Can a Tooth Infection Cause Tingling in Hands and Feet?

A tooth infection happens when bacteria enter the tooth, usually through a deep cavity, crack, or gum disease. While most symptoms are felt in the mouth — like tooth pain, swelling, or sensitivity — some people wonder if a tooth infection can also cause tingling in the hands and feet.

Tooth Infection and Nerve Symptoms

A tooth infection itself usually does not directly cause tingling in the hands or feet. Tingling (also called paresthesia) often comes from nerve irritation or circulation problems, which are unrelated to most dental infections.

However, in rare cases, if a severe untreated infection spreads, it may cause:

• Nerve compression near the jaw or face (leading to numbness or tingling in the mouth, lips, or jaw).

• Systemic infection (sepsis) that affects the whole body and could cause unusual symptoms, including weakness, fever, or nerve-related issues.

More Common Causes of Tingling in Hands and Feet

If you are feeling tingling, it may be due to other reasons, such as:

• Diabetes or blood sugar issues

• Vitamin deficiencies (like B12)

• Pinched nerves in the neck or back

• Poor circulation

• Peripheral neuropathy

When to Seek Help

• If you have a tooth infection with swelling, severe pain, fever, or spreading redness, you should seek dental care right away.

• If tingling in your hands and feet is persistent, you should consult a doctor, as it is likely related to another health issue.

Conclusion
A tooth infection usually does not cause tingling in the hands and feet. While dental infections can affect nearby nerves in the face, tingling in the extremities is more likely caused by other medical conditions. It’s important to address both problems with the right healthcare professional — a dentist for the infection and a doctor for ongoing tingling.
