Can HS cause canker sores inside the mouth or on the oral mucosa, and can they make HS worse?

While HS itself primarily affects areas with hair follicles and sweat glands, there is a real and growing connection between HS and oral health problems worth knowing about.

Research has found that people with HS have higher rates of oral health issues overall. In one study, more than half of HS patients had at least one oral health problem. The likely link is inflammation — specifically, an immune system pathway that seems to be dysregulated in both HS and oral conditions. A myHSteam member shared: *"I recently had a situation where I had a flare-up on my lip, my gum, and my tongue."*

So while canker sores aren't a direct HS symptom, the shared inflammatory pathways may mean oral issues and HS can influence each other. It's worth flagging any mouth sores to both your dermatologist and dentist, as they can help determine the cause — including whether any HS medications might be contributing.

Good oral hygiene is especially important when living with HS to help keep inflammation in check.
