PAINFUL SORES IN THE MOUTH FROM MULTIPLE CAUSES
Mouth Sores
Painful sores in the mouth caused by infections, trauma, deficiencies, autoimmune conditions or systemic illness. Most heal within 1–2 weeks; persistent sores need careful evaluation.
ABOUT THIS CONDITION
What are Mouth Sores
Mouth sores are painful lesions that develop on the inner lining of the mouth, including the gums, tongue, cheeks, lips and palate. They can result from a wide range of causes including local trauma (such as biting the inside of the cheek or rough dental work), viral infections (such as herpes simplex), bacterial or fungal infections, vitamin and mineral deficiencies (particularly vitamin B12, folate, iron and zinc), autoimmune conditions, food allergies, certain medications and systemic illnesses. Typical features include painful round or oval ulcers, redness around the sores, difficulty eating and drinking, and sometimes fever or swollen lymph nodes. Most mouth sores heal within 1–2 weeks with supportive care. Persistent, recurrent, large or unusual sores need careful evaluation, particularly in smokers or those with risk factors for oral cancer. Dr. Patnam Pravallika Reddy provides accurate evaluation and treatment at Lux Hospitals, Hyderabad.

Identifying the Underlying Cause
Careful evaluation determines whether the cause is local trauma, infection, deficiency, autoimmune or systemic — guiding targeted treatment.
Topical Care for Symptom Relief
Topical agents help reduce pain, support healing and protect the sore from further irritation.
Treatment of Deficiencies
Iron, vitamin B12, folate or zinc supplementation is given when deficiencies are identified.
Antiviral or Antifungal Therapy When Indicated
Specific antiviral or antifungal medication is used when herpes simplex or oral candidiasis is identified.
Dental and Specialist Referral When Needed (Referral for dental / ENT evaluation)
