I see no concerns at this time. The area is where the hard palate meets the soft palate. There are some vascular (blood vessel) anatomy in the region that may be sensitive to many factors such as trauma (and or irritation), hormone fluctuations, diet, medical conditions, and autoimmune responses to new medications, toothpastes, mouth rinses, herbal, cinnamon, etc. I will be concerned if it has swelling, pain, and or irregular lesions.
