I’ve had a canker sore that’s turned worse and continues to bother me. I’ve been using antiseptic mouthwash and Oragel but it’s only been getting worse. Any idea what it is?
see your doctor
stop using the mouthwash if its making it worse
Gargling with lukewarm water + salt might help you. And I always apply butter which had reduced the pain and inflammation.
If you are lucky to find black nightshade (Solanum nigrum) berries in your country, you can eat those. Also their leaves can be cooked for consumption. Its a medicinal herb and is highly effective for any oral wounds.
