Composite bonding is a generic term encompassing many types of bonding including space closure, edge bonding to lengthen teeth, closure of black triangles and treatment of surface irregularities. A composite veneer covers the front surface of the tooth often performed as part of a full smile makeover totally changing ones appearance and smile.
The longevity of composite bonding procedures can vary massively depending on many factors including the skill of the treating dentist, toughness and type of the composite used, gum health of the patient during application and habits such as teeth grinding and clenching. These factors need to be taken into account when discussing longevity with patients.
Composite bonding cases can be very successful long term however each case needs to be managed on its own merit and the treatment needs to be tailored to the individual to ensure any potential issues are addressed before the procedure.
Unfortunately not every individual is suitable for composite bonding and issues usually arise when best guidance and a clear scientific protocol has not been followed. Excellent gum health is of paramount importance before any bonding as blood contamination can lead to leakage and staining. This is why we always make sure the client has good oral hygiene on a consistent basis before starting.
Another major reason for failure of composite bonding is a bite issue namely clenching and /or grinding. These types of clients often present with existing wear of the teeth and are high risk of fracture and failure. Bite issues can be treated first followed by safe application of composite which can massively reduce failure. A soft mouthguard can also be provided for day/night time wear to protect the composites during grinding episodes.
Composites can wear down over time and the surface can lose its shine as it is not as strong as a porcelain veneer and does not have a glazed surface applied in a furnace. A porcelain veneer case performed correctly will still look good in 10 years however a composite veneer case will usually look very tired at 10 years even with regular polishing.
There are no specific timeframes for longevity of composite bonding as each case is different however if the case is performed well the procedure will be very cost effective for the client and a great first step into the world of cosmetic dentistry.
