What happened to my tooth?

For background, I'm a twenty-four-year-old female with excellent dental hygiene. I always brush and floss, and have never had a cavity or gum problems in my life. I am one of those people who just have any dental problems. No plaque, no bad breath, no gum issues, no sensitivity...I've been using a Reach flosser and various sonic toothbrushes for years, and I've never used any whitening products ever because I'm worried that I'll hurt my teeth.

I've been using the same toothpaste (Crest Complete, day and night versions) and then rinsing with ACT fluoride mouthwash for years, and I wasn't consuming anything weird or acidic or otherwise bad or taking any medications. I eat a good diet, I take vitamins, and I wasn't making out with anybody who could have given me mouth herpes or something.

About a month ago, I started getting sensitivity in the upper right quadrant of my mouth and thought that I'd finally gotten a cavity, but it went away the next day and I had intermittent pain for about a week. Then one day I woke up and my mouth hurt so bad that I almost couldn't stand it, but I was broke, so I didn't go to the dentist.

One of my molars on that side -- second to the back -- was sticking out ridiculously far as if it was significantly longer than any of my other teeth and if anything touched it (including my tongue), it would hurt so bad. When I tried to floss in between that tooth and the back tooth, it took ALL of my strength to push the floss through as if that tooth and the very back tooth had suddenly become too close together. This happened literally overnight, and by the end of that day, the cheek side of my gum started hurting. I developed a sore along the top of the gum on that side that went from the back of my mouth to my incisors in about a week. It felt like an extra flap of skin and then turned into what I can only describe as a long, rectangular blister.

It hurt SO much. Seriously. It hurt worse than when I had pancreatitis last year.

The only thing I did was I kept brushing and flossing and started using G.U.M Rincinol. A week later, these blister like sores started peeling off my gum, leaving raw gums behind that healed normally. The sensitivity continued and the tooth was still jutting out too far, but now, everything is fine. It's like none of this ever happened and there's no pain, no sensitivity, no problems flossing, and my tooth is back to it's normal place.

I've googled and I didn't find anything that really sounded like what I went through.

I don't have a lot of money, so going to the dentist is something I only want to do if I'm totally screwed. The pain is gone, I have no symptoms, but I would feel so much better if I just understood what happened and if it's a sign that something else is happening that I need to get medical attention for.

Please don't respond with 'go to a dentist' as I am avoiding doing that because I'm busted for money right now and if I could afford to do that, I wouldn't be asking here.

Thank you for your time. Any advice is appreciated. :)
Update: Thank you to the first responder.

I'd like to add that I'm using Crest Pro-Health not Crest Complete. I have no idea why I typed that.

Also, I'm twenty-four as I said and according to dental x-rays I've had in the past, I have wisdom teeth, but they haven't actually made an appearance yet. I'm not sure if wisdom teeth could cause the sores in my mouth though.
