Bone Loss In Mouth

Hello, I'm worried because last time I went to my dentist she said I have bone loss ....
I have a misalignment of the jaw and bite, now I'm in orthodontic treatment. It was a year I wear a brace and there is one and a half to go more than a year to wear retainer 24 / 7, after which I wear all my time nightlife .
Last Saturday I went to a regular cleaning and the dentist took X-rays of my mouth and said I have a bone loss. This is not a serious matter, but I'm afraid it does not even say where in my jaw teeth??? I just know he's somewhere in my mouth. and she says she can be caused by braces is sort of normal. Today I told my ortho on the issue, she said I had bone loss before I put braces on the first X-ray shows that on which I now teach, I mean that she did not say anything in the beginning of treatment, I wonder why??? She said that anyway, because I had a misalignment of the jaw and there is pressure because of that.
So please advise me what should I do, she said she had seen before and sounded like he's not scary, but I felt like it was a serious problem, I got very very sharp teeth before treatment and now they move around a lot Although she always said it was normal, but it moves so much that I think he wants out. I'm afraid to eat anything hard not to hurt my teeth. Not all teeth are loose or worse, but there are two moving very badly
Please tell me what happens??? I'm 34, never smoked, drank at more than a few sips, not sexually active, never had children,
What can I do to prevent what is the worst case I know that insurance did not cover these problems. Has anyone experienced this? with or without treatment ortho? (Accolades )???? How can I determine the radius ex if I have no bone loss, I look at the photo, but do not get it
Thank you very much what I can do

Looking for an Xray, you will not be able to say. You have to be trained to see.

Calm yourself. Bone loss is quite normal! Especially for someone who has a misaligned jaw, then for someone with braces. When you have braces, because the teeth move because they sit in the bone. To move the teeth, bones and teeth can absorb the move. Once the movement has stopped, the bone around the teeth together.

Everyone is going to experience reverse bone. This is something that is quite normal and something you can not control. Ensure good brushing and flossing your teeth at least 3 times a day. Do not be afraid to eat certain foods, your jaw needs stimulation to maintain the bone there. If you do not use it, you literally lose.

Do not worry about it and care.

Bone loss around teeth is usually caused by periodontal disease. You can google and read all that and it should show you some X-ray showing bone loss. I would ask your dentist about which teeth are they to see the bone loss and how many mm? (This is how we measure bone loss in mm)
<3 mm is fairly healthy, 4-6mm gingivitis or mild bone loss and nothing> 6 I might start to worry. Good luck
