UV inspection is a useful tool in dentistry as enamel, dentin and caries have different fluorescent properties when illuminated by UV light. Dentin is three times more fluorescent than enamel because of its greater amount of organic material.
Depending on the type of porcelain that the veneers are made out of, it can glow in blacklight. Not all porcelains will glow in the dark but most of the ones that are specifically used for veneers will most likely glow in blacklight.

Artificial teeth, such as porcelain crowns, veneers, or dentures don't contain phosphors and will not glow under blacklight.
White fillings can also be called dental composite and they are the tooth-coloured resins used to fill cavities. This composite resin is made of a blend of plastics and fillers such as silica and dimethylglyoxime which bond with the tooth's surface.

Blue light itself cannot whiten the teeth. Instead, blue light is used to activate a chemical reaction.

Body Fluids Fluoresce Under Black Light
Forensic scientists use ultraviolet lights at crime scenes to find blood, urine, or sem*n.
Black dots in sem*n is likely due to hematospermia—or blood in the sem*n. Blood can turn dark as it ages, so black specks in sem*n may indicate old bleeding. Possible causes can include infection or inflammation in a man's reproductive tract. See your doctor for any changes in sem*n that persist.

Porcelain can be investigated using a black light. Hard paste porcelain will fluoresce a deep blue, while soft past procelain will fluoresce white. One can easily determine repairs jobs, as modern glue and chemicals glow under a black light, as well as later additions of embellishment to a piece, cracks and seams.
A phosphor emits visible light in response to some sort of radiation. It converts the energy in the UV radiation from a black light into visible light. Artificial teeth, such as porcelain crowns, veneers, or dentures don't contain phosphors and will not glow under blacklight.
Composite resin is a mixture of plastic and glass or quartz. It's applied in layers which are cured using a UV light. They're used for filling cavities and repairing chipped or cracked teeth.

What color is cubic zirconia under UV light?
Fluorescence occurs when a gem material is illuminated by radiation of shorter wavelengths with higher energy. A bag of cubic zirconia under LWUV with areas of blue fluorescence that highlights the presence of diamonds. The visible light emitted stops when the source of illumination is turned off.
vs. Some diamonds show orange fluorescence under long wave and a weaker orange under short wave. Cubic Zirconia (CZ) often shows orange fluorescence but in REVERSE ORDER.
