Dental fillings are a fundamental restorative treatment used to repair teeth affected by cavities, minor fractures, or localized decay. When oral bacteria erode tooth enamel, they create hollow spaces that can lead to severe pain and further structural damage if left untreated. By carefully removing the decayed tissue and sealing the cavity with a durable filling material, this procedure effectively halts the progression of decay, protects the sensitive inner nerves, and restores the tooth’s natural strength and integrity.
