hemorrhage means bleeding that occurs when a blood vessel is damaged. In dental settings, hemorrhage can range from mild gum bleeding to heavier bleeding after surgery or trauma. Clinicians use the term to describe the amount, source, and control of bleeding during care. Understanding hemorrhage helps explain why dentists focus on dryness and visibility during many procedures.
dysesthesia is an abnormal, unpleasant sensation that a person may describe as burning, tingling, “electric,” or painful. It is a sensory symptom, not a dental material or a specific procedure. The term is used in medicine and dentistry when symptoms suggest nerve involvement, especially in the face and mouth (the trigeminal nerve system). In dental settings, dysesthesia may be discussed after procedures or injuries that can affect sensory nerves.
paresthesia is an altered sensation described as tingling, “pins and needles,” burning, or unusual numbness. It is a symptom—not a disease—and it can be temporary or persistent. In dentistry, paresthesia is most often discussed when sensation changes involve the lips, tongue, chin, cheeks, or gums. The term is used in patient descriptions, dental charts, and clinical communication about sensory nerve function.
lingual nerve injury is damage to the lingual nerve, a sensory nerve that supplies feeling to the front part of the tongue and the floor of the mouth. It can change normal sensation, including numbness, tingling, burning, or altered taste. It is most often discussed in dentistry and oral surgery because the lingual nerve runs close to common treatment areas in the lower jaw. Clinicians use the term when documenting symptoms, explaining risks, and planning follow-up after dental procedures.
inferior alveolar nerve injury is damage or irritation affecting the inferior alveolar nerve, a major sensory nerve in the lower jaw (mandible). It can change feeling in the lower teeth, gums, lower lip, and chin on the affected side. It is most often discussed in dental care because the nerve runs inside the mandibular canal near common treatment areas. It may occur after dental procedures, facial trauma, or swelling/infection near the nerve.
A nerve injury is a disturbance to how a nerve carries sensation (feeling) or motor signals (movement). In dentistry, nerve injury most often refers to altered feeling in the lip, chin, tongue, or gums after dental treatment or trauma. The term is also used for irritation of the tooth’s internal nerve tissue (the dental pulp), which can cause sensitivity or pain. Clinicians use the concept of nerve injury to describe symptoms, track recovery, and communicate risk around procedures near nerves.
A radial forearm free flap is a piece of living tissue moved from the forearm to another body area using microsurgery. It is “free” because its blood vessels are disconnected and then reconnected to new vessels at the reconstruction site. In oral and maxillofacial care, it is commonly used to rebuild soft-tissue defects in the mouth and throat after disease or injury. The goal is to restore lining, shape, and function (such as speech and swallowing) as much as possible.
A fibula free flap is a surgical tissue transfer that uses bone from the fibula (the smaller bone in the lower leg) to rebuild missing jaw or facial bone. It is called “free” because the bone and its blood vessels are disconnected and then reconnected to blood vessels in the head and neck using microsurgery. In dentistry and oral surgery, it is most commonly used to reconstruct the mandible (lower jaw) after cancer surgery, trauma, or severe bone loss. It can also create a foundation for future dental rehabilitation, including implant-supported teeth in selected cases.
free flap reconstruction is a surgical method that rebuilds missing tissue by moving a “flap” of living tissue from one part of the body to another. The tissue is reconnected to blood vessels at the new site using microsurgery to restore blood flow. It is commonly used in head and neck care, including the jaw, tongue, floor of mouth, and throat after cancer surgery or major injury. In dental and oral surgery settings, it may support chewing, speech, swallowing, and later dental rehabilitation.
facial reconstruction is a dental restorative approach used to rebuild the visible front (facial) surface of a tooth. It commonly uses tooth-colored resin materials bonded to enamel and dentin to restore shape, strength, and appearance. It is often performed after decay, chipping, wear, or old restoration replacement on front-facing tooth surfaces. It can be used in both cosmetic-oriented and function-oriented dental treatment plans.
