Breaking the Habit: Understanding and Correcting Lip BitingDo you or your child struggle with a chronic lip biting habit? It is a common issue, but from an orthodontic perspective, it often brings up a classic “chicken or the egg” dilemma. Does lip biting cause poorly aligned teeth, or do misaligned teeth trigger the habit?According to orthodontist Dr. Amanda Wilson, the answer usually points to a dental condition called overjet. Overjet occurs when the upper front teeth protrude too far forward horizontally over the lower jaw. When this gap exists, the lower lip naturally rests behind the front upper teeth, paving the way for a constant lip biting cycle. In these instances, fixing the bite is the key. By correcting the overjet and properly moving the teeth, the subconscious urge to lip bite generally disappears on its own.However, not every lip biter has an overjet. Some patients present a perfectly normal bite but still struggle with a chronic, repetitive habit. For these unique cases, specialized dental appliances are highly effective. Orthodontists frequently turn to a tool known as a lip bumper. This device utilizes small molar bands combined with a slim wire bow that sits directly in front of the lower teeth. It works by removing intense muscle pressure from the lips and cheeks, blocking the physical habit entirely while safely protecting the dental arch.For patients dealing with both jaw misalignment and spacing issues, a custom approach is best. Treatment may involve a specialized plan to help grow the lower jaw forward while closing up any spacing or gaps at the top.If you notice a persistent lip biting habit, a quick consultation with an orthodontist can identify the exact structural cause and deliver a personalized, comfortable solution.
