Getting Invisalign starts with a consultation at a dentist or orthodontist who offers the treatment, followed by a digital scan of your teeth, a custom treatment plan, and a series of clear aligners you swap out every one to two weeks. The full process from first appointment to final retainer typically takes 12 to 18 months, though simpler cases can wrap up in as few as six months.
Step 1: The Consultation
Your first visit is about figuring out whether Invisalign is the right fit for your teeth. The dentist or orthodontist will examine your mouth, take X-rays, and assess what needs to move. Invisalign can correct crowding, gaps, overbites, underbites, crossbites, and open bites. If your case is especially complex, your provider might recommend traditional braces instead, though advances in Invisalign technology have expanded what it can treat significantly over the past decade.
Not every dentist or orthodontist has the same level of experience with Invisalign. The company ranks providers by how many cases they’ve completed: Gold providers have treated at least 50 cases over their career, Platinum providers 300 or more, and Diamond providers 800 or more. A higher-tier provider has seen more variations and is generally better equipped to handle tricky tooth movements. You can search for providers and their tier on the Invisalign website.
Step 2: The Digital Scan
If you’re a good candidate, your provider will create a 3D model of your teeth using an iTero scanner. This is a handheld wand that captures 6,000 frames per second as it moves around your mouth, building a precise digital map in minutes. It has largely replaced the old method of biting into a tray of putty to make physical molds, which most patients found uncomfortable.
The scan feeds into software that lets your provider map out exactly how each tooth needs to shift. You’ll often get to see a simulation of your projected results right at this appointment, showing your teeth at each stage from start to finish.
Step 3: Your Custom Treatment Plan
Using the 3D scan, your provider designs a step-by-step plan for moving your teeth into their final positions. Invisalign’s software calculates how many sets of aligners you’ll need and how long each set will be worn. Minor crowding or spacing issues might require only 6 to 9 months of treatment. Moderate alignment or bite corrections fall in the 12 to 18 month range, and complex cases can take 18 months or longer.
Once you approve the plan, Invisalign manufactures your full set of custom aligners and ships them to your provider’s office.
Step 4: Attachments and Your First Aligners
Before you pop in your first set of aligners, your provider may bond small tooth-colored bumps called attachments to certain teeth. These are tiny, nearly invisible dots made of dental composite that act like handles. They give the aligner something to grip so it can apply more precise force to teeth that need significant movement, like rotating a stubborn canine or correcting a deep bite. Not everyone needs them, but they’re common in moderate to complex cases.
Your provider will then hand you your first few sets of aligners and show you how to insert and remove them. Each set is worn for one to two weeks before you switch to the next one in the sequence. The aligners are designed to feel snug, especially during the first day or two of a new set, because they’re applying gentle pressure to nudge your teeth into their next position.
How to Wear Them
This is where your commitment matters most. Aligners need to stay in your mouth for 22 hours a day. That leaves about two hours total for eating, drinking anything other than water, brushing, and flossing. Dropping to 20 hours may still produce results, but teeth move more slowly and you’re more likely to need extra sets of aligners (called refinements) to finish treatment. At 16 to 18 hours, teeth start drifting backward between wear sessions, trays fit poorly, and delays pile up. Below 16 hours, treatment can effectively stall or need to restart.
You’ll remove the aligners every time you eat or drink anything besides water, then brush your teeth before putting them back in. Keeping your aligners clean is straightforward: rinse them when you take them out and gently brush them with a soft toothbrush. Avoid hot water, which can warp the plastic.
Check-In Appointments
Throughout treatment, you’ll visit your provider roughly every six to eight weeks so they can monitor progress and hand you your next batch of aligners. These appointments are usually quick. Your provider will check that teeth are tracking according to plan, adjust attachments if needed, and address any fit issues. If a tooth isn’t moving as expected, they may order a mid-course correction, which involves a new scan and a revised set of aligners for the remaining stages.
What Invisalign Costs
Pricing varies by provider and the complexity of your case, but Invisalign generally costs in the same range as traditional braces. Real patient examples from Invisalign’s website show doctor’s fees between roughly $5,500 and $7,000. Dental insurance that includes orthodontic coverage can reduce that significantly. Some plans cover up to $3,000 of orthodontic treatment, and in one case a patient’s insurance covered 80% of the total fee.
Most providers offer payment plans, often with a down payment followed by monthly installments spread across the length of treatment. Health savings accounts (HSAs) and flexible spending accounts (FSAs) can also be used to pay with pre-tax dollars, which effectively lowers the cost by your tax rate.
After Treatment: Retainers
Finishing your last aligner tray isn’t the end. Without a retainer, your teeth will gradually drift back toward their original positions. Your provider will fit you with either a fixed retainer, which is a thin wire bonded behind your teeth that stays in place permanently, or a removable retainer that looks similar to an Invisalign tray.
Removable retainers initially need to be worn all day and night, just like your aligners. Over time, your orthodontist will reduce the schedule, and most people eventually transition to wearing their retainer only at night. How long you’ll need nightly wear varies, but many orthodontists recommend it indefinitely to keep results stable. Skipping retainer wear is the most common reason people lose the alignment they spent months achieving.
