This patient wanted to straighten her teeth for years and finally made the decision to go for Invisalign! She used to wear braces as a teenager so knew what her teeth looked like when they were nice and straight! Unfortunately, she was never told how important retention is! Retention is usually done using night-time retainers or a wire on the back of the teeth. I use both!! For maximum retention. We used Invisalign over 14 weeks to get everything nice and straight again and the patient was over the moon!
