Dentists always make their best effort to save a tooth instead of opting for an extraction immediately.
In some cases, untreated cavities can cause severe tooth decay and it becomes impossible to consider restorative procedures. This is when a process called ‘crown lengthening’ comes into the picture. Crown lengthening begins a lowered gum line and consequently a longer crown.
Crown lengthening works by recontouring the gum line to increase the crown of the decayed tooth. Dentists use this surgical process when there is a lack of tooth structure to support a crown. In cases where a tooth has fragmented below the gum line, dentists use crown lengthening to expose the broken part of the tooth for increased tooth structure.
