Care for the whole family

Experienced care in a brand-new home.
Landmark Dental is new to Independence County, but the dentistry is not new to Dr. Keaster. Here is what you can expect when you walk through our doors.
Twelve years of experience, now in Independence County.
Dr. Austin Keaster has practiced dentistry for over a decade in Oklahoma City. He is comfortable in every area of general dentistry, from routine cleanings and fillings to root canals, extractions and implants, so most of your care can happen right here.
Technology that makes care more precise.
We are equipping the office with tools that make diagnosis clearer and treatment more comfortable:
- Digital X-rays — Sharper images in seconds, with far less radiation than film.
- Cone Beam CT (CBCT) — 3D imaging of teeth, bone and nerves for confident diagnosis and planning.
- Intraoral Scanner & Camera — No goopy impressions, and you see exactly what we see.
- WaveOne Rotary Endo — Efficient, precise root canal therapy in fewer, shorter steps.
- Guided Implant Placement — Implants planned digitally in 3D and placed with a custom surgical guide.
A new office, built from the ground up.
Our building is going up right now on Heber Springs Road. Every room is being designed around patient comfort, from a calm waiting area to modern treatment rooms. A video walkthrough of the finished office is coming soon.
