true, you don't have to take the ADEX in florida. But the board requires that you work full-time in Florida the first year after you are licensed (1200 hours) - with Covid-19 /offcie closures and no extension to that first year requirement, it may be tricky. We still don't know what 2021 has in store for us.
Your other option if you already have a license to practice somewhere for 5 years, then you can do public health. They are hiring for the Dept of Corrections in Florida (Centurion) but you will only get a temporary certificate and absolutely cannot work anywhere else. You will still need a full Florida license to practice outside of the Dept of corrections, jails, health departments, etc. The Health Access Dental license has also been reinstated in Florida, which is what I had at first. It is for health departments, community health centers, etc. though the pay is really poor, in my opinion and I think you have to be sponsored by the company (but that may have changed). There are also the teaching permits - but you have to be hired by a dental school (Lecom- Bradenton, FL ; UF Gainesville; or Nova Southeastern); not a hygiene or assisting school.
Those are some ways to get into Florida without stressing all at once about the boards. Once you are here in FL you can take them (when they start to offer them again to non-students). The temp certificate doesn't require anything except your current credentials but the Health Access Dental requires you pass the Laws & Rules portion and already have an active license
