Tooth and Mouth Problems

I want to go undergo Whitening Treatment. I need results in 7 to 8 days max. I am confused if I should go for Zoom Teeth Whitening or Home Trays. The problem with Zoom Teeth Whitening is that I may get sensitivity and Pain or Gums problem or any other future problem. I am also not sure if I can sit through 1 hour treatment peacefully. Home Trays is relatively safe and risk free as per my knowledge but it gives results only after 12-14 days. I have sometimes bleeding problems in my gums. I don't smoke or take tobacco or take dark color drinks like cofee or tea. My current shade is D1 or D2 and I want A1-A2. Pls suggest. I am 32 and male.

I've been seeing a lump yellowish-red in color developing above the toung area or floor of the mouth, for few hours and going away sine last 2 years or so. It mostly forms when i usually eat a bit spicy or masaaledaar food, although i hardly eat spicy food but sometimes it appears while having less spicy food with any kind of cold liquid like soft drink, lassi etc...It's painful while eating but as soon as i'm done eating, it goes away automatically and doesnt pain later at all. I did have my rct and discussed with dentist but he didnt say any thing. Yesterday it appeared again while having dinner and i touched it and it bursted and now it remains yellow dot and pains. Is it a sign of any thing serious? Who do i get consultation from? Thank you!
