Dental cavity filling, a cornerstone of restorative dentistry, is a procedure designed to repair and restore teeth that have been affected by decay or minor damage. Cavities, also known as dental caries, are areas of the tooth's enamel that have been weakened and eroded by harmful bacteria and acids. Left untreated, cavities can lead to further tooth damage, pain, and even infection. Dental cavity filling is a crucial treatment that not only alleviates discomfort but also preserves the tooth's function and aesthetic appeal.
