Wisdom teeth are the last molars to appear, usually between the ages of 17 and 25. Some people experience no issues as they erupt, while others develop symptoms such as discomfort, swelling, infection, or problems affecting nearby teeth.
Understanding when wisdom teeth may need removal can help you make informed decisions in consultation with your dentist.
1. What are wisdom teeth?
Wisdom teeth are the third set of molars located at the very back of the mouth — typically two on the top and two on the bottom.
Because they erupt later than other teeth, there may be limited space in the jaw. This can lead to wisdom teeth becoming:
- Impacted (unable to fully erupt due to bone or gum coverage)
- Partially erupted, creating a gum flap that can trap food and bacteria
- Angled or tilted, placing pressure on the tooth in front
Not all impacted or partially erupted wisdom teeth require removal, but they may require monitoring.
2. Signs your wisdom teeth may be a problem
Some wisdom teeth cause symptoms, while others may appear problematic only on imaging such as X-rays.
Common signs include:
- Pain or tenderness at the back of the mouth
- Swelling around the gums or jaw
- Difficulty opening your mouth fully
- Bad breath or an ongoing unpleasant taste
- Repeated irritation or infection around the wisdom tooth area
Because wisdom tooth issues may develop gradually, regular dental check-ups are important, particularly in the late teens and twenties.
3. Why dentists may recommend removal
A dentist may recommend removing a wisdom tooth if it is contributing to:
- Persistent pain or recurring infection
- Damage to the tooth in front
- Tooth decay that cannot be effectively treated or cleaned
- Gum disease in the area
- Pathology such as cysts (in some cases)
Partially erupted wisdom teeth can create a pocket that collects bacteria and debris, sometimes leading to pericoronitis (gum infection around the tooth). In these cases, our dentist may discuss whether removal is appropriate.
4. Do all wisdom teeth need to be removed?
No. Wisdom teeth may not require removal if they are:
- Fully erupted
- Positioned normally
- Easy to clean and maintain
- Not causing symptoms or damage
In some cases, your dentist may recommend monitoring the tooth over time.
A decision may be influenced by factors such as:
- Your age and general health
- X-ray findings
- Risk of future problems
- Your ability to clean the area effectively
5. What happens during wisdom teeth removal?
Wisdom tooth removal can be performed in different settings depending on complexity, your medical history, and preference. Treatment may involve:
- Local anaesthetic in the dental chair
- Sedation (in some cases, for anxiety or complex procedures)
- General anaesthetic in hospital for more complex extractions
During the procedure, the clinician may:
- Numb the area
- Remove gum and/or bone if needed
- Remove the tooth whole or in sections
- Clean the area and place stitches if required
Your dentist will provide aftercare instructions to support healing.
6. Recovery and aftercare
Most people experience improvement in discomfort within a few days, though healing times vary.
To support recovery:
- Rest for the first day or two
- Use cold packs to help reduce swelling
- Take pain relief as recommended
- Eat soft foods and avoid very hot, spicy, or crunchy foods
- Avoid smoking and using straws (these can interfere with healing)
Contact Bendigo dentist if you notice:
- Increasing pain after a few days
- A bad taste, smell, or discharge from the area
- Fever, chills, or difficulty swallowing
These may indicate complications such as dry socket or infection, which may require prompt professional care.
7. Costs and insurance
The cost of wisdom tooth removal depends on several factors, including:
- The number of teeth being removed
- Whether the procedure is performed in-chair or in hospital
- Complexity of the tooth position
- Whether sedation or general anaesthetic is involved
Private health insurance with hospital and/or dental extras may cover part of the treatment cost depending on your level of cover.
It may be helpful to request:
- A written estimate
- Relevant item numbers to check with your health fund
- An explanation of potential out-of-pocket expenses
In Bendigo, because dental care is commonly privately funded, understanding your coverage and any gap fees before treatment can assist with planning.
8. The bottom line
Not every wisdom tooth needs removal, but teeth that are causing symptoms or complications may require assessment and treatment.
If you are experiencing pain or recurring swelling at the back of your mouth — or if your dentist has recommended a wisdom tooth assessment — it may be worthwhile discussing your options.
