Veneers are routinely used to fix:
Teeth that are discolored — either because of root canal treatment; stains from tetracycline or other drugs, excessive fluoride or other causes; or the presence of large resin fillings that have discolored the tooth
Teeth that are worn down
Teeth that are chipped or broken
Teeth that are misaligned, uneven, or irregularly shaped (for example, have craters or bulges in them)
Teeth with gaps between them (to close the space between these teeth)
