Benzocaine won't cure the ulcer, just numb the pain. My tongue ulcers tend to last anywhere from days to weeks. You may want to see your rheumatologist, as the ulcers indicate that our disease is active. If you are having other symptoms like fatigue and joint pain, it's especially important.

Mouth sores from lupus can be really painful and make eating and drinking feel impossible — so it's completely understandable to want relief fast!
Benzocaine can help numb the area temporarily, but it's worth knowing that the FDA has flagged some safety concerns with benzocaine gels and liquids applied to the mouth, so it's best to use it sparingly and only as directed on the packaging.
Here are some other approaches that may help alongside or instead of benzocaine:
- Saltwater rinse — dissolve half a teaspoon of salt in warm water and swish for up to 10 seconds
- Cold or soft foods — these tend to be gentler on sore mouths
- Meal-replacement shakes or smoothies sipped through a straw can help keep nutrition up
- Medicated mouthwash — a doctor can prescribe one specifically for mouth ulcers
As for how long the sore will last, that really depends on what's driving it. If it's lupus-related, managing the underlying flare is key.
Since you can't eat or drink, it's really important to contact your rheumatologist soon. They may be able to prescribe something stronger to help heal the sore faster and get you back to eating comfortably.
