Causes, Symptoms, and Treatments

December 14, 2024 Written By: Joyce Kahng, DDS

Highlights:

  • Swollen gums around one tooth often result from poor oral hygiene, trapped food debris, or gum disease like gingivitis or periodontitis.
  • More serious causes include a dental abscess or wisdom tooth eruption/impaction, which may require professional treatment.
  • Symptoms to watch for include redness, tenderness, bleeding, and in severe cases, pus discharge or fever, indicating infection.
  • Simple home remedies like warm saltwater rinses, cold compresses, and proper flossing can help reduce mild swelling.
  • Persistent swelling or severe pain should be evaluated by a dentist for treatments like scaling, abscess drainage, or wisdom tooth extraction.
  • Prevention also involves avoiding tobacco and maintaining a balanced diet to support gum health.

What Causes Gum Swelling Around One Tooth?

When it comes to gum swelling around one tooth, there are a few common culprits to consider.

Poor Oral Hygiene: Plaque Buildup and Tartar

Gum swelling is a common issue, often caused by poor oral hygiene. It usually starts with bacteria building up in your mouth, forming a sticky layer known as plaque.

If plaque isn’t removed through regular brushing and flossing, it hardens into tartar, which can irritate your gums and lead to swelling or tenderness. 

Food Trapped Between Teeth

Gum swelling around one tooth is often caused by food particles getting stuck between your teeth. These trapped bits of food can create an ideal environment for bacteria to thrive, leading to inflammation and discomfort.

This issue is particularly common in areas that are harder to clean, like around your molars. Proper flossing or brushing in these spots can be tricky, making them more prone to problems. 

Gum Disease (Gingivitis and Periodontitis)

Gum disease, also called gingivitis in its early stages or periodontitis in advanced cases, is a condition that affects the gums and the structures supporting the teeth. It often begins with mild symptoms that may go unnoticed.

  • Early signs include mild inflammation and swelling around one or more teeth. At this stage, the condition is usually painless but requires attention to prevent progression.
  • If untreated, gum disease can lead to more severe complications such as gum recession, tooth loss, and even bone damage.

Advanced gum disease results in severe inflammation, which can impact not only oral health but overall well-being. Recognizing and addressing the issue early is key to avoiding these outcomes.

Dental Abscess

A dental abscess is a painful infection that develops near the root or gum of a tooth. It is often caused by deep tooth decay, trauma, or gum disease, leading to swelling and tenderness.

Common symptoms of a dental abscess include: 

  • Throbbing pain around the affected tooth 
  • The presence of pus in the area 
  • Persistent bad breath

If you suspect an abscess, it’s important to act quickly. Prompt dental treatment is essential to prevent further complications and manage the infection effectively.

Wisdom Tooth Eruption or Impaction

Wisdom tooth eruption or impaction can sometimes cause swelling near the root or gum of a tooth. This often happens when wisdom teeth only partially erupt or become impacted, creating potential issues.

  • Pericoronitis is a common condition linked to partially erupted wisdom teeth. It occurs when bacteria and debris get stuck between the tooth and gum, leading to inflammation and discomfort.

If you’re noticing swelling or tenderness around your wisdom teeth, it’s a sign that something may be wrong.

Other Causes

Swelling and tenderness near a tooth can stem from a variety of causes. Deep tooth decay, gum disease, or trauma are common culprits. Trauma, such as an accidental impact or even an injury from a toothbrush, can lead to inflammation and discomfort.

In some cases, allergic reactions to dental materials used in procedures may also result in localized swelling. It’s important to pay attention to these symptoms as they could indicate an underlying issue.

Symptoms to Watch For

When it comes to dental health, paying attention to symptoms can help identify potential issues early on. Here are some common symptoms to watch for:

  • Redness, tenderness, and swelling around one tooth: Notice any unusual redness, tenderness, or swelling around a specific tooth? It could be a sign of an underlying problem that needs attention.
  • Pain when chewing or brushing: Experiencing pain or discomfort when biting down on food or brushing your teeth? This could indicate an issue that requires dental care.
  • Bleeding gums: If your gums bleed while brushing or flossing, it may be a sign of gum disease or other dental concerns.

