Invisalign aligners, also referred to as clear aligners, exert controlled force on the teeth to facilitate their realignment. For some, this procedure is excruciatingly painful, while for others, it's barely noticeable. This may sound confusing, but it's not.
Invisalign is superior to other wire treatments because it moves individual teeth in the required direction without shifting the entire arch of teeth. While the intensity of pain is more noticeable when all teeth need to be opened or closed simultaneously, it is relatively less severe when only one or two teeth need to be moved.
Below, you can review the possible discomfort that a typical Invisalign treatment may cause.
What to expect in the early days
During the first three days of your Invisalign treatment, you may feel some minor discomfort as your aligners are adjusted. At this period, you might go through the following:
- 1. Day;
On the first day, your teeth will move slightly due to the pressure applied to the aligners; in the morning, you may experience a little tingling when you try to remove the aligners. Even biting into bread at breakfast may feel difficult on the first day.
- 2. Day;
On the second morning, you may wake up feeling a little more comfortable than the previous night. The second night may not be as arduous as anticipated, and typically, there is no terrible discomfort. However, it is normal to wake up several times during the night. Still, you might feel some pressure for a few seconds while you try to remove the plates. Most patients report that they have to cut out small snacks and divide their meals into smaller portions at this stage.
- 3. Day;
By the third day, it will feel much more comfortable, and you will use a lot less force in the morning to remove the plate than you did on the first two days. Although your front teeth might still be a little sensitive, breakfast gets easier and the pain is less severe than it was in the beginning. Over the course of the day, the pain becomes much less intense. It is now easier to remove and replace the plate than it was. After the first three days, the process actually gets easier, and you won't even notice it for a few weeks.
The forthcoming phase of Invisalign treatment
With each subsequent plate change after the first few days, you might feel a similar brief sensation of tightness; however, the second set of plates will typically feel much lighter than the first, and by the third set, you will hardly feel any pain at all. This discomfort is also a sign that your new plates are functioning properly and efficiently.
In a 2010 scientific study, Alexander D. Vardimon used strain measurements obtained to analyse the forces that Invisalign aligners exert on teeth. It was discovered that the first 24 hours following aligner placement saw the most noticeable tooth movement. This is the primary cause of the increased intensity of pain experienced on the first day. (1)
Frequently Asked Questions
Below you will find frequently asked questions and their answers.
Does Invisalign hurt? How much pain is involved?
Invisalign treatment can be painful. But how long it feels like pain varies from person to person; some say it's really painful and lasts four to seven days, while others say it's only two or three days.
When is Invisalign treatment painful?
As your teeth move around more, the pressure may also rise. With a new plate, a 0.2 mm movement is more painful than a 0.1 mm movement.
In addition, you may experience some discomfort while you become accustomed to inserting and removing the plates. With the first few plates removed, you may experience some throbbing sensation.
Does it hurt when you remove the clear aligners?
Yes, your teeth may ache a little when the plate is removed. A short, sharp agony is felt in the jaw as the pressure from your fingers is transferred to the teeth. However, this pain will subside after a few days.
Does every aligner hurt equally?
No. Since each aligner moves the teeth from a different position, the pain varies in intensity. Additionally, there are two methods used in Invisalign treatment: moving all of the teeth at once or moving just one tooth. When getting all of your teeth worked on at once, it can be hella painful.
Does Invisalign hurt more, or does metal braces treatment hurt more?
For most people, Invisalign is a far more pleasant and pain-free alternative to the more conventional metal braces. Typically, patients report more discomfort when using fixed appliances because of the stronger force applied to their teeth by the wires and elastics. The Invisalign aligner minimises discomfort by gently shifting teeth.
How long does the adjustment period last?
When a new plate is fitted, mild discomfort lasting a few days may be expected. It usually takes about three to seven days for most people to get used to it. After the first week, as the teeth become accustomed to the pressure of the plate, subsequent plates are much easier to fit.
