Myasthenia Gravis Dental Care Tips for a Healthy Smile

September 29, 2025 posted by Arabella Simmons

Living with Myasthenia Gravis is a daily balancing act, and your teeth shouldn’t be the part that tips the scale. Myasthenia Gravis dental care isn’t just about brushing; it’s about tweaking habits, talking to your dentist, and watching the side‑effects of the medicines that keep your muscles humming.

Quick Takeaways

• Schedule dental visits early in the day when energy levels are highest.
• Tell your dentist about every MG medication you take.
• Combat dry mouth with sugar‑free gum, water, and saliva substitutes.
• Prefer soft‑bristled brushes and gentle techniques to avoid fatigue.
• Carry a written emergency plan for any dental procedure.

Understanding Myasthenia Gravis

Myasthenia Gravis is an autoimmune disorder where antibodies block the communication between nerves and muscles. The result? Muscles that tire quickly and recover slowly. While the condition mostly hits the eyes, face, and throat, it can also affect the muscles you use to chew, swallow, and keep your mouth open for a dentist’s chair.

How MG Medications Touch Your Mouth

Most people with MG rely on two drug families: anticholinesterase medications like pyridostigmine and immunosuppressants such as prednisone or azathioprine. These lifesavers can unintentionally dry out your mouth, increase plaque, or raise infection risk.

Everyday Oral‑Hygiene Tweaks

Standard brushing with a hard‑bristled brush can fatigue facial muscles. Switch to a soft‑bristled toothbrush and use circular motions for 30 seconds, twice a day. An electric brush with a pressure sensor can help you avoid pressing too hard, saving energy for the rest of the day.

• Floss wisely: If hand‑flossing feels exhausting, try floss picks or a water‑flosser set to low pressure.
• Rinse smart: Alcohol‑free, fluoride‑rich mouthwashes soothe the throat and add a protective layer.
• Timing matters: Brush after meals, but if you’re taking pyridostigmine in the morning, wait 30 minutes to let the medication settle before you start.

Combatting Dry Mouth (xerostomia)

Dry mouth is the most common complaint among MG patients on anticholinesterase drugs. Here’s a quick toolkit:

1. Sip water every 15‑20 minutes, especially before meals.
2. Chew sugar‑free xylitol gum three times a day to stimulate saliva.
3. Use over‑the‑counter saliva substitutes-sprays or gels work well before bedtime.
4. Avoid caffeine, alcohol, and salty snacks, which worsen dehydration.
5. Ask your doctor about pilocarpine if dryness becomes severe; it’s a medication that can boost salivation.

Talking to Your Dentist

Clear communication can prevent mishaps. Hand your dentist a printed list that includes:

• All MG drugs, dosages, and timing.
• Any recent changes in medication.
• History of antibiotic prophylaxis if you’ve had heart valve work or joint replacements.
• Preferred appointment times (morning slots when you’re strongest).
• Emergency contact numbers for your neurologist.

Don’t hesitate to ask the dentist to adjust the chair height or provide a supportive headrest. A well‑positioned patient uses less neck and facial muscle strength, making the visit smoother.

Safe Dental Procedures for MG Patients

Procedures that require the mouth to stay open for long periods-like crown preparations or extractions-need extra planning.

• Local anesthesia: Most MG patients tolerate lidocaine well, but inform the dentist that high‑dose muscle relaxants can interact with certain anesthetics.
• Sedation: Mild oral sedation (e.g., low‑dose diazepam) can be used, but only under neurologist guidance because MG can heighten sensitivity.
• Post‑procedure care: Schedule a follow‑up within 24‑48hours to catch any unexpected swelling or choking risk.

If you ever feel short‑of‑breath or notice rapid fatigue during a visit, signal the dental team immediately. Having a written “Stop” card can be lifesaving.

When to Call for Help

Dental emergencies are more stressful when MG is in the mix. Call your dentist or neurologist right away if you notice:

• Sudden difficulty swallowing (dysphagia) after a procedure.
• Unexplained facial droop lasting more than a few minutes.
• Persistent dry‑mouth‑related sores that don’t heal in a week.
• Any sign of infection-redness, swelling, fever-in the gums or jaw.

Having a small “Emergency Dental Card” with your name, MG diagnosis, medications, and doctor’s contact details fits neatly into a wallet and can speed up care.

Quick Checklist Before Your Next Appointment

1. Confirm morning appointment.
2. Take your MG meds as prescribed, but wait 30minutes before brushing if using pyridostigmine.
3. Pack a water bottle, sugar‑free gum, and your medication list.
4. Review any recent medication changes with your neurologist.
5. Bring your emergency dental card.
