Porcelain shells are individually made thin layers that are stuck on the tooth by the dentist.
Shells are put on teeth that don’t react properly on tooth whitening, have shape irregularity, discolored or have white or yellowish brown spots due to fluorosis.
The biggest advantage of porcelain shells is that they can be prepared with no or little tooth material waste. The shells are made with two techniques.
One of them is the direct shell which is made by the dentist by herself sampling it directly to the mouth. The other is the indirect one which is made dentistry laboratory fallowing a preparation requiring a little tooth material waste.
