Mouth Diseases

Tongue sores



When I eat different types of fruit - watermelon, tomatoes, oranges, etc. - I develop sore spots on my tongue. It almost looks like these spots are raw and exposed. Is this an allergic reaction to certain foods or does this indicate something more serious? I would hate to give up fruit in my diet, is there anything to take to alleviate the symptoms?


It is unlikely that this is an allergic reaction because the fruits are so different. The sore spots could be any one of several conditions, but probably the acidic nature of the fruits is bringing the sore areas to your attention, rather than actually causing the sores. If the problem continues, you may want to be seen by an oral pathologist. No treatment can be recommended without a firm diagnosis.
