Hi, understand your concern.
Melanin pigmentation is responsible for this color of your gum, which is a natural pigment responsible for color of our skin too.
Sometimes, harmonal changes or smoking (not applicable to you) can cause this.
It's natural and can be lighten by laser therapy, only if aesthetic is real issue .
Oral ulcer is seen on lower lip, that might cause discomfort . But dark gums no problem health wise.
Can see a dentist for regular check up and cleaning of teeth.
