Tooth infection how to treat
A tooth infection needs dental treatment to remove infected tissue, drain pus, or remove the tooth; antibiotics alone may not eliminate the source.
The short answer
A tooth infection needs dental treatment to remove infected tissue, drain pus, or remove the tooth; antibiotics alone may not eliminate the source. Removing the source is the part that prevents the infection from returning.
How can bacteria spread from decay into tissues around a root?
Bacteria can enter through decay, a crack, or a deep filling and inflame the pulp before infection spreads into tissues around the root. Removing the source is the part that prevents the infection from returning.
What dental treatment might be needed for a tooth infection?
A dentist may examine the tooth, test pulp response, take a radiograph, drain the infection, perform root-canal treatment, or extract the tooth; antibiotics are considered when infection has spread or systemic signs are present. Removing the source is the part that prevents the infection from returning.
Which symptoms make a tooth infection an urgent problem?
Seek urgent care for facial swelling, fever, spreading redness, difficulty opening the mouth, swallowing, or breathing. Removing the source is the part that prevents the infection from returning.
How will the dentist choose the right infection treatment?
Ask where the infection is, whether the tooth can be restored, and why drainage, root-canal treatment, extraction, or medicine is recommended. Removing the source is the part that prevents the infection from returning.
Frequently asked questions
Can home care fix the underlying cause?
It may reduce irritation, but a dental examination is needed when decay, calculus, infection, or a damaged restoration may be present.
What changes make this more urgent?
Increasing pain, swelling, fever, pus, or difficulty swallowing or breathing calls for prompt assessment.
