Dental fillings are the most common restorative procedure. After decay is removed from a tooth, a filling is used to give strength back to the tooth.
Silver amalgam fillings have been used in dentistry for many decades, and although they are still regarded as safe and appropriate they are often the underlying cause of unexplained broken teeth. Metal fillings expand and contract with temperature changes in the mouth, and over time this process causes movement of the tooth and eventually tiny cracks form. The weakened tooth unexpectedly breaks one day- sometimes while eating something innocent!
At Lakeshore Dental, Dr. Izabela Olczyk prefers to use white composite fillings which do not expand and contract like silver amalgam fillings. White fillings are made of a strong composite resin that is matched to the surrounding tooth colour. In the past, white fillings were placed only on front teeth, but recently a stronger more durable material has been developed that can withstand the chewing pressure of back teeth.
White fillings are most commonly used for:
- Cosmetic reasons, they look more natural
- Patients who are concerned about mercury contamination
- Patients with sensitivity to heat or cold
