Dental appliances are devices used to improve oral health and function. They can help with various issues, such as misaligned teeth, jaw problems, or sleep apnea. Common types of dental appliances include braces, retainers, and mouthguards. These devices are often custom-made by a dentist or orthodontist to fit the unique shape of a person's mouth. In addition to correcting dental issues, some dental appliances can protect teeth during sports or prevent teeth grinding at night. Wearing these appliances as directed can lead to better oral health and a more comfortable bite. Regular check-ups with a dentist ensure that the appliances are working effectively.
