How to get your mouth to stop hurting
Mouth pain may come from a tooth, gum, jaw, or oral tissue; gentle care can help briefly, but persistent or severe pain needs an exam.
The short answer
Rinse gently with lukewarm water, keep brushing carefully, avoid foods that trigger the pain, and use an over-the-counter pain medicine only as directed on its label. Arrange a dental examination promptly if the pain persists, returns, or comes with swelling, fever, pus, injury, or trouble swallowing.

What is the direct answer?
What does this question mean?
Mouth pain can arise from a cavity reaching the dentine or pulp, an inflamed gum, a cracked tooth, a trapped food particle, an ulcer, irritation from a denture or sharp tooth edge, or strain in the jaw muscles or temporomandibular joint. The location, trigger, duration, and presence of swelling help a dentist identify which tissue is involved.
What can you do next?
Rinse with lukewarm water and gently remove food caught between teeth with floss or an interdental brush. Continue gentle brushing with a soft-bristled toothbrush, choose soft foods, chew on the opposite side, and avoid very hot, cold, sweet, acidic, or spicy foods if they worsen the pain. Do not place aspirin or another tablet directly on the gum because it can injure the tissue.
At the examination, the dentist may inspect the teeth and oral lining, test sensitivity to cold or tapping, check the gums and bite, and take a dental X-ray when the findings suggest decay, a crack, infection, or bone involvement. Treatment depends on the cause and may include removing decay and placing a filling, cleaning infected gum tissue, repairing a damaged tooth, root canal treatment, or removing a tooth that cannot be restored.
When should you seek dental care?
Seek urgent dental care for facial or gum swelling, fever, pus or a bad taste from a tooth, rapidly worsening pain, a knocked-out or broken tooth, or difficulty opening the mouth. Go to emergency medical care if swelling makes breathing or swallowing difficult, or if swelling is spreading toward the eye or neck.
Book a dental visit when pain lasts beyond a short episode, wakes you at night, keeps returning, or is triggered by biting or hot and cold drinks. Pain medicine can reduce the symptom while the cause remains, so relief alone does not show that the tooth or gum has healed.
What should you ask the dentist?
Ask which tooth or tissue is causing the pain, whether the pulp or gum is involved, and what examination or X-ray finding supports that conclusion. Ask which treatment can keep the tooth, what symptoms should prompt an urgent return, and how to manage eating, brushing, and pain medicine while treatment is arranged.
Frequently asked questions
Can mouth pain go away without treatment?
A minor irritation may settle, but pain from decay, a crack, pulp inflammation, or an abscess usually needs dental treatment even if it temporarily improves.
What if the pain is coming from a mouth ulcer?
Avoid rubbing or irritating the ulcer, choose softer foods, and have it examined if it is unusually painful, keeps returning, or does not heal.
Should I use pain medicine for mouth pain?
Use only a medicine suitable for you and follow the package directions; ask a pharmacist or clinician if you have another condition, take other medicines, or are pregnant.
