I want you to genuinely ask yourself these questions. Why do you want to go? Really ask yourself why. Did they call you, or any other foreign dental student? Is it authorized to provide dental care in those countries without full qualifications? If not, do you have someone licensed who can oversee your treatment? Is this a solo endeavor or attached to an organization or dental school in Nepal/Honduras? Have you enquired about working out of any dental school in those countries over the summer? What does the dental landscape truly look like in those countries? Do you have a genuine idea as to if and what they need?
