How can i stop a bad toothache
A bad toothache needs prompt dental assessment; temporary relief can help while the dentist treats decay, pulp disease, a crack, or infection.
The short answer
You may temporarily reduce a bad toothache with suitable pain relief, gentle cleaning, and a cool compress, but stopping it permanently requires treatment of the dental cause.

What is the direct answer?
What does this question mean?
Severe toothache often means that inflammation is affecting the pulp or tissues around the root, although a cracked tooth or exposed dentin can also hurt. Pain that lingers after cold, starts spontaneously, or worsens when lying down is useful information for diagnosis.
What can you do next?
Clean gently around the tooth, avoid very hot or cold foods, and use a cold pack outside the cheek for short periods if swelling or soreness is present. Follow the label for any suitable pain medicine and never place heat, alcohol, or tablets directly on the gum.
When should you seek dental care?
Contact a dentist promptly when pain is severe, lasts beyond a brief episode, or interferes with sleep or eating. Facial swelling, fever, pus, or difficulty opening the mouth, swallowing, or breathing raises the urgency.
What should you ask the dentist?
Ask whether the tooth needs a filling, root canal treatment, drainage, extraction, or gum care, and what the examination or X-ray shows. Ask how to protect the tooth until treatment and which symptoms require immediate contact.
Frequently asked questions
Why is my toothache worse at night?
Lying down, changes in pressure, and fewer distractions can make inflamed dental pain feel more intense, but the cause still needs assessment.
Can I wait if the toothache stops?
Pain can stop while decay, pulp damage, or infection remains, so a recurring or severe toothache should still be examined.
