Crooked teeth, spacing, overbite, overcrowding, and crossbite are the most common orthodontic conditions experienced by a large proportion of the population. Luckily, there are dozens of treatment options available, Invisalign being of them.

Invisalign is a modern alternative to metal braces that utilizes computer software to produce a 3D virtual treatment plan. It is made of a patented thermoplastic material that is invisible and customized to fit the patient’s mouth molding.

The device uses SmartTrack and SmartForce technologies to help predict your teeth’s movements. Invisalign gently aligns your teeth over time and is frequently changed, depending on the scope of work needed and your orthodontist’s treatment plan.

Types of Invisalign

Invisalign comes in various types for different orthodontic issues as summarized below;-  

Invisalign Express  

This Invisalign option is ideal for persons with minor spacing or crowding issues. It is also prescribed for teeth straightening in individuals set to undergo restorative surgeries such as composite bonding or tooth veneers. Invisalign Express offers the shortest treatment period.

Invisalign i7

Also intended for minor orthodontic conditions, Invisalign i7 is best for beautification procedures that require minimal treatment. It is the perfect solution for slightly crooked or overcrowded front teeth as it is removable and nearly invisible. Being relatively new, Invisalign i7 is expensive and with minimal benefits.

Invisalign Lite

The Invisalign Lite type is reserved for moderate cases such as crowding, minor spacing, and malocclusion (one has a regular bite, but the upper teeth slightly overlap the front lower teeth).

This option is cheaper and offers up to 14 aligners. It may take 6 to 9 months to align your teeth properly.

Invisalign Teen 

Teenagers experience a continual shift in their teeth as they grow and develop. For this reason, Invisalign Teen with six complimentary replacements and tooth eruption tabs is the perfect option for adolescents.

The aligners have to be replaced every two weeks and must always be worn except when playing, eating, brushing, and flossing. In most cases, treatment takes up to one year, though the treatment period dramatically varies.

Invisalign Full

This is the most prescribed treatment approach, as it is ideal for the most severe and complex cases. Invisalign includes several aligners based on the treatment plan and the severity of your condition. It may take between 12 to 18 months to have your teeth fixed.

Pros and Cons 

Both Invisalign and braces help align teeth by correcting most orthodontic issues, including spacing, bites, and crowding. However, Invisalign offers benefits compared to braces. Despite its great profile, Invisalign also has its set of drawbacks.


  • Removable
  • One can eat any food, including gum and popcorns
  • Not visible to others
  • Allows flossing, whitening, and brushing
  • Offer maximum comfort


  • Costly
  • In some instances may take longer than braces
  • Not an option in some complicated cases
  • Requires compliance and discipline
  • Possibility of losing or breaking trays


Advancements in technology have made it easier to correct common orthodontic conditions. The Invisalign treatment option is comfortable and does not limit one on their eating and mouth hygiene habits. It comes in five types, each designed for specific conditions.
