A toothache is pain in or around a tooth. Common causes are cavities, a cracked tooth, gum disease, grinding and infection. Home care such as a warm saltwater rinse and a cold pack may ease mild pain for a short time. A true toothache needs a dentist, and fever, swelling or trouble breathing needs an emergency room. GuideUpdated October 26, 20268 min read 1. 1 ## A true toothache needs a dentist Cleveland Clinic says pain that comes from the tooth itself usually means an issue that needs treatment. 2. 2 ## Home care is short-term Cleveland Clinic says home remedies can offer some mild relief, but pain that does not go away needs a dentist. 3. 3 ## Never put aspirin on the gum The ADA and Cleveland Clinic both warn against placing aspirin on the aching tooth or gum, because it can burn the tissue. 4. 4 ## Know the ER signs Fever over 101 degrees Fahrenheit, swelling below the eye, or trouble breathing or swallowing means an emergency room. ## Why does my tooth hurt? A toothache has many possible causes. Cleveland Clinic lists cavities, an abscessed tooth, a cracked tooth, a damaged filling or crown, teeth grinding and gum disease. Minor aches can also come from gum irritation, such as a seed or popcorn hull stuck under the gum. Only a dentist can tell which cause is yours. Cleveland Clinic says the short answer is that you cannot know for sure until you see a dentist. The pain pattern still gives clues, and it helps you describe the problem when you call. What the pain feels like What it may point to What the dentist may check Dull, constant ache An infected tooth, or grinding at night Exam, X-ray, tap test, bite check Sharp, stabbing pain A [cavity](https://towncenterdental.multisites.ai/glossary/cavity-dental-caries), a crack, or a worn filling or crown Exam and X-ray of that tooth Severe, throbbing pain Infection that has reached the [pulp](https://towncenterdental.multisites.ai/glossary/tooth-pulp) Exam, X-ray, tests of the nerve Pain with hot or cold Cavities, cracks, gum disease or worn enamel Exam, gums, bite Swollen gum or bump on the gum An [abscess](https://towncenterdental.multisites.ai/glossary/dental-abscess) Exam and X-ray right away Aching jaw and teeth in the morning Clenching or [grinding](https://towncenterdental.multisites.ai/glossary/bruxism-teeth-grinding) Exam of tooth wear The rows follow Cleveland Clinic’s descriptions. Treat the table as a way to organize your thoughts, not a diagnosis. Many causes overlap. ## What can you do at home until you are seen? You can ease mild pain for a short time, but home care does not treat the cause. Cleveland Clinic says home remedies can offer some mild relief. If pain does not go away, you need a dentist. Here are steps that fit what the ADA and Cleveland Clinic describe: 1. Rinse with warm water to clean the area. Rinse with warm salt water too: mix 1/2 teaspoon of salt in 8 ounces of warm water, swish, and spit. 2. Gently floss to remove food caught between the teeth. The ADA lists this step. 3. Hold a cold pack or a bag of ice wrapped in a clean towel against the outside of your jaw for about 20 minutes. Repeat several times a day. 4. If you use hydrogen peroxide, never use it pure. Cleveland Clinic says to dilute it with equal parts water, swish, spit and not swallow. 5. Avoid very hot, cold or sweet foods on that side. 6. Call a dentist to book a visit. Do not put aspirin on the tooth or the gum. Both the ADA and Cleveland Clinic warn that it can burn the gum tissue. ## What is safe to take for a toothache? Cleveland Clinic says you can take over-the-counter pain relievers such as acetaminophen or ibuprofen while you wait to see your dentist. Cleveland Clinic’s emergency page also lists naproxen. Read the label and take only the amount it lists. If you have a health condition, take other medicines, are pregnant, or are giving medicine to a child, ask a doctor or pharmacist first. A web guide cannot tell you what is right for your body. Pain relievers and antibiotics have a limit. Cleveland Clinic says their effects are temporary. Even if an infection seems to settle with antibiotics, it comes back unless the underlying problem is treated. ## Does a toothache that stops mean the problem is gone? Not always. Pain can ease for a while even when the cause is still there. Cleveland Clinic says that if you have a cavity or abscess, the pain may come and go somewhat, but it will not go away completely. So a quiet tooth is not proof of a fixed tooth. Pain from gum irritation, such as from biting something hard, is different. Cleveland Clinic says that kind of discomfort will likely pass in a day or two. If a day or two goes by and the pain stays or returns, treat it as a true toothache and book a visit. If pain eases suddenly after being severe, still call. Only an exam can show whether the tooth is fine. ## What about swelling, a bump on the gum, or a bad taste? These signs point toward an abscess. Cleveland Clinic describes abscesses as swollen areas or pimple-like infections that occur around the root of a tooth or in the space between your teeth and gums. It says an abscess is a serious condition that can damage tissue and surrounding teeth. A swollen, painful bump on the gum needs a dental visit soon, and a swollen face needs more urgency. Review the ER signs above. If the swelling is spreading, or you have a fever or trouble breathing or swallowing, do not wait for an appointment. A dentist treats an abscess by treating its source. That may mean a root canal to clean out the infected pulp, or in some cases removing the tooth. Medicine alone is not the full answer, because Cleveland Clinic says the effects of antibiotics and pain relievers are temporary. ## What should you avoid when a tooth hurts? A few habits make things worse. Avoid these: - **Aspirin on the gum.** Both the ADA and Cleveland Clinic warn that it can burn the tissue. - **Sharp tools.** The ADA says that for an object stuck in the mouth, you should gently try floss and not use sharp or pointed instruments. - **Pure hydrogen peroxide.** Cleveland Clinic says never to rinse with it undiluted. - **Waiting out severe pain.** A true toothache usually means a problem that needs treatment. - **Chewing on the sore tooth.