How long do natural teeth last

Natural teeth can last for decades when enamel, dentine, pulp, gums, and supporting bone remain healthy and are maintained.

Natural teeth do not have one fixed expiry date: their lifespan depends on enamel and dentine wear, decay, gum support, bite forces, injury, diet, dry mouth, and home care. A clinical examination separates these possibilities.

Teeth last when decay and gum inflammation are controlled, cracks are treated early, grinding is managed, fluoride toothpaste is used, and dental examinations identify changes before they spread. Arrange an examination if the problem persists or worsens.

Arrange dental care for persistent pain, a crack, looseness, swelling, bleeding gums, sensitivity that worsens, or a tooth that changes colour after injury. Do not wait if swelling affects swallowing or breathing.

Ask whether the tooth has decay, a crack, pulp inflammation, gum attachment loss, or bite trauma, and which examination or radiograph separates those possibilities. Ask what the examination shows and what alternatives are reasonable.
