Change in gum colours can be caused by varied factors.
While it might not be a serious condition, various lifestyle factors have been linked to this condition.
Below are the causes as highlighted by Christine Frank, DDS, a general dentist;
1. Smoking
The tar from cigarettes can cause discolouration of the gums. Smoking cause melanosis, the morbid deposition of black matter, often of a malignant character, causing pigmented tumours.
There are certain specialized cells in the body identified as melanocytes that produce melanin. Nicotine in cigarettes trigger the production of excess melanin by these cells and this is what is believed to contribute to discolouration (melanosis).
However, the good news is that the dark patches caused by smoking can be treated.
2. Medications
Some drugs cause gum discolouration as a side effect. The common drug that has been linked to this condition is minocyline. It is used to cure acnes and certain infections like chlamydia. However, the drug has some detrimental effects to your gums. It can cause discolouration which can sometimes occur in the mouth.
If you have experienced the sign, reach out to your doctor and elucidate to them about the condition. He or she will advise you.
3. Addison's disease
The scourge affects the adrenal gland that produces various hormones. It normally interferes with the production of important hormones required in the body. Signs and symptoms of this ailment include unexplained weight loss, tiredness and lack of appetite. The condition also causes discolouration of gums.
