Although there are many benefits associated with porcelain veneers, it’s important for patients to understand any risks or downsides of the procedure that could affect them. Because a thin layer of the tooth’s enamel is removed before a veneer is placed, this is not considered to be a reversible procedure. Veneers can be replaced or adjusted, but the natural tooth enamel cannot grow back.
Also, sensitivity to hot or cold temperatures can temporarily develop and increase because of the enamel removal. This will typically go away with time, but it can be bothersome for patients who already experience sensitivity to temperature prior to placing the veneer. However, the more time that passes, the veneer can potentially reduce sensitivity by providing a durable layer of protection over the tooth.
