Invisalign Process: Each Stage From Scan to Retainer

The Invisalign process starts with an evaluation and a digital scan, followed by a plan for moving your teeth with clear, removable aligners. You wear each set for about one to two weeks, usually 20 to 22 hours a day, with progress checks during treatment and retainers afterward to hold your smile.

For a working adult, the biggest commitment is the daily wear schedule, not the scan. At Markowitz Orthodontics, we offer Invisalign and iTero digital scanning in Blue Bell and Lower Merion. Choose the office that fits your work or school routine, and bring your scheduling questions to the consultation.

How does the digital scan replace molds?

An initial evaluation may include X-rays and photos as well as a digital scan. Our iTero scanner captures a 3D image of your teeth and gums without traditional impression trays, a welcome difference if you dread molds.

The scan itself takes only a few minutes, and you can see the image on screen. Ask how the first tray change will fit into your week, then confirm the expected check-in schedule. If work trips make appointments difficult, discuss that before treatment begins.

What do you review on the treatment plan screen?

Invisalign planning uses ClinCheck software to map tooth movement stage by stage. The screen can help you understand which teeth need to move and how those movements work toward the planned result.

Ask how many stages the plan includes and what happens if a tooth does not move as expected. The simulated final result is a target, not a promise. Actual movement depends partly on how well the aligners fit and how consistently you wear them.

Your plan may include interproximal reduction, or IPR, a small removal of enamel between teeth to create space. Before agreeing to it, ask where it is needed and how much enamel will be removed.

Our Invisalign treatment page explains the clear aligner option before your consultation.

What are attachments and do they come off?

Attachments are small, tooth-colored composite bumps bonded to selected teeth. They give an aligner a surface to grip so it can apply the planned force. A guiding template helps position them accurately.

Attachments generally stay in place during treatment and are polished off when no longer needed. Do not try to remove one yourself. If an attachment comes loose, call the office to ask whether it needs replacing before your next appointment.

What does a day in the trays actually involve?

Most plans call for 20 to 22 hours of wear each day. Remove the trays for meals and for drinks other than water. You also take them out to clean your teeth, then put them back in promptly.

A long lunch followed by an afternoon coffee can use more tray-free time than you expect. Keep your case close enough that putting the aligners away becomes part of every meal:

• Put trays in their case, never in a napkin or on a lunch tray.
• Brush before putting them back in so food does not remain against your teeth.
• Drink only water while wearing the trays.
• Keep a spare case in your work bag.

Cleaning and soreness

Removable aligners let you brush and floss without working around fixed brackets. Clean the trays with lukewarm water and a soft brush; abrasive toothpaste can scratch them. Avoid hot water and hot car dashboards because heat can warp the plastic.

Pressure or soreness is common during the first day or two with a new tray and usually eases. Soft foods can make meals more comfortable. If you need over-the-counter pain relief, use it only if it is safe for you and follow the label. Call about persistent or worsening pain, or a cracked tray.

Holiday meals and travel

During holiday meals, keep track of how long your trays are out rather than leaving them aside for the whole gathering. Before traveling, pack the sets you will need and a spare case. Save the office number, and ask what to do if a tray is lost while you are away.

How often are trays changed and what happens at check-ins?

Aligners are commonly changed every one to two weeks, according to your prescribed schedule. Do not advance early because a tray feels loose, or skip a set to catch up. Each set prepares your teeth for the next movement.

Before changing trays, check that the current set seats properly. If it does not, call for instructions rather than moving ahead. Check-in intervals vary by case, so ask for your appointment schedule instead of assuming tray changes and office visits happen equally often.

When a tray stops fitting

A tray that will not seat needs attention before you continue through the sequence:

1. Check that you have the correct set and try seating it gently.
2. Stop if it will not fit without force.
3. Call the office and explain where the tray is lifting or feeling wrong.
4. Ask which tray to wear while you wait for further instructions.

How check-ins are scheduled

At a progress visit, the doctor checks whether your teeth are moving as planned and whether the aligners fit. Mention any difficulty meeting wear time so the advice reflects your actual routine.

Our office visits page provides appointment information, and the emergency care guide offers guidance for problems between visits. Confirm how soon a fit problem needs attention rather than waiting for a scheduled check-in.

What is a refinement and why might you need one?

A refinement is an additional set of aligners used to adjust tooth positions after the initial series. Teeth do not always follow the digital plan exactly. Needing more trays does not, by itself, mean treatment has failed.

Ask about refinements before agreeing to treatment: are they included in the quoted fee, and are there limits or additional charges? Get those terms in writing so you understand what the estimate covers.

Our Financial Information page is a starting point for payment questions. Your individual treatment estimate should explain the costs that apply to your plan.

What happens after the last tray?

Once active treatment is complete, retainers hold your teeth in their new positions while the supporting tissues adjust. Wear may begin full time and later change to nights, depending on your instructions. Ask for your schedule in writing, and do not reduce wear on your own.

Treatment length depends on the movements needed and how consistently the aligners are worn. An estimate made after an evaluation is more useful than a general average, and refinements can change the timeline.

Review our orthodontic retention information and retainer care instructions before your final visit. Ask what to do if your retainer becomes tight, damaged or lost.

Which office should coordinate your treatment?

Markowitz Orthodontics has offices in Blue Bell and Lower Merion. Consider the trip from work or school, not just from home, when choosing where to receive care. A manageable drive makes it easier to keep progress appointments.

Frequently asked questions

How long before you get your first Invisalign tray?

The digital scan itself takes only a few minutes, but receiving your first aligners involves separate planning and preparation. At the fitting visit, attachments may also need to be placed. Ask how much time to allow for that appointment and when your first trays are expected.

What is the most painful stage of Invisalign?

Pressure and soreness commonly occur during the first day or two after starting a new set, but there is no single stage that is most painful for everyone. Soft foods may help while your teeth feel tender. Persistent, severe or worsening pain should be assessed rather than assumed to be normal.

How can I tell what an Invisalign fee includes?

Ask for a written estimate that explains the planned treatment and whether refinements and retainers are included. Confirm any additional charges and payment terms before agreeing to care. A fee alone does not tell you what the full course covers.

How often will I need to visit the office?

Your doctor sets the check-in interval according to your treatment needs. Changing aligners at home every one to two weeks does not mean you need office visits that often. Ask for the expected visit schedule at your consultation, and call sooner if a tray stops fitting.

What is the hardest part of wearing Invisalign?

For many people, the challenge is fitting 20 to 22 hours of daily wear around meals and drinks. Keeping trays in a case helps prevent accidental loss, but you still need to put them back in promptly. If that schedule does not seem realistic, say so at the consultation so you can discuss a treatment option you can follow.
