What is the gap between crown and gum?

The gap between the crown and gum, often referred to as the "gingival margin," is the space where the tooth crown meets the gum tissue. This area is crucial for oral health, as it can be a site for plaque accumulation, potentially leading to gum disease if not properly maintained. A healthy gingival margin should be tight against the tooth, with no visible gaps or spaces. Regular dental check-ups are essential to monitor this area and ensure any issues are addressed promptly.
