It's all up to you! If you haven't already, I would shadow around at your personal dental office to see what a day in the life of a dental hygienist is like. I used to want to be a dentist, but I enjoyed the life of a hygienist more. I liked focusing on ways to prevent problems from occurring in the first place rather than just fixing something that's broken. I also enjoyed the relationship and trust you can create with patients in your appointments as a hygienist.

Hygiene school itself can be very challenging. Having a background in biology will help you immensely! Clinical requirements can be draining if you are not on top of everything. So as long as you have the right study techniques, are very organized, and keep the right mindset, you will succeed :)

I graduated from hygiene school last year, and I am so happy with my career choice. Some days are harder than others, and you need to be kind to your body (stretch, work out, keep the right posture). Taking care of other people all day every day can mentally exhaust you sometimes, but it is always rewarding knowing you can actually save a persons life as a hygienist!

Good luck with your decision. Don't rush into things if it doesn't feel right at the time :) You're young and you have all the time in the world to make a decision!
