The introductory paragraph of an essay is comprised of three elements:
- the motivator, or hook, that entices the reader, arousing his/her interest
- the thesis statement, or statement of the main idea of the essay
- the "blueprint" that is an enumeration of the main points that will be presented in the essay. Each point is at the center of the topic sentence of the paragraphs of the body of the essay.
- So, the motivator of an essay on orthodontics could be a question or an observation. Anyone who has worn braces or has a family member who wears or has worn braces is aware of the pain, embarrassment, and discomfort that braces bring. Here are a couple examples:
(1)"Think of yourself as the Ugly Duckling," my brother teased me. "Right now you look like you look as though you have walked through a barbed-wire fence, but someday you will have a smile that is all right."
(2)Have you ever worn braces? Then you know the agony of being hit in the mouth by a baseball or a door. There are a thousand tears on the inside of your mouth that sting with pain. But, you endure this pain because you know that one day you will have that beautiful smile.
- The thesis statement may be about the benefits of orthodontics, how they improve a person's appearance, and how important it is that people have their teeth aligned so that they can better digest food, etc. (Doing a little research on this topic will provide points to make that are essential.)
- The body of the essay will be comprised of the three topics of the essay enumerated in the thesis statement.
To start off any essay you will need an introduction. A purpose of an introduction is to say something about the real world and transition into your essay. For an essay on orthondontics, one possible way to start is to mention maybe you or your friend's past experience with an orthondontist or with braces. Describe it in a couple sentences and then pinpoint something in your experience that relates to your argument. Once you've fixated on something, you can zoom in on it and that's when you've begun to transition into your essay/argument.
Really, you can say anything that relates to orthodontics or anything outside the realm of orthodontics but is similar in some way. But once you've said something, you need to laser point on a particular point and fixate the rest of your intro around that point so you can lead your essay to the argument.
I think you should do something humorous, such as "When learning about orthodontics, it is important for one to not bite off more than he or she can chew."
Hope I gave you a laugh!
