New Smile with Clear Aligners

Achieving a new smile through tooth alignment has been revolutionized by the advent of clear aligner technology, such as Invisalign clear aligners, SureSmile aligners, Angel Aligners, Spark, uLab Aligners, ClearCorrect and more.

These systems use a series of custom-made, thermoplastic aligners, crafted using plastic materials like SmartTrack or Quartz. Unlike traditional methods that rely on metal brackets, this clear aligner system is partially invisible with likely better oral health and periodontal care by allowing easier cleaning and maintenance. It is important to mention that clear aligners could be worse than braces if they are not removed regularly and the oral hygiene doesn't maintained well.

The treatment involves receiving a new set of aligners, typically every week, which gently shift teeth into the desired position. The process is mapped out from the start using a digital scanning (iTero or 3shape), illustrating how Invisalign work to correct various dental issues. The Invisalign system and similar options like ClearCorrect provide clear, step-by-step guidance on tooth alignment.

The total treatment cost varies, with many providers offering a monthly payment plan to help manage healthcare expenses. How it works: patients wear each set of plastic aligners for the recommended period, usually 20 to 22 hours a day, advancing to a new set as their teeth alignment improves, leading to a healthier, more attractive smile typically within 6 to 18 months.

Clear aligners aka Invisalign is a great choice for the right patient of all ages - kids, teens and adults.
