Although traditional braces are a tried-and-true way to straighten smiles, many teens and adults prefer a more comfortable, discreet solution. If you’re looking for an alternative orthodontic option, you might be a good candidate for Invisalign.

But it’s natural to have questions about this service before getting started, and many patients want to know how long it takes to complete it. Continue reading to learn more about a typical timeline so you know what to expect!

How Does Invisalign Work?

Unlike standard orthodontics, which rely on bulky metal brackets and wires attached to your enamel, this method uses a series of transparent plastic trays customized to fit over your arches like a glove.

You must wear them 20 to 22 hours a day to prevent your teeth from reverting to their starting positions; then, after about a week or two, your dentist will direct you to switch to the next pair in your treatment to account for the movement of your smile. The smooth plastic material is unlikely to cut the soft tissues inside your mouth, and because the aligners are removable, there are no dietary restrictions, and it’s easier to keep up with your twice-daily at-home dental hygiene routine. As a result, this service is often considered a less-invasive option.

How Long Does Invisalign Treatment Take?

Are you curious how long your treatment will take from start to finish? Many patients can stop wearing the trays after 12 to 18 months, but it may can vary somewhat depending on your unique circumstances.

Your dentist can provide a more accurate timeline based on your unique circumstances. For example, if you have more severe misalignments or are an older adult, it may take longer for your teeth to travel to their ideal places. Many patients also need a retainer after Invisalign to maintain results, which may need to be worn long term.

How Can I Stay On Track with Invisalign?

You can stay on track with your anticipated timeline by adhering to your provider’s instructions. For example, wearing the trays as directed each day helps prevent relapse, which can add weeks or months to your treatment. Also, cleaning your aligners as directed helps keep them in good shape and reduces the likelihood that they’ll be lost or damaged. Your dentist can order new trays relatively easily, but it still takes time.
