White, swollen gums can be the result of gingivitis, wisdom teeth pericoronitis, or irritation from bad restorations, and should be examined at your local healthcare facility for the exact cause. Normal gingiva should be pink in color, firm in texture and thin in form. 1. When oral hygiene is poor, it can lead to the formation of plaque and calculus, which can stimulate the gums to produce inflammation, resulting in the gum color to become dark red or partially white, the disappearance of spots, and soft texture. 2. When there is wisdom tooth pericoronitis, if the wisdom tooth is not in the right position or if there is mental tension or stress, it will lead to redness, swelling and even whitening of the gums around the wisdom tooth, which will cause pain. 3. If there are bad restorations in the mouth, the edges of the bad restorations will press on the gums, resulting in whitening of the gums under pressure, which will result in swelling over time. Gums white swelling may be a physiological phenomenon, but also may be a symptom of certain diseases, such as gingivitis, wisdom teeth, pericoronitis, bad restorations, etc., should be timely consultation to find out the cause of the disease.
