Porcelain veneers will last the longest of any material and will not discolour or stain. Done correctly they can often involve little or no tooth preparation similar to stated advantages of composite veneer. They can be very white but this is often quite artificial. They can also be fabricated to look beautiful and natural and so do not always need to look artificial.
Natural-looking Teeth: Like tooth enamel, porcelain is white and translucent as well. This means light reflects off porcelain just as it does with tooth enamel; reflecting off the layer that is underneath them. The layer under enamel is the yellow dentin and the layer under porcelain is the dental adhesive that bonds it to the teeth. Therefore, porcelain veneers look natural and make your teeth look naturally white.
Stain Resistant: Stains roll or wipe off porcelain just as they do with glass, thanks to porcelain being ceramic. Thus, porcelain veneers are made not just to whiten your teeth initially but to keep them white, even if you often consume stain-producing foods and beverages.
Longevity and Durability: Porcelain veneers are strong and can last up to 10-20 years as long as they are cared for well.
Instant Result: The result in case of this medical beauty solution is instant. You don’t have to wait months or go through multiple appointments for the results to start to show.
However well they are done they will have a lifespan and you may need replacement veneers. As long as they are bonded to enamel (the strongest and longest lasting bond) this will be some 10-15 years. Bonding to enamel is achieved via additional wax-up and use of a trial smile to ensure that this additive wax-up is not too bulky. If it is, then some degree of orthodontic pre-alignment is most sensible.
Possibility of Damage: It is true that porcelain veneers can last for years and remain intact as well but there is always the possibility of it breaking, coming off, or chipping. If it comes off, your dentist will more than likely reattach it, but in case it breaks, you will have to get the process done all over again. Keeping them in good care and not using your teeth for things like opening product packaging will generally keep your veneer safe.
Irreversible Process: Once you get porcelain veneers, you cannot change your mind. A part of your enamel is removed to bond the veneer that entirely changes the look of your teeth. Without the veneer, your teeth can look unaesthetic.
Higher Tooth Sensitivity: If you hate how your teeth react to hot or cold foods and beverages, rethink your decision to get porcelain veneers. They can increase your tooth sensitivity due to the enamel that is removed in the process. However, the increased sensitivity might not occur or may just be temporary.
