Pain in roof of mouth can be there because of wearing ill fitting dentures or can be there because of some infection in the roof of mouth. Nutritional deficiencies, dry mouth
and some systemic factors can also lead to pain in roof of mouth. Without clinical examination, it is difficult to give definite diagnosis. If the fit of the dentures is not correct, then denture needs to be replaced or corrected. If there is some bacterial or fungal infection
present, then treatment is required for it. You can visit your dentist
for evaluation. By the time, you visit your dentist, you can do warm saline rinses 3-4 times a day to reduce swelling. Application of orajel
over sore spots may also provide some pain relief.
