For many years now, silver fillings have been used to restore decayed teeth. Over time, teeth tend to crack as a result of the expansion and contraction of the silver when exposed to the hot and cold liquids we drink. These fractures start off small and are difficult to detect. Eventually the fractures go deeper and cause temperature and pressure sensitivity when biting, or cause large portions of the tooth break off. In many instances a root canal procedure becomes necessary to resolve the symptoms. Additionally, it becomes more difficult and costly to restore the tooth.
A more preventative approach is to replace silver fillings before cracking occurs, with new composite (tooth colored) fillings or porcelain-bonded restorations. This usually prevents further deterioration of the tooth. Dental composites chemically adhere to the tooth and binds it together restoring strength and integrity. Composites are typically as strong as the original tooth and can be formulated to match your tooth color. You’ll be pleased with how natural they feel alongside your original teeth.
A crown, or “cap,” is generally required when a significant portion of a tooth has been destroyed by decay, fractures or excessive wear. Crowns can also be used for cosmetic purposes to improve color and shape. Unsightly old-style porcelain metal crowns have been replaced with today’s all-porcelain crowns, which look nearly identical to natural teeth.
