Every case is different because there are many factors that can qualify a patient for Invisalign. Invisalign is a good option for patients that want to correct crowded or gapped teeth, overbites, underbites, and cross-bites. However, age does come into play as younger patients may not be eligible due to slow teeth growth. Also, patients with dental implants, bridges, or TMJ disorder may not be the best candidates. But, as always, if you are wanting to straighten your smile, call your qualified dentist/orthodontist so they can find the best solution for you.
