The colors of chewing gum are dark red and black.

1, there are many nerve and blood vessels under the teeth, which directly cause the color difference of gums. The biggest function of nerves and blood vessels is to provide blood for dental pulp, and the different blood circulation speed of each person will also make the color of gums different.

2. People with whiter skin color may also appear light pink. If the skin color is dark and the blood circulation is not enough, the gums will be dull or dark red, which is not a sign of unhealthy teeth. The gums will appear dark red, which is the product of normal metabolism. You don't have to be too nervous and anxious.

3. Whether the teeth are healthy is not judged by the color of the gums. To judge whether a person's teeth are healthy, it is mainly to observe the health of the roots and gums. If there is no swelling or cyst or atrophy of the gums, the gums are basically healthy. If there is any sensitivity or caries in the periodontal position, it proves that the teeth are basically up to standard.

You don't have to worry too much about the color and texture of your gums. As long as the gums belong to the healthy category and there is no atrophy or abscess, this is normal gums and healthy gums. The gums are purple, and even when pressed, there will be some slight pain, which should be noted, because it is likely that there is inflammation in the pulp cavity or cysts in the gums. We should go to the stomatological hospital in time to check the cause of the cyst and take treatment measures, otherwise the cyst will continue to develop and may lead to periodontitis. Common causes of gingival blackening in patients include:

1. Melanosis: The patient's gums are black, but there are no symptoms of pain and redness. This situation is generally normal and has no impact on health;

2, lead poisoning: It should be noted that lead lines will form on the gums. At this time, it is necessary to check the blood for diagnosis. If the blood lead concentration rises, it is necessary to take drugs under the guidance of a doctor and do lead discharge treatment;

3, malignant melanoma: the patient's gums are locally black, which needs to be diagnosed and surgically removed.
