Several methods of anesthesia are available. The method of anesthesia that is chosen for or by a patient depends upon the nature of the surgical procedure and the patient’s level of apprehension.
Local Anesthetic is always administered using a needle. There are different types of local anesthetics and the type you will be receiving is based on a number of factors; medical history, sensitivity to previously administered local anesthetics. The anesthetic effect typically last about 2-4 hours.
Anesthetic Gel is a type of anesthetic, similar to local anesthetic that is placed via a cannula vs. a needle into the gum tissue to numb the area. This is not profound anesthesia, like local anesthetic, but in some treatments, like scaling and root planning, it is feasible. The anesthetic effect typically lasts no more than 30 minutes.
Nitrous Oxide is a sweet smelling, non irritating, colorless gas which you can breathe. Nitrous Oxide has been the primary means of sedation in dentistry for many years. Nitrous oxide is safe; the patient receives 50-70% oxygen with no less than 30% nitrous oxide. Patients are able to breathe on their own and remain in control of all bodily functions. The patient may experience mild amnesia and may fall asleep not remembering all of what happened during their appointment.
There are many advantages to using Nitrous Oxide
- The depth of sedation can be altered at any time to increase or decrease sedation.
- There is no after effect such as a “hangover”.
- Inhalation sedation is safe with no side effects on your heart and lungs, etc.
- Inhalation sedation is very effective in minimizing gagging.
- It works rapidly as it reaches the brain within 20 seconds. In as few as 2-3 minutes its relaxation and pain killing properties develop.
Reasons to Not use Nitrous Oxide
Though there are no major contraindications to using nitrous oxide, you may not want to use it if you have emphysema, exotic chest problems, M.S., a cold or other difficulties with breathing. You may want to ask your dentist for a “5 minute trial” to see how you feel with this type of sedation method before proceeding.
