Swollen gums are a common dental concern, but you shouldn’t ignore them. Healthy gums should generally feel firm and fit closely around the teeth.
When gums become puffy, enlarged, red, tender, or painful, it can signal irritation or inflammation. Identifying the underlying cause is important because persistent gum swelling can sometimes be an early sign of gum disease or another dental problem.
What Causes Swollen Gums?
Swollen gums can develop for many different reasons. Plaque buildup and gingivitis are among the most common, but dental infections, trapped food, hormonal changes, medications, and other conditions can also contribute.
1. Gingivitis and Plaque Buildup
One of the most common causes of swollen gums is gingivitis, which is the beginning stage of gum disease.
Plaque is a sticky film containing bacteria that constantly forms on the teeth. If it is not removed adequately through brushing and cleaning between the teeth, it can irritate the gum tissue.
This may cause gums to become:
- Red
- Puffy or swollen
- Tender
- More likely to bleed during brushing or flossing
However, gingivitis can often be reversed with improved oral hygiene and professional dental cleaning.
2. Periodontitis
If gingivitis is not treated early on, it can progress to periodontitis, a more advanced form of gum disease.
Periodontitis affects the tissues and bone that support the teeth. In addition to swollen gums, patients may notice gum recession, persistent bad breath, loose teeth, or changes in the way their teeth fit together.
Because periodontitis can permanently damage the structures that support the teeth, professional treatment is important.
3. Food Trapped Between the Teeth
Sometimes swelling is concentrated around one particular tooth. A common reason is food becoming trapped between the teeth or underneath the gumline.
Popcorn hulls, seeds, meat fibres, and other small food particles can irritate the gums. The resulting inflammation may cause localized swelling and discomfort.
Carefully cleaning between the teeth with floss or an interdental cleaner may help. If the swelling persists, a dental examination can determine whether there is another underlying problem.
4. Dental Abscess or Infection
A swollen area around a particular tooth can sometimes indicate a dental infection.
A dental abscess can develop when bacteria enter the inner portion of a tooth or infect the surrounding gum tissue.
Symptoms may include:
- Significant pain
- Swelling around a tooth
- Sensitivity
- A bad taste or drainage
- Fever in more serious cases
Dental infections require professional treatment and should not be left untreated. Infections can spread beyond the original area if they are not properly managed.
5. Wisdom Teeth
Partially erupted wisdom teeth are another frequent cause of swollen gums.
When a wisdom tooth does not fully erupt into the mouth, a flap of gum tissue can remain over part of the tooth. Leftover food and bacteria can become trapped underneath this tissue, resulting in inflammation or infection.
This condition is known as pericoronitis and commonly affects the lower wisdom teeth.
6. Hormonal Changes
Fluctuations in hormones can make gum tissue more sensitive to plaque and bacteria.
Pregnancy, puberty, menstruation, and menopause can all be associated with changes in gum health. During pregnancy, for example, increased sensitivity to plaque can cause gums to swell, become red, and become more prone to bleeding.
Maintaining good oral hygiene and attending regular dental appointments can help manage these changes.
7. Certain Medications
Some medications can affect the gums or contribute to oral health problems.
Certain drugs may cause dry mouth, which reduces saliva’s protective effects and can increase plaque buildup. Other medications can enlarge gum tissue.
If you notice significant changes in your gums after starting a medication, discuss the symptoms with your dentist and healthcare provider. Do not stop taking prescribed medication without professional advice.
8. Poor Oral Hygiene
Inadequate brushing and cleaning between the teeth allows plaque to accumulate. Over time, this can irritate the gums and cause inflammation.
Brushing twice a day with fluoride toothpaste and flossing between the teeth daily are important steps for preventing plaque-related gum problems.
9. Aggressive Brushing
Swollen or irritated gums are not always caused by brushing too little. Brushing too aggressively can also traumatize the gum tissue.
Using excessive pressure or a hard-bristled toothbrush may cause soreness, irritation, and eventually gum recession.
A soft-bristled toothbrush and gentle technique are generally recommended.
10. Poorly Fitting Dental Appliances
Dental appliances or restorations that do not fit properly can sometimes irritate the surrounding gums.
Examples may include:
- Dentures
- Dental crowns
- Dental Bridges
- Orthodontic appliances
If swelling develops around a restoration or appliance, your dentist can determine whether an adjustment is necessary.
What Can You Do About Swollen Gums?
Dental treatment depends on the cause of the swelling.
For mild inflammation caused by plaque buildup, improving brushing and interdental cleaning may help. A professional dental cleaning may also be necessary if tartar has accumulated.
Other causes may require specific treatment. A dental infection, for example, may require treatment of the affected tooth, while advanced gum disease may require periodontal therapy.
Don’t rely solely on home remedies if swelling is persistent or severe.
When Should You See a Dentist?
You should arrange a dental examination if swollen gums:
- Last longer than several days
- Keep returning
- Bleed frequently
- Are accompanied by persistent bad breath
- Occur around a painful tooth.
- Are associated with loose teeth
- Cause significant discomfort
Seek urgent dental or medical attention if gum swelling is accompanied by facial swelling, difficulty breathing or swallowing, fever, or rapidly increasing pain.
How Can Swollen Gums Be Prevented?
Good daily oral hygiene is one of the most impactful ways to reduce the risk of gum inflammation.
Helpful habits include:
- Brush twice a day with fluoride toothpaste.
- Clean between your teeth every day.
- Use a soft-bristled toothbrush.
- Avoid brushing with excessive pressure.
- Attend regular dental examinations and cleanings.
- Avoid smoking and tobacco products.
- Maintain a balanced diet.
- Stay hydrated
Regular dental visits can also identify the beginning signs of gingivitis before they become more serious.
Frequently Asked Questions About Swollen Gums
Why are my gums swollen around one tooth?
Swelling around one tooth may be caused by trapped food, localized gum inflammation, tooth decay, an infection, or an issue involving the tooth’s root. If the swelling doesn’t resolve, a dentist should examine it.
Can swollen gums go away on their own?
Mild gum inflammation caused by plaque may improve with better oral hygiene. However, persistent or worsening swelling may indicate an underlying dental problem that requires professional treatment.
Can flossing help swollen gums?
Yes. Cleaning between the teeth helps remove plaque and food particles that can contribute to gum inflammation. However, a dental professional should still evaluate persistent swelling.
