Frequently Asked Questions


What is Invisalign®?

  • Invisalign® is the clinically proven, nearly invisible way to straighten teeth without metal braces.
  • You wear a series of clear, removable aligners which gradually move your teeth into the desired position. The aligners can be removed for eating and cleaning.

How does it work?

  • Based on our Dr. Fellerman's diagnosis, a series of aligners are custom made in a laboratory using advanced computer imaging technology.
  • You wear each aligner for two weeks before being replaced with the next one, until your teeth are straight.

Why should I select Invisalign®?

  • Aligners are nearly Invisible - straighten your teeth without anyone noticing.
  • Aligners are Comfortable – there are no wires or metal to cause mouth abrasions.
  • Aligners are Removable – for eating, drinking, dental care or other activities.
  • Better oral hygiene during treatment – brush and floss normally to maintain healthy gums and teeth.

Will it work for me?

  • If you have all your adult teeth (fully-erupted molars), most patients can be treated with Invisalign® even if they have crowns or bridges.
  • Many common issues like crooked or crowded teeth, spaces between teeth and certain overbite and crossbite types can successfully be corrected.

Is this treatment only for adults?

  • No, you just need to have all your adult / permanent teeth (fully erupted molars).
  • & be committed to wearing your aligners at all times except for eating, drinking and cleaning.

How do I get started?

  • After your initial evaluation with Tricia or Dr Fellerman, we discuss your goals for a new smile.
  • We plan your full treatment together, and take your impressions and photographs.
  • With advanced computer technology we can then show you a 3D generated model of how you could look, before you start your treatment.

How long does the treatment take?

  • Depending on complexity, most treatments will take 11 – 18 months.

How long do I have to wear the aligners?

  • The aligners should be worn for 22 to 23 hours a day for the best results.
  • Every 2 weeks you change to a new aligner and we recommend visits to monitor progress approximately once every 6–8 weeks.

Are the aligners really Invisible?

  • The aligners are made from a clear plastic ( SmartTrack Aligner Material), so they are nearly invisible.
  • Even when very close, most people will not notice you are straightening your teeth – unless you tell them!

Can I eat and drink with my aligners?

  • No. The aligners are removable so you can still enjoy your favourite food and drinks.
  • You need to avoid tooth decay and /or gum disease by not forcing the food particles and sugars against your teeth via the aligners. So keeping them clean is important.

Do the aligners hurt?

  • It is normal that you will only feel temporary discomfort when you wear the aligners for the first day or two.
  • The smooth aligners are not harmful to the inside of your mouth, but you do feel pressure and this is a good sign that the aligners are working.

Are there any side effects?

  • As with conventional treatments, you may feel a slight pressure at first.
  • Aligners may temporarily affect the speech of some people, and you may have a slight lisp for a day or two.

How old is this technology?

  • Align Technology, Inc., the company that manufactures Invisalign®, was founded in 1997.
  • Since then over one million people have been in treated with Invisalign®.
