The normal color of the gum tissue is pink. Gum pigmentation is caused by melanin and melanin is a natural substance in our body that we find in freckles, sun spots, age spots. It’s what makes us tan in the summertime. Unfortunately, some people have an overproduction of melanin in their gums. Discoloration may also be caused by long term use of certain medications. Now, gum pigmentation medically is not of any consequence. However, aesthetically, this could be a real challenge for some people. It makes them not want to smile at all. However, luckily, there are some things that we can do that can change that for these people and make them very happy.
