Do You Have Recurring Sores In You Mouth Or Tip Of Your Tongue That Gets Tender & Sore?
The most common cause of recurrent sores on the tongue is aphthous stomatitis, or canker sores. These sores usually occur one or two at a time, last seven to 10 days, and are quite painful, especially when eating acidic foods. They may recur several times a year or even every month or two. The cause is unknown but they are otherwise harmless and are not clearly associated with any single nutritional deficiency or illness.
There are some research studies suggesting that up to 20 percent of canker sores are due to lack of folic acid, iron or vitamin B12, but other researchers have been unable to confirm this. A general medical evaluation to identify one of these problems should be able to determine whether your tongue sores are related to a nutritional deficiency. In addition, it might be wise to take a multivitamin (as is often recommended routinely, even for people without canker sores).
