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 your 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 types of aligners are more convenient than in-office aligners.

What Are Teeth Straightening Kits & How Do They Work?

The first step of at-home aligner treatment is to take a candidacy quiz online. Then, if you are a candidate, you’ll order a teeth straightening kit. These kits are delivered straight to your door, eliminating the need to visit an orthodontist for an in-person teeth scan.

Once you receive the kit in the mail, you will take impressions of your teeth and send them back. From there, a dental technician will create the aligners based on the impressions you sent. They will also send you a treatment preview of how your teeth will look from start to finish. 

After the treatment plan is approved, the aligners will be sent to your home address. You’ll change the trays out every 1 to 2 weeks and wear each new set of aligners for 22 hours every day. The number of aligners you receive depends on how crooked your teeth are and the length of treatment. Virtual appointments with a doctor or orthodontist will also be required to ensure your teeth are moving correctly throughout the treatment process. 

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 mild teeth misalignment cases, such as:

  • Crowded Teeth — when some or all of your teeth overlap.
  • Gapped Teeth — one gap or multiple gaps between the teeth.
  • Other minor 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.

Only Invisalign and braces can fix more complex cases of teeth misalignment.

Pros and Cons of At-Home Teeth Straightening 

Pros of at-home aligners

  • They are cheaper than traditional braces, lingual braces, Invisalign, and Clear Correct. Invisalign can cost up to $8000, while at-home aligners cost up to $2500. 
  • No in-office visits are necessary before, during, or after treatment. All check-ups are completed remotely with a licensed orthodontist or dentist. 
  • Treatment is significantly faster than braces or Invisalign, typically between three and six months (only minor cases can be treated, though).
  • The aligners are discreet and removable. You don’t have to worry about having visible metal brackets and wires on your teeth throughout treatment.
  • Some brands also offer nighttime clear aligners (that you only wear while sleeping), making them even more discreet and convenient. 
  • 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 there is a slightly higher risk of complications because treatment is less predictable without in-office visits. However, when monitored by an experienced orthodontist, remote invisible aligner treatment is effective and safe.
  • At-home aligners can only treat minor misalignment cases, including slightly crowded/crooked teeth and gapped teeth. Overbites, underbites, open bites, and similar forms of malocclusion require more invasive orthodontic treatment.
  • You will not get x-rays taken of your teeth before the treatment plan is created. It is essential to visit your dentist to ensure you don’t have any cavities or other problematic oral health conditions before beginning clear aligner treatment. 
  • At-home aligners are not supported or endorsed by the American Association of Orthodontists (AAO) because of the risks of tooth and root damage without the direct supervision of a dentist.

How Do I Get Started With At-Home Aligners?

Before ordering a teeth straightening kit, you can take a free candidacy quiz on candidco.com, byteme.com, or smiledirectclub.com to ensure eligibility. If you order the impression kit and are deemed ineligible for treatment, you will get a full refund for the kit.

ALIGNERCO offers the cheapest invisible aligners on the market.

Treatment costs $1,145 (or $99 for 11 months with the payment plan). Other clear aligner competitors are more expensive ($1,800 to $2,400).


While more affordable, they are also a newer company with fewer reviews than byte and Candid. They also do not work directly with orthodontists and dentists, which can affect the quality of care.

To begin the teeth straightening process, the first step is to order an impression kit online. These kits are just $39.99. After you receive the kit, you'll take a dental impression at home and send them back to ALIGNERCO.

They will create a customized treatment plan and send the aligner trays straight to your door.

ALIGNERCO also sells NightOnly Clear Aligners. They include the same benefits as regular aligners but require less daily wear time. Wear time is 8 to 10 hours a day and the treatment duration is 8 to 12 months.

Why You Should Trust Us 

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

Teeth Straightening Kit — FAQs

Does an orthodontist oversee home teeth straightening treatment?

Candid and Byte only work with qualified and licensed orthodontists, so your clear aligner treatment will be overseen exclusively by these professionals. SmileDirectClub and other brands do not work solely with orthodontists; they also work with dentists and doctors. 

How often do I need to wear home teeth aligners? 

At-home teeth aligners must be worn for at least 22 hours a day. Night aligners only need to be worn for about 10 hours a day. Byte and SmileDirect offer night aligners. Candid only offers traditional aligners. 

How long does home aligner treatment take? 

Home aligner treatment takes about six months (on average). Byte aligners move your teeth the fastest (treatment takes 3 to 6 months). If you don’t wear your aligners as directed, treatment can take longer.

What happens after home aligner treatment is complete? 

After treatment is complete, you’ll order a custom-made retainer to keep your teeth straight. Byte provides a free retainer with every purchase. SmileDirect and Candid retainers cost an additional $100. Retainers are to be worn for a lifetime. Each company gives instructions on how long to initially wear your retainers so your teeth don’t shift back.

Are financing/payment plans available?

Most clear aligner companies offer payment plans and financing options. You’ll pay a couple of hundred dollars up-front and then make monthly payments for about two years. 

Some aligners are partially covered by insurance. You can also use an HSA/FSA to pay for treatment. Check directly with the clear aligner company of your choice to determine the best financing option for your needs.
