Why are my gums so dark around the base of bottom teeth?

1. Gingival Hyperpigmentation

- Caused by an increase in melanin production in the gums.

- Can be influenced by genetics, certain medications (e.g. minocycline), hormonal changes (e.g. during pregnancy), or systemic conditions (e.g. Addison’s disease).

2. Poor oral hygiene

- Dark gums can be a sign of gum disease, which is caused by bacteria that build up on the teeth and gums.

3. Smoking and tobacco use

- Nicotine can constrict blood vessels and reduce the amount of oxygen that reaches the gums, causing them to appear darker.

4. Amalgam Tattoo

- When dental amalgam fillings leak mercury, it can cause a bluish-black discoloration on the gums.

5. Medical Conditions

- Certain medical conditions such as Peutz-Jeghers syndrome, Addison's disease, or hemochromatosis can lead to darkened gums.

If you are concerned about the appearance of your gums, it is important to see a dentist to determine the cause and receive appropriate treatment.
