Hi,
Thank you for the query.
Based on the picture that is posted, there is mild redness but this doesnt show any indication of infection or any pathology. Such abrasions happen while eating any crisp food which can cause mild surface scratches, so to speak.
Alternatively, You can visit Oraliah Dental Clinics, Sahakar Nagar for a review and consult with our specialists.
Next Steps
Avoid touching this area with the tongue repeatedly. Kindly inform your dentist or Oral Pathologist for a consult to rule out anything else as a differential diagnosis.
