Clear Aligner Treatment

Do I Need Aligners?

Clear aligners gradually move teeth using a series of removable trays. If you want straighter teeth, these are reasons to ask about treatment:

1. You have spaces or gaps between teeth
2. Your teeth overlap or look crowded
3. Your upper and lower teeth don’t meet the way they should when you bite down

Pain when you clench does not establish that you need aligners. Ask your dentist about the cause, including bruxism (grinding or clenching). A night guard helps protect teeth from grinding damage, but it does not straighten teeth¹.

Clear aligners aren’t right for everyone. A dentist or orthodontist needs to assess your teeth, gums, and bite before recommending treatment^2,3.

If you have severe teeth misalignment and bite issues (malocclusions), you may need in-office orthodontic treatments like traditional metal braces to get straight teeth.

Use this guide to understand treatment and care options. For shopping questions, compare clear aligner brands or visit the cost section below.

What Are Aligners?

Clear aligners are dental trays that help you achieve a straighter smile by gradually shifting crooked teeth (malocclusions) into alignment.

Unlike braces that use metal brackets and wires, aligners are clear plastic. They’re barely visible when worn, allowing you to straighten your teeth discreetly.

Aligners are also removable alternatives to braces. While braces remain attached to your teeth during treatment, you can remove clear aligners when eating, flossing, or brushing your teeth.

Other names for clear aligners include invisible aligners, teeth aligners, teeth straighteners, and teeth straightening kits. They’re not the same as clear braces or invisible braces.

What Are Clear Aligners For?

Clear aligners are used to treat several types of misalignment, depending on the individual case³:

• Crowded teeth: overlapping teeth
• Overbite: upper front teeth overlap the lower front teeth
• Underbite: lower front teeth overlap the upper front teeth
• Open bite: front and lower teeth that don’t touch with a clenched mouth
• Diastema: small or large gaps between teeth

The type of bite problem alone does not tell you whether aligners will work. Its severity and the tooth movements needed also matter². Do not assume a remote-care product treats every condition listed here.

How Do Aligners Work?

Clear aligner treatment includes a series of plastic dental trays that are custom-fitted to your teeth. Each aligner is designed to slowly move teeth, about a fraction of a millimeter at a time³.

Generally, you need to wear each tray for one to two weeks before switching to the next aligner. The number of invisible teeth aligners may vary depending on your treatment plan.

Mild discomfort is common when you first adjust to aligners³. Contact your treating clinician about persistent or worsening pain, a poor fit, or concerns about your bite rather than adjusting treatment yourself.

In-Office vs. At-Home Clear Aligners

The main difference is how you receive assessment and follow-up care. In-office providers also have you wear aligners at home; some combine office visits with remote monitoring³.

Before ordering, read our guide to at-home aligner safety and screening. It covers the assessment and supervision questions to ask⁴.

If you’re considering remote aligner care, arrange a dental assessment before choosing a provider. Our SmileSet aligner review explains the service, its limitations, and what to check before paying. An online quiz does not establish that treatment is suitable for you.

What Are In-Office Clear Aligners?

In-office care starts with a dental provider who assesses your suitability and manages treatment. Options include Invisalign and ClearCorrect.

Pros of In-Office Aligners

• You meet the clinician assessing your teeth and bite.
• Office visits allow your provider to check progress and discuss problems in person.
• Your clinician can recommend a different approach when aligners are not the best fit³.

Cons of In-Office Aligners

• Appointments require travel and time in your schedule.
• Prices and included services vary. Get an itemized quote, including retainers and any extra treatment trays.
• Provider availability depends on your location. Compare the care offered as well as the Invisalign cost.

What Are At-Home Clear Aligners?

At-home aligner services arrange much of the process remotely, using impressions or scans and online communication. Before paying, confirm who assesses your dental health and supervises treatment⁴.

Our guide lets you compare at-home aligner providers without repeating their full shopping details here.

Pros of At-Home Aligners

• Remote check-ins reduce travel for those parts of your care.
• Online plan information helps you compare services before contacting a provider.
• If you’re researching alternatives to Invisalign, compare the full cost alongside the assessment and follow-up offered.

