But I also have no teeth except for 4 on the bottom and they are rotten I am in the process of having dentures made. Also, I am on numerous medications, one being a high does of lyrica- please let me know what is attributing to these cankers
[|AI|]  Dear Sir/ Madam, There are several reasons for canker sores in the mouth. It could be, Low immunity, Heavy medications, Local infections of oral cavity, Sharp tooth etc. There are usually very painful and sensitive. It leads to a lot of saliva secretions in the mouth also. I suggest you to visit your dentist for this problem, he can guide you better.Otherwise, an ointment by the name of metro DG will help you.
