Veneers and hair transplant contraindications

Patients often ask: “Can I get veneers?” or “Am I suitable for a hair transplant?” But not everyone knows there are specific cases when these procedures are impossible or unsafe.

The short answer: veneers cannot be placed when there are active diseases of the teeth and gums, and a hair transplant cannot be performed with serious chronic diseases. Read on for details.

Contraindications to Veneers

Veneers are an aesthetic restoration, but they are not suitable for everyone. There are absolute and relative contraindications.

Absolute contraindications

  • Active periodontitis or periodontal disease — inflammation of the tissues surrounding the tooth.
  • Pronounced malocclusion — edge-to-edge, underbite, deep bite, or open bite.
  • Uncontrolled bruxism — teeth grinding that destroys the restorations.
  • Tooth more than 50% destroyed — a crown, not a veneer, is needed.
  • Missing chewing teeth — the load on the front teeth is too high.
  • Allergy to materials — a rare but possible reaction to ceramic or composite.

Relative contraindications

  • Untreated tooth decay — the teeth must be treated first.
  • Gum disease — gingivitis, bleeding, or inflammation.
  • Thin enamel — less than 0.5 mm in the preparation area.
  • Pregnancy and breastfeeding — hormonal changes affect the gums.
  • Poor oral hygiene — risk of inflammation and veneer detachment.
  • Habits such as biting nails or seeds or opening bottles with the teeth — risk of chips.

Contraindications to Hair Transplantation

A hair transplant is a surgical procedure, so medical restrictions apply.

Absolute contraindications

  • Uncontrolled chronic diseases — diabetes, hypertension, or heart disease.
  • Oncological diseases — active cancer or recent chemotherapy.
  • Blood clotting disorders — risk of bleeding and complications.
  • Active scalp diseases — psoriasis, dermatitis, or infections.
  • Epilepsy — risk of seizures during the procedure.
  • Mental disorders — unrealistic expectations or an unstable condition.

Relative contraindications

  • Age under 25 — hair loss has not yet stabilized.
  • Very weak donor area — insufficient material for transplantation.
  • Alopecia — autoimmune hair loss.
  • Smoking — impairs healing and follicle survival.
  • Taking anticoagulants — must be discussed with a doctor.
