This level of staining at this age of 29years...without any tobacco history is little strange.
The complaint you have is absolutely normal
If there's no pain or discomfort you may leave it as it is.
I suspect it to be a cheek bite because of the sharp cusps of your third molar.... ( Which has to be confirmed after clinical examination)
If so...an extraction of third molars will subside your complaint
