The short answer
Decay below the gum line can destroy root surface or reach the pulp, and it usually needs dental treatment rather than home care. Root exposure from gum recession exposes less-mineralized cementum and dentine to plaque acids. Decay can also begin at a filling margin, crown edge, or hidden fracture.
How can gum recession expose a tooth root to decay?
Root exposure from gum recession exposes less-mineralized cementum and dentine to plaque acids. Decay can also begin at a filling margin, crown edge, or hidden fracture.
What can you do to protect a weakened root before review?
Clean gently with a soft brush and fluoride toothpaste, reduce frequent sugary or acidic exposures, and avoid hard foods on the weakened tooth. Do not pack the cavity with household materials.
