Ask your Tarzana dentist, Afsoon Gerayli, DDS, how long you can expect your porcelain veneers to last. Research shows that with proper installation and fine quality materials you can expect most porcelain veneers to last 10-20 years or longer if they are properly maintained. 

The primary reasons your veneers may fail could be chips or cracks, structural complications or the veneer falls off. As few as 5% of veneers may fail within 5 years.
Comparing this with dental crowns, those may need to be replaced within 7-10 years. Compared to composite veneers, 75% may need to be replaced within 2 years but 94% of porcelain veneers will still be functioning at that time.

Research indicates that the level of your dentist's experience and the proper use of all standard procedures will influence how long the veneers will last.(1) The longest lasting veneers are those which are bonded directly to tooth enamel, rather than dentin. 

Proper care includes good oral hygiene, brushing, flossing and prevention of tooth decay. Gum recession can also be problematic. 

Grinding your teeth or using them to chew on hard objects, like fingernails or engaging in forceful athletics. Use athletic mouth guards for protection. Staining from smoking, coffee or wine can reduce the effectiveness of porcelain veneers. Also be aware that extreme temperatures can cause expansion and contraction of the porcelain laminate and thus reduce their longevity. 

Your Reseda dentist is prepared to help you decide if porcelain veneers are the best choice for the care of your teeth. Sometimes a crown is a better answer if too much dentin will be involved with the bonding. Call for a consulting appointment if you are uncertain.
