Mouthguards are custom-made oral appliances designed to protect the teeth, gums, jaw, and surrounding structures from injury or excessive force. They are most commonly used during sports or physical activities but are also prescribed for patients who grind or clench their teeth, a condition known as bruxism. By absorbing and distributing impact or pressure, mouthguards help prevent tooth fractures, soft tissue injuries, and jaw strain. Before fabrication, the dental provider performs an oral examination and takes precise impressions or digital scans of the teeth. This ensures the mouthguard fits securely and comfortably without interfering with breathing or speech. Custom mouthguards are significantly more effective and comfortable than over-the-counter options, which often provide limited protection and poor fit. The mouthguard is fabricated from durable, medical-grade materials and tailored to the patient’s specific needs, whether for athletic protection or nighttime grinding. Once delivered, the dentist provides instructions on proper use, cleaning, and storage to maintain hygiene and longevity. Mouthguards play an important preventive role in protecting long-term oral health. Regular use can reduce the risk of dental trauma, enamel wear, jaw pain, and costly restorative treatment resulting from preventable injuries.
