Having a huge smile and hating my teeth was a big problem. I looked into Invisalign when I got my first 'proper' job.
The process was very fast for me from the first consultation to having Invisalign. 3 days after having my first aligners put in I went travelling for 3 weeks. This highlighted how difficult it was to be rigorous with the hygeine but it was not impossible.
Could see changes by set 3 and now on set 11 out of 18 and my teeth look and feel amazing. Still a little way to go but overall a million times better. Would recommend it to anybody who has serious image issues with teeth.
Only pain experienced is aching with a new aligner which lasts for about a day and occassionally an aligner has been rough and cut my tongue. I feel this has been made worse as I am a teacher and have to talk alot in my job!
