Lip bumpers are dental appliances that are used in orthodontic treatment to correct a crowded maxillary or mandibular arch. They are typically small thin wires that are covered in a plastic material and are designed to be hooked onto two "rings" (called bands) that are affixed to the lower back molar teeth. The lip bumper portion of the device sits in front of the lower front teeth and is attached via wires extending around the outside of the lower side teeth to the back molar bands.
How Lip Bumpers Work
Lip bumpers work by pushing back the lower molars牙齿, thereby widening the lower arch and creating more space for the permanent adult teeth to erupt. The pressure of the lip muscles helps to keep the lips and cheeks from exerting too much pressure on the teeth, which can lead to crowding. Additionally, lip bumpers also help to prevent lips from interfering with lower tooth alignment during treatment.
When Are Lip Bumpers Used?
Lip bumpers are most often used in cases of mixed dentition, when a child has both primary (baby) and permanent (adult) teeth in the mouth. They are typically recommended when the permanent molars first erupt and the primary molars are still present in the mouth. Lip bumpers are less often indicated in adults.
How to Take Care of Your Lip Bumper
Lip bumpers should be cleaned every day with toothpaste and a soft toothbrush, morning and night. Some patients may find it necessary to wear the bumper at night only to maintain the correction that they gained during a full course of treatment. It is crucial to take proper care of your lip bumper to ensure that it functions properly and remains effective for years to come.
Avoiding Certain Foods with a Lip Bumper
When wearing a lip bumper, it is important to avoid certain foods that can damage the appliance. These include sticky and hard foods such as caramel, taffy, and nuts. It is also recommended to cut your food into smaller pieces to avoid damaging the lip bumper.
Conclusion
Lip bumpers are a valuable tool in the orthodontic toolkit, particularly for patients with excessive overjet or a minimal amount of space in their lower arch. They provide additional space for erupting teeth and help to prevent the压力 of the lips or cheeks from causing problems for the teeth. Overall, lip bumpers are generally safe and effective when used as directed by an orthodontist.
