Reddish-blue gums
In typical cases, the color of the gums is pinkish, but colors may vary from one person to another. However, if you notice a change in gum coloring, it is a good idea to ask your doctor or dentist about your symptoms. In some cases, gum disease starts giving out subtle signs, such as reddish and even a blueish coloration in your gums. Staining of your gums is also possible as a result of acne medications and smoking, but be careful if you have darkened and painful gums with bad breath and fever, because one diagnosis to rule out is acute necrotizing ulcerative gingivitis.
