There are several types of cosmetic dental veneers, including:

1- Veneer: It is a very thin veneer with a thickness of 0.3-0.7 mm, placed on the front surface of the teeth and used to improve the color and external appearance of the teeth, and is made of materials such as ceramic or zirconium.

2- Crown: It is a cosmetic veneer that covers the entire tooth, and is used to improve the appearance of damaged, broken or decayed teeth.

3- Inlay and Onlay: It is a type of veneer used to correct damaged teeth due to decay or fractures, and is made of materials such as ceramic or gold.

4- Film (Lumineers): It is a very thin veneer placed on the teeth without the need for surface preparation, and is made of materials such as ceramic.

The types of cosmetic veneers differ in the materials used and in the way they are placed on the teeth, and a dentist should be consulted to determine the type that is most appropriate for each patient's condition individually.
