[|Human|] Hi doctor, the roof of my mouth appears to be yellow when I checked it recently. It as also been accompanied by swelling of one tonsil but I took an antibiotic which has made the tonsil return to its normal size. I used to smoke but Ive quit for over six months. What could be the cause?
[|AI|]  Hi. Thanks for the query. Yellow discoloration of roof of mouth is most commonly due to poor oral hygiene, oral and throat Infection, yeast overgrowth or Oral Thrush. So my suggestion is to consult an Oral Physician and get evaluated. A clinical examination and of needed a palatal swab culture can help in confirmation of the cause. For now start gargling with specialized mouthwash like Magic mouthwash. Gargle with 1:1 solution of HY Chat Doctor. . Use a soft tooth brush to clean your palate. Maintain a good oral hygiene.
