Im a dental assistant level 2 should i take hygiene coordinator job?

Whether or not your work experience is seen as useful by a future employer will depend entirely on what that particular employer is seeking . The person interviewing you is the one who carries the most weight in deciding if you would be suitable for a particular job and in fact although experience and qualifications are important interviewers put just as much emphasis on the applicants attitude and personality and eagerness and appearance. So there is no way of knowing in advance how much working as a hygiene coordinator will help or not help for future job applications.
