Cosmetic dentistry:

Is generally used to refer to any dental work that improves the appearance (though not necessarily the function) of a person's teeth, gums, and/or bite.

Examples:

Teeth whitening, crowns and veneers, bridges, dental implants, dentures, white fillings, and bite reclamation (raising the vertical dimension in a collapsed bite).  Patients who have had years of excessive wear to their teeth due to grinding or acid reflux can alter their vertical bite dimension. This gives them a closed or shorter look to their face and smile. By opening up their bite, a qualified professional can reclaim their vertical dimension and sometimes even remove unwanted wrinkles as well (see also the Crowns, Bridge, and Denture sections on this site).
