I could use your advice. Here goes.
1) I'm 36, almost 37.
2) Had metal braces when I was a kid for an overbite, between 6th-8th grade, then no problems until I turned 32. At that time, I noticed I was inadvertently biting the corners of my mouth. I consulted my dentist. He said it appeared my overbite has slightly returned but there wasn't anything to do about it because as an adult I wouldn't want to go through braces.
3) The mouth biting stopped and experiencing no problems, I didn't raise the issue again.
4) 4 years later, in June of this year, 2015 my dentist was examining me and on his own informed me that my bite was looking like it was getting to the bite where I might want to consult an orthodontist.
5) So I did. The orthodontist said a) my overbite has slightly returned. b) there is some slight spacing on the sides of my teeth and c) there is what he called crowding - i.e. one of my front bottom teeth is pushed back more than the others. Fun fact - this was due to a mistake made by the orthodontist I had when I was a kid. It wasn't the best looking but it never really caused me a problem and isn't that noticeable so I never worried about it.
6) The orthodontist (the one I saw this year) told me that my problems were all minor and that for me, Invisalign would be "optional." He further went on to say that if I wanted to go through with it, it would bring me some improvements. However, should I decided that at this age I don't want to bother with it, he would not be worried about the health of my mouth/teeth. I questioned him further, asking well do you think if I let it go now, will I end up with serious problems in the future i.e. will I end up as a bucktooth beaver or something and he said no. I could take it or leave it, either way I'd be fine.
7) He gave me the option of having my teeth photographed for the insurance and I did that. Luckily, due to a recent job, I have great dental insurance. I was informed I'd only have to pay $1,200 which though a lot, is not much compared to some of the other figures I've heard people having to pay.

9) As the summer went on, I did more research. I read horror stories. People who have gotten invisalign and lost teeth. Cracked teeth. Ended up with teeth looking worse than they ever did before after spending tens of thousands of dollars on attempts to fix the problem.
10) So I've been panicking for quite some time now. When I look at my teeth in the mirror, I don't see a freak or anything. It would be nice to fix that one pushed back tooth, however, I am reminded that tooth was not that way before I had braces as a kid and ended up that way as a result of orthodontics and thus it dawns on me I can live with that tooth or I can run the risk of developing a problem ten times worse.
11) I'm older. My teeth aren't as strong as they were when I was a kid. There are a couple where I can feel some clicking going on, possible warning sign they are getting loser. My dentist has given me that periodontal pocket test and I've gotten some lousy scores. Admittedly, that was due to a period when I didn't take very good care of my teeth i.e. not brushing regularly etc. The dentist lectured me, scared me straight and I became an adamant brusher/flosser ever since.
But I have read that invisalign has the potential to damage/shorten your tooth roots and doesn't that pocket test mean I'm going into this with short roots already?
Maybe I'm a wuss but the idea of risking tooth loss for something described to me as "optional" makes me worried.
12) This is not me being down on myself. It's just reality. I'm an ugly person. I accept it. I'm used to it. Thus, if I do need orthodontics, I wonder if metal braces would not be better than invisalign. Bottomline - I'm not like a handsome prince worried that his perfect appearance might be flawed by a little metal. At this point, that metal would be one more ugly added to a pile of ugly. Who'd notice?
13) I am badly overweight, to the point of it being a serious health problem. I've struggled with it for years, unable to do anything about it. Thus, part of me wonders if getting invisalign would not be worth it for no other reason than it would become so difficult to eat between meals what with all the brushing required that it would stop me from all the in between meal snacking that gets me into trouble.
I know. That is a dumb reason to get invisalign.
14) I paid $1,200 up front. I postponed my date to get the invisalign put into my mouth because I went on a vacation and figured why not enjoy my vacation and then have it done. Honestly, I was relieved to put it off for awhile too.
15) But now I have to make a decision. My appointment to have it put in is this Friday. I already paid $1200. I assume if I cancel I will lose a big chunk of that which will suck but then again if I don't need it I suppose it's better to lose money than to take on unnecessary risks.
16) But I'm also worried - this orthodontist, from what I can tell, appears to be very competent, knowledgeable and caring. Should it ever be determined that I develop a serious problem that MUST be treated and is NOT optional, he's the man I want doing it. So I fear by canceling on him now, I end up burning a bridge if I find I require his services in the future.
17) I know he said he didn't forsee my teeth becoming a problem so perhaps I should not worry about that.
18) I read you have to wear a retainer for life. I never knew that. The orthodontist I had when I was a kid never told me that. He gave me a retainer and had me come back for awhile. Eventually, my mom told me your teeth look fine and I'm not going to pay that orthodontist anymore he's just milking it so I said what the hell mom knows best and never wore the retainer again. Apparently, I was supposed to.
At any rate, I haven't worn a retainer since 8th grade and don't envy the idea of being committed to one for life.
So to boil this longwinded rant down, my worries are:
1) I'm told its optional so why take on so many potential risks for optional treatment.
VS.
2) Though the ortho said he doesn't forsee my teeth developing future issues...since I have a) gotten insurance approval b) already paid c) had molds of my teeth made - should I just go through it now to avoid the chance of say, at 45 my teeth become a mess and I end up wish I'd done it when I was 37?
My appt is this Friday so I just have to make a decision and stick with it. Your input is appreciated. Apologies this is so long.
