Local Anesthesia
Local anesthetic 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:

1)	Some patients will interpret pushing pressure and vibration as pain. Local anesthetic will not block these sensations.
2)	Local anesthetic does not work completely when inflammation and / or infection is present. A tooth that is painful tender or infected may not get numb and the patient will subsequently feel pain regardless of how much local anesthetic is used.
3)	Each patient will respond differently to medications. Adverse reaction to a medication is always possible, as is allergy. No medication is 100% safe; because of this, our office maintains current equipment and training for use in case problems arise.

Nitrous Oxide Sedation with Local Anesthesia
Nitrous oxide (laughing gas) is administered along with oxygen by nasal hood to the nose. Nitrous oxide will reduce anxiety associated with oral surgical 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:

1)	All limitations of local anesthesia apply.
2)	Patients must breathe through their nose for the nitrous to work.. Patients who breathe through their mouth will not gain any benefit from the administration of nitrous oxide gas.
3)	Nitrous oxide will not prevent the patient from feeling pain if local anesthesia is inadequate.
4)	Patients remain awake and alert during oral surgical procedures.
5)	Patients are strongly encouraged to not eat before their appointment to reduce the chance of nausea and vomiting.
6)	Each patient will respond differently to medications. Adverse reaction to a medication is always possible, as is allergy. No medication is 100% safe; because of this, our office maintains current equipment and training for use in case problems arise.

Oral Sedation with Local Anesthesia
Oral sedative medication 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 oral surgical treatment but they will tend to ignore non painful stimuli such as pressure and noise.

Limitations of oral sedation:

1)	All limitations of local anesthesia apply.
2)	Patients should not eat for 6 hours prior to their dental appointment; patients may drink clear fluids up to 2 hours prior to their dental appointment. Patients who do not comply with this request will likely not get the maximum benefit from the medication due to poor or delayed uptake into the body.
3)	Patients must have an escort / driver who will drive the patient to and from the dental appointment.
4)	Patients may not drive, operate dangerous tools or equipment or make important decisions for 12 hours after taking this medication.
5)	Patients will still feel and react to pain if local anesthesia is inadequate.
6)	Patients will remain awake during treatment, although they may have some degree of amnesia (memory loss).
7)	Each patient will respond differently to medications. Adverse reaction to a medication is always possible, as is allergy. No medication is 100% safe; because of this, our office maintains current equipment and training for use if problems arise.

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:

1)	All limitations of local anesthesia, nitrous oxide and oral sedation apply.
2)	Each patient will respond differently to medications. Adverse reaction to a medication is always possible, as is allergy. No medication is 100% safe; because of this, our office maintains current equipment and training for use if problems arise.

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:

1)	Patients who have significant anxiety associated with oral surgery.
2)	Patients who present for difficult or extensive surgical procedures.
3)	Patients who present with painful or infected teeth.
4)	Patients who are unable to open their mouths.
5)	Patients who have a history of high blood pressure or heart disease; these patients may tolerate oral surgery procedures better if they are lightly sedated to reduce dangerous fluctuations in blood pressure readings.

Limitations of treatment:

1)	Patients must not eat for 8 hours prior to their dental appointment; patients may drink clear fluids up to 2 hours prior to their oral surgery appointment. Unless otherwise directed by the surgeon, the patient should take medications with a small amount of water at their usual time. Patients may not take food with medication under any circumstance.
2)	Patients must have an escort / driver who will drive the patient from the dental appointment.
3)	Patients may not drive, operate dangerous tools or equipment or make important decisions for 12 hours after taking this medication.
4)	Each patient will respond differently to medications. Adverse reaction to a medication is always possible, as is allergy. No medication is 100% safe; because of this, our office maintains current equipment and training for use if problems arise.
