Tooth infections are more than just a painful inconvenience, they can impact your overall health when left untreated. While many people associate tooth infections with obvious pain or swelling, not all infections start that way. Understanding how infections begin, how they spread, and when to see a dentist can help you take proactive steps to protect your oral health.
Let’s take a closer look at what a tooth infection is, how it develops, and what you can do to stop it from getting worse.
What Is a Tooth Infection?
A tooth infection occurs when bacteria enter the pulp, the soft inner part of the tooth that contains nerves and blood vessels. This typically happens when a cavity or crack in the tooth goes untreated, giving bacteria a pathway into the deeper layers. Once inside, the infection can cause inflammation, pus buildup (abscess), and pressure that leads to pain.
Although tooth infections often begin locally, they have the potential to spread if not addressed. This is why early care and diagnosis are so important.
How Do Tooth Infections Start?
Tooth infections can start in a few different ways:
- Untreated cavities: When tooth decay is allowed to progress, it can eat through the enamel and dentin, reaching the pulp.
- Cracks or chips: Damage to the tooth surface can expose the pulp to bacteria, even if you don’t feel pain at first.
- Gum disease: Infections of the gums can sometimes travel down to the root of the tooth, especially if there’s significant gum recession or bone loss.
- Failed dental work: Occasionally, a filling or crown may loosen over time, creating gaps where bacteria can enter.
When bacteria reach the inner part of the tooth, the immune system responds by sending white blood cells to fight the infection, which can result in swelling and the buildup of pus.
Common Signs of a Tooth Infection
Not every infected tooth is immediately painful, but there are warning signs that should prompt a visit to the dentist:
- Persistent or severe toothache
- Throbbing or radiating pain in the jaw, ear, or neck
- Sensitivity to hot or cold
- Swelling in the gums, face, or jaw
- A bad taste in the mouth or persistent bad breath
- A pimple-like bump on the gum (dental abscess)
- Fever or general feeling of being unwell (in more advanced cases)
Even if symptoms are mild, it’s worth getting checked out. An early-stage infection is much easier to treat than one that has spread.
How Tooth Infections Can Spread
A tooth infection doesn’t always stay confined to the tooth. Over time, if the infection is not treated, it can extend beyond the root of the tooth into nearby areas, such as:
1. The Jawbone
Infections can spread into the bone that holds the teeth in place. This may lead to bone loss, pain, and difficulty chewing.
2. The Sinuses
Upper back teeth are close to the sinus cavities. Infections in these teeth can potentially cause sinus pressure, congestion, or even a sinus infection.
3. The Soft Tissues of the Face or Neck
If an abscess ruptures or continues to grow, it can spread into the soft tissue of the cheeks, tongue, or neck. This may result in visible swelling, difficulty swallowing, or limited jaw movement.
4. The Bloodstream (Rare Cases)
In very rare and severe cases, an untreated infection may enter the bloodstream, leading to a condition known as sepsis. While uncommon, this highlights the importance of not delaying treatment.
What to Expect from Treatment
If you have a tooth infection, your dentist will determine the best course of action based on how far the infection has progressed. Common treatment options include:
- Root canal therapy: If the infection is limited to the tooth, a root canal removes the infected pulp and seals the tooth to prevent reinfection.
- Antibiotics: These may be prescribed if the infection has spread or there’s swelling, but they’re usually a temporary measure, not a replacement for treating the source.
- Tooth extraction: If the tooth is too damaged to save, removing it may be the best option to stop the spread of infection.
- Drainage of abscess: In some cases, the dentist may need to make a small incision to drain the infection if a pocket of pus has formed.
After treatment, your dentist may recommend follow-up visits to monitor healing and ensure that the infection doesn’t return.
How to Prevent Tooth Infections
The best way to avoid a dental infection is through prevention and regular care:
- Brush twice a day with fluoride toothpaste
- Floss daily to remove plaque between teeth and below the gumline
- Avoid frequent sugary snacks and drinks
- Visit your dentist regularly for exams and cleanings
- Address cavities, cracks, or gum disease early, before they become serious
Small issues can become bigger ones over time. By maintaining your dental health, you reduce the risk of infection and improve your overall well-being.
When to See a Dentist
Not every toothache is an emergency, but if you notice any of the following, it’s time to call your dentist:
- Pain that doesn’t go away
- Swelling around your face, gums, or jaw
- A bump or pimple near the base of your tooth
- A broken or chipped tooth with sensitivity or discomfort
- Fever or signs of infection alongside tooth pain
Your dentist can evaluate whether the problem is minor or requires more urgent care. Acting early helps avoid complications and protects your comfort and oral health.
