Hi, my daughter is 4 yrs and 11 months old. Last month she had a ulcer in the inner lining of cheek and lip. It wasn't very painful. Home remedies didn't work, and she got fever in 2-3 days. We visited general physician. He prescribed antibiotics and mouth paint . It got cured. As we stopped using mouth paint, the ulcer was back. Again when we started using mouth paint, the ulcer is cured. But now when we stopped using mouth paint the ulcer is back on inner lining of lip. Please suggest necessary measures. Thanks
