A 94 year old lady is very desperate in finding something to help her. She has sores on her tongue, she has had them for a spell. In 2009 she had surgery on it. They said they would not come back, but they have. She has tried Activia yogurt, and it has lactic acid, so she stopped eating it. Her son has brought her medicine from his dentist and she can't afford a specialist. Please can you suggest in what to do?
