It’s too early for us to know how PSLF is going to work out. In general, there are few jobs that qualify for PSLF for general dentists, and even fewer for specialists.
Most OMFS are not employed full time by a 501c3. And honestly, they don’t need PSLF. Most will refinance their loans even if they’re looking at 600k.
For those that are planning on PSLF but have not worked yet. They may be underestimating how difficult the workday can be for a general dentist at a 501c3. Some of the jobs will be fine, but many will be high volume, heavy workload days. Doing that for 10 years full time may very well destroy your body and shorten your career.
