Are you experiencing persistent tooth pain or discomfort? You might be dealing with a tooth infection. At Hernandez Dental & Implant Center, we aim to provide clear, simple information about dental abscesses so San Antonio residents can recognize symptoms early and find effective treatment quickly.
What Is a Tooth Infection?
A tooth infection, also called a dental abscess, happens when bacteria enter the pulp inside your tooth through a cavity, crack, or injury. As a result, this infection causes inflammation, swelling, and pain. If left untreated, however, the disease can spread beyond your tooth and cause serious health issues, including jawbone damage and systemic infections that affect other parts of your body.
The pulp chamber inside your tooth contains nerves, blood vessels, and connective tissue. When harmful bacteria reach this sensitive area, your body’s immune system responds with inflammation. Subsequently, pus accumulates in the infected area, creating pressure that causes the characteristic throbbing pain associated with dental abscesses.

Common Symptoms to Watch For

Knowing the signs of a dental abscess helps you get treatment sooner. In particular, common symptoms include:
- Persistent or throbbing toothache, often worse when lying down
- Sensitivity to hot, cold, or sweet foods
- Swollen, red, or tender gums near the affected tooth
- A bump or pimple-like abscess on the gums
- Bad taste or foul odor in your mouth
- Discoloration or darkening of the tooth
- Pain when chewing or biting
- Swelling in your face, cheek, or neck
- Tender or swollen lymph nodes under your jaw
If you notice these signs, don’t hesitate to schedule an exam with your San Antonio dentist to prevent the infection from worsening and protect your smile.
What Causes Dental Abscesses?
Understanding the causes of infections helps you take preventive measures. Specifically, common causes include:
Untreated Cavities: Tooth decay that penetrates deep into the tooth allows bacteria to reach the pulp chamber, consequently creating an ideal environment for infection to develop.
Cracked or Broken Teeth: Trauma from accidents, sports injuries, or biting hard objects can crack teeth, thereby providing entry points for bacteria.
Gum Disease: Advanced periodontal disease creates pockets between teeth and gums where bacteria accumulate, potentially leading to abscesses at the root level.
Previous Dental Work: While rare, complications from dental procedures or failing dental work can sometimes allow bacteria to enter the tooth.
Weakened Immune System: Additionally, people with compromised immunity are more susceptible to developing infections from minor dental issues.
Wisdom Tooth Infection
Wisdom teeth often cause infections because they can be difficult to clean properly or may become impacted. Notably, an infection in the wisdom teeth area can lead to jaw pain, swelling, bad breath, and difficulty opening your mouth. Therefore, it’s important to recognize these symptoms early.
However, not all wisdom teeth require removal. In fact, understanding the benefits of keeping wisdom teeth, such as maintaining jaw strength and proper tooth alignment, is important. Ultimately, your personal dental health will determine if treatment or removal is needed, especially when dealing with an infection. Furthermore, regular checkups allow your San Antonio dentist to monitor your wisdom teeth health and decide the best approach for you.
Treatment Options
Treating a dental abscess promptly is essential to prevent complications. Generally, common treatments include:
Antibiotics: First, your dentist may prescribe antibiotics to fight the bacterial infection and prevent it from spreading. Common antibiotics include amoxicillin, penicillin, or clindamycin for patients with penicillin allergies.
Root Canal Therapy: This procedure removes infected pulp, cleans the tooth’s interior, and seals it to prevent future infections. Importantly, root canals allow you to save your natural tooth rather than extracting it.
Drainage: In some cases, your dentist may need to drain the abscess by making a small incision in the swollen area, relieving pressure, and removing pus.
Tooth Extraction: If the tooth is severely damaged and cannot be saved, extraction may be necessary. Afterward, your dentist will discuss replacement options like dental implants or bridges.
Your dentist will recommend the best option for your specific case. For more detailed information, you can visit our page on [Tooth Root Canal Infection: Symptoms, Treatment, and Prevention].
Managing Discomfort at Home
While visiting your dentist is necessary, here are steps you can take at home to manage discomfort:
- First, gently rinse your mouth with warm salt water several times a day to reduce bacteria and soothe inflamed tissues
- Next, take over-the-counter pain medication like ibuprofen or acetaminophen as directed on the package
- Additionally, avoid very hot, cold, or sugary foods that might irritate the infected tooth
- Meanwhile, maintain oral hygiene by brushing and flossing carefully around the affected area
- Also, apply a cold compress to the outside of your cheek for 15-minute intervals to reduce swelling
- Finally, sleep with your head elevated to minimize pressure and throbbing
These methods help ease symptoms, but remember, they do not replace professional dental care. Instead, home remedies provide temporary relief while you arrange to see your dentist.
Warning Signs You Should Never Ignore
Watch for signs that the infection might be spreading or worsening, such as:
- Increased swelling and severe pain that doesn’t respond to over-the-counter medication
- High fever or chills indicate the infection may be spreading systemically
- Pus or discharge at the infection site with increasing amounts
- Difficulty swallowing or breathing, which may indicate swelling affecting your airway
- Severe headache or neck stiffness
- Rapid heart rate or feeling generally unwell
If you experience any of these symptoms, seek immediate care at an emergency room or contact your dentist right away. For infections related to recent tooth extraction, detailed guidance is available at [Infection After A Tooth Extraction: Painful Signs You Shouldn’t Ignore].
Preventing Dental Infections in San Antonio
Prevention is always better than treatment. Therefore, follow these practices to maintain optimal oral health:
Brush Twice Daily: Use fluoride toothpaste and brush for two minutes, paying attention to all tooth surfaces and the gumline.
Floss Daily: Remove plaque and food particles between teeth where your toothbrush can’t reach.
Regular Dental Visits: Schedule checkups and cleanings every six months so your dentist can catch and treat problems early.
Healthy Diet: Limit sugary and acidic foods that contribute to tooth decay. Instead, choose water over sugary drinks.
Protect Your Teeth: Wear a mouthguard during sports and avoid using your teeth as tools to open packages.
Address Dental Issues Promptly: Don’t ignore toothaches, sensitivity, or other dental symptoms. After all, early treatment prevents minor problems from becoming serious infections.
