Yes, you are correct however I did not want my post to be too long. To reiterate:
Yes, I did mention that both courses will take around 5 years of university but generally, it takes around 5 years of university with an additional year of training to become a fully-qualified dentist while medicine usually takes an extra 2 for foundation plus another 5 to 8 years depending on if you intend to specialise. So generally, medicine is the longer course.
I never mentioned dentistry did not have those opportunities either. To me, I see that as a benefit in my decision process to study medicine rather than other courses. Of course with a degree in dentistry you will also be qualified to teach and all but with medicine, usually during residency you get that opportunity whether you like it or not.
My apologies as dentists are doctors in a way. They both require hands-on work and emotional connections with patients as I am aware there are many people who are more nervous going to the dentist rather than the doctors, but vice versa. I was just making a comparison with general differences that not necessarily only come from one job, but both.
Yes, the subject requirements for dentistry and medicine are similar however there are universities that require physics if you want to pursue dentistry. The IELTS requirement for dentistry is higher than medicine but for some med schools, they also consider your GCSE grades and generally require higher grades in those. Medicine is also as highly competitive of a course, if not more. You may be required to take the UCAT and/or BMAT however only some dentistry schools require the UCAT. A-level grades are generally the same.
My apologies for not being clear, hope you have a wonderful day ahead
