Composites may not work if a cavity is too large or an area is
subject to heavy chewing. Your dentist knows when composite resin is
most appropriate as a restoration material. For many patients, white
fillings, or composites, make a healthy smile a natural looking
smile. When simple tooth filling is not appropriate inlays or onlays
can be choosen.
Inlays are tooth-colored restorations placed on the chewing surfaces
of your back teeth. They can be used instead or in place of silver
Onlays can be used many times in place of crowns, allowing
preservation of more tooth structure.
Depending on their size and location, fillings can reduce the
strength of a tooth by up to 50%. Inlays and onlays, on the other
hand, can actually increase the strength of the tooth by up to 75%.
Inlays and onlays are fabricated outside of the mouth and therefore
are capable of being made much stronger than typical fillings.
Inlays and onlays are especially suitable for the chewing surfaces
of back teeth. They can be the same color as your teeth.
