The 4 Cheapest Invisible Braces (Clear Aligners)

NewMouth is reader supported. We may earn a commission if you purchase something using one of our links. Advertising Disclosure.

Orthodontic treatments like Invisalign are an effective way to straighten your teeth. But they can be expensive and cost you $3,000 to $8,000.

Insurance also doesn’t cover these services unless you have orthodontic benefits. Unfortunately, these can also get pricey and cost you up to $200 a month.

At-home clear teeth aligners are affordable alternatives to traditional orthodontics. They can save you thousands of dollars and still help you achieve a straighter smile.

Many brands also offer flexible financing options like monthly payment plans. This lets you split the treatment cost across several months and fit it into your budget.

Other Clear Aligner Options 

Now that you know which clear aligners are the most affordable, here are your other options and why you should consider them:


Candid is great if you’re leaning more towards at-home teeth straightening but still want to receive professional dental care.

To get this treatment option, you must visit a local dentist or orthodontist who offers Candid and can assess you to see if you’re a good candidate.

They will design your treatment plan and continue monitoring your progress remotely once you wear your prescribed aligners.


We like Smileie because it lets you choose a treatment that suits your needs. You can straighten your top and bottom teeth or just one of them.

It also has some of the cheapest clear aligners. You can buy them upfront for $999 to $1,399 or pay $63.99 to $76.99 per month.

Smileie is a new brand, however. It launched in 2022 and isn’t as well-established as the other clear aligner companies.


SnapCorrect is known by customers for its “barely there” aligners that are discreet and comfortable to wear.

It’s also one of the more affordable aligners that can be covered by your flexible spending account (FSA), costing only $1,749 upfront.

However, you may end up spending more if you opt for a monthly payment since SnapCorrect doesn’t offer zero-interest installments.


2Usmiles gives you the cheapest way to get started with at-home teeth straightening, thanks to its affordable impression kits that cost $9.95.

It also has affordable pricing and costs $1,495 to $1,645 upfront or $104 to $118 monthly. Although it does require a hefty downpayment of $399. 

2Usmiles is still a new brand and doesn’t have many reviews. So we can’t blame you if you’d rather spend money on a more trustworthy company.


ClearCorrect is a more reliable and effective way to straighten teeth. It treats different types of misaligned teeth, including severe cases.

That’s because it isn’t an at-home option like Byte or SmileDirectClub. It’s an in-office aligner that requires dental professionals to oversee the treatment.

You’ll be asked to visit the clinic regularly. Your dentist or orthodontist can fit the aligners into your teeth, replace them, and adjust them as needed.

ClearCorrect typically costs $4,000 to $6,000. This makes it more expensive than at-home aligners but cheaper than Invisalign.


Invisalign remains to be the top in-office clear aligner for correcting mild to moderate teeth misalignment and severe bite problems.15,16

Like ClearCorrect, you’ll need to visit the dental office regularly so a qualified dentist or orthodontist can ensure your treatment is going as planned.

Invisalign clear aligners are less convenient than at-home brands. But they’re more comfortable and practical than traditional metal braces. 

Unfortunately, Invisalign is only a good option if your budget allows it. Its treatment costs are expensive and can range from $3,000 to $8,000.

If you only have mild to moderately crooked teeth, there are more affordable at-home clear aligners to choose from.

Why Trust Our Review?

To find the best cheap invisible braces on the market, we:

  • Spent 200+ hours researching the most trusted affordable brands
  • Scanned 500+ customer reviews for each clear aligner
  • Consulted 10+ health experts, including licensed orthodontists
  • Talked to 3 industry experts like CEOs of the top clear aligners
  • Reviewed over 20+ research papers on clear aligner kits
  • Asked 3 of our writers to test different teeth-straightening kits
  • Had our in-house dentists fact-check our article for accuracy
  • Updated our review every month with the latest information

We recommend at-home clear aligners if you have mild teeth misalignment. View our top recommendations.

Are Cheap Teeth Aligners Safe?

If you choose a trusted brand with mostly positive reviews, daytime aligners are generally safe to use.

They can help correct mild or moderate teeth misalignment, such as:

  • Overlapping and crooked teeth (dental crowding)
  • Too much spacing between teeth (gapped teeth)
  • Twisted or rotated teeth

However, we don’t recommend using night-only aligners because there is currently no evidence that they are safe or effective.

At-home invisible aligners are also not advised for severely misaligned teeth like an overbite, underbite, and open bite.

Do Clear Aligners Cause Side Effects?

When you wear clear aligners for the first time, you may feel sore and uncomfortable and experience changes in your speech.

For instance, you may suddenly find it difficult to pronounce “s” and “z” clearly (lisp) or hear whistling sounds when you talk.

These are normal side effects and usually disappear once you get used to wearing invisible aligners.

What to Consider When Getting Clear Aligners

Choosing the best clear aligner brand isn’t easy if you don’t know what to look for. Here are five things to consider to narrow it down:

1. Level of teeth misalignment

There are two kinds of clear aligners: in-office and at-home. What you’ll need depends on how severe your teeth misalignment or malocclusion is:

  • In-office clear aligners like Invisalign and ClearConnect work on mild, moderate, and severe misalignment. In-office visits to a dentist or orthodontist are required, but you can continue your treatment at home.
  • At-home clear aligners such as ALIGNERCO and Byte work on mild and moderate malocclusions. Treatments are done at home and are usually monitored remotely by a dental professional.

