Fillings
Fillings are the first line of defense against loss of tooth structure. Loss of structure can be caused by decay (cavities), physical trauma (accidentally biting into something that chips teeth), and/or wear (grinding/brushing too hard with a hard bristle brush). Decay is caused by a type of bacteria strep mutans that digests sugars and carbohydrates to form lactic acid, which can begin to dissolve tooth structure over time if left unchecked. Fillings can also be used cosmetically to improve tooth shade as well as fill in gaps between teeth.
Though they are the first line of defense, fillings have their limits. For decay and damage caught early, fillings of small to medium size are expected to last a very long time. For replacing very large areas of missing tooth structure, the longevity of the restoration varies depending on which teeth are involved, chewing habits, and size of filling. A tooth that has had multiple fillings done or a particularly deep/large filling may need a crown and/or root canal in the future.
Composite Resin
Composite resin fillings are tooth-colored, non-metal fillings that can be blended and polished to conform with the contour and appearance of natural teeth. We are selective on the quality of composite we use and make sure we carefully select the appropriate shade for each filling. We have the option to use a composite that automatically blends in with the surrounding tooth structure, or specific shades where necessary, such as brightening up front teeth.
Amalgam
Amalgam fillings are silver fillings made up of an alloy of metals. These are the historically traditional way of fillings, and are just as durable as composite fillings. The main disadvantage is their appearance, dark in color and unsuitable for front teeth. We typically do not use amalgam fillings except in very specific deep cavities near the gums where there is too much moisture.
