During your appointment, they'll look out for any problems and clean and polish your teeth. Sometimes the dentist will take X-rays to get a better picture of what is going on in your mouth. You also might get a fluoride treatment while you're there.
A Kite is a quadrilateral with two distinct pairs of adjacent sides which are equal. A Kite has two pairs of equal sides in which each pair must be distinct disjoint and must be adjacent to each other, sharing a common vertex. This means, the pairs cannot have a side in common.
A kite, as defined above, may be either convex or concave, but the word kite is often restricted to the convex variety. A concave kite is sometimes called a dart or arrowhead, and is a type of pseudotriangle.
