I am a foreign trained dentist, been here in the USA for more than 6 years ( US Citizen) working as an RN I have been contemplating of going back to my first love.. dentistry. I am in my mid 40s , family. Can someone here tell me is it too late ? - considering my age to pursue my dream . I can see here how competitive it is to get into residency, I wonder if age would be a big issue for me to be accepted. Also, can someone give me a rough estimate how much it would cost to do the residency. I hope someone here will answer, am desperate for input. Thank you.
