1. Your gums may bleed a little the first night. I didn't expect this, so it freaked me out a little, but.. it is normal. It happened to me that first night I wore my first trays, there was some in the morning in my trays when I took them out for the first time.
The second night your gums would settle.
2. Get ready to commit. You may think you are taking the easier solution to straighten your teeth instead of braces, but it may not be. Are you really ready to truly brush, floss, and rinse EVERY time you eat and faithfully put your trays back in OR so forever hold your peace lol? Or would already attached braces be easier?
3. The number of trays they say you need will probably not be accurate. The last 3-4 trays may just be extra. But depending on how committed you are to wearing your trays will determine if you have to go through the Refinement Process. You may HAVE another whole set of trays to wear after the first, and maybe a third set if you are bad at wearing your liners like your supposed to, at least 20 hrs. a day.
4. The Refinement Process: You'll have new pictures/video taken with that weird computer camera stick. Keep in mind those attachments you had glued on in the beginning will have to be all the way sanded off and new attachments will have to be put on.
5. You will have a lisp for a while when you talk. Singing may be interesting too. You may want to think about this for those who have jobs that require important phone conversations. I had to leave voicemails at work for people and always felt a bit awkward leaving messages. You do at some point learn to talk again without the Lisp, but everyone is going to be different. Of course you could take the trays in and out to do that but guaranteed your going to get tired of that.
6. You may need some teeth shaved. I still can't believe i calmly let my Ortho shave my teeth . AKA 'polish. It wasn't as bad as I thought it would be. Praise God.
7. They are invisible.. But not completely invisible. Your family and people close to you will notice. They may be afraid to tell you.. Or not.. But your mouth movement while talking will give it away. If that matters to you. You also don't know where you attachments will be. Prayerfully they won't be right on your front 4 teeth. Some people get blessed with needing less attachments.
8. Your attachments may be sharp at first. Some of them are more triangular shaped and are sharp for the first few days. (When your trays are off). You might want to be careful sneezing because it sure can hurt. Praise God you do finally get used to them.
9. You could lose weight. Especially if you don't want to do #2 above after every snack lol. You will plan out your food better or just decide not to eat that extra snack because you don't want to hassle with it.
10. You may want to put away the lipstick for a while. Or look for a 24 hr. wear one that wont rub off on your liners. My goal was to wear lipstick after this journey was over. I promised my daughter I would once my teeth were straight.
