Wisdom teeth are the last molars to erupt, often between the ages of 17 and 25. While some emerge without issue, many cause complicationsespecially when they become impacted or infected. An infected wisdom tooth can be incredibly painful and potentially dangerous if not treated promptly. Knowing how to manage the infection with proper first aid until you can see a dentist is critical.
At McLevin Dental, we regularly treat patients in Scarborough with wisdom tooth infections. Heres your complete guide to recognizing symptoms, applying emergency relief, and understanding when to seek immediate dental care.
What Causes a Wisdom Tooth Infection?
Infection in a wisdom toothknown as pericoronitisusually occurs when the tooth is partially erupted, leaving a flap of gum tissue where bacteria, food debris, and plaque can accumulate.
Common causes include:
Impacted wisdom teeth trapped under the gums
Poor oral hygiene around the erupting tooth
Bacterial buildup in gum pockets
Cavities or decay in the wisdom tooth or neighboring molar
Trauma to the soft tissue around the tooth
Signs and Symptoms of an Infected Wisdom Tooth
Symptoms can escalate quickly, so early detection is key. Watch for:
Persistent pain or throbbing in the back of the mouth
Swollen, red, or bleeding gums near the tooth
Bad breath or a foul taste
Jaw stiffness or difficulty opening the mouth
Pus discharge near the tooth
Fever or general discomfort in advanced cases
Swollen lymph nodes in the neck
If left untreated, the infection can spread to surrounding tissues, jawbone, or even the bloodstreamso immediate care is crucial.
First Aid Steps for an Infected Wisdom Tooth
While professional treatment is essential, these first aid measures can help manage symptoms and prevent worsening until your dental appointment.
1. Rinse with Warm Salt Water
Salt water rinses help reduce bacteria, relieve pain, and soothe inflamed gums.
How to use:
Mix ½ teaspoon of salt in a cup of warm water
Rinse for 30 seconds, focusing on the affected area
Repeat 34 times daily
Avoid mouthwashes with alcoholthey can irritate the infection.
2. Apply a Cold Compress
A cold pack can reduce inflammation and provide temporary pain relief.
Instructions:
Wrap ice in a towel or use a cold gel pack
Apply to the outside of your cheek for 15 minutes
Repeat every few hours as needed
This method helps with jaw swelling and tenderness.
3. Take Over-the-Counter Pain Medication
Pain relievers like ibuprofen or acetaminophen can control discomfort and reduce inflammation. Follow dosing instructions carefully and consult a doctor if you have any pre-existing conditions.
Avoid:
Aspirin for children
Applying painkillers directly to the gumsthis can cause tissue damage
4. Keep the Area Clean
Brush gently around the wisdom tooth with a soft-bristled toothbrush to remove plaque buildup. Avoid hard or deep brushing, which could irritate swollen gums further.
You can also use an interdental brush or water flosser to clean around the toothcarefully and gently.
5. Avoid Aggravating Foods and Drinks
Until the infection is treated:
Stick to soft foods (yogurt, soup, oatmeal)
Avoid spicy, crunchy, or acidic foods
Drink plenty of water
Do not use a strawit may aggravate gum inflammation
When to See a Dentist Immediately
Dont wait for symptoms to improve on their own. Contact your dentist if you experience:
Severe, worsening pain
Pus or foul discharge
Fever or chills
Difficulty swallowing or breathing
Swelling that spreads to the jaw or face
A wisdom tooth thats partially erupted for more than a few weeks
These are signs that the infection may be spreading or worsening. At McLevin Dental, we offer same-day emergency appointments for infections, swelling, and tooth pain.
How Dentists Treat Infected Wisdom Teeth
Treatment depends on the severity of the infection:
1. Antibiotics
In mild to moderate cases, a course of antibiotics may be prescribed to reduce infection and inflammation before further dental work is done.
2. Irrigation and Cleaning
Your dentist may clean the area thoroughly, flush out pus and debris, and remove the flap of gum tissue if it’s trapping bacteria.
3. Tooth Extraction
If the wisdom tooth is severely infected or impacted, it may need to be extracted. Removal eliminates the source of infection and prevents future problems.
At McLevin Dental, we use modern, minimally invasive techniques for wisdom tooth removal with maximum comfort and fast recovery.
Preventing Future Wisdom Tooth Infections
Some people never develop complications from wisdom teeth, but for many, preventive removal is the best option.
To reduce your risk:
Schedule regular dental checkups and X-rays
Practice meticulous oral hygiene, especially around back molars
Use a soft toothbrush and rinse regularly with salt water
Consider early removal before impaction or infection occurs
If your wisdom teeth are partially erupted or showing signs of problems, consult your dentist before complications begin.
