Teeth whitening and removal of dental discoloration are common reasons for patients to visit the dentist. Additionally, the whitening procedure should not be considered in isolation, but as part of a larger treatment plan.

This 27-year-old patient came in to improve his smile. In particular, he wanted the teeth to become whiter and more harmoniously positioned.
We start with the upper jaw.
Photo 2
We started by temporarily filling the brown spots on teeth 22 and 23 and restoring the canines.
Photo 3
The patient wanted to eliminate these white spots on the central incisors and correct worn canines, which he described as “short.”

Dark spots tend to be more superficial than white spots.

Initial composite restorations on teeth 13, 22, 23, made before bleaching, will help us visualize the difference in tooth color.

Sandblasting. The white spots on the central incisor turned out to be so deep that even after various etching options they did not achieve the desired result. Therefore, it was decided to sandblast with aluminum dioxide particles (size 27 microns).

An error occurred at this stage. Having performed microabrasion, it was necessary to fill the defect with some kind of composite in addition to Icon, but this was not done.

Carrying out the whitening procedure
Diagnostics is the key point when carrying out the bleaching and infiltration procedure.
Sometimes we can correct our mistakes thanks to our skills. But, nevertheless, it is much better to avoid mistakes in advance than to look for a solution later!
Remember: you need to bleach before infiltration. If you used microabrasion, then you need to use a composite to replace tooth tissue.
A combination of bleaching and infiltration is a simple, conservative, and inexpensive solution to correct anterior dyschromia.
