Teeth Straightening Kit

Clear Aligners Overview

Clear aligners are an excellent way to straighten your teeth if you are looking for a convenient option. They are a discreet and removable alternative to metal braces.

The trays are made of BPA-free plastic and are virtually invisible when in your mouth. 

There are two types of clear aligners available, including at-home aligners and in-office aligners.

In-office aligners, such as Invisalign and Clear Correct, require you to visit an orthodontist or dentist for check-ups. 

At-home aligners, also called mail-in aligners or direct-to-consumer aligners, do not require in-office visits with an orthodontist. These aligners are more convenient than in-office options. 

Popular at-home aligner brands include:

• Candid (best overall)
• NewSmile
• byte®
• SmileDirectClub
• ALIGNERCO

What Are Teeth Straightening Kits & How Do They Work?

The first step of at-home aligner treatment is to take a candidacy quiz online.

If you're a candidate, the next step is to order a teeth straightening kit. These kits are delivered straight to your door, eliminating the need to visit an orthodontist for an in-person scan.

Once you receive the kit, you'll take impressions of your teeth and send them back.

From there, an orthodontist will make a digital 3D model of your teeth. This interactive model shows your teeth straightening progress from start to finish.

If you approve the plan, a dental technician will create the aligners based on the 3D model. This is what the model will look like:

All of the aligners will be sent to your home address at once. You’ll change the trays out every 1 to 2 weeks. The aligners should be worn for 20 to 22 hours a day.

The number of aligners you need depends on how misaligned your teeth are and the length of treatment.

Some brands like Candid also require remote check-ins every two weeks (via an app) to ensure your teeth are moving correctly.

Differences Between Braces & At-Home Clear Aligners

Traditional braces and clear aligners are both effective ways to straighten your teeth.

Here are the main differences:

1. Aligners are removable and convenient. This means you can eat, drink, brush, and floss more naturally. Although convenient, if removing the aligner trays for eating or drinking anything apart from water seems inconvenient, this treatment may not be for you.
2. At-home aligners can only treat minor to moderate teeth misalignment cases. Severe cases typically require braces and possibly other orthodontic devices like headgear (for children).
3. The success of aligners depends almost entirely on the wearer. If you do not wear your aligners for the right amount of time each day, they will not work correctly. Braces eliminate this risk because they are not removable.

Teens and older adults with minor to moderate misalignment are typically the best candidates for aligners. If you're younger than 12 and have severely misaligned teeth, talk with your orthodontist about braces.

How Do I Know if I am Eligible for Online Teeth Aligners?

Not everyone is a candidate for at-home clear aligners because they can only fix:

• Minorly to moderately crowded teeth — when some or all of your teeth overlap
• Gapped teeth — one gap or multiple gaps between the teeth
• Other minor to moderate spacing or bite issues

There are four reasons for ineligibility, including:

• Your teeth are severely misaligned
• You have untreated jaw discrepancies that require in-office orthodontic treatment (e.g., braces)
• You have gum disease or untreated cavities
• You have a permanent retainer (must be removed before treatment)
• You have existing dental restorations such as implants, bridges, or partial dentures

Braces can fix more complex cases of teeth and jaw misalignment.

Pros and Cons of At-Home Teeth Straightening 

As with any product, at-home aligners have advantages and disadvantages:

Pros of at-home aligners

• They are more affordable than traditional braces, lingual braces, Invisalign, and Clear Correct. Invisalign can cost up to $8,000, while at-home aligners cost up to $2,300 (average is under $2,000). 
• No in-office visits are necessary before, during, or after treatment. Check-ups are completed remotely. Some brands like Candid require bi-weekly, remote scans with a licensed orthodontist.
• Treatment is typically faster than braces or Invisalign; between 6 and 12 months (only minor to moderate cases).
• The aligners are discreet and removable. You don’t have to worry about having visible metal brackets and wires on your teeth throughout treatment.
• Payment plans are available for those who don’t want to pay for the total cost upfront. 

Cons of at-home aligners

• They only offer remote monitoring, so treatment is less predictable without in-office visits. However, when monitored by an experienced orthodontist, remote invisible aligner treatment is effective and safe.
• Most at-home aligners can only treat minor to moderate cases, including slightly crowded/crooked teeth and gapped teeth. Overbites, underbites, open bites, and similar forms of malocclusion require more invasive orthodontic treatment.
• Most at-home aligners do not require x-rays before the treatment plan is created. It is essential to visit your dentist to check for cavities and other problematic oral conditions before beginning treatment. Candid is an affordable brand of at-home aligners that offers x-rays and in-depth scans at Candid Studios. Find one near you.
• At-home aligners are not endorsed by the American Association of Orthodontists (AAO) because of the risks of tooth and root damage without the direct supervision of a dentist.

At-Home Aligners: Brand Safety Comparison

Why Trust Us? How We Choose Brands

All clear aligner products on this site are heavily researched, vetted, and reviewed before recommending them to readers. These are our standards for determining a reputable clear aligner brand:

1. We figure out if the brand works with dentists or orthodontists. If they don’t work with licensed professionals in the industry, we do not recommend their products. This ensures customers receive the highest quality care and their treatment is overseen by a licensed professional from start to finish. 
2. We talk with company leaders to ensure the product is safe and effective. This may include asking for safety documentation and asking leaders about their manufacturing process. 
3. We compare reviews from multiple sites. Our writers are instructed to read reviews and compare pros and cons. We clearly list the advantages and disadvantages of each clear aligner product to keep the content transparent. 
4. We look into pricing and features. This ensures customers are getting the best quality products at reasonable prices.
5. We check to make sure the customer service is high quality. We only recommend aligner brands that have clear instructions on how to contact them. Brands that offer “lifetime guarantees” are also well-respected. 

All clear aligner product pages are medically reviewed by a licensed dentist or orthodontist.

Our dentists are instructed to flag any recommendations they don’t agree with. Any products that don’t meet their high standards are removed.

Candid: Best Overall (Editor's Pick)

NewSmile: Budget Aligner

NewSmile is one of the most affordable at-home aligners, but they are also one of the newest companies.

Unlike most at-home aligner brands, NewSmile aligners do not touch your gums. They are trimmed to comfortably sit along your gum line in a ‘scalloped fashion.’

Not only does this design cause less irritation, but it also makes the trays less visible. 

Once you receive the impression kit, you should get an email to book a time with an Impression Specialist. During this video call, they will walk you through the process to ensure accuracy.

NewSmile’s Fast Track Aligners are worn for 22+ hours a day. They should only be removed for cleaning, eating, and brushing. Treatment takes between 4 and 6 months, but sometimes up to a year. They cost $1,195.

NewSmile’s Night Aligners require less daily wear time (10+ hours a day). They cost $1,295.

* NewMouth does not recommend night aligners because there is no scientific proof that they are safe or effective. Learn more here.
