If you're having doubts then it's better to not pursue dentistry. You really have to be pretty determined that you want it at all costs. There are a lot of other options too, not necessarily just dental hygiene. Salary aside, I think if you enjoy healthcare enough then shadow some physician's assistants, nurses, physical therapists etc. There are a lot of other options out there. You're not necessarily stuck with dental hygiene as a career. I am a dental hygienst and I do find satisfaction in my career. I enjoy the relationships I develop with my patients and want to do more for them. While my salary is good and my work schedule is even better, I'm willing to go the extra steps to be able to do more for my patients hence why I applied. Some say it's not worth it but I think it's worth it.
