<s>[INST] I have been treated by my dentist for 4 weeks now for an extremely sore palate . She tells me taht she sees my palatal rugae are inflamed but that there is no sign of specific ulceration/ broken skin but has treated me unsuccessfully for bacterial/ then fungal and finally steroid lozenges to no avail!! Nothing is working. She has also cured my gingival bleeding condition and instilled me with better oral hygiene measures - using interdental brushes and corsodyl but my palate is still agony. She thinks it might eb an allergy but what do you think. Its soooo painful!!! [/INST] Hello, Thanks for writing to us. Soreness on palate can be due to-1. Denture dermatitis caused due to dentures or appliances inserted.2.abscess developed due to spread of infection into periapical area through deep caries or periodontal infection. I would suggest you to get a thorough clinical evaluation done. Discontinue use of appliances or dentures causing allergy. Pus if present has to be Chat Doctor. Take care. </s>
