Frequently Asked Questions about Invisalign

1. What is Invisalign?

Invisalign system is a series of custom-made plastic aligners which straighten teeth by incremental teeth movements. They are virtually invisible, made of a clear, non-toxic, BPA-free (Bisphenol A), thermoplastic material totally compatible with your mouth tissues. Invisalign uses advanced 3D computer imaging technology to show your complete treatment plan, from your current teeth position to the final desired position. This means you are able to see how your smile is going to look like at the end of treatment even before starting wearing your aligners.Invisalign Invisible Braces

2. What are the benefits of using Invisalign?

  • Invisalign treatment is fast and accurate.
  • It uses a virtual treatment plan enabling you to see how your smile is going to look like at the end of treatment.

There are multiple benefits of using Invisalign aligners:

  • Invisalign aligners are virtually invisible. They do not affect your aesthetics and lifestyle.
  • They are made of a soft, thermoplastic, bio-compatible plastic which is very comfortable to use.
  • They are free of any metal brackets or wire which irritate your gums.
  • They are removable. You can remove them when eating, brushing and flossing.
  • They do not interfere with your oral hygiene practices.

3. How does Invisalign work?

The treatment process involves taking an impression of the patient’s teeth and scanning them to get a 3-dimensional computerized model. A software application is then used to show how teeth should be moved in increments between the current and the desired positions. This 3D computer projection is used as a basis for developing custom-made aligners using computer-aided design/computer-aided manufacturing (CAD/CAM) techniques.

4. Is this a new technology to straighten teeth?

Yes, it is a relatively new orthodontic technology to straighten teeth. In 1945, an American orthodontist Dr. H.D. Kesling envisioned that one day modern technology would be able to bring about teeth movements which are required for a comprehensive orthodontic treatment. Align Technologies made this vision come true by introducing Invisalign in 1997.

5. Are there any aesthetic concerns?

No, there are no aesthetic concerns because these aligners are virtually invisible.

6. How do I know if I am a suitable candidate for Invisalign or not?

A visit to our practice and having a dental examination are the best ways to find out whether Invisalign is right for you. Dr. Le will conduct a brief suitability assessment and answer your queries regarding Invisalign.

7. What problems can Invisalign correct?

Invisalign can effectively correct mild to moderate orthodontic problems such as crowding, spacing, deep bite/over bite, under bite, crossbite and mild relapse after removing conventional metal braces.

8. Will it work for me?

Invisalign is what you have been looking for if you have

  • Crowded teeth: Crowding is the condition in which there is a lack of enough space in the jaws for all the teeth to fit comfortably. Crowding of 1 to 5 millimeters can be corrected by using Invisalign.
  • Spaced teeth: This is when there is excess space in the jaws leading to wide gaps between teeth.
  • Crossbite: Crossbite is a form of malocclusion in which the normal relationship between the upper and lower teeth is reversed and lower teeth extend outer to the upper teeth.
  • Deep bite: Deep bite is a type of malocclusion in which there is an increased vertical overlap between the upper and lower teeth.
  • Mild relapse after the removal of conventional braces.

 9. Will I experience any pain with these aligners?

No, Invisalign aligners are not painful. You may experience an initial mild discomfort which usually goes away in a couple of days.

10. Will these aligners affect my speech and lifestyle?

Invisalign aligners may affect the quality of speech temporarily for some days. Any lisp or speech defect disappears as you get used to wearing these aligners. It affects your speech for just 2 to 3 days.

11. How long does treatment take?

The time taken by Invisalign aligners to straighten teeth varies from person to person depending upon complexity of the problem. Average time taken by these aligners to move teeth to desired position is 13 to 14 months.
