Good evening sir I fairly understand your concern, but, you have to be more precise as to where exactly you are experiencing red and white spot. Nevertheless, considering your problem regarding you rear, right bottom tooth, it seems to be partially erupted and the tooth just above it may be causing recurrent friction in your gums, which may be one of the reasons of that red and white spot you are experiencing. If that is what the case is, then you must get rid of your last tooth and the tooth just above it, and you will be free of the pain and red and white spot, if that is not the case then in my opinion you must consult a dentist nearby you, and I am sure he will help you
