How to stop a tooth infection at home
Home care can reduce discomfort from a tooth infection, but dental treatment is needed to remove infected tissue or drain the source.
The short answer
You cannot reliably stop a tooth infection at home; rinsing and pain relief may help temporarily while a dentist treats the infected tooth or drains the abscess. Treatment may involve removing decay, root canal treatment, extraction, or drainage depending on the anatomy and severity.
How does an infection spread from inside a tooth?
A tooth infection usually begins when bacteria reach the pulp through decay, a crack, or a defective restoration, then spread through the root canal system into surrounding bone and soft tissue. A gum swelling or facial lump may be an abscess containing inflammatory fluid and bacteria.
What should you do while waiting for dental treatment?
Arrange urgent dental assessment, keep the area clean, rinse gently with warm water, and use suitable pain relief according to its label. Do not pierce the swelling, apply heat to the face, or place chemicals or tablets on the gum, and do not use leftover antibiotics.
Which signs mean a tooth infection needs urgent care?
Contact a dentist promptly for throbbing pain, swelling, pus, fever, a bad taste, or pain when biting. Go to emergency care immediately if swelling affects the eye, neck, swallowing, breathing, or your ability to open the mouth.
What treatment options should you discuss for the infected tooth?
Ask where the infection is located, whether the tooth can be restored, and whether you need drainage, root canal treatment, or extraction. Ask what pain relief is appropriate and how the dentist will check that the infection has resolved.
Frequently asked questions
Can salt water cure a tooth abscess?
A gentle rinse may clean the mouth and soothe tissue, but it cannot eliminate infection inside the tooth or surrounding tissues.
Will antibiotics fix the infected tooth?
Antibiotics may be considered in selected situations, but they do not replace dental treatment that removes the infected source.
