Is There Any Connection Between Porcelain Veneers and Bad Breath?

The odds are that porcelain veneers are not the cause of your bad breath.  When performed correctly, porcelain veneers should collect minimal bacteria.  Bad breath is the accumulation of bacteria in the mouth over a period of time that is not removed.  Make sure to brush several times a day preferably with an ultrasonic toothbrush and floss at least once a day to break up the bacteria between the teeth.  Now if there are open margins in your veneers or open contacts where food is accumulating, then this would cause bad breath.  If not, there is another issue causing this that needs to be determined by your dentist. 

Porcelain veneers shouldn't lead to bad breath.  Bad breath is usually caused by bacteria in the mouth that is not cleaned away in a timely manner.  When done well, porcelain veneer are smooth and seamless.  There should be no little nooks or crannies for bacteria to live, therefore no bad breath.

Treat your veneers as you should treat your teeth.  Floss, and brush at the minimum.  Rinse well and you should be fine.

Veneers are generally not responsible for bad breath.  Mouth odor comes from the presence of gum disease, poor oral hygiene, digestive system issues and tooth decay.  Only when veneers are designed or placed poorly, having open margins where food and bacteria can collect does mouth odor emanate from the veneers.

It is important to practice good oral hygiene habits at home daily as well as periodic examinations and maintenance with the dental staff as indicated by the dentist and hygienist.  When mouth odor persists, a dental visit is a must.  These odors can also be indicators of serious medical problems like Diabetes and other systemic diseases.
