Is dentist student loan refinance worth it right after graduation?

I just finished dental school and I’m trying to figure out if refinancing my student loans right away is actually a good idea.

I’ve got a big chunk of federal loans and I’ve been seeing refinance offers for dentists with lower interest rates, but I’m not sure if it’s too early since my income is still new and not super stable yet. I also don’t want to lose any federal protections if I refinance too soon.

I’ve checked a few rates online but it’s still a bit confusing.

Is it worth refinancing right after graduation or should I wait a few years first?