Cons of At-Home Aligners

• A scan or impression alone does not replace an examination and appropriate diagnostic records⁴.
• Arrangements for in-person care vary. Establish where to get help if your teeth, gums, or bite need attention.
• A convenient wear schedule does not establish that a product suits your case. Read about nighttime aligner evidence and limitations before considering reduced wear.

How Much Do Aligners Cost?

Your total cost depends on the treatment plan and what’s included. You’ll find current brand-by-brand aligner prices in our cost guide, so this page sticks to the factors that change the number.

The cost of clear aligners depends on several factors, including:

• Your brand of clear aligners
• Your chosen payment option
• Your level of teeth misalignment
• How long your treatment lasts
• If you need extra dental work
• Your dental insurance coverage
• If you have HSA or FSA benefits
• Cost of dental checkups

Ask whether the quote includes the impression kit or scan, retainers, and refinements (extra treatment trays). After treatment, budget for retention and replacement retainers as needed⁶.

For financing, compare the total repayment amount, including interest and fees, with the upfront price. A lower monthly payment does not necessarily mean a lower total cost.

If budget is your priority, compare the cheapest clear aligners after checking which care options fit your needs.

Are Clear Aligners Covered By Insurance?

Clear aligners may be covered by insurance if your plan includes orthodontic benefits³. How much you get back depends on your insurer, the brand of aligners, and your dental provider.

To confirm your insurance coverage for clear aligners, you’ll need to:

• Ask your health insurance company
• Check with a clear aligner brand
• Talk to your dentist or orthodontist

Ask whether the provider bills your insurer or whether you must pay first and submit a claim. Confirm your expected out-of-pocket amount before committing.

Consider getting dental insurance that covers orthodontic devices like clear aligners. Here’s our guide on the best dental insurance plans.

Can I Use HSA/FSA To Pay For My Aligners?

Qualifying orthodontic expenses are generally eligible for flexible spending account (FSA) or health savings account (HSA) funds. The IRS includes orthodontic treatment in eligible dental expenses⁵.

Confirm eligibility and required documentation with your plan administrator. A provider accepting an HSA or FSA card does not guarantee that your expense qualifies.

How to Start Your Aligner Treatment

Treatment starts with an assessment, not a purchase. Use these steps to discuss your options with a dentist or orthodontist:

1. Get assessed: Have your teeth, gums, and bite examined. Your clinician decides which records, such as dental X-rays, scans, or impressions, are needed⁴.
2. Review the plan: Discuss the proposed tooth movements, alternatives, expected timeline, full cost, and who will supervise treatment. An online questionnaire is only a starting point.
3. Follow prescribed wear and monitoring: Ask how long to wear each tray, when to change it, and when progress will be checked. Contact your clinician if problems arise instead of changing the schedule yourself³.
4. Plan retention: Before finishing, confirm your retainer, its wear schedule, and how to get help with fit or replacement⁶.

Post-Treatment Retainers

Once you complete treatment, you need to wear retainers that are customized to fit your newly straightened teeth. This prevents teeth from shifting back so you can maintain a great smile.

Your orthodontist or aligner company sets the wear schedule, and some retainer use usually continues for life⁶. Replace a retainer when it cracks, warps, or no longer fits rather than on a fixed calendar. You also have to keep retainers clean.

For stable teeth after treatment, compare online replacement retainers. If your bite has changed or your old retainer no longer fits, see your dentist or orthodontist before ordering. Retainers hold teeth in position; they are not a substitute for treatment to move shifted teeth⁶.

Which Clear Aligner Do I Choose?

Choose a care model with your dentist or orthodontist before comparing providers. Discuss these practical questions:

• Suitability: Does the proposed treatment address your teeth and bite?
• Supervision: Who reviews progress, and how do you get in-person help?
• Wear schedule: Are you able to follow the schedule your clinician prescribes?
• Total cost: What do assessment, treatment, refinements, and retention include?
• Timeline: What happens if treatment takes longer than expected?
