Good day

Are you a smoker or do you chew tobacco? Did you put any medication onto your gums in the affected area?
This could be a leukoplakia. To find out if this is sinister or not, a biopsy needs to be taken of the affected area.

Thank you for your reply
No I’m not a smoker and do casual drink once and awhile nothing major, the only thing I’ve done in that area is I get food stuck in between those teeth and I pick at it with a wooden toothpick for very long time and it usually till it starts to bleed
Is it normal for that molar to turn black under the crown? I never seen that till I took those pictures..

Thanks
