This hyper-realistic 3D dental illustration shows the clinical steps in a crown lengthening procedure. A periodontal probe measures the gingival sulcus and biological width, while a rotary instrument reshapes the gum tissue to expose more of the tooth’s clinical crown. This procedure is typically done when there isn’t enough visible tooth structure to support a dental crown or restoration. Crown lengthening may also be indicated in cases of gummy smile or subgingival decay.
