Every mouth comes with its unique set of challenges. Some individuals are challenged by irregular teeth that cause aesthetic and functional problems. Some issues are more severe than others and while many problems can be fixed simply by subtly shifting the teeth with the help of traditional or Invisalign braces, some issues require a more direct solution. Tooth contouring is the process of reshaping a single tooth or multiple teeth by subtly removing defects that may be causing issues. This procedure normally just affects the outermost layers of your teeth. There are no nerve endings or blood vessels on the outside of your teeth, so the process is essentially painless.
