The goal of this clinical trial is to learn if a diaphragmatic breathing program can reduce sleep bruxism in adults. The main questions it aims to answer are:

Can diaphragmatic breathing lower the frequency of teeth grinding during sleep?

Can it reduce jaw discomfort and improve sleep quality?

Participants will:

Attend sessions to learn diaphragmatic breathing exercises

Practice these exercises daily at home for 4 weeks

Complete questionnaires and clinical assessments before and after the program

Participation is safe, with minimal risks, such as mild fatigue during exercises. The study will help determine if diaphragmatic breathing is an effective way to manage sleep bruxism
