Frenectomies are done for various reasons. Most commonly they are done to stabilize the position of the teeth. When a space naturally occurs between the upper incisors, the frenum can prevent the space from closing spontaneously. If the space is closed orthodontic ally, the frenum can cause the space to reopen. In these cases, the frenum is removed to stabilize the tooth's position.
The frenum, when attached to the gum at a level close to the tooth, can cause a pulling on the gum margin and create recession. In this case, a frenectomy is done to prevent recession and is commonly done in conjunction with a gum graft.
The frenum under the tongue can cause problems if it is too short. It causes a situation called lingual ankylosis or "tongue tied". If the tongue is restricted it can interfere with speech and the proper eruption of the lower teeth. A frenectomy can be done to release the tongue and allow it more freedom.
The frenectomy is a minor surgical procedure done with local anesthetic. The entire procedure only takes a few minutes. Activity afterward can continue normally and usually does not require anything more than a Tylenol. The only restriction is to be careful when eating. Stay with softer, cooler, non-spicy foods for the first day or so.
A fiberotomy is a minor surgical procedure usually done by a gum specialist where the transceptal fibers are excised just below the gum tissue between severely rotated teeth. The transceptal fibers are small fibers that connect the teeth to each other like a rubber band.
When teeth are straightened, their fibers are stretched and have tension placed on the because of the new position of the teeth. There is a constant tension on the fibers to return to their original position. This, of course, can contribute to rotation and separation of teeth following orthodontic treatment. If the fibers are relieved, then the body lays down new transceptal fibers, thus making the teeth more stable in their present position.
A fiberotomy is a surgical procedure done with a local anesthetic where a small instrument is placed under the gum tissue and not through it. The incision occurs around the tooth. The entire procedure only takes a few minutes. The gums around the teeth are sore for a couple of days, but it does not prevent the patient from continuing normal activities. An aspirin or Tylenol is all that is required afterwards.
