There is no single best option for everyone. The right choice depends on how difficult the extraction is expected to be, how many teeth are being removed, your level of anxiety, your medical history and where the procedure needs to take place.
Local anaesthetic is often sufficient for straightforward treatment and for patients who are comfortable remaining awake. IV or twilight sedation can make you feel sleepy, calm and less aware of the procedure. General anaesthetic places you into a carefully controlled state of unconsciousness in a hospital or day surgery facility.
Whichever option is selected, the surgical area still needs appropriate pain control. Sedation helps with anxiety and awareness, but it does not replace the local anaesthetic used to numb the teeth and surrounding tissues.
Local anaesthetic, IV sedation and general anaesthetic compared
The main difference is how awake and aware you are during treatment.
All three options can provide appropriate conditions for wisdom teeth removal, but they involve different levels of preparation, monitoring and recovery.
| What to compare | Local anaesthetic | IV or twilight sedation | General anaesthetic |
|---|---|---|---|
| Are you awake? | Yes. You remain awake and aware. | You are deeply relaxed and drowsy but can usually respond to instructions. | No. You are unconscious. |
| Will the area be numb? | Yes. | Yes. Local anaesthetic is normally used as well. | Pain and awareness are controlled by the anaesthetic team, with local anaesthetic or other pain control used as clinically appropriate. |
| Will you remember it? | You will normally remember the procedure. | You may remember little, although memory loss is not guaranteed. | You should not be aware of or remember the procedure while unconscious. |
| Where is it performed? | Usually in the dental clinic. | In an appropriately equipped clinical setting. | In a hospital or suitable day surgery facility. |
| Who may be involved? | The treating dental practitioner and clinical team. | The treating dental practitioner plus an appropriately qualified sedation practitioner and monitoring team. | The treating dental practitioner, anaesthetist and hospital or day surgery team. |
| Fasting | Not normally required for local anaesthetic alone unless instructed for another reason. | Follow the specific fasting instructions provided by the sedation team. | Fasting is required according to the anaesthetist’s instructions. |
| Can you drive home? | Possibly after local anaesthetic alone, but confirm this with the treating clinician. | No. A responsible adult must take you home. | No. A responsible adult must take you home. |
| Initial recovery | Usually the quickest of the three options. | You will be monitored until sufficiently recovered, but drowsiness can continue afterwards. | You will wake in a monitored recovery area and may feel tired, nauseated or disorientated initially. |
| When it may be considered | Straightforward or selected surgical extractions when the patient is comfortable remaining awake. | Anxiety, strong gag reflex, multiple teeth or more involved treatment. | Selected complex cases, severe anxiety, special medical needs or treatment that is more appropriately performed in hospital. |
This comparison is general. Your instructions may differ depending on the medicines used, the number and position of your wisdom teeth and your medical history.
Wisdom teeth removal under local anaesthetic
Under local anaesthetic, you remain fully awake while the wisdom tooth and surrounding gum are numbed.
The medicine temporarily blocks pain signals travelling from the treated area to the brain.
Once the anaesthetic has taken effect, you should not feel sharp pain. You may still notice:
- Pressure around the tooth.
- Pushing or pulling sensations.
- Movement or vibration.
- Sounds from the dental instruments.
Feeling pressure does not mean that the anaesthetic has failed. However, you should tell the treating clinician immediately if you feel sharp pain so the area can be reassessed and more local anaesthetic can be considered.
When may local anaesthetic be enough?
Local anaesthetic may be suitable for:
- A wisdom tooth that has fully erupted.
- A relatively straightforward extraction.
- Selected impacted wisdom teeth.
- Patients who are comfortable remaining awake.
- Patients who would prefer to avoid the additional preparation and recovery associated with sedation.
A surgical extraction does not automatically require sedation or general anaesthetic. Some impacted teeth can still be removed under local anaesthetic when the patient and clinician agree that this is appropriate.
Advantages of local anaesthetic
- You avoid the drowsiness caused by sedative medicines.
- Preparation is generally simpler.
- Recovery from the anaesthetic is usually faster.
- The cost is generally lower than treatment with IV sedation or hospital-based general anaesthetic.
- You remain able to communicate normally throughout the procedure.
Possible limitations
- You remain aware of the procedure.
- You may hear instruments and feel pressure or movement.
- It may not suit severe dental anxiety or phobia.