If you want to get your teeth straightened, it’s best that you talk to a dentist or orthodontist to find out which treatment option is for you.

2. Treatment costs and your budget

Many people just look at the price tag of clear aligners. But this only covers initial treatment costs. You should also consider other expenses, like:

  • The cost of the impression kit (if it isn’t included)
  • The cost of retainers needed after treatment
  • Other tools and products that will maintain your smile

If it takes longer to straighten your teeth or if your teeth shift back into place after the treatment, you may need more aligners to correct them.

While some companies have guarantees to help cover the cost of additional aligners, others don’t. You’ll have to pay for them yourself.

You must compare these costs across different brands to see which ones are within your budget.

3. Availability of flexible payments

If you can’t pay for the full treatment cost upfront, look for a brand that offers affordable monthly installments so you can fit it into your budget.

Companies that offer zero-interest or low-interest monthly installments and little to no downpayment will help you save more money in the long run.

4. HSA, FSA, and insurance

Most clear aligners are covered by a flexible spending account (FSA) or a health savings account (HSA).

Dental insurance policies also cover some brands or are in-network with major health insurance companies.

Find out which of these options are available to you and how much coverage you’re getting for your chosen aligners.

5. Treatment time

Clear aligners can straighten teeth in 3 to 18 months. Average treatment times help you gauge how long you must wait before seeing results.

Go for a brand that can give you results within an allowable time frame.

Remember that the actual time it takes to get straight teeth will depend on how crooked they are and if you wear clear aligners as prescribed.

The fewer misalignments you have, the faster the results.

Interested in straightening your teeth at home? Here are the best clear aligner companies.

Should I Get Braces or Affordable Teeth Aligners?

  • When to get traditional metal braces: If you have severely crooked teeth, bite issues, and other dental problems that cause jaw misalignment.
  • When to get at-home teeth aligners: If you have mild to moderately misaligned teeth and don’t have bite problems.
  • When to get in-office teeth aligners: If you have mild to severe teeth misalignment and want a more comprehensive treatment that’s still more affordable than traditional braces.

Which Clear Aligner is Right for You?

  • Choose Byte if you want the best value for your money. You’ll get everything you need to have that perfect smile: from teeth whiteners to a guarantee that offers new aligners if your treatment doesn’t work.
  • Choose ALIGNERCO if you want the most affordable aligners you can get upfront. But because its retainers cost $215, the upkeep for maintaining your straight teeth is going to be expensive.
  • Choose NewSmile if you want to split your payment into affordable monthly installments. There are plans with little to no downpayment, making it a budget-friendly option.
  • Choose SmileDirectClub if you have an insurance policy with one of its in-network providers. SDC is partnered with over 13+ insurers, including Aetna, Anthem BlueCross, Delta Dental, and United Healthcare.

The Takeaway

At-home clear aligners are a practical and inexpensive way to straighten your teeth. When picking a brand, you must consider:

  • How severe your teeth misalignment is
  • The total treatment cost and your budget
  • Availability of flexible payments
  • If your HSA, FSA, or insurance will cover it
  • The time it will take to complete treatment

Remember to discuss your teeth straightening options with a dental expert. They can help you choose an orthodontic treatment based on these factors.

NewMouth Rating System

We ordered the best kits that met our criteria and had in-house writers test them out throughout the duration of their prescribed treatment.

While testing the clear aligners, our team assessed and scored them based on five traits. Each trait was assigned a “weight” so we could calculate their individual rating and weighted average scores on a scale of five.

Here is how we rated the best clear aligners on our list:

Customer Experience
Pricing and Financing
Customer Service and After-Sales Support
Brand Reputation

Customer Experience

Using artificial intelligence, we gathered and analyzed feedback from hundreds of people who tried our list's clear aligners.

This helped us determine the users’ experiences with a brand, including:

  • Its availability for in-person and/or virtual consultations
  • The accessibility of its clear aligners and ease of ordering
  • Whether it gives clear instructions for taking dental impressions 
  • The fit and comfort of its invisible braces when worn


We compared the brands’ average treatment times and effectiveness for correcting mild and moderate teeth misalignment.

  • Access to dental experts who can answer your questions and guide you throughout your treatment
  • A dedicated app that reminds users to switch aligners and allows them to conveniently track their progress and contact support
  • Regular virtual and/or in-person check-ins with a dental professional who can ensure that your treatment is going well
  • Additional dental treatments such as teeth whitening

Pricing and Financing

We explored the total treatment cost of invisible braces, including their upfront prices, flexibility of payment options, eligibility for insurance, and maintenance costs for additional retainers.

Customer Service and After-Sales Support

Our team performed an in-depth investigation of each brand’s customer support when answering queries and resolving issues. We assessed their:

  • Availability
  • Responsiveness
  • Knowledge
  • Reliability
  • Friendliness

We also checked companies to see if they offered guarantees for clear aligner adjustments, refinements, replacements, or refunds if you’re not qualified or if the treatment doesn’t work for you.
