Hall Technique

Minimally Invasive SMART Hall Crown Technique

This revolutionary dental treatment is quick, painless, simple, and effective, with high levels of evidence. Most importantly, it can help young or fearful patients, (such as children and special needs patients) avoid shots, drills, sedation and/or general anesthesia (GA) for dental work to treat their cavities. This treatment is standard of care in the UK, with its origins in Scotland more than a decade ago. The Hall technique is not well known or widely practiced in the US, though we hope that is changing as awareness and adoption of minimally invasive treatment options increase.

What is The Hall Technique?

Hall Technique (HT) is a minimally invasive restorative option for primary teeth with severe decay and/or hypomineralization without numbing (shots), tooth preparation (drilling), or sedation (general anesthesia/IV deep sedation). HT is an evidence based procedure with 5 randomized control trials, with clinical efficacy equivalent to the conventional surgical approach to stainless steel crown (SSC) placement. It originated in Scotland in the 1990’s where general practitioner, Dr. Norna Hall, accidentally discovered that when she sealed her pediatric patient’s carious lesions within a glass ionomer cement under a SSC, the lesions became arrested (inactive) once starved of the carbohydrate substrate necessary to get worse/deeper. Sealing the lesions allows the vital pulp to lay down reparative dentin and retreat/wall itself off from the carious lesion. The procedure is well tolerated by most pediatric patients and is a welcome alternative to the more invasive surgical approach.


  • Decayed primary teeth
  • Asymptomatic or reversible pulpitis
  • Clear band of dentin between the carious lesion and the pulp on a radiograph
  • Newly erupted first permanent molars with severe molar incisor hypomineralization (MIH)


  • Decay extends into the nerve
  • Pain or infection (Irreversible pulpitis)
  • Unrestorable teeth
  • Patients where the airways cannot be protected due to very poor cooperation (will not open mouth, cannot stay still for placement of the crown, will not tolerate anything being placed into the mouth like a mirror, gauze, etc.)