- A longer or more involved procedure may feel difficult for some patients.
- Active inflammation or infection can sometimes affect how well local anaesthetic works in the immediate area.
Wisdom teeth removal under IV or twilight sedation
IV sedation uses medicine delivered through a vein to make you deeply relaxed, sleepy and less aware of the procedure.
At Toothsome, the IV twilight sedation service is administered in the clinic by a visiting sedation doctor.
Twilight sedation is sometimes described as sleep dentistry, but it is not the same as general anaesthetic. Under conscious or moderate sedation, you are not completely unconscious. You can usually respond purposefully when spoken to or gently prompted.
Many patients feel detached from what is happening and remember little afterwards. The amount you remember varies, so IV sedation should not be presented as a guarantee of complete amnesia.
Does IV sedation stop pain?
IV sedation primarily reduces anxiety and awareness. It does not replace local anaesthetic.
The wisdom tooth and surrounding tissues are normally numbed after you are sedated so the surgical area does not transmit sharp pain during treatment.
When may IV sedation be considered?
- Moderate or significant dental anxiety.
- A strong gag reflex.
- Difficulty remaining comfortable for a longer appointment.
- Removal of several wisdom teeth.
- Surgical or impacted wisdom teeth.
- A previous difficult dental experience.
- A preference for reduced awareness without undergoing general anaesthetic.
Advantages of IV sedation
- You may feel much calmer than with local anaesthetic alone.
- Your awareness of time and treatment is often reduced.
- You may remember little of the procedure.
- The depth of sedation can be adjusted by the sedation practitioner.
- It can allow several teeth to be treated in one appointment.
- It is performed without placing you into the fully unconscious state used in general anaesthesia.
Possible limitations
- You need additional medical assessment and monitoring.
- You must follow the fasting and medication instructions given to you.
- You cannot drive yourself home.
- You need a responsible adult to accompany you and support you afterwards.
- Drowsiness and reduced coordination can continue for the rest of the day.
- You may still retain some memories of the procedure.
- IV sedation adds to the total cost.
Sedation depth can change
Sedation exists on a spectrum. ANZCA notes that deeper sedation can progress unpredictably towards general anaesthesia, which is why appropriate training, patient assessment, monitoring, equipment and recovery processes are essential.
Wisdom teeth removal under general anaesthetic
Under general anaesthetic, you are placed into a carefully controlled state of unconsciousness and remain unaware of the wisdom teeth procedure.
An anaesthetist continuously monitors and manages your consciousness, breathing, oxygen level, heart rate, blood pressure and other responses.
At Toothsome, dental treatment under general anaesthetic is performed in a hospital or suitable day surgery setting. This pathway may be considered when treatment is complex, lengthy or cannot be completed comfortably using local anaesthetic or IV sedation.
When may general anaesthetic be considered?
- Multiple complex or deeply impacted wisdom teeth.
- Treatment expected to be lengthy or technically involved.
- Severe dental anxiety or phobia that cannot be managed adequately with other options.
- Special medical, behavioural or accessibility needs.
- A need for complete patient stillness.
- Several procedures being completed during one hospital session.
- A clinical assessment indicating that hospital-based treatment is more appropriate.
Advantages of general anaesthetic
- You are unconscious and unaware of the procedure.
- You do not need to manage the sights, sounds or sensations of surgery.
- It may facilitate complex or extensive treatment.
- It is delivered in a controlled hospital or day surgery environment.
- Anaesthetic care and recovery are managed by an appropriately trained medical team.
Possible limitations
- It requires hospital or day surgery admission.
- You must fast according to the anaesthetist’s instructions.
- Preparation and recovery usually take longer.
- You may experience nausea, dizziness, tiredness, shivering or a sore throat afterwards.
- You need an adult to take you home and remain available during the initial recovery period.
- Anaesthetist and facility fees add substantially to the total cost.
- General anaesthesia carries risks that must be discussed with the anaesthetist.
What is the difference between IV sedation and general anaesthetic?
With IV sedation you are deeply relaxed but not necessarily unconscious. With general anaesthetic you are fully unconscious.
Under IV sedation, you can usually respond to simple instructions even if you feel sleepy and later remember very little. Your breathing and other vital signs are monitored throughout treatment.
Under general anaesthetic, you do not respond normally to stimulation and the anaesthetist actively manages your airway, breathing, circulation and level of unconsciousness.
