Are you experiencing mouth sores and wondering if they could be related to psoriasis?
Mouth sores can show up for a few different reasons when you have psoriasis. Here's a quick breakdown:
Oral Psoriasis
In rare cases, psoriasis can affect the mouth, including the tongue, gums, lips, and inner cheeks. Symptoms can include red patches, swelling, and pain that makes eating and talking uncomfortable.
Methotrexate Side Effects
If you're taking methotrexate, mouth sores are a known side effect — affecting up to one-third of people who use it. One MyPsoriasisTeam member asked, "Does anyone else on methotrexate get a really sore mouth? I have constant ulcers in my mouth and on my tongue." If this sounds familiar, it's worth flagging to your doctor, as they may adjust your treatment.
Oral Thrush
Some psoriasis treatments, like biologics or steroids, can lower your body's defenses against fungal infections. This can make you more prone to oral thrush, which can cause white patches and discomfort in the mouth.
The most important step is to let your dermatologist or doctor know about any mouth sores. Getting the right diagnosis means getting the right treatment — and some of these causes look very similar but need different approaches.
