The importance of tooth position

The third determinant in tooth position when we retore a smile is related to how the teeth function in speech. The sounds used for this are the “F”, “V” and “S” sounds. The edge of the front teeth should lightly touch the place on your lips where the moisture ends and the lip becomes dry with the “F” and “V”. If the lip is impinged or trapped when speaking, the teeth may be too long. The “S” sound is important for the relationship of the upper and lower teeth. If a lisp occurs, the inside of the top teeth and the lower teeth my need adjusting to allow the proper flow of air during speech.

These determinants are just guidlines. There is great variablity and adaptability in each indvidual.
