Dental sedation refers to medically controlled techniques that help patients remain calm and comfortable during dental procedures. These methods are especially valuable for:
Patients with dental phobia or anxiety
Those with sensitive gag reflexes
Individuals undergoing lengthy procedures
Patients with special needs or mobility issues
Levels of Sedation Available
Minimal Sedation (Anxiolysis)
Patient remains fully awake but relaxed
Uses nitrous oxide or mild oral medications
Quick recovery – can drive home afterward
Moderate Sedation (“Twilight Sedation”)
Slurred speech but responsive to verbal cues
Typically uses IV medications
Amnesia effect for the procedure
Requires escort home
Deep Sedation
Near-unconscious state but breathing independently
Used for complex oral surgeries
Administered by anesthesiologists in dental settings
General Anesthesia
Complete unconsciousness
Reserved for major maxillofacial procedures
Requires hospital-like monitoring
Types of Dental Sedation
Nitrous Oxide (Laughing Gas)
Administration: Inhaled through nasal mask
Onset: 3-5 minutes
Duration: Adjustable during procedure
Recovery: 5-10 minutes after stopping
Best For: Mild anxiety, children, short procedures
Oral Sedation
Medications: Typically benzodiazepines (e.g., triazolam)
Protocol: Taken 1 hour before appointment
Effects: Significant relaxation with memory impairment
Common Uses: Wisdom teeth removal, implant surgery
Local Anesthesia Combinations
Often paired with sedation for pain-free experience
Includes lidocaine, articaine, or bupivacaine injections
