In this study, researchers are comparing two techniques for making teeth look longer and better. This is called Esthetic Crown Lengthening (ECL). Sometimes, gums cover too much of the teeth, making them look short. The study compares a new way using piezoelectric (PZ) tools, which are gentle and precise, to a traditional way called the Open Flap (OF) approach. The new method may hurt less and heal faster, but it might not always remove enough bone. The traditional way can sometimes cause gums to move back after surgery. The goal is to find out which way works best and makes patients happiest.

• The study involves a comparison of two techniques: a new gentle method and a traditional one.
• This study is for people with a "gummy smile," and it excludes smokers and pregnant women.
• Participants should expect different healing experiences and outcomes from the two methods.
