Local anesthesia
Local anesthetic (modern day novacaine) is administered by injection to numb surgical areas. Topical anesthetic get is applied prior to injection. Under normal circumstances, once an area is numb, surgical pain is not felt. Patients will feel pushing, pressure and vibration; patients will also be aware of surgical noise.
Limitations of local anesthesia
Nitrous oxide sedation with local anesthesia
Nitrous oxide (laughing gas) is administered by nasal hood to the nose. Nitrous oxide will reduce anxiety associated with dental procedures. Nitrous oxide works particularly well with children. Patients receiving nitrous oxide will remain awake and alert, but will tend to ignore non painful stimuli.
Limitations of nitrous oxide
Oral sedation with local anesthesia
Oral sedative medication (modern day valium) is taken by the patient the night before and one hour before the planned dental appointment. This medication will reduce anxiety associated with dental treatment and will provide very light conscious sedation; some amnesia (memory loss) may occur. Patients remain awake during their dental treatment but they will tend to ignore non painful stimuli
Limitations of Oral sedation
Oral sedation, nitrous oxide and local anesthesia
These three anesthetic modalities may be used to together to maximize anti-anxiety and sedative effects.
Limitations of treatment
IV sedation and General anesthesia
A combination of medications are administered to the patient through an intravenous line. Patients may dictate whether they wish to be lightly sedated (responsive to stimuli) or asleep (not responsive to stimuli). Patients are not intubated (as they are in the operating room setting) and will continue to breathe on their own. Patients will not feel pain, and it is unlikely that they will remember much of the surgical procedure. This form of sedation allows for the careful titration of medication to maximize sedation while minimizing the chance for prolonged oversedation.
The administration of sedative medications through an intravenous line might be indicated for the following patients:

Understanding Dental Anesthesia:
What Every Patient Should Know
(from the ADA)
Providing you with high-quality, appropriate care and making your dental visit as comfortable as possible are top priorities for the 143,000 members of the American Dental Association (ADA). Advances in dental techniques and medications can greatly reduce, even eliminate, discomfort during dental treatment, and your dentist and the ADA want you to know about them. Here are some of the options available to help alleviate anxiety or pain that may be associated with dental care:
Local Anesthesia
Injectable local anesthetics, such as Novacaine, prevent pain in a specific area of your mouth during treatment by blocking the nerves that sense or transmit pain and numbing mouth tissues. They cause the temporary numbness often referred to as a "fat lip" feeling. Injectable anesthetics may be used in such procedures as filling cavities, preparing teeth for crowns or treating gum disease.
Sedation and General Anesthesia
Anti-anxiety agents, such as nitrous oxide, or sedatives may help you relax during dental visits and often may be used along with local anesthetics. Dentists also can use these agents to induce "conscious sedation," in which the patient achieves a relaxed state during treatment but can respond to speech or touch. Sedatives can be administered before, during or after dental procedures by mouth, inhalation or injection.
More complex treatments may require drugs that can induce "deep sedation," causing a loss of feeling and reducing consciousness in order to relieve both pain and anxiety. On occasion, patients undergo "general anesthesia," in which drugs cause a temporary loss of consciousness. Deep sedation and general anesthesia may be recommended in certain procedures for children or others who have severe anxiety or who have difficulty controlling their movements.
The ADA provides guidelines to help dentists administer pain controllers in the safest manner possible. Dentists use the pain and anxiety control techniques mentioned above to treat tens of millions of patients safely every year. Even so, taking any medication involves a certain amount of risk. That's why the ADA urges you to take an active role in your oral health care. This includes knowing your health status and telling your dentist about any illnesses or health conditions, whether you are taking any medications (prescription or non-prescription), and whether you've ever had any problems such as allergic reactions to any medications. It also includes understanding the risks and benefits involved in dental treatment, so that you and your dentist can make the best decisions about the treatment that is right for you.
Understanding the range of choices that are available to relieve anxiety and discomfort makes you a well-informed dental consumer. If you have questions or concerns about your oral health care, don't hesitate to talk to your dentist. If you still have concerns, consider getting a second opinion. Working together, you and your dentist can choose the appropriate steps to make your dental visit as safe and comfortable as possible, and to help you keep a healthy smile.
