St. Louis RDHs — we're hiring!

SmileWell Dental, my privately owned practice in South County St. Louis, is looking for a Registered Dental Hygienist — full-time or part-time.

I'm looking for someone who loves patient education, prevention, perio, and understanding the why behind what we're seeing clinically.

We're a wellness-focused practice and use technology including digital radiographs, AI-assisted radiographic review, iTero scanning, intraoral photography, guided biofilm therapy, and salivary/oral microbiome testing.

More than anything, I want someone who is thorough, curious, dependable, communicates well, and wants to be part of a small team providing really comprehensive patient care.
$55–$65/hour depending on experience and fit.

Experienced hygienists are welcome, but I'd also love to meet a motivated newer graduate who wants to learn.

If you're interested — or know someone who might be a great fit — please message me or apply at https://smilewellstl.com/careers/
