If you’re experiencing pain at the back of your mouth, it could be a sign that your wisdom teeth are making their appearance. These third molars usually erupt between the ages of 17 and 25, but the process isn’t always smooth. For many, the arrival of wisdom teeth brings discomfort, swelling, and tenderness — leaving one common question: “How long will this pain last?”
Why Wisdom Teeth Cause Pain
Wisdom teeth often don’t have enough room to erupt properly. As they push through the gums, they can cause pressure, inflammation, and sometimes infection. Pain can also occur if the tooth is partially erupted (breaking through only part of the gum), which creates a flap of tissue where food and bacteria can get trapped. This may lead to pericoronitis — a painful gum infection.
Typical Duration of Pain
For most people, mild to moderate discomfort lasts about 3 to 7 days during the tooth’s eruption phase. However, the exact duration depends on several factors:
- Eruption speed: Some wisdom teeth come in quickly, while others take weeks or months to fully emerge.
- Gum and bone structure: Tight gums or dense bone can make the process slower and more uncomfortable.
- Position of the tooth: Impacted or angled wisdom teeth can cause prolonged pain or recurring flare-ups.
In cases where the tooth is erupting normally, pain tends to lessen once it fully breaks through the gum line.
When the Pain Lasts Longer
If the pain persists beyond a week or keeps returning, it may indicate:
- Partial eruption with trapped debris
- Infection or swelling around the tooth
- Impaction (tooth stuck against another tooth or bone)
- Crowding or pressure on nearby teeth
In these situations, pain won’t simply “go away with time.” A dental examination is essential to determine whether removal or other treatment is needed.
Ways to Soothe Wisdom Tooth Pain
While waiting for the tooth to settle, you can manage discomfort with:
- Warm salt water rinses to reduce bacteria and inflammation
- Cold compresses to ease swelling
- Over-the-counter pain relievers (as advised by your dentist)
- Gentle brushing around the area to keep it clean without irritating the gums
Avoid poking the area with your tongue or fingers, as this can worsen irritation or introduce bacteria.
When to See a Dentist
You should book a dental appointment if you notice:
- Severe or throbbing pain lasting more than a week
- Difficulty opening your mouth or swallowing
- Swelling in the jaw or cheek
- Bad breath or a foul taste in your mouth
These could be signs of infection or impaction that need professional care.
Bottom Line
Wisdom tooth pain is common and usually temporary, often settling within a week as the tooth erupts. However, persistent or intense pain isn’t something to ignore. A quick visit to your dentist can help you determine whether it’s a normal eruption or a sign that the tooth needs attention — ensuring relief and protecting your oral health in the long run.
