unfortunately thats not true. most (all?) states require you to have taken and passed a regional licensing exam (WREB's, NERBs, etc) and have graduated from a US dental school. this is my understanding
O how the under informed will speak.
Omaralt, since you obviously don't know the full rules, and they do vary by state, i will say this much:
I have foreign friends that are practicing in other states, it is called "Licensure by Credentials" and most states have these in place and they require 5 years in good standing, NBDE 1 and 2, regional board used by state or equivalent( We use WREB) and the other standard stuff.
But the kicker is this for you! because i did ask a lawyer, the states that accept states Licensure by Credentials, recognize the rules of the other state, so the states that specifically ask that the School be ADA certified are subject to a lawsuit, and this is an extremely winnable case for any adventurous foreign dentist.
Since states are very different from ADA( ADA is very powerful, but states have limited resources and burden of proof)
As the lawyer stated: "You are not fighting ADA, you are making the state """"""" prove that they are superior to California, or that California is inferior to all states that they accept licensure from credentials from, or even better the state would have to produce compelling evidence that California standards are below National Level, and this would mean $$$$ spent by the state, when the state is only interested in competent Dentists, Remember he said ADA can show a lot of years of tradition of not having schools fully accredited outside the US, but a state cannot show in the last 5 years that California is inferior"
For the Record: Personally I would not sue a state!!
But by my count when i checked this about 2 years ago, i found i believe 8 states that did not specify the school requirement in "Licensure by Credentials" it is called a loophole or ommision, and according to an attorney it is a very expandable loophole( to any state), since the burden of proof would befall upon the state in question to prove that California is inferior in Dental quality and that their licensing requirement is faulty and therefore inferior to the rest of the country, and this would mean that WREB is faulty in itself( once again $$$$$).
So when I counted it was 8 states, today it could be less, but unlikely because state legislatures would have to be addressing this specifically with prior problems from foreign flow of Dentists that are committing serious violations and affecting public opinion coming directly from California ( it is politics, so they care if it affects their reelection).
The numbers are so low of flow of Dentists to other states, that i doubt this has happened, but i could be wrong on this front, and ADA could be addressing this directly and lobbying states.
But the California bill: states that any school approved by the Dental Board is Equivalent to a California school.
So for the record before i wrote this i found 3 states that this applies to directly, for Licensure by Credentials.
Prove me wrong and research all 50 states.
BTW
Not trying to offend anyone, buy I did my homework on this subject since it affects me directly.
