Hi there.
I think I have achieved a balance of work and study so I can reply to your question.
When I was in university I worked as a student ambassador, this part time job is not very busy in comparison, most of the time it is based on my time, I sign up for work myself, so when I have a lot of assignments I don't sign up for any work and just study at home, but when I'm busy I'm very actively involved in the activities. Although the income from this job is not as stable, I usually feel that I have achieved a work-life balance.
During holidays I apply for a more formal job, such as an internship in a company. Because I have more free time during the holidays, I spend all my time doing formal work and putting into practice all the knowledge I have learnt at university.
I think dentistry is a difficult profession to learn, so if you're willing to work at university, ask your school's career department and I think they'll offer you that opportunity. On the other hand, if you don't really want to work at university, besides asking the career department, I think it's also a good idea to ask the company directly on the job search apps, but make sure to clarify your working time with the company, such as working more on weekends, or working on the days you don't have classes, so that's a way to achieve a balanced study life and work.
These are my thoughts on your question, I hope it solves your problem.
