Patients that show a lot of gum when they smile often don't have much confidence in their smile.
This can be corrected via a number of different means. If you have a gummy smile the extra bit of gum on show might mean that you've got proportions of your teeth which are incorrect.
The teeth can be lengthened by a procedure called crown lengthening surgery.
This can be discussed in more detail depending on a full clinical assessment.
