After realizing my teeth were failing and my senior years were destined for continual problems and big dental bills, I opted to be proactive. I chose Dr Thomas to do a complete makeover on my mouth, instead of ' death by a thousand cuts', I chose the all on 4 procedure. Expensive ..yes. An investment..yes. Worth it?... absolutely. .. I could write an entire thesis on how pleased I am with ' 'Dr T', but suffice to say... His pricing was the best, his expertise 2nd to none, and his thoroughness and follow up were great Additionally the entire staff in addition to their competence have made me feel at home. Can't say enough about my experience. It's been life changing,! Kudos to James Island Dental!

I had my teeth cleaned today and the hygienist did a wonderful job. She explained everything and put me at ease. I love James Island Dental associates . They really are very patient and understanding considering I have anxiety going to the dentist. Highly recommend and they now have an office on Johns Island . I prefer in town near the crab house .
