A frenum (also called frenulum) is a tissue attachment that holds or connects an area such as the tongue, lip or cheek. Occasionally a frenum might be exceptionally tight, thick or short. Frenul pull can contribute to localized areas of gum recession. It can also play a role in creating gaps between teeth.
A frenectomy is a simple surgery to excise the frenum. This procedure generally takes less than fifteen minutes and has minimal postoperative discomfort.
