Tooth infections can make us downright miserable. The constant pain, swelling, and the throbbing that never seems to stop is enough to make anyone desperate for relief.
In this guide, we’ll recommend some of the strongest natural antibiotic that have been used for centuries to fight tooth infection, reduce inflammation, and soothe discomfort. But remember, these remedies are not cures—they’re a stopgap to help you manage the symptoms until you can get to your dentist.
Natural remedies can provide some temporary relief in the meantime, but it’s critical to see a dentist for professional care as soon as possible.
The Common Causes of Tooth Infection
Before diving into natural remedies, it’s important to understand that tooth infections don’t just happen overnight. They are the result of poor oral hygiene or neglected dental problems that have gone unchecked. Here are some of the most common causes:
- Cavities: One of the most common causes of tooth infections is untreated cavities. When cavities aren’t filled, bacteria can invade the inner layers of the tooth, leading to an infection.
- Gum Disease (gingivitis or periodontitis): Infected or inflamed gums can cause the gums to recede, leaving the tooth’s root exposed and vulnerable to infection. If not treated, it can lead to abscesses and severe pain.
- Previous Dental Work: If you’ve had a filling or crown in the past, these areas can be more susceptible to infection if not properly cared for.
- Trauma: A cracked or chipped tooth can expose the inside of the tooth to bacteria, causing an infection.
- Poor Diet and Smoking: A diet high in sugary foods and drinks, combined with smoking, can increase the chances of developing tooth infections by weakening the body’s immune system and encouraging bacterial growth.
Symptoms of a Tooth Infection
- Throbbing pain in or around the tooth
- Swelling in the face or neck
- Fever and chills
- A bad taste in your mouth or foul-smelling breath
- Sensitivity to hot and cold temperatures
- Pus or drainage around the tooth or gum area
How a Tooth Infection Ended up in Chronic Fatigue and Brain Fog
John, a 38-year-old man, had been struggling with intense fatigue and brain fog for years. Despite undergoing numerous tests with multiple specialists, he couldn’t find any clear answers. His heart was fine, his blood tests showed no abnormalities, and he didn’t have conditions like Epstein-Barr or sleep apnea.
After years of trying to figure out the cause of his symptoms, John visited an oral surgeon who made a surprising discovery: a longstanding infected tooth that had been left untreated for years. The oral surgeon explained that the infection had essentially “burned through” the tooth and was draining into his bloodstream. Thankfully, the infection hadn’t reached his sinus cavity yet, but it was still wreaking havoc on his health.
The surgeon explained that the bacteria in the infected tooth were producing neurotoxic toxins that could potentially explain John’s chronic fatigue and brain fog. This was a major revelation for John—his GP had run numerous tests, but never pointed to an infection. His white blood cell count and other markers were normal, and he had never noticed a change in his symptoms when prescribed antibiotics for unrelated conditions.
Now, with the surgery scheduled to remove the infected tooth, the oral surgeon was optimistic that John would start feeling much better—potentially even “like new.” John is hopeful, but also cautious, as he’s aware that recovery might take time and that his fatigue and brain fog may not vanish immediately after the surgery.
While these dental abscesses, can be extremely painful, it’s important to remember that they can be prevented or treated with prompt care.

How Do These Natural Remedies Actually Work?
Can garlic, cloves, or oil pulling really help you with a tooth infection? Natural antibiotics and remedies for tooth infections don’t work by magic—they rely on science.
While many natural remedies have been used for centuries, it’s only in recent years that scientists have caught up to explain why they are so effective in combating tooth infections. Let’s understand the chemistry and biology behind the most common active ingredients, so you can feel more confident about using them:
- Allicin, present in garlic, is a powerful compound with antibacterial properties. Allicin disrupts bacterial cell membranes, killing harmful bacteria and preventing infection. Studies have shown it can fight oral pathogens and promote healing in the mouth.
- Eugenol present in clove oil has pain-relieving and antibacterial effects. It numbs the pain and reduces inflammation, while also fighting bacteria in the infected area. Eugenol has been shown to inhibit oral pathogens and help heal gum tissue.
- Carvacrol, present in oregano oil, is a compound that targets bacterial cell walls, breaking them down. This helps eliminate harmful bacteria causing toothache while also reducing gum inflammation. Carvacrol is particularly effective against bacteria like Streptococcus mutans.
- Curcumin in turmeric has strong anti-inflammatory properties that help reduce gum swelling and pain. It blocks inflammatory molecules and promotes healing. Research has shown that curcumin can improve oral health and reduce infection symptoms.
- Eugenol and menthol in peppermint oil fight infection and relieve pain. Menthol provides a cooling sensation that numbs the pain, while eugenol fights bacteria and reduces inflammation in the gums, making it an effective remedy for tooth infections.
- Acetic acid in apple cider vinegar helps balance the mouth’s pH and prevents bacteria from thriving. Its acidity neutralizes harmful microbes, reducing the risk of further infection. However, it should be diluted to protect tooth enamel from damage.
What to Do When Natural Remedies Aren’t Enough
Natural cures aren’t a permanent solution. There are limits to what these treatments can do.
If the pain becomes unbearable or if the swelling spreads to your face or neck, it could be a sign of a more serious infection, such as an abscess. At this point, it’s time to get professional care to drain the infection and possibly prescribe antibiotics.
If you have a fever is your body’s way of telling you that an infection has spread beyond the tooth and may be affecting your body systemically. This is a clear sign that the infection needs to be addressed by a dentist or doctor.
Natural remedies may reduce pain and inflammation, but only a dentist can fully treat the infection, whether through antibiotics, drainage, or more advanced dental treatments.
