office prioritizes your overall health as it relates to your oral health. When we care for your smile we’re also looking out for your entire self.
