Aligners can straighten your teeth without causing pain or mouth injuries. They're as effective as braces in fixing teeth that are mild or moderately crooked.
Aligners are clear, smooth, and almost invisible. They’re hard for people to see unless they look hard. But they’re also incredibly powerful.
For many people with crooked teeth, they’re just the right solution. You may have heard that this is a “compromise solution.” But this just isn’t true.
Key facts about aligners & teeth straightening
Aligners are most effective when worn at least 22 hours per day, and each set is worn for a week or two before you swap out for a new tray.
Aligner treatment plans can last just four months. People using fixed appliances like braces can spend almost 20 months in care, although timeframes can vary from patient to patient.
What are Clear Aligners?
Clear aligners straighten your teeth and improve your smile. Instead of using brackets and wires, this type of orthodontics uses virtually invisible plastic trays to gradually move your teeth into position.
By aligning crooked teeth, this treatment can fix several dental issues, including these:
Crossbites
Overbites
Open bite
Overjets
Crowding
In a 2017 study, researchers examined 16 people who were treated with aligners. They found that the devices offered highly predictable tooth movement. They said the predictability of movement with aligners was 73.6%.
Benefits of Aligners for Teeth Straightening
The benefits of choosing clear aligner orthodontics include the following:
Virtually invisible treatment, fixing crooked teeth with greater aesthetic appeal than braces
Greater comfort without wires or brackets that could irritate soft mouth tissue
Removable for brief periods when desired, such as during meals or social occasions
Shorter treatment periods at times (from 4 to 18 months, depending on your aligner brand and case complexity)
Digital treatment planning that is easier to incorporate into teledentistry for remote monitoring
Fewer in-person appointments during treatment
How Do Clear Aligners Work to Straighten Teeth?
How could clear, plastic trays wrapped around your teeth make your smile even brighter? It's not magic or mystery. It's a scientific process directed by a dental professional.
Your dental professional must know what your teeth look like now to plan your path forward. A dental examination makes this possible.
Most professionals use impressions to help. You bite down into a tray filled with polymer, and your doctor has a good look at where your teeth are in relation to one another and your jaw.
Computer modeling comes into play. Your doctor transforms your molds into a 3D visualization. You see what your teeth look like now, and you observe how each tray will provide a tiny nudge in the right direction.
This step is critical, as it provides a roadmap for your aligner therapy. You must approve it before anything else happens.
Aligners are high-tech medical devices, and during the past several years, they have undergone many advances. Aligners can be made of shape-memory polymers and are printed with 3D technology. In other words, they are made just for your mouth and should be both comfortable and durable.
Your doctor will use computer modeling to guide the printing of your trays. Each one will shift your tooth into a slightly different position.
Some companies give you all of your aligners at once, perfectly labeled so you know which one to use. Other treatment formats provide just a few at a time.
Your aligner journey begins. You will:
Wear your aligners. In some treatment models, you wear the trays during the day only. In others, you wear them at night.
Protect your aligners. Take out the trays to eat, drink, and clean your teeth. If you lose or break a tray, you'll order a new one and delay your treatment accordingly.
Swap trays. Every week or two, you'll change to a new aligner.
Keep in touch. Progress exams ensure that your teeth are moving on schedule.
Effectiveness of clear aligners for teeth straightening
Clear aligners are remarkably effective in moving your teeth. Trays wrap around the entire tooth, from root to tip, and apply gentle but consistent pressure. Your teeth respond by shifting position ever so slightly. With each tray, you move closer to the smile you always wanted.
Aligners work best for cases of mild-to-moderate crookedness. But if your teeth are too crooked or out of alignment, you might need a fixed orthodontic appliance. If you aren’t approved for aligner treatment, consult an orthodontist for the best path forward.
Some types of aligners are directed by doctors via telemedicine. Patients never have in-person appointments. In a 2020 study, researchers designed a 24-question survey to assess how satisfied people were with this type of treatment. They found that 87.5% of people were happy with their care.
Do clear aligners work as well as braces?
The main similarity between clear aligners and braces is that both can straighten your teeth by applying gentle continuous pressure. Patients must wear retainers after having their teeth straightened with either aligners or braces. But there are differences.
Braces and aligners differ in these ways:
Better oral health: Metal braces are permanently fixed in place, while aligners are removable. This means you can take your aligners out to brush your teeth or eat, making them more convenient and easier to keep clean than metal braces. Researchers say that oral health is better in people who use aligners as opposed to traditional braces.
Discipline: Since aligners are removable, it takes a little extra self-discipline to wear them as prescribed. Noncompliance with your treatment plan can limit its effectiveness. In a study of people using aligners, just 36% were fully compliant with their treatment plan and wore their aligners at least 22 hours per day. The others were not. Compliance is not a problem with braces, as they cannot be removed.
Supervision: Patients need multiple appointments for braces, which may pose a challenge for some patients. Many aligner formats are conducted via telemedicine, so you can comply while staying home. Researchers say aligners provide a comfortable treatment experience, and often, they require fewer emergency visits.
Appearance: While braces are constructed from brackets and wires, aligner trays are single pieces of molded plastic.
Timeframe: Treatment with braces can take years, while many aligner programs are finished in just a few months.
Comfort: Braces can scrape your dental tissues, while aligners are smooth and easy to wear.
Understand the limitations of aligners
While aligners are a safe and effective therapy for many people, they’re not right for everyone. In fact, some types of orthodontic problems aren’t ideal for aligner therapy.
The American Association of Orthodontists explains that aligners aren’t ideal for people with more severe dental problems. If your teeth are severely crooked or displaced, you may need treatment with braces instead.
Am I a candidate?
Clear aligner therapy can correct crooked teeth and bite problems. Generally, you’re a good candidate for the treatment if you meet these criteria:
You have mild to moderate orthodontic problems.
You’re willing to comply with treatment. You will need to wear your aligners per their instructions, often up to 22 hours per day.
Speak with an aligner treatment company for advice on whether this option is a good fit for your lifestyle needs and the desired results.
How can I pay for aligners?
According to surveys conducted by CostHelper, in-person treatment with aligners like Invisalign costs an average of $5,000. At-home versions can cost much less.
Aligners are considered orthodontic tools. Some types of dental insurance plans cover orthodontic care, but others limit coverage to people 18 and younger. If you plan to use your dental insurance to pay for treatment, you must read your insurance plan carefully before you get started.
Some aligner providers offer financing, so you can use private loans to pay for your care. Others will encourage you to apply for loans with companies like CareCredit.
If you have a health savings account (HSA), you could use these funds to help pay for aligners. An HSA is typically paired with a high-deductible health insurance plan and allows you to set money aside for qualified medical expenses. An aligner is an approved expense.
If finances are a concern for you and your smile, talk to your provider and explore your options. Together, you can find a plan that works for you.
