The re-contouring (or indeed sometimes more advanced treatment) is often needed in adults after orthodontics, to make the teeth look their absolute best. The reason for this is that during their lifetime the teeth wear down asymmetrically, especially if they are crooked to begin with.

The need for this (if any) should be assessed at your initial consultation. Please note that sometimes orthodontists do not spot this or they are not trained to discuss any restorative cosmetic dentistry techniques. So ask the dentist or orthodontist and they can refer you if required before you actually order and begin the Invisalign. If a cosmetic dentist is doing the treatment then they often will discuss this and plan any further procedures at the same time.

I hope that makes sense? You can always email me a photo of your teeth for my advice: [email protected]. Kind regards, Mark.
