A frenum is a naturally occurring muscle attachment normally located between the front teeth (either upper or lower). A frenum serves to connect the inner aspects of the lip to the gum. A lack of adequate gum (attached gingivae) in conjunction with a high (closer to the biting surface) frenum attachment can exaggerate the muscle pull on the gum margin and lead to gum recession. Additionally, an excessively large frenum can prevent teeth from coming together often resulting in a gap between the front teeth. If pulling of the gum under function is seen or the frenum is deemed too large to allow the teeth to come together, a frenectomy is performed to surgically release the frenum from the gum. A frenectomy represents a simple in office procedure designed to relocate the frenum back to a normal position distant from the gum margin where it can no longer cause harm.
