Are you considering getting Invisalign to straighten your teeth? If so, you’re probably wondering how long the process takes and if it will be painful. Good news – we have some answers for you! Read on to learn more about Invisalign, including how long it takes and how much discomfort to expect during treatment.

What Is Invisalign?

Invisalign is an orthodontic treatment that uses a series of custom-made aligners to move teeth into their desired position gradually. The aligners are made of a clear, comfortable material that is virtually invisible when worn.

Invisalign is an effective and discreet alternative to traditional braces. It can correct many orthodontic issues, including overcrowded teeth, overbites, underbites, gaps between teeth, and more. With Invisalign, patients can achieve the smile they’ve always wanted without the discomfort and inconvenience of metal braces.

How Long Does Invisalign Hurt?

Invisalign can cause some discomfort during treatment, but the good news is that it is typically short-lived. Generally speaking, when wearing a new set of Invisalign aligners, patients may experience pain and discomfort for the first few days. The discomfort can vary from person to person, but most patients report that the pain is gone within a week.

After that, the pain should subside, and patients will feel more comfortable adjusting to their new aligners. As treatment progresses, discomfort should decrease, with only occasional soreness expected. It is important to note that while Invisalign may cause some discomfort during treatment, it is not overly painful and should not be unbearable.

Day 1: Initial Pain After Treatment

On the first day of your Invisalign treatment, you may experience discomfort or pain. This is normal and is caused by the pressure of the aligner on your teeth. This initial pain usually only lasts a few hours and is easily managed with over-the-counter pain medications such as ibuprofen or acetaminophen. If the pain persists or increases, you may consider contacting your Invisalign provider for further advice.

Days 2 & 3: Soreness and Occasional Discomfort

Patients may experience soreness, tenderness, and occasional discomfort for the first few days after beginning Invisalign treatment. This is normal and usually goes away within a few days. It is important to wear your aligners as prescribed by your orthodontist during this time.

Patients may also experience soreness in their gums or lips, especially when eating or drinking. This is due to the aligners pressing against the inside of the mouth. It is important to be gentle when brushing or flossing your teeth during this time, as the pressure from the aligners can cause further irritation.

Tylenol can help alleviate some of the pain associated with Invisalign, as well as over-the-counter topical numbing creams or gels. Additionally, patients can use cold compresses to ease discomfort in their mouths.

It is important to remember that this discomfort is temporary and will subside as your body and mouth adjusts to the aligners. If the discomfort continues for more than a few days, it is important to contact your orthodontist or dentist as soon as possible.

Days 4 to 7: Increasing Comfort

After the first few days of wearing your Invisalign aligners, you may notice that the discomfort and soreness are slowly subsiding. As your body adjusts to the trays, you may experience a decrease in the amount of pain you’re feeling. By the fourth day, you should feel almost no pain and have a high level of comfort when wearing your Invisalign aligners.

You may still feel occasional discomfort as you get used to the trays, but it should be minor and not cause concern. Contact your orthodontist to discuss possible solutions if you experience serious discomfort that does not go away after a few days.

It is still important to take good care of your aligners during this period of increasing comfort. Ensure you are brushing them regularly and attending all your appointments with your orthodontist. You should soon be completely comfortable with your Invisalign aligners with proper care and attention.

Week 2 and Beyond: Decreased Pain

As the weeks go on, your mouth will become increasingly adjusted to Invisalign trays. You may still experience slight soreness and discomfort when you initially put in a new tray, but the pain should begin to subside as you wear them more frequently. After two weeks, many people report only mild tenderness or no pain. At this point, you should notice a decrease in your pain levels and an increase in comfort.

If you continue to experience severe pain after two weeks, it is important to speak with your doctor about what can be done to relieve it. Over-the-counter remedies like ibuprofen, acetaminophen, or numbing gels can help reduce discomfort, but if you still feel discomfort after a few days, consult a medical professional.

Throughout Treatment: Varying Degrees of Pain

As you continue to wear your Invisalign aligners, you may experience varying levels of pain and discomfort. As your mouth adjusts to the new aligners, you may notice that your teeth are more sensitive when you first put them in. This is normal and should diminish over time. As you progress through your treatment, you may experience more frequent soreness and tenderness of the gums as your teeth move.

This is also normal and should gradually subside as your mouth adjusts to the new aligners. You may also experience pain or discomfort during specific activities such as eating or drinking. This is due to the pressure applied to your teeth as they shift into new positions. However, this, too, should diminish over time as your treatment progresses.

Causes of Unusual Pain During Invisalign Treatment

There are a few causes of unusual pain during Invisalign treatment. These can include an ill-fitting aligner, gum irritation, or an infection. If your aligner fits improperly, it can cause pain in the gums and teeth due to the pressure of the aligner pushing against them.

Also, it is possible for gums to become irritated when aligners rub against them. This can cause soreness and discomfort that may last for a few days. Finally, an infection can occur if oral hygiene is not maintained while using Invisalign aligners. This can cause pain in the mouth and gums and should be treated by a dentist or orthodontist as soon as possible.

Minimizing Invisalign Pain

When it comes to minimizing Invisalign pain, you can take a few steps to make your treatment more comfortable. First of all, ensure you wear the aligners for the right amount of time each day. The recommended time frame is at least 20-22 hours per day.

Rinse your aligners frequently in lukewarm water to keep them clean and free of bacteria. You can also use an antibacterial mouthwash to help keep your aligners free of bacteria and reduce any discomfort you may be feeling. Finally, take frequent breaks from your aligners, especially if you feel uncomfortable. Taking a break will allow your mouth and teeth to adjust to the new aligners and reduce the pain you may feel.

Over-the-Counter Solutions for Invisalign Discomfort

Over-the-counter solutions can help to reduce the discomfort caused by Invisalign aligners. Common remedies include using over-the-counter pain relievers such as ibuprofen and acetaminophen and an oral anti-inflammatory gel or ointment.

Also, using an oral rinse with a mild antiseptic can help to reduce the risk of infection and keep the mouth clean. It is important to note that these solutions should only be used if recommended by a doctor or dentist. Additionally, it is important to follow the instructions on the product labels and follow any advice from a medical professional.

Alternatives to Over-the-Counter Solutions for Treating Invisalign Discomfort

There are options for those looking for alternatives to over-the-counter solutions for treating Invisalign discomfort. For example, some patients find relief from cold compresses or ice packs applied directly to the sore area. Another option is to try using a saltwater rinse. Saltwater contains natural antibacterial properties that can help reduce swelling and pain.

When to Seek Medical Attention For Your Invisalign Discomfort

It is important to note that if you experience prolonged or unusual pain during your Invisalign treatment, you should seek a medical professional’s help. Pain or soreness that lasts beyond two weeks and is more severe than what you experienced initially or causes difficulty in everyday activities should be addressed by a specialist.

Your orthodontist or dentist can recommend additional treatments to help reduce your discomforts, such as special mouthwashes, oral rinses, or painkillers. They can also guide how to manage better the pain associated with Invisalign treatment.


In conclusion, Invisalign can cause discomfort for a few days after each new aligner is put in. However, this discomfort typically does not last longer than a week, and most patients report that the pain decreases throughout treatment.

While it’s normal to experience some discomfort during Invisalign treatment, it’s important to seek medical advice if you experience unusual pain or prolonged soreness. If you’re looking for ways to minimize the pain of Invisalign treatment, over-the-counter medications, cold compresses, and other alternatives can help alleviate any discomfort you experience.
