Common oral side effects from MS medications include:
* Mouth pain and sores
* Toothaches
* Dry mouth

Specific medications associated with these issues include:
* Glatiramer acetate (Copaxone) - dry mouth, bleeding gums, mouth sores
* Alemtuzumab (Lemtrada) - mouth pain, cold sores
* Interferon beta-1a (Avonex) - toothaches
* Teriflunomide (Aubagio) - toothaches

Medications used for MS symptoms can also contribute:
* Amitriptyline (Elavil) - dry mouth

Corticosteroids used during flares can increase your risk of oral fungal infections, especially with higher doses or longer use.
If you're experiencing persistent mouth pain or tooth discomfort, let your healthcare provider know. They can help determine if your medication is the cause and recommend appropriate treatment options.
