To apply for the license, please fill out the online TSBDE Dental Assistant Permit Application Form and choose X-Ray. Sixteen hours of observation with a licensed hygienist is required as part of the admission process.They may have a position, even if it's just sterilization. How and where you work today is up to you. Let your dental hygiene education and experience open doors to YOUR career path and consider the possibilities. The application for the clinical experience program is within the course. I've noticed most positions require certificates (X-ray), licenses, and school but sometimes those without experience can get hired.
