Gingival recession is the exposure of tooth root surface caused by the gum margin pulling back from its normal position near the crown - this calculator translates a measured recession depth into a standard severity category.
Severity Scale
| Recession Depth | Severity |
|---|---|
| 0mm | None detected |
| 1-2mm | Mild |
| 3-4mm | Moderate |
| 5mm+ | Severe |
Example
Recession depth of 3mm with 4mm clinical attachment loss:
3mm - Moderate recession
Common Causes
Gingival recession often results from aggressive brushing technique (using a hard-bristled brush with excessive force), periodontal (gum) disease, thin gum tissue biotype, or grinding/clenching habits. Clinical attachment loss is measured separately by a dental professional and combines probing depth with recession, making it the more clinically significant number for tracking periodontal disease progression over time. This tool is educational only and does not replace an in-person periodontal evaluation.
