As the leading name in clear aligners,

Invisalign’s advantages

are now very well known.

In fact, when I talk with patients,

the fact that it is not very noticeable

seems to appeal to many people.

But even now, when it comes to clear aligners,

there are still people who are skeptical

about how effective they are.

And many people worry that if they start

without fully understanding Invisalign’s disadvantages,

they may end up regretting it

after being dissatisfied with the results.

So today, I will honestly explain

the disadvantages of Invisalign

that you absolutely need to know.

You need 22 hours a day and a battle with yourself.

The biggest advantage, being removable,

is actually also the biggest disadvantage.

That is because Invisalign must be worn for at least 20 hours a day,

and the recommended wear time is 22 hours

for the teeth to move as planned.

In other words, except for meals and brushing,

it needs to be worn almost all the time.

The moment you think, “I’ll just take it out for a little while,”

teeth movement stops

and the plan begins to go off track.

In the end, this becomes the biggest reason

why the overall orthodontic treatment period

extends endlessly,

or why the desired results are not achieved.

If you do not have strong willpower and diligence,

Invisalign may end up being nothing more than

an expensive piece of plastic.

Orthodontic appliances that may be more noticeable than expected

In advertisements, Invisalign looks like nothing more than a clear

and smooth appliance.

But in most cases,

in order to move the teeth effectively,

a small resin bump called an "attachment"

must be placed on the tooth surface.

This attachment plays a very important role in increasing the appliance’s retention

and helping with precise movement,

but it can be more noticeable than expected

and may cause a foreign-body feeling on the lips.

It can also become discolored by coffee or curry.

If you thought, “No one will ever notice at all,”

you may feel disappointed at this point.

Not a universal solution for every case

Although Invisalign technology has advanced dramatically,

limitations still remain.

In cases such as treatment for severe protrusion that requires tooth extraction,

or complex skeletal malocclusions that need surgery,

a conventional orthodontic appliance may be more appropriate

depending on the case.

If a clinic recommends Invisalign for every case

without carefully considering the patient’s condition,

I would strongly suggest thinking it over again.

For orthodontics, or any procedure for that matter,

finding the method that suits you best

is what matters most

when it comes to achieving satisfying results.

That is why, even if you are considering Invisalign,

you should make sure whether it is truly the right method for you,

and whether you can accept Invisalign’s disadvantages.

Please be sure to check.

One more thing I would like to emphasize is that

the more precise the tool, like Invisalign,

the more the practitioner’s skill and philosophy

can affect your satisfaction.

In particular, the role of the medical team is to

diagnose the patient’s condition honestly,

and if Invisalign is one of the options,

to become a responsible partner who helps you

overcome all the inconvenience and difficulties

throughout the process.

That is why I hope you do not look for a place that simply gives you the appliance

and ends there.

At each regular visit, I hope you can find a place where the staff carefully checks wear time,

motivates you regarding the progress,

and has a medical team that stays with each patient.

A place like that is one that can sincerely think about

what method is best for you

and how to make treatment more comfortable for you,

and I am confident it is a place you can trust.

To summarize the conclusion again,

Invisalign definitely has disadvantages.

But those disadvantages can still be overcome,

depending on which doctor

and what system is used to manage the treatment.

That is why I want to emphasize once again

that it is important not to simply go to a place that sells appliances,

but to meet a medical team that will stay with you

until the end of your successful orthodontic journey.

This has been Oh Su-hwan, chief director of Smile D Dental Clinic. Thank you.
