Gingival enlargement, often called gum overgrowth, is a condition where the gum tissue surrounding the teeth swells and increases in size. This excessive growth, medically termed gingival hyperplasia, can result in the gums covering a large portion of the tooth crown, making the teeth appear shorter than normal. The enlargement can affect a small area or be widespread across the entire mouth. When gum tissue expands, it creates deeper spaces around the teeth, which can trap plaque and food debris. This abnormal tissue volume compromises oral hygiene and can interfere with chewing or speaking.
What Leads to Gum Overgrowth
Identifying the underlying cause is the first step in managing gum overgrowth, as the etiology dictates the treatment approach. One common cause is an inflammatory reaction, directly linked to the accumulation of dental plaque and tartar on the tooth surfaces. The presence of bacterial plaque triggers an immune response, leading to inflammation that causes the tissue to become red, soft, and prone to bleeding. This type of enlargement is reversible with professional cleaning and diligent home care, as it resolves when the irritant is removed.
A second category is drug-induced gingival enlargement, a side effect of certain systemic medications. Three main classes of drugs cause this adverse reaction: anti-seizure medications, immunosuppressants, and calcium channel blockers. This type of tissue is often firm, pale pink, and less likely to bleed than inflammatory overgrowth, developing due to the drug’s effect on gingival fibroblasts and collagen production.
Calcium channel blockers, prescribed for high blood pressure and heart conditions, interfere with cellular mechanisms in the gum tissue, leading to excessive fibrous growth. The drug’s effect alters the balance of tissue breakdown and synthesis. The severity of drug-induced overgrowth is often exacerbated by pre-existing plaque and inflammation.
Beyond localized inflammation and medication side effects, systemic or hormonal factors can also contribute. Hormonal shifts during pregnancy or puberty can heighten the gum tissue’s response to plaque, causing temporary swelling. Certain systemic diseases, such as leukemia, can manifest oral symptoms that include generalized gum enlargement due to the infiltration of leukemic cells. A thorough medical history is important when diagnosing the condition.
Non-Surgical and Surgical Treatment Options
Treatment for gum overgrowth begins with non-surgical methods aimed at eliminating the inflammatory component. Professional cleaning, known as scaling and root planing, removes hard mineralized plaque (calculus) from beneath the gum line to reduce inflammation. This deep cleaning procedure helps shrink the swollen tissues and improves the patient’s ability to perform effective daily oral hygiene.
For cases caused by medication, a non-surgical intervention involves consulting the prescribing physician to discuss an alternative drug or an adjustment in dosage. A patient must never stop a prescribed medication without medical guidance. Substituting the drug can lead to a significant reduction in the gum overgrowth over several months. This collaboration between the dentist and the physician is important for managing drug-induced cases.
When the excess gum tissue is severe, fibrous, or interferes with chewing and tooth cleaning, surgical removal is often required. The most common procedure is a gingivectomy, where the periodontist removes the overgrown gum tissue using a scalpel or a dental laser. Laser excision offers a precise method for removing tissue with minimal bleeding and faster healing time.
The objective of a gingivectomy is primarily functional, aiming to reduce the deep pockets created by the overgrowth and expose more of the tooth surface. Reducing the pocket depth eliminates areas where bacteria can thrive and allows for easier plaque removal, which is paramount for preventing recurrence. In cases where the overgrowth is extensive or involves underlying bone issues, other periodontal surgical techniques may be used to reshape the gums and bone.
Maintaining Gum Health After Treatment
Preventing the recurrence of gingival overgrowth depends heavily on establishing and maintaining a rigorous oral hygiene routine. Patients must commit to brushing at least twice daily with a soft-bristled toothbrush, focusing on cleaning along the gumline to disrupt bacterial plaque. Daily flossing or using interdental brushes is equally important, as these tools remove debris from the tight spaces between teeth that a toothbrush cannot reach.
Regular professional maintenance appointments are necessary for long-term health, even after successful treatment. These visits allow the dental team to monitor gum health, check for early signs of tissue re-enlargement, and remove any plaque or tartar that has accumulated. The frequency of these checkups is often tailored to the individual’s risk level, sometimes requiring appointments every three to four months.
For individuals whose overgrowth was caused by medication, ongoing communication between the dental provider and the medical doctor is essential for continuous management. If the causative drug cannot be changed, the focus remains on keeping the mouth clean to minimize the inflammatory component that exacerbates the side effect. Patient adherence to both the home care regimen and the professional maintenance schedule is the most important factor for preventing the condition from returning.
