What Is the Cause of Gum Discoloration?

The primary cause of gum discoloration, which tends to come off as a bluish color, is typically a result of gingivitis or other types of inflammatory conditions, as reported by HealthGrades. Gum discoloration is generally accompanied with additional symptoms, like redness, swelling, pain, ulcers, sores and bleeding and the symptoms tend to worsen when eating or drinking. In rare circumstances, gum discoloration can also be a result of underlying conditions in other parts of the body, as gum discoloration is commonly associated with chronic lung diseases when the body no lingers receives a sufficient supply of oxygen.

Generally speaking, gum discoloration that is bluish in color is generally an indication that hypoxia, which means low oxygen levels in the blood, especially if the discoloration is accompanied with symptoms like shortness of breath or rapid heart rate.

If the discoloration is caused by inflammatory conditions, then the discoloration will generally happen suddenly within a short period of time; however, if the discoloration is a result of hypoxia or even vitamin insufficiency, then the discoloration will tend to take some time to develop. The course of treatment that would be recommended, and the amount of time that the symptoms may persist will be highly dependent on the underlying cause of the discoloration.
