With sedation dentistry there’s no need to be anxious about your dental procedure.

Those who experience a low level of fear or anxiety associated with seeing the dentist, but still need help calming worries may benefit from nitrous oxide. Commonly called “laughing gas” or “happy gas,” nitrous oxide will help alleviate negative thoughts and improve your dental experience.

Nitrous sedation is safe for all age groups. It is eliminated from your body very quickly and patients feel normal within 10 minutes of completion of the procedure.

Contraindications of nitrous sedation include:

  • Breathing problems like sinusitis, cold, influenza and allergies
  • Lung conditions like bronchitis and emphysema
  • First trimester of pregnancy
  • Eye or ear surgery
  • Cancer treatment with bleomycin sulphate

Oral Sedation

Oral sedation is the easiest way of administering sedation by simply swallowing a pill before the appointment. There is no need to breathe through a mask-like nitrous sedation.

Patients are required to be at our office one hour before your appointment to take the oral sedation pill. You should not eat or drink six hours before the procedure and it is absolutely essential that you have someone to take you home after the procedure.

Contraindications of oral sedation include:

  • Pregnancy
  • Nursing mothers
  • Glaucoma or myasthenia gravis
  • Allergy to benzodiazepines
  • Severe medical conditions
  • Severe respiratory problems like asthma or emphysema
  • Psychosis
  • Taking a medication called an MAO inhibitor
