Sedation Dentistry

Complete guide to this dental treatment

Sedation dentistry uses medication to help patients relax during dental procedures. It's often called "sleep dentistry," though most patients remain awake except under general anesthesia. Sedation benefits anxious patients, those with low pain threshold, sensitive gag reflex, or needing extensive dental work.

Levels of Sedation

Minimal Sedation (Anxiolysis)

You're relaxed but fully awake and able to respond normally. You'll remember the procedure.

Moderate Sedation (Conscious Sedation)

You may slur words and not remember much of the procedure. You can still respond to instructions and remain conscious.

Deep Sedation

You're on the edge of consciousness but can be awakened. You won't remember the procedure.

General Anesthesia

You're completely unconscious and cannot be awakened until the effects wear off or are reversed.

Types of Sedation

Inhaled through a mask placed over your nose, causing relaxation and mild euphoria.

Oral Sedation

IV Sedation (Intravenous Sedation)

When used:

  • Extremely anxious patients who can't be treated otherwise

Who Benefits from Sedation Dentistry?

  • Dental phobia: Severe anxiety or fear of dentists

Safety Considerations

Before Sedation

  • Disclose complete medical history
  • List all medications and supplements
  • Inform dentist of allergies
  • Follow fasting instructions if given
  • Arrange transportation
  • Wear comfortable clothing

During Procedure

Your vital signs (blood pressure, heart rate, oxygen levels) are continuously monitored. A trained professional administers and oversees sedation throughout treatment.

After Sedation

  • Have someone drive you home
  • Rest for remainder of day
  • Follow post-treatment instructions
  • Don't drive, operate machinery, or make important decisions for 24 hours

  • Start with light foods if hungry

Who Shouldn't Have Sedation?

Certain conditions may preclude sedation or require special precautions:

  • Pregnancy (especially first trimester)
  • Certain heart conditions
  • Respiratory problems (for nitrous oxide)
  • Sleep apnea (may require special monitoring)
  • Certain medication interactions
  • Allergy to sedative medications
  • Glaucoma (for certain sedatives)

Always consult your dentist and doctor about your specific situation.

Cost and Insurance

Sedation is often considered optional and may not be covered by NHS or insurance unless medically necessary. Costs vary widely based on:

  • Type of sedation
  • Procedure length

Many private practices offer sedation as an additional service with payment plans available.
