Is Fever After Getting Braces Dangerous? Causes and How to Manage It

Hello, during orthodontic treatment, some patients report having a fever after getting braces, accompanied by fatigue, tooth soreness, or general discomfort, making them concerned about whether this is a dangerous sign. From a medical perspective, I will explain each aspect clearly so that you can understand the situation correctly and avoid unnecessary anxiety.

Is Fever After Getting Braces Dangerous?

My answer is as follows: having a fever after getting braces is not always dangerous, but it should never be ignored, especially if the fever persists or is accompanied by abnormal signs involving the teeth or gums.

Physiologically, during the initial stage of orthodontic treatment or after each adjustment appointment, the body may develop a mild inflammatory response. In some individuals with greater sensitivity, this response may be accompanied by a low-grade fever (usually below 38°C / 100.4°F), which typically resolves on its own within 1–2 days. However, if the fever is high, lasts for several days, or is accompanied by severe swelling, intense pain, gum discharge, bad breath, or similar symptoms, it is no longer considered a normal response and may indicate an infection.

Why Can Braces Cause a Fever?

Fever after getting braces may result from various causes, with the following two being the most common.

Inflammatory Response During Tooth Movement

During orthodontic treatment, the orthodontist applies controlled force to move the teeth within the jawbone. This process triggers a normal inflammatory response in the periodontal ligament and alveolar bone. For most people, this response only causes tooth soreness. However, in patients who have:

• A sensitive constitution
• A weakened immune system
• Recently undergone a stronger-than-usual orthodontic adjustment

the body may respond with a temporary low-grade fever and fatigue. This is generally a self-limiting reaction and is usually not dangerous.

Oral Infection or Poor Oral Hygiene

If oral hygiene is inadequate during orthodontic treatment, plaque and bacteria can easily accumulate around the brackets and archwires. This may lead to:

• Gingivitis or periodontitis
• Dental infection
• A localized gum abscess

In such cases, fever after getting braces may be a warning sign of infection and should be evaluated promptly by your orthodontist.

How to Manage a Fever During Orthodontic Treatment

If you develop a fever while wearing braces, the appropriate management depends on its severity.

If you have a mild fever below 38°C (100.4°F) without significant swelling or severe pain:

• Get adequate rest and drink plenty of water.
• Eat soft foods and avoid heavy chewing.
• You may take a common fever-reducing medication as directed.

If your fever exceeds 38°C (100.4°F), lasts longer than 2 days, or is accompanied by:

• Severe swelling or pain in the gums or face
• Pus, bad breath, or intense pain
• Generalized fatigue

You should visit your orthodontist immediately for evaluation and timely treatment. Do not take antibiotics on your own.

How Can You Prevent Fever During Orthodontic Treatment?

To reduce the risk of developing a fever after getting braces, I recommend that you:

• Maintain excellent oral hygiene using interdental brushes and a water flosser.
• Attend all scheduled follow-up appointments so your orthodontist can properly control the orthodontic forces.
• Inform your orthodontist immediately if you notice unusual pain or swelling.
• Maintain a balanced diet and get adequate rest to strengthen your immune system.

Proper preventive care helps ensure that your orthodontic treatment progresses more comfortably and safely.
