Safest Teeth Whiteners
The safest ways to whiten your teeth explained
Invisalign treatment can take between 3 to 18 months. Treatment time varies widely due to several factors, including:
Here are 7 reasons why Invisalign treatment times vary:
Invisalign moves your teeth between (assuming it's worn most of the day, every day). This resolves most cases of gapped teeth in 3 to 6 months.
However, larger gaps (around 6mm) will take more time (up to 24 months in some cases).
A mild case of crowding could take 6 months to fix. More severe crowding issues could take closer to 12 months. Your dentist or orthodontist may recommend additional treatments — or even that you use a different treatment than Invisalign altogether.
The Invisalign website advises wearing the aligners for 20 to 22 hours per day, every day. Because they can be removed (to eat, drink, brush, or floss), treatment time depends partly on the wearer.
Some people’s teeth move faster than others. This is due to differences in bone structure, which vary from person to person.
Age can also play a role: adult teeth typically move slower than those of children or adolescents.
Because Invisalign aligners are removable, it's essential to keep track of them.
If you misplace your aligners, your dentist or orthodontist can always order new ones. But that means your treatment time will be extended while you wait for them to arrive.
Having multiple teeth alignment issues at once greatly complicates treatment. For example, if you have both an overbite and crowded teeth, you will need a tooth extraction before the overbite can be corrected.
Likewise, a large tooth gap in addition to an overbite will add to treatment time.
Orthodontists sometimes give varying timeframes for Invisalign treatment. Some give longer estimates in order to account for any possible delays or issues that may come up.
Others prescribe shorter treatment times to encourage the person to start treatment at their office (rather than someone else’s).

Invisalign aligners move your teeth between 0.25 to 0.3 millimeters every two weeks. This rate of movement is what your dentist or orthodontist uses to give you an estimate of how long treatment will take.
The aligners will only work as long as they are in contact with your teeth. The more time they spend outside your mouth, the longer treatment will take. They should only be removed for eating, drinking, brushing, or flossing.
If you don’t wear your aligners as prescribed, the teeth won’t rotate into the correct position. The teeth also won’t track with the next set of aligners, causing delays.
The average cost of Invisalign is between $3,000 and $9,000, which is comparable to traditional braces.
The exact price varies depending on the treatment time and the particular dental issues involved. There are varying costs (e.g., lab bills and retainers) depending on if you see an orthodontist or general dentist.
Most insurance plans cover Invisalign, and you can also pay for it with an HSA or FSA. Your dentist or orthodontist may also offer payment plans.

There are a few Invisalign alternatives. All of them are significantly less expensive and offer a variety of features, such as at-home impressions and remote monitoring.
Here are a few alternatives to Invisalign you should consider
Unlike other aligner brands, Candid only works with experienced orthodontists who design and monitor your treatment remotely.
Orthodontists specialize in straightening teeth to a greater degree than general dentists. This adds an extra layer of expertise to Candid treatment.
However, Invisalign is more suited for severe cases of malocclusion.
Invisalign aligners use buttons and/or elastics to treat severe teeth alignment issues. These buttons act as anchors for interarch bands that apply additional pressure to gradually reposition the jaw, providing more precise results. Candid doesn’t offer this.
Candid treatment is faster than Invisalign. The average treatment time for Candid aligners is 4 to 12 months. By comparison, Invisalign treatment can sometimes take 18 months or longer.
Candid can be more affordable: The aligners cost $3,300 (on average), whereas Invisalign can sometimes cost up to $8,000. However, these costs can vary widely depending on your insurance and care provider (along with other factors).
Finally, Invisalign treatment involves more in-office visits. Candid is a hybrid between in-office and at-home aligners: just one in-person visit is required for the initial consultation, along with one for a final post-treatment check-up.
The majority of treatment is monitored remotely by a Candid orthodontist.
Byte aligners are known for delivering straighter teeth in less time than other clear aligners brands. The average treatment time for Byte is 3 to 6 months on average, which is faster than any other aligner brand currently on the market.
With the HyperByte, a device that uses high-frequency vibrations to move teeth quickly, Byte treatment time is actually closer to 3 to 4 months.
However, it should be noted that there is currently no scientific proof of the safety and efficacy of moving teeth too quickly. Teeth realignment requires precise and accurate movement.
Byte currently costs $1,895 to $2,295, depending on whether you choose the day or night aligner option.
Note: NewMouth does not recommend night aligners because scientific evidence supporting their use is currently lacking at this time.
SmileDirectClub was the first company to introduce at-home aligners, making them a well-established brand.
Like Byte, SmileDirectClub offers both day and nighttime aligners. And similar to both Invisalign and Candid, they offer in-person consultations as well as remote monitoring of treatment.
Treatment time for SmileDirectClub is 4 to 6 months and currently costs $1,950 (payment plans are available).
