Nighttime Clear Aligners


What are Nighttime Clear Aligners? 

Nighttime clear aligners, also called night aligners, are clear aligner trays that you only wear while you are asleep. These aligners are created specifically for customers who have mild teeth crowding or minor gaps between their teeth. However, night aligners move your teeth slower than regular invisible aligners.

There are a few direct-to-consumer clear aligner brands that sell night aligners, including: 

Other brands, including Invisalign, Candid Co, and ClearCorrect, only sell traditional clear aligners. These aligners are worn for most of the day and while you are sleeping.  

Clear Aligners vs. Nighttime Aligners

The main difference between traditional aligners and nighttime aligners is how long they are worn each day and the length of treatment. 

Traditional aligners are worn for 22+ hours a day and are only removed for eating and cleaning. Night aligners are worn for 10+ hours a day, and treatment is typically longer. On average, traditional aligners take between 4 and 6 months to straighten your teeth. Night aligners take 8 to 12 months. 

If you have mild to moderate spacing issues and are seeking faster treatment, traditional clear aligners are the ideal option. If you have minor spacing issues and prefer to wear the aligners while you sleep, you may be a night aligner candidate. 

Nighttime aligners are great for people looking for a super discreet way to correct some minor orthodontic issues. You are able to easily eat and drink without removing trays and there will be no day-time adjustment. You can also incorporate your nighttime aligners into your daily evening routine as opposed to worrying about wearing them all day. 

It is essential to speak with a clear aligner specialist and orthodontist to determine the best choice. 

How Do Nighttime Clear Aligners Work?

To determine candidacy for night aligners, you can take a quiz online and order an impression kit. If you are approved for treatment, you have the option to order the aligners or skip treatment altogether. You can take the quiz for free on  

If you decide to order the aligners, you will receive them in the mail within 2 to 4 weeks (depending on the brand). Each set of aligners slowly moves your teeth. If you wear the aligners every day and for the right amount of time (10+ continuous hours), you will have a new smile in as little as four months. 

Throughout the treatment process, you’ll also set up virtual check-ups with a qualified dentist or orthodontist to ensure your teeth are moving correctly. One of these specialists oversees your treatment plan from start to finish. They will also show you virtual models of your teeth reset in small increments before moving onto the next set of aligners. 

Just like traditional teeth aligners, night aligners are made of thin, BPA-free plastic. The aligners are comfortable for nighttime wear.

Are Nighttime Clear Aligners Safe & Effective?

When monitored correctly, remote clear aligner treatment is safe and effective. Throughout treatment, you are overseen by a licensed and experienced dentist or orthodontist.

However, since treatment is monitored remotely rather than in-person (like Invisalign), there is a slightly higher risk of complications. 

Direct-to-consumer aligners can only treat minor teeth spacing issues. Some examples of this include some crooked teeth or small gaps between the teeth. You may not be eligible for treatment if you have moderate to severe teeth misalignment, such as an overbite, underbite, or jaw issues. 

Pros and Cons of Night Aligners

  • Only have to be worn at night, rather than during the day
  • 10+ hours of continuous wear (vs. 22+ hours for traditional aligners)
  • Affordable and convenient


  • Treatment takes longer than traditional aligners
  • Only minor cases of teeth misalignment are eligible
  • May cause more discomfort because your teeth are constantly being shifted
  • Accountability without the supervision of a direct dentist

What happens if you wear Invisalign only at night? 

Invisalign aligners are meant for daywear and nightwear (22+ hours a day). Wearing them only at night will interfere with tooth movement, resulting in delayed treatment time and likely require additional aligners to shift your teeth into the proper position.

Why You Should Trust Us 

All clear aligner products on this site are heavily researched, vetted, and reviewed before recommending them to readers. These are our standards for determining a reputable clear aligner brand:

  1. We figure out if the brand works with dentists or orthodontists. If they don’t work with licensed professionals in the industry, we do not recommend their products. This ensures customers receive the highest quality care and their treatment is overlooked by a licensed professional from start to finish. 
  2. We talk with company leaders to ensure the product is safe and effective. This may include asking for safety documentation and asking leaders about their manufacturing process. 
  3. We compare reviews from multiple sites. Our writers are instructed to read reviews and compare pros and cons. We clearly list the advantages and disadvantages of each clear aligner product to keep the content transparent. 
  4. We look into pricing and features. This ensures customers are getting the best quality products at reasonable prices.
  5. We check to make sure the customer service is high quality. We only recommend aligner brands that have clear instructions on how to contact them. Brands that offer “lifetime guarantees” are also well-respected. 

All clear aligner product pages are medically reviewed by a licensed dentist or orthodontist. Our dentists are specifically instructed to flag any recommendations they don’t agree with. Any products that don’t meet their high standards are removed.
