Key Points

  • Invisalign uses custom clear aligners for teeth straightening while requiring careful monitoring of root health
  • Root resorption is a condition where tooth root structure breaks down, primarily affecting front teeth while sparing molars.
  • Careful monitoring, gentle forces, adequate rest periods, and proper wear compliance help minimize risks.
  • While painless at the root level, patients may experience tooth sensitivity and rarely mobility issues
  • Invisalign can be paused or stopped if needed, with plans to maintain current tooth positions

If you’re considering investing in clear aligner therapy, you likely prioritize both the aesthetic benefits of invisible treatment and the long-term health of your teeth. While root resorption occurs naturally throughout your life, orthodontic tooth movement can accelerate this process. While it is a gentler approach compared to traditional braces, clear aligner therapy still requires careful monitoring and management to protect the roots of your teeth.

Invisalign

Invisalign is a popular orthodontic treatment system that straightens your teeth by using a series of clear, removable aligners.[1] Invisalign aligners are custom-made plastic trays created from detailed 3D scans of your teeth. Each set of aligners makes small movements to gradually shift your teeth into their desired positions. You’ll wear each set for half a month before moving to the next set.

The aligners are nearly invisible when worn. This makes them a more aesthetically pleasing alternative to brace. They’re removable, so you can eat, drink, brush, and floss normally.

The treatment process begins with a consultation where your orthodontist takes digital scans and photos of your teeth. From there, they create a customized treatment plan that shows the step-by-step movement of your teeth. The aligners are then built specifically for you.

While Invisalign can treat many dental health issues, not everyone is a candidate. Complex cases might still require traditional orthodontic approaches.

Root Resorption

Root resorption is a condition where your body’s immune system begins breaking down and absorbing the root structure of your teeth. This process occurs naturally in baby teeth to make way for permanent teeth. When it happens to permanent teeth, it becomes a condition that requires orthodontic attention. This condition has many causes.[2] Root resorption during orthodontic treatment is rare, however, but is indeed possible.

Risk of Root Resorption

Maxillary incisors are most vulnerable to root resorption, particularly the central incisors.[4] Their single, tapered roots, the root length, and the amount of movement they often require during orthodontic treatment make them very susceptible.

Upper lateral incisors are also vulnerable. Their shorter, more delicate roots can be affected when significant tooth movement is needed.

Upper and lower premolars may experience root resorption, though less frequently than your front teeth. Canine teeth, despite often requiring substantial movement during orthodontic treatment, tend to be more resistant to root resorption. Their long, sturdy roots provide natural protection.

Molar teeth show the lowest incidence of significant root resorption. Their multiple roots and larger root surface area help distribute orthodontic forces more effectively. And teeth with unusual root shapes, previous trauma, or endodontic treatment may have an increased risk of root resorption regardless of their position in your mouth.

How Root Resorption is Prevented During Invisalign Treatment

Root resorption risks can be minimized during clear aligner therapy by utilizing several strategies:

  • Treatment planning and monitoring: Regular radiographic assessments help detect any early signs of root resorption[4], allowing for immediate intervention if needed.
  • Light forces: Clear aligners must only apply gentle, controlled pressure to move teeth gradually.
  • Treatment intervals: Teeth need adequate rest periods between active movements to prevent excessive stress on the periodontal ligament and root structures. Prescribed wear times and aligner change schedules should be followed closely.
  • Overall treatment duration: Extending treatment can increase resorption risks. However, moving too quickly must also be avoided.
  • Patient compliance: Wearing aligners as prescribed and attending regular monitoring appointments allows practitioners to ensure your treatment progresses safely. Any signs of sensitivity or mobility should be reported.
