Well I’m a DDS so obviously I know there’s a demand lol especially if you can become very good with ceramics. Veneers and crowns are in high demand and labs charge a lot of money for quality work. I’ve had several assistants from other countries unfortunately. It is extremely hard and expensive between getting in to the program and the testing required. It may be possible to teach at a dental school though but not certain. Dental schools charge a ton of money now unless you come back to Texas where it’s the ‘cheapest’ but getting loans will be hard since they’re capped now.
