hey all, I have 3 crooked bottom teeth in the front, and 1 crooked tooth in the back row. This is because I didnt wear my bottom retainer for some time after i got my braces. The rest are straight, because they (thankfully) stayed in their place. I am going to the orthodontist to get it checked out pretty soon. should I ask her about invisalign? Does it sound like I could use it? How long do you think itw ould take just for the bottom teeth described?

Invisalign was initially created to deal with orthodontic relapse, meaning cases which were similar to yours. When you have your orthodontic assessment, the orthodontist will tell you your options and let you know if you can have Invisalign. Most Invisalign cases are completed in 9 months to a year.
You can do a self-assessment at their website to see if you think it fits your lifestyle.
