What Will Influence How Much Dentistry People Are Prepared to Buy at a Particular Time?
		n The most important factor is price, the more expensive it is to buy dentistry all other factors remaining constant the less we will buy. – If price rises then the relative price changes, dentistry is now more expensive compared to other goods and services. n Economists assume that people are satisfaction     maximizers. This means that we all try to gain as much satisfaction as possible from our consumption of goods and services. So we react to the fact that dentistry is now relatively more expensive by choosing to buy less of it and more of something else instead (substitution effect).
