Wisdom Teeth Removal in Hilbert
Wisdom teeth causing problems? Let's sort it out.
Assessment and removal of impacted or problematic third molars (wisdom teeth) at Sienna Smiles, Hilbert. According to the Australian Dental Association, wisdom teeth cause problems in up to 85% of people at some point in their lifetime, making them one of the most commonly extracted teeth. OPG (orthopantomogram) radiographic assessment included. Sedation options may be discussed at your consultation.
Why wisdom teeth become an issue
Wisdom teeth — clinically termed third molars — are the last teeth to erupt, usually between the ages of 17 and 25. Because contemporary human jaws are frequently smaller than those of our evolutionary ancestors, there is often insufficient space in the dental arch to accommodate them. HealthDirect Australia notes that impaction affects up to 70–80% of young adults, making wisdom teeth the most commonly impacted teeth in the human dentition.
Impaction
When there is insufficient space in the retromolar region, wisdom teeth may erupt at an angle or remain partially or fully impacted within the alveolar bone. The four classifications of impaction are: mesioangular (angled toward the second molar — accounting for approximately 43% of impactions), horizontal (lying on its side), vertical (erupting straight but blocked by bone or soft tissue), and distoangular (angled away from the second molar). Each classification carries different surgical complexity and risk considerations.
Crowding of existing teeth
Emerging wisdom teeth may exert pressure on adjacent teeth. Whether this causes meaningful crowding is assessed on an individual basis using clinical examination and X-ray findings.
Increased decay risk
Partially erupted wisdom teeth are difficult to clean effectively. The gap between the tooth and gum traps food debris and bacteria, increasing the risk of decay in both the wisdom tooth and the adjacent second molar.
Pericoronitis
When a wisdom tooth is partially erupted, the overlying gum flap (operculum) can harbour anaerobic bacteria and become acutely infected — a condition called pericoronitis. HealthDirect Australia identifies pericoronitis as one of the most common indications for wisdom tooth removal. Symptoms include localised pain, gingival swelling, trismus (difficulty opening the mouth), and sometimes referred otalgia (ear pain). Recurrent pericoronitis is a strong clinical indication for extraction.
Damage to adjacent teeth
Mesially impacted wisdom teeth press against the second molar's root, potentially causing root resorption or decay on the contact surface. This can compromise a tooth that would otherwise be healthy. If a second molar is lost as a result, replacement options such as [dental implants](/dental-implants) may be considered.
Not always — it depends
Removal is not automatically necessary. The Australian Dental Association advises against prophylactic extraction of asymptomatic, fully erupted, disease-free wisdom teeth. Many people have third molars that erupt into functional occlusion, remain symptom-free, and can be cleaned adequately with standard oral hygiene measures. For these patients, periodic clinical and radiographic monitoring is an appropriate and evidence-based approach.
When monitoring is appropriate
- The tooth is fully erupted and correctly positioned
- You can clean it thoroughly with a toothbrush and floss
- There are no signs of decay, infection, or pathology on X-ray
- The tooth is not causing pressure, pain, or crowding
When removal is typically recommended
- Recurrent infection — repeated episodes of pericoronitis or abscess
- Decay — the wisdom tooth or adjacent second molar has decay that cannot be adequately restored due to position
- Crowding or orthodontic concerns — assessed case-by-case based on clinical and radiographic findings
- Pathology on OPG — cyst, tumour, or significant bone change identified on orthopantomogram (panoramic X-ray)
- Root resorption — the wisdom tooth is damaging an adjacent tooth's root
Diagnostic standard
An OPG (orthopantomogram) — a panoramic radiograph of the entire maxillofacial complex — is the standard diagnostic imaging tool for wisdom tooth assessment. It provides a comprehensive view of each third molar’s position, angulation, root morphology, relationship to the inferior alveolar nerve canal (mandibular nerve), and proximity to the maxillary sinus. This information is essential for accurate surgical planning and risk assessment.
Step by step: your appointment
OPG X-ray assessment and treatment plan
Your dentist reviews your OPG (orthopantomogram) — a panoramic X-ray that shows all teeth, roots, and surrounding bone. If you do not have a current OPG, one will be arranged. Your dentist explains findings, discusses options, and provides a written treatment plan with costs before any procedure is scheduled.
Anaesthetic options discussed
Local anaesthetic is standard for wisdom tooth removal and is effective for most patients. If you have significant anxiety or the procedure is complex, sedation options may be discussed at your consultation — suitability is assessed on a case-by-case basis. You will always be informed of what is involved before consenting.
The procedure
Local anaesthetic is administered to numb the area. A simple extraction is used when the tooth is fully erupted — the tooth is loosened and removed in one piece. A surgical extraction is required for impacted teeth — a small incision may be made, and the tooth may be sectioned to allow safe removal. You should feel pressure but not sharp pain. Tell your dentist immediately if you do.
Gauze and haemostasis
Gauze is placed over the extraction socket and you will be asked to bite down firmly for 30–45 minutes to allow initial clot formation. Steady pressure is the most effective way to control bleeding in the first hour.
Aftercare instructions
Before you leave, you will receive written aftercare instructions covering diet, oral hygiene, activity restrictions, and what to do if you experience unexpected symptoms. Recovery typically takes 3–7 days, though individual recovery varies based on the complexity of the extraction and your overall health.
What to expect after removal
Recovery after wisdom tooth removal typically takes 3–7 days, though individual recovery varies based on the complexity of the extraction and the patient’s overall health. HealthDirect Australia notes that surgical removal of deeply impacted lower wisdom teeth generally involves more post-operative swelling and a longer healing period than simple extraction of fully erupted teeth. The guidance below applies to most patients; always follow any specific instructions from your treating dentist.
Rest as much as possible. Apply an ice pack to the outside of your cheek in 15-minute intervals to reduce swelling. Bite firmly on gauze for 30–45 minutes to control bleeding. Eat soft, cool foods only (yoghurt, ice cream, smoothies without a straw). Take pain relief as directed. Do not rinse, spit forcefully, or probe the socket.
Swelling typically peaks around day 2–3 then begins to reduce. Switch from ice to warm compresses if helpful from day 3. Commence gentle warm saltwater rinses from day 2 (half a teaspoon of salt in a glass of warm water, held gently — do not swish forcefully). Continue soft diet. Some bruising on the cheek is normal.
Gradual improvement each day. Swelling and discomfort should be clearly reducing. You may carefully reintroduce soft normal foods as tolerated. Continue saltwater rinses. If you had dissolvable sutures, they will begin to dissolve around day 5–7. Attend your review appointment as scheduled.
Dry socket — know the signs
Dry socket (alveolar osteitis) occurs when the blood clot in the extraction socket is dislodged or fails to form, exposing the underlying alveolar bone and nerve endings. According to HealthDirect Australia, dry socket occurs in approximately 2–5% of all dental extractions and up to 30% of mandibular third molar (lower wisdom tooth) extractions. It typically develops 2–4 days after the procedure and causes severe, localised, throbbing pain that may radiate to the ear or ipsilateral jaw — noticeably worse than normal post-operative soreness. You may notice an empty-looking socket, a foul taste, or halitosis.
Contact Sienna Smiles immediately if you suspect dry socket. Do not wait for your next scheduled appointment. Dry socket is treatable and manageable when addressed promptly.
Reducing your dry socket risk
- Do not smoke for at least 72 hours post-extraction — smoking significantly increases risk
- Avoid sucking through a straw for 24–48 hours
- Do not rinse forcefully on day one — gentle rinsing from day two
- Follow a soft diet and avoid alcohol for the first 48 hours
