What do do when you have an itchy capalate (roof of mouth) ?

Find out why: An itchy palate can be caused by allergies, irritations or systemic illnesses. You should have your pcp or ENT look at you to help figure it out. In the meantime, keep track of the foods you eat when your mouth gets itchy.

Allergy?: You could have a food allergy or sensitivity to certain foods such as citrus or other types of spices. You should also check the toothpaste and mouth rinses you might be using. Do you smoke? I would also advise having a periodontist or your general dentist do a full exam to verify that there isn't any pathology. http://www.drgums.com.
