What is Invisalign?

For patients who want to straighten their teeth with clear aligners, they need to know what is Invisalign and what it does. There nothing as attractive as a straight and white smile, backed up by healthy teeth.

For people who would like straight teeth and a flawless smile, Invisalign could be the perfect solution. While metal braces were previously the only way to straighten teeth, this innovative new method has revolutionised orthodontics for millions of people.

The issues that Invisalign can resolve are:

  • Overcrowding – when there is limited space in the jaw to fit all teeth comfortably and normally
  • Crossbites – When upper and lower jaws are not aligned properly
  • Underbites – Lower teeth stick out past those at the front of the mouth
  • Overbites – When the upper teeth stick out over the lower ones
  • Widely-spaced teeth – Gaps that need to be closed to ensure teeth are properly aligned and food packing does not occur.


Invisalign clear aligners are worn for 20-22 hours a day and changed every 2 weeks, and the next aligner in the set is then worn. Every 6 weeks the patient needs to see their Invisalign dentist for a review. It is very important that each aligner is worn for 20-22 hours a day and 2 weeks per aligner for the Invisalign treatment to work well.


Invisalign aligners are removable and the patient must remove them to eat and drink food and to clean their teeth. Drinking water whilst wearing aligners is fine. When the aligners are worn for the first time, there maybe some mild discomfort experienced as the teeth are slowly moved into their ideal position. Also patients may notice slight lisping when speaking with new aligners, however this usually settles after a few days of wearing the new aligners.  Once the treatment is finished, its important that retainers are worn at night, to prevent relapse.
