Mouth sores generally don't last longer than two weeks, even without treatment. If a cause can be identified, your doctor may be able to treat it. If a cause cannot be identified, the focus of treatment shifts to symptom relief.
The following strategies might help to ease the pain and inflammation of mouth sores:
- Avoid hot beverages and foods as well as salty, spicy, and citrus-based foods.
- Use pain relievers like Tylenol or ibuprofen.
- Gargle with cool water or suck on ice pops if you have a mouth burn.
