What should you do if have a cut on the corner of your mouth that wont heal?

Here are some tips for caring for a cut on the corner of your mouth that won't heal:

1. Keep the area clean and dry. This will help prevent infection and promote healing. You can clean the area with a mild soap and water, and then apply a thin layer of petroleum jelly to keep it moist.

2. Avoid picking at the scab. This can damage the healing tissue and delay the healing process.

3. Eat a healthy diet. Eating a diet rich in vitamins, minerals, and antioxidants will help your body heal faster.

4. Get enough rest. Your body needs rest to heal. Aim for 7-8 hours of sleep per night.

5. Avoid smoking. Smoking can slow down the healing process and increase the risk of infection.

6. Seek medical attention if the cut does not heal within a few weeks. See a doctor if you have any signs of infection, such as redness, swelling, pus, or fever.

Additional tips:

- If the cut is causing pain, you can take an over-the-counter pain reliever, such as ibuprofen or acetaminophen.

- You may also want to avoid acidic foods and drinks, as these can irritate the cut and slow down the healing process.

- If you are concerned about the appearance of the scar, you can talk to a doctor or dermatologist about treatment options.
