How do your teeth not rot under veneers?


Editorial team Published on

Teeth do not rot under veneers because a strong dental cement creates an airtight seal that blocks bacteria, acids, and food particles from reaching the covered tooth structure.

Why Teeth Stay Protected

  • Airtight Bonding: Dentists use a specialized adhesive cement hardened with a curing light to tightly glue the porcelain or composite shell to the front of the tooth.
  • Enamel Sealing: This chemical bond closes any microscopic gaps where microorganisms could otherwise enter and trigger decay.
  • Smooth Margins: When properly fitted by a professional, the edges of the veneer sit flush against the natural tooth, leaving no room for plaque to slip underneath.

When Can Decay Still Happen?

While the sealed front is protected, teeth can still develop problems if the seal fails or hygiene is neglected:

  • Loose or Cracks: If a veneer chips, cracks, or lifts at the edge, a tiny gap forms that can trap saliva, bacteria, and sugars.
  • Gumline Exposure: Veneers do not cover the entire back or sides of a tooth. Plaque can still build up around the gumline if you do not brush and floss daily.
