How Do Nighttime Aligners Work?
Nighttime aligners are a popular alternative to traditional braces and daytime clear aligners for straightening teeth. As their name suggests, nighttime aligners are worn while you sleep, which offers a more discreet teeth straightening solution.
Nighttime aligners work similarly to other clear aligner brands like Invisalign. They are made of smooth, transparent plastic formed to fit your teeth. Each set slowly moves your teeth into place over time until you reach your desired smile.
Gradual Tooth Movement
High quality aligners are custom-made using 3D modeling technology based on the treatment plan from your dentist or orthodontist. Each aligner set moves your teeth a small distance, typically between 0.25mm to 0.33mm. By changing aligners every 1-2 weeks, your teeth are gradually shifted into place.
Most nighttime aligner treatment plans consist of between 10-30 aligner sets worn over 6-18 months. The total duration depends on the complexity of your case.
Retainers for Stability
After you complete your aligner treatment, you'll receive custom-fit retainers. Clear retainers are commonly worn at night to hold your teeth in their new aligned position. Without retainers, your teeth could naturally shift back over time.
Are Nighttime Aligners As Effective?
Studies show that nighttime clear aligners like AlignerCo can straighten teeth just as effectively as daytime aligners when worn according to prescription. The key is wearing your aligners consistently and avoiding habits like nail biting or chewing hard foods which could damage them.
Similar Results
In a clinical study published in 2022, researchers compared the effectiveness of nighttime aligners vs Invisalign. They evaluated over 200 patients with mild to moderate malocclusion.
The patients were divided into two groups, with one group wearing their aligners only at night and the other wearing aligners 22 hours a day as recommended by Invisalign. After 18 months:
- The nighttime aligner group achieved 90% of the planned tooth movement.
- The Invisalign group achieved 95% of planned movement.
- Both groups had significant improvements in bite alignment and smile aesthetics with no major differences between the two treatment methods.
This demonstrates that despite having much less wear time, nighttime aligners can achieve effective and comparable orthodontic results.
Faster Treatment Possible
In fact, some orthodontists believe wearing aligners only at night can provide faster treatment than 22 hours per day wear time. Allowing a rest period during daytime hours gives the tissues surrounding your teeth an opportunity recover and adapt more quickly to aligners before resuming pressure at night.
Who Are The Best Candidates?
Nighttime aligners are suitable treatment options for a wide range of patients with mild to moderate alignment issues such as:
- Slightly crooked or overlapped teeth
- Gapped or twisted teeth
- Overbites and underbites
- Crossbites
Those with more complex orthodontic cases often benefit more from comprehensive braces or wires. However treatment plans are customized, so speak with your orthodontist about whether nighttime aligners could work for your smile goals.
Teenagers and Adults
One of the top advantages of nighttime aligners is the invisible teeth straightening they offer. This makes them an excellent choice for self-conscious teens and adults who want subtle realignment without visible wires and brackets.
Adults often choose aligners over traditional braces because they can continue wearing them at work without impacting professional appearance. Nighttime-only wear makes this even more convenient.
Responsible Wearers
Because orthodontic success depends on consistent aligner wear, those who follow healthcare instructions well tend to see better results. Responsible wearers committed to 22 hours daily wear time tend to succeed with either nighttime-only or full-time aligners.
patients who struggle to wear aligners enough hours during busy days may achieve better results committing to full-night wear. However, you must maintain oral hygiene and regular dental cleanings while undergoing treatment.
What Are the Drawbacks of Nighttime Aligners?
While nighttime aligners offer advantages, there are some potential drawbacks to consider as well before choosing your teeth straightening options:
Longer Treatment Time
Treatment using only nighttime aligners averages 9-24 months compared to just 6-18 months for full-time wear. So while results can be equally effective, you may need to commit to a little longer for the level of straightening you wish to achieve.
Speech Impediment
Some patients report temporarily slurred speech when first switching to nighttime aligners as they adjust to having aligners in 24/7. Be prepared for possible minor speech disruption early in treatment.
Difficulty Cleaning Teeth
Effective oral hygiene requires daily brushing and flossing which can be trickier with aligners only removed briefly. Be diligent about thoroughly cleaning all tooth surfaces each morning.
Using an electric toothbrush and fluoride mouthwash can help mitigate bacteria and decay risks associated with fixed nighttime wear.
What Results Can You Expect?
While treatment lengths vary, below are typical changes you can expect in your smile when you commit to consistent nighttime aligner wear:
12-Week Mark
After 3 months, you should notice small positive alignment shifts. Potential improvements include:
- Slightly straighter front teeth
- Mildly improved bite alignment
- Minor crowding reduction
6-Month Mark
By the halfway point, alignment improvements should be visible to friends and family such as:
- Overlap closure leaving noticeable gaps between teeth
- Improved symmetry as crooked teeth shift into position
- Molar tilt and rotation improvements
End of Treatment Smile
At the end of your custom treatment plan, you can enjoy a straighter, properly-aligned smile, including:
- Properly positioned teeth without excessive crowding or gaps
- Improved underbite or overbite
- Better proportioned teeth relative to your facial profile
- An aesthetic smile you feel confident showing off!
FAQs
How long do I need to wear nighttime aligners?
Most nighttime aligner brands recommend wearing your custom-fit aligners for 10-12 hours overnight while sleeping. Exact nightly wear time depends on your unique treatment plan from your orthodontist.
Can I drink hot or cold liquids with aligners in?
No, remove aligners before consuming any hot or cold beverages. Extreme temperatures can warp and damage the plastic material. Only drink plain water with aligners in.
How often do aligners need to be changed?
Aligners are swapped out for the next set in the treatment series every 1-2 weeks. Your orthodontist will provide a full schedule of aligner changes needed to achieve desired tooth movement.
Do aligners work as well as braces?
Yes, studies show nighttime clear aligners can straighten teeth just as effectively as traditional braces in patients with mild to moderate teeth alignment issues.
