I think studying abroad would be an awesome opportunity! However, you are correct to be concerned about the value of the degree. We have many job seekers who have foreign credentials. Unfortunately, some end up having to take entry level positions, rather than obtaining professional jobs. There are entities that review their credentials for US equivalency. You can learn more about it at this link from the US Dept. of Education. For dentistry, go to the gray box at the bottom of the homepage, and select "Professional Recognition."
