Oral infections are more common than you might think — and they don’t just cause discomfort. If left untreated, an infection in your mouth can spread to other parts of the body and lead to serious health complications.
Knowing the signs early can help you seek treatment before things get worse.
At Every Smile Dentistry, we’re here to help you spot the warning signs and get the care you need to protect your oral and overall health.
What Is an Oral Infection?
An oral infection occurs when harmful bacteria, viruses, or fungi invade the tissues in your mouth.
These infections may affect the gums, teeth, tongue, lips, or inner cheeks, and they can range from mild to severe.
Common Types of Oral Infections
1. Gingivitis and Periodontitis
- Cause: Plaque buildup and poor oral hygiene
- Symptoms: Red, swollen, or bleeding gums; bad breath; gum recession
- Treatment: Professional cleaning, improved oral hygiene, and possible periodontal therapy
2. Dental Abscess
- Cause: Untreated tooth decay or gum disease leading to pus build-up
- Symptoms: Throbbing pain, swelling in the jaw or face, fever, foul taste in the mouth
- Treatment: Drainage of the abscess, antibiotics, root canal, or tooth extraction
3. Oral Thrush (Candidiasis)
- Cause: Fungal infection (Candida), often due to antibiotics, dry mouth, or weakened immunity
- Symptoms: White patches on the tongue or cheeks, burning sensation, difficulty swallowing
- Treatment: Antifungal medications, improved oral hygiene
4. Herpes Simplex Virus (Cold Sores)
- Cause: Viral infection (HSV-1)
- Symptoms: Painful blisters around the mouth or lips, itching or burning before the sore appears
- Treatment: Antiviral creams or tablets, keeping the area clean and dry
5. Pericoronitis
- Cause: Infection around a partially erupted wisdom tooth
- Symptoms: Pain and swelling near the back of the mouth, difficulty opening the mouth
- Treatment: Cleaning the area, antibiotics, or extraction of the wisdom tooth
Warning Signs to Watch For
If you notice any of the following, it’s time to book an appointment with your dentist:
- Persistent bad breath or bad taste
- Pain or swelling in the gums, jaw, or face
- Bleeding when brushing or flossing
- Loose teeth
- White or red patches in the mouth
- Fever, fatigue, or swollen lymph nodes in the neck
How to Prevent Oral Infections
1. Brush and Floss Daily
Good oral hygiene is your first line of defence against infections. Brush twice a day with fluoride toothpaste and floss once a day to remove bacteria between the teeth.
2. Avoid Tobacco Products
Smoking and chewing tobacco weaken your immune system and increase your risk of oral infections and gum disease.
3. Stay Hydrated
A dry mouth provides a perfect environment for harmful bacteria. Drink water throughout the day to support saliva production.
4. Eat a Balanced Diet
Foods rich in vitamins A, C, and D strengthen your immune system and support oral health.
5. Visit Your Dentist Regularly
Routine check-ups help catch problems early and keep your mouth infection-free.
