A Hollywood smile is not only whiter teeth. Tooth length, gum display and harmony with the side teeth are planned together. Suitable candidates have decay and active gum disease under control, and want a natural result.
Heavy grinding, a serious bite problem or weak bone support is treated first. Otherwise a veneer can chip or gums can recede.
Timing depends on how many veneers are needed. Most smile designs finish in 5–7 days; implant plans may need a second visit.
