Interested in Invisalign, but wondering, ‘Does Invisalign Hurt?” We get it – diving into the world of orthodontics, especially with something like Invisalign, can leave you with some questions especially around comfort. 

Invisalign is a discreet and innovative approach to orthodontics, which may come with mild discomfort. However, discomfort is often temporary and varies from person to person. 

Before you commit to Invisalign, view our in-depth guide on Invisalign comfort and pain to see if this orthodontic treatment is right for you!

1. Why Does Invisalign Cause Discomfort?

Invisalign may cause some discomfort because of the Invisalign process itself. Invisalign utilizes clear aligner material, applying a gentle and continuous force to shift teeth gradually. 

This approach, while highly effective, can lead to a mild tenderness or sensitivity during the initial stages of wearing new aligners. It’s important to note that this is a positive sign that your aligners are actively working to achieve the desired tooth movement.

2. Invisalign Pain in the First Week

As mentioned, it's common for individuals to experience some discomfort, especially during the initial week of wearing aligners. Understanding what to expect and how to manage this discomfort can help you navigate the early stages of your Invisalign treatment with confidence!

What to Expect:

Pressure and Tenderness:

  • In the first week, you may feel pressure and tenderness as your teeth begin to shift. This is a normal part of the adjustment process

  • The aligners work by applying gentle, controlled force to move your teeth, and this pressure can cause some initial discomfort.

Speech Impediments:

  • It's not uncommon to experience a slight lisp or difficulty pronouncing certain words when you first start wearing Invisalign aligners.

  • Your tongue may take some time to adjust to the presence of the aligners, but with practice, most people adapt quickly.

Initial Irritation to Gums and Tongue:

  • The edges of the aligners may initially irritate your gums, lips, or tongue. This is normal as your mouth gets accustomed to the presence of the aligners.

  • Rinsing your mouth with warm salt water can help alleviate any irritation and promote healing.

While the first week of wearing Invisalign aligners may bring some initial discomfort, it's important to remember that this is a temporary phase in your journey to a straighter smile. The benefits of Invisalign far outweigh the temporary inconveniences. 

3. Invisalign vs. Traditional Braces: Pain Comparison

Choosing the right orthodontic treatment is a significant decision, and one of the factors that often comes into play is the perceived pain associated with the process. Let’s look at the pain levels between Invdialign and brace.

Invisalign and Pain:

Invisalign is renowned for its comfort compared to traditional braces. The aligners are custom-made to fit snugly over your teeth, and the smooth, clear plastic minimizes friction and irritation.

While some initial discomfort is expected during the first few days of each new set of aligners, most users report that the pain is mild and short-lived.

The pressure applied by Invisalign is generally more gradual and constant, making the adjustment period more manageable.

Traditional Braces and Pain:

Traditional braces use brackets, wires, and bands to straighten teeth. The adjustment process can be more abrupt, causing higher initial discomfort compared to Invisalign.

Braces can cause soreness, particularly after adjustments made during orthodontic appointments. This discomfort can last a few days, and some users may find it challenging to eat certain foods during this time.

The presence of brackets and wires can sometimes lead to irritation of the cheeks and lips, requiring the use of orthodontic wax for relief.

While both Invisalign and traditional braces may cause some level of discomfort during the adjustment period, the general consensus is that Invisalign tends to be less painful. The individual experience varies, and factors such as pain tolerance, oral hygiene, and adherence to orthodontic guidelines play a role. 

4. The First Day with Invisalign

The first day with Invisalign marks the beginning of a transformative process, but for many, the first challenge is learning how to insert and remove the aligners. It might take a few attempts to become comfortable with the process, but practice makes perfect.

Your orthodontist will provide guidance on how to properly insert and remove the aligners, and it's crucial to follow their instructions for optimal results. Here are some tips for managing Invisalign discomfort.

Stay Hydrated:

  • Drinking water throughout the day helps keep your mouth hydrated and can alleviate any dryness or discomfort associated with the aligners.

  • Hydration also supports overall oral health and promotes a more comfortable Invisalign experience.

Follow the Wear Schedule:

  • Adhering to the recommended wear schedule is crucial for successful Invisalign treatment. Start with wearing the aligners for the prescribed amount of time each day, gradually increasing as advised by your orthodontist.

  • Consistent wear ensures that your teeth are receiving the necessary pressure for effective movement.

Practice Good Oral Hygiene:

  • Maintaining excellent oral hygiene is vital throughout your Invisalign journey. Brushing and flossing regularly, as well as cleaning your aligners, can help prevent any additional discomfort caused by plaque or debris.

5. When Does Invisalign Stop Hurting?

The discomfort associated with Invisalign is temporary and tends to improve as your treatment progresses. For most individuals, the pain diminishes significantly after the initial adjustment period of each new set of aligners. By the time you reach the end of your treatment, you'll likely find that any residual discomfort is minimal.

Initial Adjustment Period:

The first few days with a new set of aligners often bring some level of discomfort as your teeth begin to shift. This discomfort is typically mild and is a sign that the aligners are working to reposition your teeth.

The initial adjustment period varies for each individual, but it generally improves as your mouth becomes accustomed to the aligners.

Post-Appointment Soreness:

After orthodontic appointments where adjustments are made, you may experience increased discomfort. This is a normal response to the additional pressure applied to guide your teeth into the desired positions.

Over-the-counter pain relievers, as recommended by your orthodontist, can be helpful during these periods.

Alignment Progress:

As your teeth continue to move and align, the discomfort tends to decrease over time. Many individuals report that the pain becomes less noticeable with each new set of aligners.

The body's natural adaptation to changes in dental alignment contributes to a reduction in discomfort as treatment progresses.

The Big Takeaway


Invisalign discomfort is temporary, signaling the positive progress of teeth realignment. Consistency in following the wear schedule, effective communication with your orthodontist, and maintaining excellent oral hygiene are pivotal for a smoother experience. 

Remember, the initial discomfort lessens over time, so try to be patient and celebrate the transformative journey toward a more confident smile. 

The key lies in embracing the process and staying focused on the end goal, as the rewards of a beautifully aligned smile make the temporary discomfort well worth it!
