A tooth infection is a serious condition that occurs when bacteria invade the innermost layer of the tooth — the dental pulp, which contains nerves and blood vessels.
If left untreated, the infection can spread beyond the tooth, leading to abscesses, intense pain, and even life-threatening complications.
🦠 What Causes a Tooth Infection?
Common causes of a tooth infection include:
- Untreated cavities
- Cracks or trauma in the tooth
- Severe gum disease (periodontitis)
- Previous dental procedures gone wrong
- Poor oral hygiene habits
Once bacteria enter the pulp, the body reacts with inflammation, causing pressure and pain.
⚠️ Symptoms to Watch For
A tooth infection often comes with very noticeable symptoms, such as:
- Throbbing or sharp tooth pain 😣
- Swollen gums or face 😷
- Pain when chewing or biting
- Foul taste or bad breath
- Fever 🤒
- Swollen lymph nodes in the neck or jaw
If the infection spreads, it can affect other areas like the jawbone, sinuses, or even the brain — so early treatment is critical.
🛠️ Treatment Options
Depending on the severity, your dentist may recommend one of the following:
- Antibiotics 💊 – to control the spread of infection
- Root canal treatment 🦷 – to remove infected pulp and preserve the tooth
- Tooth extraction 🪥 – if the tooth is too damaged
- Draining the abscess – to relieve pressure and remove pus
Treatment is often combined with pain management and oral hygiene guidance.
🧼 Aftercare and Recovery
To ensure proper healing, follow these recovery tips:
- Take all medications as prescribed
- Rinse with warm salt water
- Avoid hard foods while the area heals
- Use a soft-bristled toothbrush
- Follow up with your dentist as advised
Recovery time varies, but many patients feel better within a few days.
