You’re interested in getting a perfect smile without dealing with a mouthful of braces for years on end. Clear aligners seem like an ideal solution – nearly invisible, comfortable, and able to straighten your teeth over time. But you might still be wondering whether aligners can fix an overbite or an open bite?

The truth is, while aligners have come a long way and can correct many common problems, there are some limitations. Before you decide to go with clear aligners, you need to understand what issues they can solve effectively to achieve the best results.

How Do Clear Aligners Work?

Clear aligners offer an effective alternative to traditional braces for teeth straightening. Wearing aligners for 20-22 hours daily is crucial. Consistency in removing them only for eating or oral hygiene is vital to avoid elongating the treatment period.

Initial Consultation

An initial consultation and clinical assessments, including x-rays and digital scans, determine aligner suitability based on the required correction.

Custom Treatment Process

A personalized treatment plan involves 3D scans used to create tailored, BPA-free thermoplastic aligners for precise teeth straightening.

Aligner Usage and Care

Regularly changing aligners (every 1-2 weeks) as advised is essential. Consistent wear is important, while neglecting wear time can reduce effectiveness.

Ongoing Dental Monitoring

Regular dental check-ups (every six weeks) are crucial to maintain oral health and prevent issues like plaque buildup and cavities. Proper care and cleaning of the aligners are also essential to maintain their quality.

Orthodontic Issues Fixed by Clear Aligners

Do you struggle with an underbite, overbite, or open bite? Are gaps in your teeth or crowded teeth impacting your confidence? If any of these orthodontic issues resonate with you, there is good news – clear aligners can effectively fix these problems!

  • Crooked Teeth: Clear aligners are a great solution for fixing crooked teeth. With their discreet appearance, you won’t have to worry about the unsightly metal brackets and wires of traditional braces.
  • Underbite: An underbite occurs when the lower teeth extend beyond the upper teeth. By using a series of custom-made aligners, your underbite can be corrected, providing you with an improved speech and balanced smile.
  • Overbite: Overbites, where the upper teeth extend too far forward, can be corrected with clear aligners as well. By gently guiding the teeth into the right position, aligners can gradually reduce the overbite, improving both the aesthetics and functionality of your smile.
  • Open Bite: An open bite is characterized by a gap between the upper and lower teeth when the mouth is closed. Clear aligners can help close this gap by bringing the upper and lower teeth into proper alignment.
  • Crossbite: A crossbite occurs when the upper teeth sit inside the lower teeth when the mouth is closed. This misalignment can lead to gum issues if left unaddressed.
  • Spacing in Teeth: Clear aligners can effectively close gaps between teeth by gently moving them closer together. Whether you have gaps due to missing teeth or naturally occurring spacing issues, aligners can discreetly and effectively close those gaps, creating a more aesthetically pleasing smile.
  • Crowded Teeth: If your teeth are overcrowded and overlapping, they may lead to tooth decay, gum disease, and difficulty in cleaning. By gently shifting the teeth into their proper positions, the aligners can create the necessary space within your mouth.

Orthodontic Problems That Aligners Can’t Fix

Clear aligners have revolutionized orthodontic treatment, offering a discreet and convenient option for achieving a straighter smile. However, while they are highly effective for many cases, there are certain orthodontic issues that cannot be fixed by clear aligners alone.

  • Shape of the Teeth: If you have short, round, peg-shaped, or overly pointed teeth, the aligners may not be able to achieve a secure grip, hindering their ability to move your teeth into the desired position. In such cases, alternative treatment options may need to be considered.
  • Position of the Teeth: When teeth are overcrowded, they can shift into alternative positions, making it challenging for clear aligners to achieve the desired alignment. If the rotation of teeth, particularly molars or canines, exceeds 20 degrees, clear aligners may not be able to move them in the right direction.
  • Large Spaces Between Teeth: While aligners can easily close small to moderate gaps of up to 6mm per arch (top or bottom), larger gaps may require alternative treatment methods.
  • Intrusion and Extrusion: Orthodontic treatment can involve moving teeth vertically, raising or lowering their position in the jawbone. This is an essential aspect of achieving a harmonious smile, where the height of all your teeth is the same.
  • Midline Shift: For patients with front teeth that do not align with the midline of their smile, clear aligners can provide correction by up to 2mm to the right or left per arch. This can help achieve a more symmetrical smile. However, if the misalignment exceeds this range, orthodontists may recommend traditional braces as the more suitable treatment option.
  • Existing Dental Work: Certain dental work, such as dental bridges, porcelain veneers, or crowns, can pose challenges when it comes to using clear aligners. Clear aligner attachments, which help facilitate tooth movement, may not bond securely to surfaces that have dental restorations.


So, there you have it, a quick overview of what clear aligners can and can’t fix. While they’re great for minor to moderate orthodontic issues, more severe cases typically still require traditional braces. The good news is that clear aligners have come a long way and continue to expand the range of issues they can effectively treat.
