A great smile is an asset. Most people believe this to be the case, hence they go through numerous procedures just to get that wonderful smile that can impress someone or wow a crowd. No matter the reason, there is no denying the fact that a good smile is sure to be a great asset in socializing. There is something about a well-maintained smile that makes other people trust easily. It is a testament to the hygiene of the person, and in proving so, shows that the person is generally clean. From there, one can assume that a clean person is also good, as basic human instinct dictates. This is the halo effect which states that people who are more presentable are considered good, while people who are unkempt can be considered as evil.
This is where cosmetic dentistry comes in.
