Removing Spots on Teeth


Home  / Aesthetic Dentistry / ICON Infiltration Therapy

ICON infiltration therapy treats intrinsic (internal) stains in a gentle and aesthetic manner. Intrinsic stains are brown or white tooth discolourations on teeth. They can be spots or bands on the smooth surface of the tooth.

In the past, these spots or bands are removed by removing precious tooth structure and replacing that portion with a tooth-coloured restoration. Now, the infiltration technique allows unsightly stains to be successfully removed with teeth whitening and gentle infiltration therapy. It is painless since no drilling is required.

ICON Dental Treatment Procedure

1) The tooth is cleaned and prepared with etching gel to create porosity at the surface layer.

2) A liquid resin known as ICON is flowed into the porous enamel (outer tooth structure).

3) The resin is set with light.

4) We polish the ICON infiltrate (resin) that fills the discoloured spots.

The ICON infiltrate reflects light the same way as natural tooth enamel. The treated areas now appear visually similar to healthy tooth structure. If you wish to remove spots on your teeth, ask our dentists about gentle infiltration treatment with ICON today.
