Thinking about straightening your teeth often raises 1 big question: How long will this take? At Orthodontic Smile Studio, our team knows you want a smile you feel great about, and you also want to know what the journey looks like. It’s completely normal to be curious about what you’re signing up for.

It’s important to know that the timeline is different for everyone because your treatment is designed just for you. That being said, for many people, Invisalign® treatment takes between 12 and 18 months, but some simpler cases can be finished in as little as 6 months.

Your Invisalign® Timeline & What to Expect

The First Step: Your Consultation

Your journey begins with a no-pressure chat about your smile goals. Our team uses a digital scanner to get a precise 3D image of your teeth: No need for those goopy impression trays. You can even see a digital preview of how your new smile might look when treatment is completed.

How Your Custom Plan Works

Based on your scan, a series of custom-made clear aligners is created for you. During treatment, you’ll switch to a new set of aligners every 1–2 weeks, as directed by our dental team. Each new tray applies gentle pressure to gradually shift your teeth into their planned positions.

Average Treatment Times

While treatment plans are unique, there are some general timeframes. Simple adjustments might take about 6 months to complete, but most treatments usually last between 12 and 18 months. Very complex cases may require a longer period to achieve the desired results.

Key Factors That Shape Your Treatment Length

The Complexity of Your Smile

The main factor that influences your timeline is the complexity of your orthodontic needs. Things like minor gaps or slight crowding can sometimes be corrected more quickly. If the goal is correcting your bite, such as an overbite or crossbite, the plan generally requires more time.

Your Commitment to the Plan

Your active participation plays a big role in keeping your treatment on track. For the aligners to work effectively, you need to wear them for 20 to 22 hours every day. Sticking to the schedule for changing your trays and attending your regular check-up appointments helps you progress smoothly.

A Look at Life During Invisalign® Treatment

Adjust to Your New Aligners

When you first put in a new set of aligners, it’s normal to feel some pressure on your teeth. Don’t worry: This feeling usually fades within a couple of days. You might also notice a slight change in your speech at first, but your tongue will quickly adapt. It is also important to learn how to effectively clean your aligners to maintain good oral health.

Use Attachments & Elastics

Sometimes, small, tooth-coloured bumps called attachments are bonded to your teeth. These act as tiny handles to help the aligners grip your teeth when more complex movements are required. If your bite needs adjustment, you may also use small elastics that connect the top and bottom aligners.

Simple Adjustments vs. Complex Cases

Fix Minor Spacing & Crowding

If your goal is to correct minor spacing or crowding, your treatment time is often shorter. You will likely need fewer sets of aligner trays to complete the process. This type of treatment typically focuses on the teeth that are most visible when you smile.

Correct More Involved Bite Issues

Treatments for issues like overbites, underbites, or crossbites are more comprehensive. Your plan involves adjusting how your upper and lower teeth fit together. These cases may require more aligners and attachments, and a consultation can help determine whether Invisalign® is a good choice or if braces might be better for you.

Your Most Common Invisalign® Questions Answered

How Much Does Invisalign® Cost?

The cost of your Invisalign® treatment depends on how long and complex your treatment plan is. Some dental insurance plans offer some coverage for orthodontic care, so it’s a good idea to check your specific plan. We also provide flexible payment options to help manage the cost.

What Happens After Your Treatment?

Once your teeth are in their new positions, the next step is to keep them there. You’ll receive a custom-made retainer to wear, which will help protect the position of your new smile.
