I got my braces sometime this year in March (I think?) on both bottom and top teeth. They were red and light blue (there weren't many nice colours to pick) when I got them, now they're just light blue. Personally I would've liked 'teal' if that colour was available.
I didn't have too much pain, but my teeth were tender until I got them tightened 6 or so weeks later. It's probably because my teeth moved slowly- causing less pain, I suppose? My teeth were looking straight in just 3 months after getting them, amazingly! The only problem for me now is I keep biting one of the brackets off my tooth and my dentist comes once every 2 weeks so I have to wait a bit until I see him next.
I've put my braces on Friday. They have no color, but if they had I'd pick green xD. I mean it's still weird to use the braces. Lots o' pain in the teeth & bit my mouth because of that ;-; I only have braces on the superior teeth, will put on the inferior in Christmas. Wondering how will the pain be when I put them.
Can't determine how much pain you'll get but I would say it depends on how crooked your teeth are. Considering you don't have braces on your inferior teeth then you will probably receive around the same as the superior :\
Just stick to cold drinks to help numb the pain and eat soft foods and you should be fine. I drank custard and ate mashed potato and veggies for about a week xD Every night I rinsed my mouth with warm salt water to help with the pain and healing -considering I had four teeth removed for braces.
There's still a bit to go until Christmas so I wouldn't be worrying about it, I wish you all the best though
