January’s Glaucoma Awareness Month shines a spotlight on one of the leading causes of irreversible vision loss. Glaucoma is typically discussed as an eye disease, but in practice it is a long-term health condition that intersects with many aspects of daily care. Medication use, inflammation, stress response, and aging all shape how glaucoma is managed over time – and these same factors influence oral health.
Although glaucoma does not directly cause dental disease, and dental disease does not cause glaucoma, meaningful connections exist. Recognizing them helps patients navigate care more comfortably and supports better communication between healthcare providers.
What is Glaucoma?
Glaucoma refers to a group of diseases that damage the optic nerve. Vision loss usually occurs gradually, beginning with peripheral vision, and early stages are frequently symptom-free. Because of this, many people live with glaucoma for years, managing it alongside other chronic conditions as they age.
Inflammation provides one of the clearest links between glaucoma and dental health. Periodontal disease is a chronic inflammatory condition affecting the gums and supporting tissues of the teeth. While its biological mechanisms differ from those involved in optic nerve damage, both conditions involve ongoing inflammatory stress. For people managing chronic disease, minimizing preventable sources of inflammation is an important part of supporting long-term health. Healthy gums may not influence glaucoma progression directly, but they contribute to systemic well-being.
Dry Mouth, Meds and Stress
Many people with glaucoma rely on long-term medications, and some treatments are associated with dry mouth or changes in oral comfort. Saliva protects teeth and gums by neutralizing acids, supporting enamel, and helping control oral bacteria. When saliva flow is reduced, the risk of tooth decay, gum irritation, and oral discomfort increases.
Over time, dry mouth can subtly alter eating habits and oral hygiene routines, increasing dental risk if left unaddressed. Patients experiencing these changes should share them with both their eye-care and dental providers. Preventive strategies such as hydration, saliva-supportive routines, and tailored dental care can help protect oral health without interfering with glaucoma treatment.
Stress is another important consideration. Stress and anxiety can temporarily affect blood pressure and intraocular pressure in some individuals with glaucoma. Dental visits, especially longer or more complex procedures, can be stressful even for patients who otherwise tolerate care well. For those managing glaucoma, this stress may feel more pronounced.
Clear communication can help reduce unnecessary strain. Scheduling appointments at comfortable times of day, allowing breaks during longer visits, and maintaining a calm care environment all support patient comfort. These approaches benefit not only people with glaucoma, but anyone living with chronic health conditions.
Oral Care and Glaucoma
As people age with glaucoma, vision changes can affect daily oral care. Reduced peripheral vision or contrast sensitivity may make brushing and flossing more challenging, increasing reliance on adaptive tools or professional cleanings. Electric toothbrushes, high-contrast oral care products, and regular dental visits can help maintain oral health as visual demands change.
(Tip: if you have glaucoma, know that some dental procedures require patients to remain reclined for extended periods. While standard positioning is safe for most individuals, some glaucoma patients may experience discomfort or anxiety when lying flat for too long. Patients who notice dizziness, visual changes, or eye pressure discomfort in reclined positions should inform their dental provider. Simple adjustments are often enough to improve comfort.)
These overlapping considerations highlight the importance of care coordination.Glaucoma is managed over a lifetime, often with periodic medication adjustments and ongoing monitoring. Dental care is similarly preventive and long-term. Sharing accurate health information—including glaucoma diagnoses, medications, and recent changes—helps dental teams provide care that is safe, appropriate, and patient-centered.
Glaucoma Awareness Month
Glaucoma Awareness Month is an opportunity to look beyond vision alone and embrace a more integrated view of health. While glaucoma and dental disease are not directly linked, the ways they intersect through inflammation, medication effects, stress, and aging are meaningful. Understanding these connections empowers patients, supports healthcare teams, and reinforces the value of whole-person care.
By staying informed, communicating openly with your dental and eye care team, and prioritizing prevention, individuals living with glaucoma can protect not only their sight, but their overall well-being, including their oral health, now and in the years ahead.
