Healthy gums are the foundation of a strong and beautiful smile. Normally, gums are firm, pale pink, and fit tightly around your teeth. However, if you notice swollen gums around a tooth, redness, or tenderness, it is a sign that something is not right.
Swollen gums—medically called gingival swelling—can range from mild irritation to a serious infection. In many cases, it is one of the early warning signs of tooth pain and dental infection, and should never be ignored.
In this complete guide, you will learn the causes of swollen gums, symptoms to watch for, effective treatments, and when you should see a dentist.
What Causes Swollen Gums Around a Tooth?
1. Poor Oral Hygiene and Gingivitis (Most Common Cause)
The most common reason for swollen gums is plaque buildup due to poor oral hygiene.
When you eat sugary or starchy foods, bacteria form a sticky layer called plaque. If not removed, it hardens into tartar and irritates the gums, causing:
- Redness
- Swelling
- Bleeding while brushing
This early stage is called gingivitis, and it is reversible.

2. Periodontitis (Advanced Gum Disease)
If gingivitis is ignored, it progresses into periodontitis—a serious gum infection.
This leads to:
- Gum recession
- Bone loss
- Loose teeth
- Persistent swelling
It is also linked to systemic conditions like diabetes and heart disease.
3. Swelling Around One Tooth (Localized Infection)
If swelling is present around a single tooth, it may indicate:
- Food stuck between teeth
- Gum infection
- Early abscess

4. Dental Abscess (Serious Cause)
A dental abscess is a pus-filled infection around the tooth root or gums.
Symptoms include:
- Severe throbbing pain
- Swelling in face or jaw
- Fever
- Bad taste or pus discharge
⚠️ This is a dental emergency.
5. Swollen Gums Behind Back Teeth (Pericoronitis)
If swelling occurs near wisdom teeth, it is often pericoronitis.
This happens when:
- Wisdom teeth partially erupt
- Food and bacteria get trapped
Symptoms:
- Pain while chewing
- Difficulty opening mouth
- Bad breath

6. Hormonal Changes
Hormonal fluctuations during:
- Pregnancy
- Puberty
- Menopause
Can increase gum sensitivity and swelling.
7. Vitamin Deficiency
Deficiency of Vitamin C or B can lead to:
- Weak gums
- Bleeding
- Swelling
8. Medical Conditions and Medications
Conditions like:
- Diabetes
- Immunity disorders
And certain medications can increase gum inflammation.
