How long do you keep the same dressing on if you have cut your finger?

You should keep the same dressing on a cut until it becomes wet, dirty, or starts to peel off, typically changing it every 1 to 2 days. If the cut shows signs of infection, such as increased redness, swelling, or pus, you should change the dressing immediately and consult a healthcare professional. It's important to keep the area clean and dry. Once the cut has healed sufficiently, you can remove the dressing altogether.
