Tooth pain deserves a clear next step.
Clinically reviewed by Dr. Michael Issakharian, DDS
Severe, persistent, or worsening tooth pain needs dental assessment. Pain with swelling, fever, an injury, or difficulty biting should be reported promptly. The feeling alone cannot tell you whether you need a filling, root canal, or another treatment.

Medical emergency? Call 911 for trouble breathing, uncontrolled bleeding, or a life-threatening injury. Difficulty swallowing or swelling spreading toward the eye or neck needs emergency medical care. Do not wait for a dental appointment.
Why does a tooth hurt?
Toothache can interrupt a meal, a workday, or a night of sleep. Your dentist needs to identify the source before choosing treatment. If you are looking for emergency dental service in Los Angeles, call Cal Dental Group at 323-934-2804 and describe how the pain is affecting you.
Seven possible causes to discuss with your dentist
- Tooth decay: Damage can expose sensitive tooth structure or reach tissue inside the tooth.
- A crack or injury: Pain may occur when biting or releasing pressure. See our broken tooth guide.
- Inflamed or infected pulp: The soft tissue inside a tooth may need treatment when irritation cannot resolve.
- An abscess or gum infection: New swelling, drainage, or a bad taste needs attention. Read about tooth abscess symptoms.
- A loose filling or damaged crown: A change around an old restoration can expose the tooth or affect your bite.
- Grinding or clenching: These can contribute to soreness, wear, and cracks; the dentist checks for other causes too.
- Wisdom-tooth or surrounding-gum problems: Pain at the back of the mouth needs an examination; removal is not automatically the answer.
Several problems can feel similar. A short burst of sensitivity, lingering temperature pain, and spontaneous aching are useful details to report, not diagnoses you need to make at home.
What to tell the office
Identify the side of your mouth, when the pain started, whether it wakes you, and what makes it worse. Mention recent dental work, swelling, fever, allergies, medicines, and any pain medicine already taken. If symptoms change while you wait, contact the team again.
Comfort measures are temporary
Gently clean around the tooth and avoid chewing on a painful area. Do not place aspirin on your gum. Ask a pharmacist or clinician whether an over-the-counter pain medicine is suitable for you and follow its label. Do not use leftover antibiotics or home remedies to try to cure an infection.
What the visit may involve
The dentist reviews your history, examines your mouth, and may recommend X-rays or tests of the affected tooth. Ask what the findings mean and whether the first visit addresses the cause or is an initial stabilization step. Root canal therapy is one possible treatment for selected problems inside a tooth, not a treatment every toothache requires.

Questions about tooth pain
Can a toothache disappear even if something is wrong?
Yes. Changing pain does not reliably show whether the underlying problem has resolved. Keep your appointment and report any swelling or other new symptoms.
Does severe tooth pain always mean extraction?
No. Treatment depends on the examination and whether the tooth can be restored. Discuss the findings, alternatives, and follow-up before deciding.
Can I wait until my next cleaning?
Call the office first if pain is ongoing or affecting normal activities. A routine cleaning appointment may not provide the evaluation your symptoms need.
