Made of composites or porcelain, dental veneers cover and protect a damaged tooth, while providing an aesthetically-pleasing exterior. They are typically used by your dentist to protect you from worn tooth enamel, uneven tooth alignment, abnormal spacing, chips and cracks. Traditional porcelain veneers can last up to 15 years. Composite veneers usually must be replaced a little earlier. The process can be very important to the health of your teeth and your dentist can provide details about it. The satisfactory rate among dental patients receiving veneers is typically very high.
