Wisdom Tooth Infection: 10 Warning Signs To Watch Out For

Last updated on September 29th, 2025

Wisdom tooth infection is one of the most common dental problems faced by young adults and adults alike.

At our dental clinic in Whitefield, we often meet patients who confuse a simple wisdom tooth hurting with a more serious infection.

The truth is, an untreated wisdom tooth impaction can silently lead to complications like swelling, gum disease, or even bone damage. Knowing the warning signs early can save you pain, time, and cost. 

But what exactly should you watch out for? Let’s explore together.

Why Wisdom Tooth Infection Happens

Wisdom teeth usually erupt between the ages of 17 and 25. When there isn’t enough space in your jaw, they may grow at odd angles, partially erupt, or remain stuck beneath the gums; this is called wisdom tooth impaction.

Impacted teeth trap food and bacteria, which can cause infections. These infections often start small but can worsen quickly if left untreated.

10 Warning Signs of Wisdom Tooth Infection

1. Persistent Pain

If your wisdom tooth is hurting for days without relief, it may not just be “normal teething pain”. Constant or throbbing pain often points to infection beneath the gums.

2. Swollen Gums

Infected wisdom teeth often cause red, inflamed, or swollen gums near the tooth. This swelling makes chewing or even brushing difficult.

3. Bad Breath

A foul odor (bad breath) that doesn’t go away with brushing can signal trapped bacteria around the wisdom tooth.

4. Difficulty Opening Mouth

Infections sometimes spread to the jaw muscles, making it painful to open your mouth fully.

5. Swelling on the Jaw or Face

Visible swelling on one side of the face is often linked with a deep infection from a wisdom tooth impaction.

6. Bleeding Gums

Gums that bleed when eating or brushing, especially near the wisdom tooth, could mean an infection is present.

7. Unpleasant Taste in Mouth

You may notice a metallic or bitter taste due to pus drainage from the infected tooth.

8. Ear Pain or Headaches

The pain from wisdom teeth can radiate, causing discomfort in the ears or headaches near the jaw.

9. Fever or Fatigue

If infection spreads, it can trigger fever, body fatigue, or a general feeling of being unwell.

10. Difficulty Chewing

Pain or discomfort while chewing, especially near the infected area, is a strong sign to see your dentist.

Wisdom Tooth Pain Treatment Options

If you have one or more of these warning signs, timely treatment is essential. Here are the common approaches dentists suggest:

Treatment OptionWhen It’s NeededWhat It Involves
AntibioticsMild infectionControls bacterial spread temporarily
Cleaning & IrrigationFood stuck under gumsRemoves debris and bacteria
Wisdom tooth extractionSevere infection, impaction, or repeated painRemoval of the infected tooth

Pro Tip: Temporary relief with home remedies like saltwater rinses is possible, but only a dentist can provide a permanent solution.

Tips to Prevent Wisdom Tooth Infection

  • Brush and floss carefully around wisdom teeth.
  • Rinse with warm salt water if gums feel sore.
  • Avoid sugary or sticky foods that can get trapped.
  • Schedule regular dental check-ups.
  • Don’t delay treatment if your wisdom tooth is hurting often.

FAQs on Wisdom Teeth

At which age do wisdom teeth come?
Wisdom teeth usually erupt between 17 and 25 years, but in some cases, they may appear earlier or later depending on jaw space and genetics.

Is a wisdom tooth painful?
Not always. Some erupt without issues, but pain often occurs when there is impaction, infection, or not enough room in the jaw.

Does a wisdom tooth need to be removed?
Not in all cases. If it erupts properly and causes no issues, removal may not be required. Infections or impactions, however, usually need extraction.

What exactly is a wisdom tooth?
Wisdom teeth are the last set of molars located at the back of the mouth, designed to help in chewing. They often erupt in late teens or early adulthood.
