    2. Impressions & Digital Treatment Plan

    If you’re a good candidate, we’ll take precise digital scans or impressions of your teeth to create a customized treatment plan. Using advanced 3D technology, Dr. Duong Ly designs the step-by-step movements of your smile for predictable, beautiful results.

    3. Review & Approval of Your Digital Plan

    Once your digital treatment plan is ready, Dr. Duong Ly will review it with you in detail. You’ll see a preview of your new smile, and once you approve the plan, your custom clear aligners will be fabricated to begin your transformation.

    4. Receive & Begin Wearing Your Aligners

    When your custom clear aligners arrive, it’s time to start your treatment! Your aligners are comfortable, discreet, and removable — simply take them out when eating or brushing, and wear them as directed to keep your smile progressing on schedule.

Occasionally, small tooth-colored attachments may be placed on certain teeth to help your aligners move them more precisely and efficiently, ensuring faster and more predictable results. Throughout your treatment, you’ll have regular progress visits every 4–6 weeks so Dr. Duong Ly can monitor your smile, provide your next set of trays, and keep your treatment on track.

Dental Clear Aligners FAQ

  • Every aligner treatment is unique, and the timeline depends on your specific smile goals and the complexity of your case. On average, most patients complete Invisalign or clear aligner treatment within 12 to 18 months, though some may achieve their desired results in as little as six months. During your consultation, Dr. Duong Ly will provide a personalized estimate and guide you through each stage of your treatment plan.

  • Proper care and consistency are key to achieving your best smile:

    • Wear your aligners 22 hours a day. Consistent use is essential for effective tooth movement.

    • Change aligners weekly or biweekly as directed in your personalized treatment plan.

    • Remove aligners before eating or drinking anything other than water to prevent staining or damage.

    • Brush and floss before reinserting your aligners to maintain excellent oral hygiene and prevent decay.

    • Attend regular checkups every 4–6 weeks so Dr. Duong Ly can monitor your progress and provide your next set of trays.

    Following these steps helps ensure your clear aligner treatment stays on track and delivers the beautiful, healthy smile you’ve been waiting for.

  • Many patients start to see noticeable improvements within the first few weeks of treatment, with most achieving their final results in 12 to 18 months, depending on their individual needs. Using advanced digital planning, Dr. Duong Ly maps out each precise movement of your teeth and shows you a preview of your expected final smile before treatment even begins. Viewing real before-and-after transformations can help you set realistic expectations — and get excited about the beautiful, confident smile your clear aligners can achieve.
