New Smile with Clear Aligners (Invisalign)

Clear aligner technology like Invisalign, SureSmile, Angel Align, Spark, uLab Aligners, and ClearCorrect has revolutionized tooth alignment for new smiles. Search your orthodontist near you that offer aligner treatment. You want to visit best orthodontists to find the one that matches your needs.

Different aligners systems use clear plastic trays made from special materials like SmartTrack (Invisalign aligners) or Quartz. They are less noticeable than metal braces and make it easier to clean your teeth, improving oral health. However, if not removed regularly and maintained with good oral hygiene, clear aligners can be less effective than braces.

The treatment includes getting a new set of aligners every week to slowly move teeth into the right place. This is how clear aligners or Invisalign work to fix misalignment of crooked teeth. The process starts with digital scanning (iTero or 3shape) to identify dental problems.

The total treatment cost varies, with many providers offering a monthly payment plan to help manage healthcare expenses. How it works: Patients wear plastic aligners for 20-22 hours a day, switching to a new set as their teeth improve. This leads to a healthier, more attractive smile in 6-18 months.

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