General anaesthetic is not automatically better because it produces a deeper level of unconsciousness. IV sedation is not automatically better because it avoids hospital admission. The choice depends on which option provides an appropriate balance of:
- Patient comfort.
- Surgical access.
- Medical suitability.
- Procedure complexity.
- Expected treatment time.
- Recovery requirements.
- Cost.
Will you feel pain during wisdom teeth removal?
You should not feel sharp surgical pain once the treatment area has been effectively numbed or anaesthetised.
With local anaesthetic or IV sedation, you may still feel pressure, movement or vibration during the extraction.1
Under general anaesthetic, you are unconscious and unaware of the procedure. Pain relief is then planned for the period after you wake.
Discomfort after the procedure is different from pain during the procedure. Once the local anaesthetic wears off, some pain, swelling and jaw stiffness are expected while the surgical areas begin to heal.
Which anaesthetic option may suit your wisdom teeth removal?
The option is selected by considering the patient and the procedure together.
The number of teeth alone is not enough to decide.
Removing one straightforward wisdom tooth
Local anaesthetic may be sufficient when the tooth is accessible and you are comfortable remaining awake. Sedation may still be considered when anxiety or another individual factor makes awake treatment difficult.
Removing all four wisdom teeth
All four wisdom teeth can sometimes be removed under local anaesthetic. Other patients may prefer or benefit from IV sedation, particularly when several teeth are impacted or they feel anxious about a longer procedure.
General anaesthetic may be considered for selected complex cases, but removing four teeth does not automatically require hospital treatment.
Removing an impacted wisdom tooth
An impacted tooth may require a surgical approach, but surgical removal can potentially be performed under any of the three options. The appropriate choice depends on the depth and position of the tooth, nearby structures, procedure length and patient comfort.
Severe dental anxiety
IV sedation may provide enough relaxation and reduced awareness for many anxious patients. General anaesthetic may be considered when the anxiety is severe or when other clinical factors make hospital treatment more suitable.
Medical conditions or regular medication
Your health may affect whether sedation or general anaesthetic is suitable. Tell the clinical team about:
- Heart or lung conditions.
- Obstructive sleep apnoea.
- Previous problems with sedation or anaesthesia.
- Medication allergies.
- Blood thinning medication.
- Diabetes medication.
- Pregnancy or breastfeeding.
- Alcohol or recreational drug use.
- Every prescription medicine, supplement and over the counter product you take.
Do not stop medication or change a dose unless the relevant clinician instructs you to do so.
What if you are frightened of wisdom teeth removal?
Being frightened does not mean that general anaesthetic is your only option.
The consultation should explore what you are worried about and whether information, local anaesthetic, IV sedation or hospital treatment would make the procedure manageable.
Patients may be concerned about:
- Feeling pain.
- Hearing or seeing the procedure.
- Needles.
- Loss of control.
- Gagging.
- Remembering the extraction.
- A previous difficult dental experience.
- Waking during general anaesthetic.
Tell Dr Willis exactly which part concerns you. A patient who is mainly worried about pain may feel comfortable once local anaesthetic is properly explained. Someone concerned about awareness or memory may prefer IV sedation. Another patient may require a hospital pathway.
The purpose is not to choose the deepest option by default. It is to choose an option that allows the treatment to be carried out appropriately while addressing your individual concerns.
Fasting, medication and preparation
Preparation depends on the anaesthetic plan, so follow the instructions provided specifically for your appointment.
| Preparation | Local anaesthetic | IV sedation | General anaesthetic |
|---|---|---|---|
| Medical history review | Required | Required | Required with anaesthetic assessment |
| Fasting | Usually not for local anaesthetic alone | Follow the sedation team’s instructions | Required according to hospital instructions |
| Medication review | Required | Required | Required |
| Escort home | Confirm with the clinic | Required | Required |
| Support afterwards | Helpful after surgery | Required during initial recovery | Required during initial recovery |
Do not copy another patient’s fasting instructions. The timing may depend on the procedure, medicines, appointment time and anaesthetic plan.
Fasting incorrectly can cause the procedure to be delayed or cancelled and may increase the risk of stomach contents entering the lungs during deeper anaesthesia.
Can you drive after wisdom teeth sedation or anaesthesia?
You must not drive yourself home after IV sedation or general anaesthetic.
