Teeth Whitening Your teeth will darken over time. Changes in the colour of your teeth can be caused by such factors as food and beverages consumed (coffee, tea and soft drinks). Other known factors for discolouration may include childhood medications or illnesses, tobacco use, or improper oral hygiene. Our goal is to meet the needs of every patient, and every patient’s needs are different, so we can provide a variety of options for whitening your smile. Composite (white) fillings: These are resin / composite bonded fillings, which can be matched to the colour of the tooth. These fillings don't contain any toxic substances and they can be placed on both front and back teeth. We use only the best white filling materials so that not only do they look great but they last a long time as well. White fillings have glue like properties which means they bond the tooth together and in some case can be used to strengthen the tooth. It is necessary to remove all the decay and clean the tooth before placing the filling. Once the material has been progressively placed in the tooth a special curing light is used, which immediately sets the filling. Fissure Sealants Fissure sealant is a special varnish used to prevent cavities from developing in the pits and fissures of teeth.
