Has anyone gotten their license back after letting it expire?

Mine expired about 3 years ago. I was having body pain and left dental hygiene for another field after the pandemic. However, my current field is going to be greatly affected by AI and I’m starting to worry.

I did experience chronic pain with hygiene, but I primarily worked with an older dentist who had ancient tools and supplies, which exacerbated my pain. I’m wondering if it’s worth getting my license again since there are improvements to promote better ergonomics and comfort these days. I’m also considering nursing.

I would have to take the national board and practical again. I haven’t cleaned teeth in over 6 years, so I’m rusty and behind. I know the field has advanced since I’ve left and I’m concerned I’d be clueless.

Would it be a good idea to go through a brief dental assistant course and work as one while I prepare to take the practical and national boards?

Any advice is welcome. Thank you!
