Order a kit

byte is famous for its short treatment time. It averages to about 3 months thanks to its proprietary HyperByte technology. That is a device that comes with the kit.

The HyperByte helps shift teeth into alignment by emitting high-frequency vibrations while also reducing discomfort. Orthodontists offer their patients similar devices, but they can cost up to $900. This is almost as much as the entire byte cost.

byte gives you both regular and nighttime-only options. The whole process is remote. After the treatment, you will have to wear retainers. The first set is free.

Candid Co

Book a visit

Candid’s biggest merit is the amount of effort they put into giving patients the best possible quality of treatment. All plans are designed by orthodontists. Afterward, that same specialist provides remote monitoring.

This happens via a device included in Candid’s kit. All changes are tracked so the orthodontist can react accordingly to how the process pans out. He or she might give you the go-ahead to move onto the next aligners or stay with one set for longer, if the teeth aren’t moving as expected.

The Candid treatment can be fully remote with an impression kit and photos. Alternatively, you can get started by visiting a Candid Studio for a free scan. The whole process lasts 6 months on average.


Book a visit

SDC is the most established home teeth straightening kit on the market. They offer two modes of treatment: full or nighttime. The first is, of course, a lot faster. The average duration is 6 months.

In terms of specialist support, SmileDirectClub offers a check-up with a licensed dentist or orthodontist every 90 days. The full treatment can be done remotely if you make your own teeth impressions, but there are also SmileShops if you prefer to have a scan initially. SDC will soon be available in-office much like Invisalign.

Aligner Co

Order a kit

Aligner Co offers the cheapest invisible braces treatment on the US market. The price includes an impression kit, your custom aligners, and the first set of retainers.

Aligner Co is also famous for its customer service. It is reportedly easy to get in touch with and always ready to help. You take your own impressions at home with the assistance of their instructional video. There is also a live chat to help you out if you have any queries.

The aligners themselves are designed by orthodontists. They will arrive about three weeks after you accept the treatment plan. Many patients claim that they can see clear results after 5 months.


Order a kit

The greatest thing about SnapCorrect is that their aligners are the clearest out there. You don’t have to worry about them being cloudy or matte. The trays are completely transparent, so no one will know you are undertaking treatment.

The process takes from 3 up to 18 months. After that, you wear a retainer, the first set of which comes included in the price. Everything happens from home since the journey is completely remote.

If you run into any trouble you can call, chat, or email SnapCorrect customer service 5 days a week.


Find a doctor

Invisalign is probably the most well-known invisible braces brand offered in dental offices. This means you have to take into account regular visits. On the Invisalign website, you can choose a dentist or orthodontist in your area who will monitor your treatment.

You get aligners set by set during each appointment. There are usually about 25 trays in total. They move teeth by a fraction of a millimeter to ensure treatment is safe and all organs in your mouth are cooperating. You may also need composite attachments for your teeth to boost the effectiveness.

Patients usually wear every set for two weeks. Your doctor will decide whether you are suitable for changing aligners every week. This means your treatment can last as little as 3 months.

Invisalign treatment can often be effective on complicated cases due to direct interaction with the orthodontist. There are also other in-office brands and some orthodontists offer their own, custom trays.

Who is a candidate for clear aligners?

Clear aligners are generally meant for those whose misalignment is not severe. If you have slightly crooked, spaced, or crowded teeth, such a treatment could be great for you.

Dr. Henry Hackney

Remote orthodontic treatment is only recommended for patients that require minimal changes. It is also extremely dependent on patient compliance due to minimal interactions with orthodontist in person.

Since there are no radiographs taken with remote treatment, it is unsuitable for those whose orthodontic or general dental issues are complex.

The important thing to remember is to visit your dentist regularly throughout the treatment. Invisalign offers regular check-ups, but those don’t include maintenance such as a teeth cleaning.

Most brands also require the patient to have all permanent teeth, no baby dentition. This means you must be about twelve years old or older. It’s also worth reaching out to the provider if you have crowns, bridges, or dental implants. For some, this could make treatment impossible.


  • Slight misalignment
  • All permanent teeth
  • General oral health
  • Consistency

Not so good

  • Severe misalignment
  • Bite issues
  • Crowns, bridges, and implants
  • Gum disease
  • Active tooth decay
  • Baby teeth

Some of the issues above can be fixed prior to treatment, so if you are rejected make sure to target the problem. You can reapply and perhaps be accepted the second time.

How do invisible braces work?

Clear aligners work on a similar basis to traditional wire brackets. They apply force to the dentition that is not placed optimally to very slowly move it. Each tray is slightly more symmetrical and therefore arches steadily become even.

Patients should wear invisible braces as much as possible, at least 22 hours a day. It’s easy to spot that you should also be sleeping in them.

The aligners should really only be taken out in two situations. The first is eating and drinking and the second is for cleaning. You should also brush your teeth every time, so they help in forming healthy habits.

How much are invisible braces?

The price range for invisible braces is very wide. It all depends on the brand, though. The biggest price indicator seems to be how much time a specialist has to devote to the patient.

That’s why in-office options tend to be the most expensive. The average Invisalign cost is $5,700. The price is also dependent on the type and severity of misalignment you have. Other factors include the experience of the specialist and your location.

Home teeth straightening kits usually have a set figure which doesn’t change from patient to patient. The costs range from $1,395 to $2,400 (excluding impression kits).

Below we have prepared a quick run-down of invisible braces costs.

Aligner Co$75$1,395
Invisalign-$5,700 on average

In comparison to prices of metal or ceramic braces, invisible aligners, especially at-home kits, are clearly a lot more affordable.

The cost of treatment is a very important factor in choosing a brand to go with. Don’t forget, however, to consider what the package consists of and what the customer reviews are like.

Watch out for scams. A great example is Smilelove, who, during the COVID-19 pandemic, completely neglected to ship out deliveries. Customers are still struggling to get their money back.


What do invisible braces look like?

Invisible braces are clear, plastic trays that go on your teeth. They are removable. Each next pair has a slightly straighter design to shift your teeth into place.

If you go with Invisalign, you are likely to have buttons and attachments on the trays that will further help in alignment.

Are invisible braces effective?

All of the invisible aligner companies described in this article are backed up by thousands of reviews. If your alignment issue is mild, you are likely to be very satisfied with the results.

Is straightening teeth at home safe?

Home teeth straightening kits are designed by dentists and orthodontists to make sure the treatment is safe and effective. There are risks to aligning your teeth at home as with any other procedure, but patient reviews are overwhelmingly positive.

If your misalignment is too complex or severe, you will be rejected for remote treatment. Instead, you might have to go with Invisalign or traditional braces.

How long does it take for invisible braces to work?

Most treatment plans last a few months. Invisalign can quote longer times, but this is because they take on more complicated cases and make use of buttons and attachments.

Byte claims to offer the shortest average treatment plan at 3 months.

Do invisible braces hurt?

When you are aligning your teeth with invisible braces, you are shifting their position by force. The trays put constant pressure on the dentition to force them into alignment. This causes soreness in your jaw and gums.

Devices like the HyperByte or chewies that are often included in straightening kits can help alleviate pain, but you are sure to experience some degree of discomfort either way.

In order to avoid unnecessary pain, adhere to instructions strictly. If you don’t wear your trays enough, if you lose them, or if you move on to the next set too quickly, the treatment is likely to be more painful.
