Anticonvulsant medications, such as phenytoin (Dilantin), are commonly prescribed to manage epilepsy and other seizure disorders. While these medications are essential for controlling seizures, they can have unintended effects on oral health. One of the most significant is drug-induced gingival overgrowth (DIGO), a condition where gum tissue grows excessively, making oral hygiene difficult and increasing the risk of gum disease.
At Laser Smile Solutions – Laser Periodontics & Gum Surgery, our periodontal specialists help patients from New York City, Nutley (NJ), Long Island, and Westchester manage anticonvulsant-induced gum overgrowth using advanced treatments like LANAP® laser therapy.
What Are Anticonvulsants?
Anticonvulsants are a class of medications designed to prevent or control seizures. While essential for seizure management, some anticonvulsants are more likely than others to cause gingival overgrowth. Up to 50% of patients taking phenytoin may experience some degree of gum enlargement, especially with long-term use.
Common Anticonvulsants Associated with Gingival Overgrowth
Some anticonvulsants are more strongly linked to DIGO. The most commonly implicated include:
- Phenytoin (Dilantin, Epanutin)
- Phenobarbital (Luminal)
- Primidone (Mysoline)
- Valproic Acid (Depakene, Epilim)
- Carbamazepine (Tegretol, Carbatrol)
Among these, phenytoin (Dilantin) is the most frequently reported cause of significant gum enlargement. In contrast, the others can occasionally contribute, particularly in the long term or when combined with poor oral hygiene.
How Anticonvulsants Cause Gum Overgrowth
The exact mechanism is not fully understood, but studies suggest anticonvulsants stimulate fibroblast activity in the gums, leading to excessive collagen production and tissue growth. Poor oral hygiene often amplifies the effect.
As a result, patients may experience:
- Thickened, firm gum tissue
- Gums partially covering teeth
- Plaque accumulation that promotes inflammation
- Difficulty brushing or flossing increases the risk of periodontal disease
Signs and Symptoms of Anticonvulsant-Induced Gingival Overgrowth
Patients taking anticonvulsants should monitor their gums for changes, including:
- Swollen or enlarged gums, particularly around the front teeth
- Redness, bleeding, or tenderness
- A “gummy” appearance in the smile
- Bad breath due to trapped food and bacteria
- Difficulty cleaning teeth, which can lead to cavities and gum disease
Risk Factors
Not every patient taking anticonvulsants develops DIGO. Factors that increase susceptibility include:
- Poor oral hygiene or pre-existing gum disease
- Higher doses and long-term medication use
- Genetic predisposition
- Presence of inflammation or plaque buildup
Complications if Untreated
If left untreated, anticonvulsant-induced gum overgrowth can lead to:
- Deep gum pockets and periodontal disease
- Bone loss and tooth mobility
- Chronic infections and discomfort
- Difficulty chewing and speaking
- Reduced confidence due to cosmetic changes
Early intervention by a periodontist can prevent these complications and restore gum health.
Treatment Options at Laser Smile Solutions
Non-Surgical Treatments:
- Professional deep cleanings (scaling and root planing) to remove plaque and tartar

Our team customizes treatment for each patient, ensuring the most effective solution while preserving healthy gum tissue.
Prevention and Maintenance
To minimize the risk of recurrence:
- Maintain consistent oral hygiene with brushing, flossing, and antimicrobial rinses
- Schedule regular periodontal checkups
- Work with your physician to monitor medication dosage and consider alternatives if appropriate
- Monitor gum tissue for early signs of overgrowth
Anticonvulsants and Gingival Overgrowth FAQ
Which anticonvulsant is most likely to cause gum overgrowth?
Phenytoin (Dilantin) is the most commonly associated medication. Other anticonvulsants, such as phenobarbital, primidone, valproic acid, and carbamazepine, can occasionally contribute.
Can gum overgrowth be reversed without surgery?
Mild cases may improve with better oral hygiene and adjustments to medication, but moderate to severe overgrowth typically requires professional treatment.
Is laser treatment effective for anticonvulsant-related gum overgrowth?
Yes. LANAP® laser therapy is highly effective in removing overgrown tissue while minimizing discomfort and recovery time.
Will gum overgrowth return after treatment?
If the underlying medication is continued, recurrence is possible. Regular maintenance and periodontal care reduce the risk.
Can stopping the medication eliminate gum overgrowth?
Sometimes gum tissue may shrink, but surgical or laser intervention is often needed to fully restore the gum line.
