Wisdom teeth — your third molars — usually emerge between the ages of 17 and 25. But just because they are coming through does not automatically mean they need to be removed. Here are the signs to watch for.
Signs Your Wisdom Tooth May Need Removal
1. Pain or Tenderness at the Back of the Mouth
Dull, aching pain at the back of your jaw is one of the most common signs. This pain may come and go, often worsening when you chew or open your mouth wide. Recurring pain usually indicates impaction or pressure against the adjacent tooth.
2. Swollen or Bleeding Gums Behind Your Last Molar
When a wisdom tooth partially erupts, a flap of gum tissue can form over it, trapping food and bacteria. The gum becomes red, swollen, and tender — a condition called pericoronitis. This is a strong indication the tooth should come out.
3. Difficulty Opening Your Mouth Fully
Stiffness or reduced jaw mobility (trismus) may result from an impacted wisdom tooth causing inflammation in surrounding tissues.
4. Bad Breath or Unpleasant Taste
Food and bacteria trapped around a partially erupted wisdom tooth can cause persistent bad breath, even with regular brushing. If the odour comes from the back of your mouth, your wisdom tooth may be the cause.
5. Recurring Infections
If you have had one or more episodes of pericoronitis, the tooth should be removed. Each infection tends to be more severe, and the risk of spreading increases.
6. Visible Decay or Damage to the Adjacent Tooth
Wisdom teeth growing at an angle can push against the second molar, causing decay on its back surface or damaging its root. This is often detected on X-ray before you feel symptoms.
7. A Cyst on X-ray
In rare cases, a cyst develops around an impacted wisdom tooth. Detected on routine X-rays, this requires prompt removal to prevent jawbone damage.
When Is It Safe to Leave Wisdom Teeth Alone?
Your dentist may recommend monitoring rather than extracting if your wisdom teeth are:
- Fully erupted and properly positioned
- Bite-aligned — meeting the opposing tooth normally
- Easy to clean — you can brush and floss around them
- Not causing symptoms — no pain, swelling, or infections
- Not affecting adjacent teeth — confirmed on X-ray
What Happens If You Ignore a Problematic Wisdom Tooth?
- Worsening infections that can spread to the throat, neck, or cheek
- Damage to the adjacent tooth that may then also need treatment
- Cyst formation eroding the jawbone
- Increased surgical difficulty — the longer you wait, the harder the extraction
- Longer recovery in older patients
Our recommendation: If you are experiencing any of the symptoms above, have it assessed sooner rather than later. At Trust Dental Surgery, surgical extraction is 100% Medisave claimable (up to $1,250 per tooth).
How We Assess Your Wisdom Teeth
- Examine your mouth — checking for impaction, swelling, or decay
- Take X-rays — an OPG panoramic X-ray shows all four wisdom teeth
- Explain findings — we show you the X-ray and explain clearly
- Discuss options — timing, one side or both, recovery expectations
