Brushing and flossing can remove plaque which causes calculus to form. But once calculus does form, it is too hard and firmly attached to be removed with a toothbrush. dental visits are necessary so that calculus build up can be professionally removed with sharp instruments. Source: i am a dentist
Calculus or AP Calculus
One can take a calculus course online at sites such as ProjectPolymath and StraigherLine, but one can also take a course in Calculus by going to a University (College) such as Macalester.
No. College Algebra and Precalculus (or Trigonometry) are enough preparation to take Calculus.

It depends on what college you attend. Most universities in Missouri require you to take Calculus I in order to become an accountant.
To get to Medical School, the Pre-med bachelors program usually requires that you take up until Calculus 2.
If you are pursing nursing you shouldn't have to take calculus or pre-calculus since nursing deals more with algebraic and statistical math's.
If you have the option to take Pre-Calc Algebra, do that.
No, it is not required to take calculus in high school to become a veterinarian. However, if it is an option and you have the math skills to take calculus, it will probably help you in undergraduate where you will have to take calculus and pass it to apply to vet school. Most vet schools require Calculus I and some require Calculus I and II to apply for vet school. The reason I would recommend taking calculus in high school if you have the math background is because taking it for the first time in high school is free and gives you at least some of the knowledge of the class so that when you take it in undergraduate and have to pay tuition you have a better understanding of the topic.
Calculus is commonly taken as a first year course in college, but can be taken as an advanced course late in high school through programs like AP Calculus.
Pre-calculus covers the basics you will need for calculus, including exponents, algebraic formulas and solving equations. Calculus is where mathematics and physics intersect - you can calculate the speed and velocity from a nonlinear function describing the distance traveled at a given time.
