    Dr Lansdell’s office called me immediately after I requested an initial consult and cleaning via Opencare. They fit me in the same day. The entire staff at Dr Lansdell’s office were genuinely caring and easy to talk to. Dr Lansdell, himself, took his time with my consult, is a wealth of knowledge and answered all my questions patiently and informatively. I was exceptionally impressed with the entire experience

    I recently visited Dr.Lansdell because my permanent retainer placed by an orthodontist had come unglued from my teeth and had left a sharp spot in my mouth. His team was able to give me an appointment ASAP given the urgent nature, squeezing me in before their holiday break. He explained his plan to re-attach the retainer and walked me through the procedure. His team was very professional and prepped me for the procedure so that it was all done perfectly and very fast. Best of all I left no longer in pain :)
