Final answer:
The condition described could be canker sores, oral thrush (candidiasis), or herpetic gingivostomatitis, all of which feature white spots or plaques in the mouth that can become ulcerative and bleed. Consulting a healthcare professional is crucial for proper diagnosis and treatment.
Step-by-step explanation:
The condition described, which presents as white plaques or spots in the mouth that lead to shallow ulcers and may bleed when the plaques are removed, could be indicative of several different conditions. One possibility is canker sores, which are non-contagious mouth ulcers that typically heal on their own and whose causes may include stress, dietary deficiencies, or mouth injuries. Another possible condition is oral thrush, also known as candidiasis, which is characterized by white patches and can lead to bleeding upon removal. A third possible condition is herpetic gingivostomatitis, caused by herpes simplex virus type 1 (HSV-1), and would usually present with ulcers in the mouth and requires antiviral treatment if necessary. It is important to consult a healthcare professional for accurate diagnosis and appropriate treatment for these conditions.
