What to Expect During Wisdom Teeth Surgery

A Step-by-Step Walkthrough So You Know Exactly What Is Coming

Not knowing what to expect is often the worst part of any dental procedure. If you have been told your wisdom teeth need to come out, it is completely natural to feel a bit nervous — especially if this is your first experience with dental surgery.

At Compass Dental in Darwin, we have performed thousands of wisdom teeth extractions over the past decade. We find that when patients understand exactly what will happen — before, during, and after — most of that anxiety fades away.

This article gives you an honest, detailed walkthrough of the entire process, from your first consultation through to recovery.

Before the Procedure

Your Initial Consultation

Everything begins with an assessment. Your dentist will examine your mouth, take X-rays (usually an OPG panoramic X-ray, or a CBCT scan for complex cases), discuss the findings with you, and explain costs and options so there are no surprises on the day. This consultation is also your opportunity to ask questions.

Preparing for the Day

For patients having local anaesthetic and happy gas, preparation is straightforward:

Eat a light meal before your appointment — you do not need to fast.
Wear comfortable clothing — you will be in the dental chair for a while.
Most patients can drive themselves home, though you can arrange a lift if you prefer.
Take any prescribed medications as directed.
Avoid alcohol for at least 24 hours before the procedure.

If you are a new patient, allow extra time for paperwork.

During the Procedure

Getting Settled

When you arrive, the dental team will welcome you, confirm the treatment plan, and get you comfortable in the chair. If you are feeling anxious, let the team know — they deal with nervous patients every day and know how to help.

Sedation: Staying Comfortable Throughout

The vast majority of wisdom teeth extractions at Compass Dental are performed using local anaesthetic combined with happy gas (nitrous oxide). Here is what each does:

Local anaesthetic is a numbing injection given directly to the area around the wisdom tooth. It blocks pain signals completely. You will feel pressure and movement, but you should not feel pain. Your dentist uses a topical numbing gel on the gum first so you barely feel the needle.

Happy gas is a mixture of nitrous oxide and oxygen delivered through a small nose mask. Within a couple of minutes, you will feel calm, relaxed, and slightly floaty. You remain fully conscious and can communicate with the dental team — you are simply less concerned about what is happening. Happy gas takes effect quickly and wears off just as fast, with no lingering drowsiness, and most patients are able to drive home.

A note on deeper sedation: For the small number of patients whose circumstances genuinely require deeper sedation — such as extremely complex extractions or severe dental phobia that does not respond to happy gas — IV sedation or general anaesthetic may be clinically warranted. These are not offered at Compass Dental Care; if your case requires one of these, we will refer you to a specialist sedation clinic or hospital-based service. The overwhelming majority of patients find local anaesthetic and happy gas provides all the comfort they need.

The Extraction Process

Once the area is fully numb and you are comfortable, your dentist begins the extraction. Here is what happens, step by step:

For a simple extraction (where the tooth has fully come through the gum):

The dentist uses an instrument called an elevator to loosen the tooth within its socket.
Once loosened, forceps are used to gently rock the tooth back and forth until it can be lifted out.
The whole process can take just a few minutes per tooth.

For a surgical extraction (where the tooth is partially erupted or impacted):

A small incision is made in the gum tissue to expose the tooth.
In some cases, a small amount of bone around the tooth may need to be removed to gain access.
The tooth may be divided into sections — this is very common and makes it easier to remove each piece without disturbing the surrounding bone.
The pieces are removed one by one.
The site is cleaned thoroughly.
Dissolvable stitches are placed to close the gum. These typically dissolve on their own within one to two weeks.

You will feel pressure during the extraction — sometimes quite firm pressure — but it should not be painful. If at any point you feel sharp pain, raise your hand and your dentist will stop and administer more local anaesthetic.

How Long Does It Take?

The time required depends on how many teeth are being removed and how complex the extractions are:

One straightforward tooth: 15 to 20 minutes
Four wisdom teeth (mixed complexity): 45 minutes to 1.5 hours
Complex impacted teeth: Longer, depending on the individual case

Your dentist will give you a realistic time estimate during your consultation.

Immediately After the Procedure

In the Chair

Once the extractions are complete, the dental team will:

Remove the happy gas mask and let you breathe normal air for a few minutes
Place gauze pads over the extraction sites and ask you to bite down gently to help control bleeding
Give you detailed written aftercare instructions
Prescribe any necessary medications — usually pain relief and sometimes antibiotics
Schedule a follow-up appointment if needed

You will usually sit for five to ten minutes before getting up, just to make sure you are feeling steady.

Heading Home

Happy gas clears from your system quickly, so most patients feel clear-headed within minutes. Your mouth will still be numb from the local anaesthetic for two to four hours, so be careful not to bite your lip, tongue, or cheek.

Key things to remember:

Keep biting gently on the gauze pads for at least 30 minutes
Do not rinse, spit, or use a straw for the first 24 hours — this can dislodge the blood clot
Stick to soft, cool foods for the first day
Take pain relief before the local anaesthetic wears off so the medication has time to take effect

What to Expect in the Days After Surgery

Day 1

Expect some swelling, which usually peaks around 24 to 48 hours after the procedure. Mild to moderate discomfort is normal and should be manageable with the prescribed or recommended pain relief. Some oozing of blood is normal — if bleeding is heavy or does not settle, contact the clinic.

Days 2 to 3

Swelling may increase slightly before it starts to improve. Bruising on the outside of the jaw or cheek is common and nothing to worry about. You can begin gently rinsing with warm saltwater (half a teaspoon of salt in a glass of warm water) after meals.

Days 4 to 7

Most patients notice a significant improvement by this stage. Swelling subsides, pain decreases, and you can gradually return to a more normal diet. Avoid hard, crunchy, or spicy foods until the sites have healed.

Weeks 2 to 4

The gum tissue continues to heal and close over the extraction sites. Dissolvable stitches should be gone by now. Most patients are fully back to normal within two to three weeks.

When to Contact the Clinic

Call Compass Dental or seek urgent care if you experience:

Heavy bleeding that does not stop with gentle pressure on gauze
Increasing pain after the first few days, rather than improving — this could indicate a dry socket
Fever or feeling generally unwell
Difficulty swallowing or breathing
Numbness that persists beyond 24 hours in your lip, tongue, or chin
Pus or a foul taste from the extraction site

We can often see patients with post-operative concerns on the same day or the next day. If you are travelling from a remote Northern Territory community, call us and we will do our best to accommodate you promptly.
