Tooth and Mouth Problems

Me having problem from 3 months. it comes and goes. took pain killers. but not going. what should i do now.

I have a hole in my upper right molar tooth. I don't know if I need a filling or root canal.

Actually my teeth was brown in colour , so my friend recommended the YouTube video . I watched it 2-3 times , after viewing the response of the people , I tried it . The video contains the mixture of baking soda with lemon . So after brushing for the 1st time there was some whitens but there was some blood coming between  the teeth . And the bottom layer and the top layer of the teeth turned red from black . So shall I use it once in a week or just stop using it . And tell me the best method to make my teeth white .

I had one premolar rct done 10 months ago. still there is a very very light pain . showed to several dentists . they just take the radiograph and say every thing fine . one dentist says that the obturation is short i.e not till the depth of cannal. what can else be the problem
