Over the last decade, clear aligners have grown in popularity as an alternative to traditional braces when it comes to straightening or realigning your teeth. The appeal of a less conspicuous and invasive design has attracted consumers that may not have previously considered braces.
First to the market was Align Technology in 1998 with Invisalign, with more clear aligners following including Spark, ClearCorrect, and uLab. Consumers like to reward innovators and today, the brand Invisalign has come to dominate this growing market internationally.
Invisalign is made from a flexible thermoplastic material named SmartTrack. Designed to be, as the name suggests, less noticeable than traditional braces, the clear coverings of an Invisalign aligner fit snuggly over teeth in order to re-align them.
Typically, Invisalign is used to address overcrowded teeth and other spacing issues, as well as some mild and moderate bite issues. While the product is still relatively new and for some it may be an appropriate treatment, Invisalign would not a successful procedure for everyone. As with any treatment that requires an investment of both time and money, it is recommended that you discuss your options with a qualified orthodontist.

Procedure
The first step in the process of undergoing an Invisalign procedure requires an appointment with an orthodontist. Your orthodontist will then create a 3-D image of your mouth and your jaw.
Once a 3D image has been created, your orthodontist will then design a plan to realign your teeth into a more correct position. The Invisalign plan will then create a series of customized plastic aligners designed based on your mouth, jaw and where the teeth are to be moved to.
The Invisalign aligners apply consistent pressure to your teeth, gradually shifting them and moving them into the desired places. Depending on your orthodontist’s instructions, you’ll change one set of aligners for a new set approximately every week or two.
It is generally suggested that you wear the aligners for at least 20 to 22 hours a day. The only time you would remove the aligners is when you are eating or cleaning the aligners.
Risks and Complications
Misalignment of the bite and jaw pain
Discolouration of teeth if not cleaned regularly
Increased risk of tooth decay if the teeth and aligner are not regularly cleaned
Gum irritation, though this is generally minor
Nerve damage, though this is usually only if the tooth was already damaged
FAQs
Q. How long is the Invisalign treatment for? A. The Invisalign treatment can be as little as 6 months, though the average time is between 12-18 months.
Q. How many hours a day do you wear an Invisalign a day? A. Invisalign aligners are typically recommended to be worn at least 22 hours a day for maximum effect. The maximum of two hours not wearing the aligner are for when you are eating or cleaning the aligner.
Q. Is having Invisalign a painful procedure? A. Invisalign is not a totally pain-free procedure, it’s common for teeth to feel sore and uncomfortable as you are moving your teeth into a new position. This is especially the case after using a new, tightened set of aligners. However, this procedure is more often described as sometimes uncomfortable, rather than painful.
Q. Is having Invisalign a procedure for anyone? A. Invisalign is a good choice for teens or adults who wish to correct small imperfections. However, it is not a recommended option for children or adults with severely crooked teeth or a severe overbite.
Q. Is having an Invisalign procedure safe? A. Generally, yes. However, your teeth and gums need to be in good health prior to starting Invisalign, as there is a slight increase in bacteria forming in your mouth, increasing the risk of tooth decay. You also need to be sure that you clean your teeth regularly and frequently as not only bacteria, but stains can build up on your teeth due to matter being trapped between your teeth and the aligner. If you follow your orthodontist’s instructions this is generally considered a safe procedure.
