Hello,
Your gums look complete normal. The white deposit you talking can be plaque or calculus that deposit on bottom of teeth and tooth cleaning is recommended twice a year in every 6 months.
For the problem of 46 if that's only tooth that hurts then go for re RCT or check for tapping sound in the tooth adjacent to it that is 45.
The jaw pain can be due to teeth but then for your satisfaction you can get jaw examination for tmj problems.
