There are three main categories of braces:
Traditional metal braces are a system of brackets attached to each tooth. The brackets connect to each other with wire, which, when tightened, causes the teeth to move in the correct direction. Metal braces must be installed and maintained at an orthodontist’s office. Usually, patients visit the office once every four to eight weeks to have their wires tightened.
These work in the same way as traditional braces but are made out of a clear ceramic to match the color of your teeth. Like metal braces, treatment with clear braces require regular visits to an orthodontist’s office.
Clear aligners, also known as invisible braces, are a series of clear plastic trays that resemble mouth guards. They are worn on the top and bottom teeth to gradually move them into the correct position. Though they are not truly invisible, it is often difficult to tell when someone is wearing them.
There are several things to keep in mind when deciding whether to opt for traditional braces (made of clear or metallic materials) or aligners:
The process of teeth straightening with clear teeth aligners is relatively quick - on average about four to six months. To begin, you'll need to decide whether you want to opt for a fully remote service, or a company that uses some combination of virtual and office-based care. There are a variety of companies that use a 100% remote version, and several that require visits to a local office. Most websites offer a screening process to see if you might be a candidate for their product before you decide to buy an entire service or an impression kit.
Most of the companies we have reviewed offer an at-home impression kit to get you started with treatment. Some companies—Like AlignerCo—only offer this option. Impression kits are included with the price of treatment or sold separately if you don’t want to commit to the whole teeth straightening kit from the start.
The impression kit includes a tray and a putty-like substance to fill it with. You will gently bite down on the tray. The putty hardens after removal from your mouth. You’ll then send the mold to the aligner company so they can make your aligners. Most companies offer clear directions, online videos, and customer support to walk you through the impression process.
Several companies also offer the option to visit an office to get a 3D scan of your teeth, instead of a putty impression. SmileDirectClub and Strayt offer both options, while Candid only offers the in-person option. With a 3D scan, the orthodontist takes a picture using a special software system that maps the position of your teeth.
Whether you opt for at-home impressions or office scans, you'll need to wait for several weeks to receive your custom made series of teeth aligners. You’ll wear each pair of aligners for a specific amount of time, usually two or so.
With most companies, you have the option of choosing a wearing schedule: 20-22 hours per day for a quicker treatment time, or 8-10 hours per night with a longer treatment time. As you progress through your series of aligners, your teeth will move closer to their ideal positions.
After your treatment is finished and you're pleased with your results, you'll need to wear a retainer at night afterward, so your teeth don't move back to their original positions. Several companies include a first set of retainers in their treatment package. You’ll need to keep up with your retainers, and replace them every six months or so, to keep your teeth in line and maintain any money-back guarantees from the company.
| Invisible Braces | Price | Average Treatment Time |
|---|---|---|
SmileDirectClub | $1950 | 4-6 months |
Candid | $3-5000 | 6 months |
AlignerCo | $895 | 4-6 months |
NewSmile | $1395 | 4-6 months |
Strayt | $1495 | 4-8 months |
Aligners are used in a number of situations, and a professional orthodontist will be equipped to assess your situation to determine if you are a good candidate for this type of procedure. Some of the more commonly experienced dental problems that teeth aligners are used to correct include:
For more complex cases and severe dental irregularities, you’ll need to opt for traditional braces.
Most of the companies we’ve reviewed offer quizzes online to see if you are a good fit for their product. You can also contact the company through their website or call them to discuss your needs and concerns.
In some cases, the aligner company’s in-house doctors will review your impressions or 3D scan and discover that you are not a good candidate for correction with their product. In most of these cases, you’ll be able to receive a refund for anything you’ve paid so far.
The duration of treatment with any orthodontic solution varies greatly according to the needs of each patient. In general, you can get faster results with aligners than with traditional braces:
With invisible aligners, it’s important to follow the manufacturer’s instructions exactly. Not wearing them as directed means longer treatment times.
It’s important to maintain your aligners properly so they don’t degrade or cause bad breath or other problems. Each company provides instructions on how to maintain their aligners. Usually this involves soaking briefly in a cleaning substance--like vinegar, soap, or baking soda--and rinsing completely. Several companies sell special devices to clean and disinfect your aligners.


Candid was originally launched as an at-home aligner system, like SmileDirectClub. However, they have switched to an office-based system, where you begin with a local office and check in with them virtually. Each office sets their own price and insurance coverage terms.
On the Candid website, you can take a quiz to see if you may be a candidate for their aligners and find a local office. The office will coordinate your scans and design your treatment. You’ll receive your aligners in the mail, along with a scanning tool to share your progress with your doctor virtually. Treatment times average six months, and you’ll need to wear a retainer to maintain your results.


AlignerCo aligners are made from ultra-clear BPA-free biodegradable plastic. Their treatment system is the lowest-priced option on the market, starting at $795 if paid upfront. Their business model is a completely remote one, so you’ll take an impression at home and mail it to them.
Their orthodontists will review your impression and—if they determine that their product will work for you—they will design a set of teeth aligners to be delivered to you. You can choose a 20-22 hour wearing schedule (with results in 4-6 months), or nighttime aligners for 8-10 hours per night (with results in 6-8 months).


NewSmile offers a competitive option for at-home invisible aligners. Their aligners are cut below the gums, so you don’t feel any discomfort from the plastic touching your gums. To get started, you’ll need to order their package, which includes their at-home impressions kit, your treatment preview, a set of teeth aligners, retainers, and tooth whitening gel. As with other companies, you can choose an all-day or a longer nighttime-only wearing plan.
NewSmile does not accept insurance as a form of payment, but you may be able to apply to your dental insurance company for reimbursement, depending on your plan. You can also pay using FSA/HSA accounts.
