Depending on how much time and patience you have, there are two ways to straighten teeth:
Clear Braces – for very crooked and gappy teeth. These work a lot quicker than standard train track braces and are virtually invisible. There are the Inman Aligner and Clear step systems and a new type just on the market called 6 month smile.
Porcelain veneers – for slightly less crooked and gappy teeth. Porcelain veneers will disguise worn, chipped and misaligned teeth.
