How to fix black triangles after Invisalign treatment?

Doctor's Answers 1

Thank you for your questions. Black triangles often appears after alignment in areas where there were previous overlapping of teeth, especially in adult patients. These black triangles can be minimized by doing some reshaping between teeth or what is commonly known as IPR (interproximal reduction) so that teeth can come closer together and minimize the black triangles.

However, if the black triangles are very broad, they may not be eliminated totally through IPR as we can only remove 0.25mm of enamel per tooth surface so that not to cause damage or sensitivity to the tooth itself. However, the black triangles can be minimize in this method.

Good and proper hygiene methods are crucial to minimize black triangles as improper use of dental tools or not cleaning these spaces properly can result in plaque build up and gum recession, which will cause enlargement of the black triangular spaces.

I would strongly suggest that you discuss your concerns with your orthodontist so that he or she can address them and plan your treatment accordingly.

Warmest regards,

How does ClinCheck help with Invisalign treatment?

Thank you for your question. Clincheck is a proprietary software of Invisalign, it is a 3D visual interface that allows your doctor to assess the planned teeth movement, make adjustments to the teeth position as well as add or change the attachments to be bonded on the tooth. In Invisalign treatment, a scan/impression is taken of your original teeth position. This is then translated to a virtual 3D model where the technicians will move the teeth into the desired position based on your dentist/orthodontist's treatment plan.

How do dentists determine the amount of space needed to fix an overbite? (photos)

The decision to extract, or not to extract, for any case depends on several factors, such as the facial and lip profile (e. g. are the lips protruding?) the amount of overlap or crowding of the teeth, how much the teeth are flared forward with respect to the bone, etc. Patients with a substantial overjet would more often have lips that unable to close due to the teeth which are sticking out. In situations like this, extractions will result in a more aesthetic or pleasing outcome.
