Duration of Invisalign® Treatment

Duration of Invisalign® Treatment

Oct 01, 2019

Not everyone is blessed with straight teeth and people with crooked teeth and misaligned bite often face dental issues. Apart from that, they also feel conscious of their smile. Though orthodontic treatment is a solution to their woes, many people avoid getting them as they don’t want to feel embarrassed because of metal wires and brackets, says the Grand Prairie dentist.


However, Invisalign has changed the face of orthodontic treatment, especially for teenagers and adults. They are a discreet and aesthetically appealing way of straightening teeth. When people decide to undergo orthodontic treatment with Invisalign, the first question that arises in mind is how long the treatment will last.

The fact is that there is no single answer to the question and it depends on the individual case. In simple cases, the treatment may take only six months and in complicated cases, it might take 18 months. In most of the cases, the treatment lasts between 12 to 18 months, says the dentist in Grand Prairie. It is to be noted that in more complex cases, the treatment can take 24 months or longer to be effective.

Also, some crowding cases may be too severe for the Invisalign to be effective and the orthodontists may recommend getting traditional braces or a combination of both the lines of treatments. There is no standard time as no two people have the same treatment needs, as everyone’s teeth are different which impacts the treatment time.

Why Does the Duration of Treatment Vary So Much?

Every person is different, so the orthodontists will advise differently on your specific needs and estimate how long the Invisalign treatment will take. The factors affecting the duration of the treatment include:

  • How much the teeth need to move for achieving the desired results.
  • The greater the distance teeth need to move, the longer the treatment time.
  • The pace at which the teeth move is different from one person to another.
  • It also depends on how complex is your case. Complex cases take a longer time for the treatment, says the dentist in 75052.
  • The duration of treatment also depends on how well the patient follows the instructions of the orthodontists such as wearing the aligners for at least 22 hours a day. People, who don’t wear the aligners for 22 hours, need a longer time for the treatment to be effective.

During the initial appointment, the orthodontists will give an idea of how long the Invisalign treatment will take. They create a treatment plan which includes information such as the estimated duration of treatment and the recommended treatment. They will also let you know the cost of treatment. If you wear the aligners as directed by the dentist, your treatment will be close to the orthodontist’s estimated time.

How Much Time is needed for Closing a Gap?

Invisalign can be used for closing the gaps between teeth but there can be some limitations. It can take almost 24 months for the Invisalign to close a gap size of 6mm. Small gaps may need a shorter time frame. Invisalign won’t be effective if there are single or multiple gaps in the top or bottom arch with more than 6mm distance.

How Much Time is needed for Crowded Teeth?

If the crowding is mild, it can take as little as 6 to 12 months for the Invisalign to treat crowding. More severe the crowding of teeth can make the duration of treatment longer. In severe crowding cases, Invisalign may not be the best treatment option. The dentist will either recommend other treatments along with Invisalign or suggest you to not go with Invisalign at all.

Is The Duration Longer For Getting Straight Teeth in Adults?

Invisalign doesn’t take long to treat adults as compared to children or teenagers. Everyone has different teeth and some people’s teeth move easily and others take a longer duration. Age is not a determining factor.

Recommended Time for Wearing Invisalign

It is said that one should wear Invisalign for 20 to 22 hours a day to be effective. One should remove them only while eating and brushing. You can’t decide if Invisalign is right for you? Only the dentist can help in deciding if they are ideal for you or not.