Arrange for a responsible adult to collect you and follow all discharge instructions.
For at least the period specified by your clinical team, you may also be told not to:
- Drive or ride a motorcycle.
- Operate machinery.
- Drink alcohol.
- Travel alone on public transport.
- Sign legal documents.
- Make important financial or personal decisions.
- Care for children or another dependent person without support.
Toothsome advises patients not to drive, operate machinery or make important decisions for at least 24 hours after twilight sedation. General anaesthetic patients also need transport home and initial supervision according to the hospital team’s instructions.
After local anaesthetic alone, driving may be possible for some patients. Confirm this before the procedure, particularly if you have received other medication, feel unwell or have had a difficult extraction.
Risks and possible side effects
Every option carries potential risks, although the type and likelihood vary.
Your clinician must consider both the anaesthetic risks and the surgical risks of wisdom teeth removal.
Local anaesthetic
Possible issues include discomfort during injection, bruising, temporary numbness extending beyond the intended area, inadequate numbing, allergic reaction and very uncommon systemic complications.
IV sedation
Possible effects include drowsiness, dizziness, nausea, reduced coordination, changes in breathing or blood pressure, an unexpected reaction to medication and sedation becoming deeper than intended.
General anaesthetic
Common temporary effects can include nausea, vomiting, dizziness, tiredness, shivering and a sore throat. Less common or serious complications can include allergic reaction, breathing problems, aspiration, damage related to airway management and other anaesthetic complications.
Serious complications are uncommon, but no anaesthetic should be described as completely risk free. The person providing the sedation or anaesthetic will assess your medical history and explain risks relevant to you.
How much do IV sedation and general anaesthetic cost?
Sedation and general anaesthetic are charged in addition to the wisdom teeth procedure itself.
The final amount depends on the anaesthetic provider, procedure duration, hospital and treatment complexity.
At the time of publication, Toothsome lists the following approximate fees:
| Item | Published approximate fee |
|---|---|
| IV or twilight sedation | Approximately $800 |
| Anaesthetic fee for hospital treatment | Approximately $800 to $1,000 |
| Hospital or day surgery facility fee | Approximately $1,285 to $1,985 |
These figures are indicative and may change. Hospital, anaesthetist and surgical fees can be billed separately. A personal quote can only be prepared after Toothsome has assessed the wisdom teeth and confirmed the proposed treatment setting.

Frequently asked questions
What is the best anaesthetic for wisdom teeth removal?
There is no single best option. Local anaesthetic may suit straightforward treatment and patients who are comfortable remaining awake. IV sedation may suit anxiety or more involved procedures. General anaesthetic may be considered for selected complex cases or when hospital treatment is more appropriate.
Can wisdom teeth be removed under local anaesthetic?
Yes. Straightforward and selected surgical wisdom teeth can be removed under local anaesthetic. You remain awake, but the tooth and surrounding tissues are numbed so you should not feel sharp pain.
Are you awake during IV sedation for wisdom teeth removal?
You are not usually completely unconscious. Most patients are very relaxed and drowsy but can still respond to simple instructions. Awareness and memory are often reduced, although complete amnesia cannot be guaranteed.
Is IV sedation the same as general anaesthetic?
No. IV sedation creates a deeply relaxed and drowsy state, while general anaesthetic places you into controlled unconsciousness. General anaesthetic is performed with an anaesthetist in an appropriate hospital or day surgery environment.
Can I be completely asleep for wisdom teeth removal?
Yes. Selected patients can have wisdom teeth removed under general anaesthetic in a hospital or day surgery facility. An assessment is required to determine whether this option is clinically appropriate.
Do you need general anaesthetic to remove all four wisdom teeth?
Not necessarily. Some patients can have all four removed under local anaesthetic, while others may prefer or benefit from IV sedation. General anaesthetic may be considered when the surgery or individual circumstances make hospital treatment more appropriate.
Will I feel pain under IV sedation?
IV sedation itself mainly reduces anxiety and awareness. Local anaesthetic is normally used alongside it to numb the surgical area. You may still feel pressure or movement, but you should not feel sharp pain once the area is effectively numbed.
Can I drive home after wisdom teeth sedation?
No. You must arrange for a responsible adult to take you home after IV sedation or general anaesthetic. You must also follow the instructions about driving, alcohol, machinery and important decisions during your recovery.
