Sedation Dentistry

Sedation Dentistry is practiced by many Dentists. A dental visit is most of the time accompanied by anxiety! To relieve the anxiety, Dr. Shalini Thasma, a Plano sedation dentist, uses Nitrous Oxide at her office.Nitrous oxide also called as “laughing gas” is an anxiolytic and an mild analgesic agent. It cannot be used alone and is always used in combination with Oxygen.

The “laughing gas” is administered through a mask that is placed on the nose. The first gas that is administered is 100% oxygen for 3-5 minutes. The nitrous oxide is then started from a lower concentration and slowly increased until a desired effect is achieved, which usually ranges from 25-50%. The signs and symptoms of what the patient experiences will usually be lightheadedness, feeling of warmth, tingling sensation or numbness at finger tips and hands, feeling light or heavy etc. All these sensations are normal. If at any time during the procedure you do not feel comfortable please let your dentist know so that they can adjust the concentration of the gases.At the end of the sedation, Nitrous is completely turned off and you will be breathing on 100% oxygen for 3-5 minutes.
