Hi Beth,
Thank you for your complement. You should totally ask what your options are. I'm sure that if he needed to use ligs or powerchains, and they were badly stained, I'm sure that you can go in and have them changed. I've seen patients at my ortho's office come in to have them changed out.
I am indeed a TMJ patient. I did have some minor relaspe though. My bite is my main problem. But when I went in for my initial consult, everything that the ortho said made sense! I did have a car accident 16 years ago when led to back, shoulder and neck problems. I was being treated for myofacial pain syndrome. I was reading many years ago that it could lead to TMJ issues. I did go through a very stressful period in my life which started about 4 years ago with my now ex-husband and I truly believe those issues aggravated the TMJ as well.
As far as extractions go, are your wisdom teeth inline or impacted? After my first ortho treatment was completed, my ortho said that mine will most likely need to come out even before they came in. I did have them removed almost 6 years later (they were all impacted) No biggie! I have crowns on my lower left first and second molars, the first one had a root canal and it has a molar tube on it and so far so good, no issues, but I had an inlay in that tooth initially and I ended up fracturing it and their was no way of it being saved and my old dentist thought that it would be a good idea to do a profalatic (spelling) root canal, he was worried about exposure at the time. Almost 3K later, and 2.5 years later, no problems!
Don't be scared, you've been down the braces road before and things have changed so much! I've been told that there is no guarantee that this will work, but I'll have much better function. I was grinding my teeth and I would rather try and have some pain relief and save my teeth from any more future damage.
In the last 11 weeks, my teeth have changed so much, I don't regret anything. Just go for it!
BTW, I read your story and I'm a fellow North Jersey girl too!