Persistent dental issues can sometimes signal more serious underlying problems. Ignoring them might lead to complications, so it’s always best to stay cautious.

Watch for warning signs, including: 

  • Swelling 
  • Pus discharge 
  • Fever 
  • Swollen lymph nodes 

These symptoms may indicate a significant dental infection that requires immediate attention. 

Act fast by seeking professional dental care. Quick action is essential to prevent the infection from worsening or leading to further health problems.

How to Treat Swollen Gums Around One Tooth

Home Remedies

If you notice swelling around one tooth, it’s important to take action to address the issue and prevent further complications. Here are some practical tips to help you treat swollen gums:

  1. Warm saltwater rinses: Rinse your mouth with a warm saltwater solution to help reduce inflammation and promote healing. Dissolve half a teaspoon of salt in a glass of warm water and swish it around your mouth for about 30 seconds before spitting it out.
  2. Cold compress to reduce swelling: Applying a cold compress to the affected area can help reduce swelling and provide temporary relief. Wrap an ice pack or a bag of frozen vegetables in a thin cloth and apply it to your cheek for 10-15 minutes at a time.
  3. Over-the-counter pain relief (e.g., ibuprofen): If you’re experiencing discomfort or pain, over-the-counter pain relievers like ibuprofen can help alleviate the symptoms. Follow the instructions on the packaging and consult your healthcare professional if you have any concerns.

It’s important to note that these home remedies can provide temporary relief, but they do not replace professional dental care. If the swelling persists or worsens, it’s essential to seek prompt dental attention. A dentist will be able to diagnose the underlying cause of the swelling and provide appropriate treatment to address the issue effectively.

Professional Dental Treatments

Wisdom Tooth Removal 

When your wisdom teeth start causing problems like pain, infection, or crowding, removal might be necessary. This procedure helps maintain oral health and prevents future complications.

The removal of wisdom teeth is typically a surgical procedure performed under local anesthesia. This ensures a comfortable and stress-free experience for patients.

Why remove wisdom teeth?

  • To alleviate pain or discomfort
  • To prevent infections caused by trapped food or bacteria
  • To avoid overcrowding or damage to nearby teeth

Scaling and Root Planing 

If brushing and flossing aren’t enough to tackle plaque and tartar buildup, scaling and root planing might be the answer. This deep cleaning procedure targets the areas regular cleaning can’t reach.

Here’s how it works: 

  • Removal of buildup: Plaque and tartar are cleared from your teeth. 
  • Smoothing the root surfaces: This step helps prevent future problems like gum disease. 

Scaling and root planing is an effective way to treat gum disease and maintain healthy gums in the long term.

Abscess Drainage 

Infections leading to an abscess in the tooth or gums often require professional treatment to avoid complications.

Your dentist may recommend the following steps: 

  • Drainage of the abscess: This process involves cleaning the infected area and carefully draining the buildup to alleviate pressure and pain. 
  • Antibiotics: These are commonly prescribed to ensure the infection is fully treated and to prevent it from spreading. 

By addressing the root cause and managing the infection effectively, you can restore oral health and avoid further issues.

FAQs About Swollen Gums

Why is my gum swollen only around one tooth?

Swelling around a single tooth can indicate various issues such as an abscess, trapped food particles, or gum infection.

How long should swelling last before seeing a dentist?

If you experience gum swelling that lasts for more than a few days, it’s recommended to schedule an appointment with your dentist.

Can home remedies completely cure swollen gums?

While some home remedies may provide temporary relief, they may not address the underlying cause of swollen gums. It’s essential to consult a dental professional for a comprehensive evaluation and appropriate treatment for long-term resolution.

Is swelling always a sign of gum disease?

Swelling can be a symptom of gum disease, but it can also indicate other dental issues. Only a qualified dentist can accurately diagnose the cause of gum swelling based on a thorough examination and professional assessment.

Can braces or dental devices cause swollen gums?

Braces or dental devices may cause temporary gum irritation and swelling, especially during the initial adjustment period. Proper oral hygiene practices, regular dental check-ups, and communicating any concerns with your orthodontist can help manage and prevent such issues.
