I can tell you from personal experience that your teeth will become crooked again.
no, if you stop wearing the retainer the teeth will move back, your jaw bone dosent change!
they don't keep your teeth straight forever unless you wear your retainer after wards for a few years but if you even stop wearing your retainer for a few nights you will see your teeth starting to back to the way they were before. so orthodontists recommend wearing your retainer for at least 3 years after you get your braces out.
you will want to leave it on forever because if you stop wearing it your braces will not work and your teeth will move they can go back to normal or get worse if you don't wear your retainer
Keep wearing it as often as possible. It only hurts because your teeth have started to move. Ibuprofen works good for pain.
Only if you don't wear it often enough.
If you don't wear your retainer, your teeth won't start to shift until about a week from when you stopped wearing it.
stop wearing them
You should never take your retainer out for more than a day! Wearing your retainer everyday(whether it be daytime or night) keeps your teeth in place. Even if you go a few days without wearing one and you put it in, your teeth will feel very tight because they have shifted already. Everyday you don't have it on, your teeth move more and more. Word of advise: WEAR YOUR RETAINER!
I have to wear a retainer, and i bite my nails. Apperently you cant bite your nails when your have your retainer, but its pretty easy to. Not very hard.
Yes, you can safely eat gum even with a permanent retainer in your mouth. A permanent retainer will naturally broke after a period of time. You will have the choice to ask an orthodontist to glue it back or to live without it. Be warned that some new studies demonstrated that after many years of wearing a permanent retainer, your mandibular bone may be hurted.
You can stop wearing white pants and shoes after Labor Day.
Yes, you do have to wear wire retainers. I know because I have an overbite and I am wearing wire retainers. :) Hope this helped
