Sedation or sleep dentistry refers to the use of sedatives to calm and relax a patient prior to and during a dental appointment. These sedatives exert their action by depressing the central nervous system, specifically those areas concerned with conscious awareness. There are different degrees of central nervous system depression, each corresponding to a level of relaxation which ranges from minimal, moderate, to deep sedation. In general, minimal sedation refers to a patient who has reduced anxiety but readily responds to verbal or physical stimulation. With moderate sedation, the patient is even more relaxed and will respond to purposeful stimulation. In deep sedation, the patient may not exhibit any signs of consciousness and therefore be unresponsive to stimulation. We focus on deep IV Sedation at The Tooth Corner. Deep sedation is great for young children or adults with anxiety. Sedation is also covered by Healthy Smiles Ontario (HSO).
