Ok so I have been a bit confused. I mixed up dentistry with dental hygiene. Since I will be needing to go to med school what do I need to do before then?
Do you still need straight teeth for entry requirements?
It would be very hard to sit in classes knowing that everyone knows what a brace is for....
In the UK, the majority of dentistry applicants (parallel with medicine -the schools often operate as one) require basic sciences; a combination of Physics/Chemistry/Biology/Maths with an increasing acceptance of non-science qualifications.
Reading your post, I wondered if you were clear as to what your expectations from being a dentist would be. Is it the pleasure of pulling out pre-molars? In that case, being a vet might be more fun when you get extra large horse-sized monster teeth. If it's a lifestyle choice for financial security, social prestige etc, I guess any job could lead to that route.
If you have the aptitude for the American system of lengthy medical training & internship then go for it! Medicine that is. A lot of 18 year olds in England seem to pop into dentistry rather than medicine when they don't cut the grade. I guess that's probably because when we were all 5 years old, we played 'doctors and nurses', not 'dentists and dental hygienists'. Hmmm, societal shaping...
The most striking difference between being a dental hygienist and a qualified dentist (not necessarily one who does operations) is the route of training and accreditation by professional body.
Alternatively, you might try studying French to improve the grammar of your login ID ;P
Best of luck,
