Invisalign® Clear Aligners

Invisalign can correct many of the same issues as traditional braces, using clear aligners rather than metal brackets and wires.

Common Dental Issues Corrected by Invisalign

  • Crowded or overlapping teeth — Crowded teeth can make brushing and flossing difficult, increasing the risk of decay and gum inflammation. Invisalign gently creates space so teeth can align properly and become easier to clean.
  • Gaps or spacing between teeth — Aligners can close spaces for both cosmetic improvement and gum health. Some patients also need space closed before future dental work, such as crowns or implants.
  • Teeth that shifted after braces  It’s common for teeth to move when retainers stop being worn. Invisalign is often used to correct these relapses quickly and discreetly.
  • Mild bite problems — Certain overbites, underbites, and crossbites can improve with aligners, which may also reduce uneven tooth wear or jaw strain.

If you’re not sure whether you qualify, Dr. Hu will take a digital scan and show you a preview of your smile before and after treatment. If your case is more complex, Dr. Hu will explain alternative orthodontic options or combination treatments. You'll choose the path that fits your timeline, budget, and goals.

The length of your clear aligner treatment varies significantly for each patient based on their needs. For example, a patient who needs to close a gap between front teeth will have a shorter treatment timeline than one who needs bite correction and tooth alignment. 

Compliance is also a factor in timely treatment with clear aligners. When you wear your clear aligners for 20-22 hours per day, you'll achieve results faster than someone who takes them out during the day.

Invisalign® Treatment Timelines

Here are some general guidelines for understanding clear aligner treatment timelines. However, the best way to determine how long your treatment will take is to schedule an evaluation with Dr. Hu. 

  • Closing gaps or minor adjustments — Minor treatment can take 3-6 months.
  • Moderate crowding or tooth alignment — Moderate tooth movement may take 6-12 months.
  • Complex cases with bite alignment needs — Complex cases may require anywhere from 12 to 24 months.