** If biting hurts, use the other side until you are seen. Do not skip a dental visit because home care helped. Relief means the pain eased, not that the cause is treated. ## Is a toothache the same as tooth sensitivity? They overlap but are not the same. Sensitivity is a short, sharp reaction to cold, heat or sweets. A toothache is pain that stays, or that comes without a trigger. Sensitivity can also be a warning sign of cavities, cracks or gum disease, per Cleveland Clinic. If your main complaint is a zing from cold drinks, our [sensitive teeth guide](https://towncenterdental.multisites.ai/guides/sensitive-teeth) explains causes and fixes. If pain lingers after the trigger is gone, treat it as a toothache and call. ## What should you ask at the visit? Bring a short list of questions. It helps you leave with a plan you understand. 1. What is causing the pain? 2. What did the exam and X-ray show? 3. What are my options, and what happens if I wait? 4. How many visits will treatment take? 5. What can I take and do at home until then? 6. When should I call back or go to an emergency room? 7. How will fees and insurance work? The practice gives each patient their own estimate. Write the answers down. If you decide to get a second opinion, they will help the next dentist. A dentist starts with questions and an exam. Cleveland Clinic says the dentist will ask about your symptoms and may take an X-ray to see problems beneath the gums. You may be asked when the pain began, what sets it off, how long it lasts, and what makes it better or worse. Tell the team about swelling, a bad taste, fever, or pain that wakes you at night. Bring a list of your medicines. If you can, note whether you grind or clench your teeth. ## How is a toothache treated? Treatment depends on the cause. Cleveland Clinic describes these paths: Cause Typical treatment Small cavity or small break A filling Larger cavity or crack A crown, or an inlay or onlay Infection reaching the pulp A [root canal](https://towncenterdental.multisites.ai/services/root-canal) Badly damaged tooth Removing the tooth, then talking about replacement Grinding A night guard, and care for worn teeth Cleveland Clinic says a root canal is needed when bacteria from a cavity or crack invade the tooth pulp. Our [root canal page](https://towncenterdental.multisites.ai/services/root-canal) explains the steps. The dentist will talk with you about what fits your tooth and what to expect. NIDCR notes that early tooth decay usually has no symptoms. By the time a tooth aches, decay may be deeper. This is why regular exams matter even when nothing hurts. ## When is a toothache an emergency? Some toothaches need care today. Cleveland Clinic says to call a dentist or go to the nearest emergency room if you have unbearable tooth pain along with fever and chills. It says infection in the mouth can, though it is rare, spread to other parts of the body. Go to an emergency room for any of these signs, per Cleveland Clinic and Mayo Clinic: - Swelling below your eye or a knot on your jaw - Unbearable tooth pain that does not get better with medication - Bleeding that will not stop with pressure - A fever over 101 degrees Fahrenheit - Trouble breathing or swallowing Our [dental emergency guide](https://towncenterdental.multisites.ai/guides/dental-emergency-guide) covers first aid and where to go. ## What if the pain starts when the office is closed? Town Center Dental is open Monday to Wednesday from 8am to 5pm and Thursday from 8am to 4pm. The office is closed Friday to Sunday. This website lists no after-hours number. If a severe toothache starts when the office is closed, go to an emergency room. Cleveland Clinic says an ER can give medicine for pain and swelling but does not do fillings or crowns. Call the office when it opens so you can plan the dental care. For mild pain on a closed day, use the home steps above. Then call as soon as the office opens. Cleveland Clinic says a toothache that lingers longer than a day or two needs a dentist. ## How can you lower the chance of a toothache? Daily care and regular visits help. Cleveland Clinic suggests brushing two to three times a day with a fluoride toothpaste and a soft toothbrush, visiting your dentist for exams and cleanings, and asking about sealants and fluoride treatments. Cavities cause many toothaches. Limit sugary drinks and snacks between meals, and clean between your teeth once a day. If you grind your teeth, ask your dentist whether a night guard makes sense. Our [night guard page](https://towncenterdental.multisites.ai/services/night-guards) explains the practice’s description of this care. ## Next step If a tooth hurts, do not wait for it to stop. Read about the practice’s [emergency dentistry](https://towncenterdental.multisites.ai/services/emergency-dentistry), then call (636) 273-5866 during office hours or [request an appointment](https://towncenterdental.multisites.ai/request-appointment). Tell the team where it hurts, how long, and whether you have swelling or fever. ## Frequently asked questions ### What is the best toothache relief at home? Cleveland Clinic lists a warm saltwater rinse, a cold pack on the outside of the jaw, and over-the-counter pain relievers such as acetaminophen or ibuprofen. These may ease mild pain for a short time. They do not treat the cause, so book a dental visit. Follow the label and ask your pharmacist if unsure. ### Can a toothache go away on its own? Sometimes. Cleveland Clinic says pain from irritated gums, such as after biting something hard, will likely pass in a day or two. But a true toothache, pain that comes from the tooth itself, usually means a problem that needs treatment. If pain lingers more than a day or two, call a dentist. ### How is a dental abscess treated? A dentist finds the source of the infection and treats it, often with a root canal or by removing the tooth. Cleveland Clinic says antibiotics and pain relievers ease symptoms for a time, but the infection returns unless the cause is treated. Swelling, fever, or trouble breathing needs an emergency room. ### Why does my tooth hurt when I bite down? Cleveland Clinic says a sharp, stabbing pain might mean a cavity or a crack, and sometimes a problem with a filling or crown. Only an exam and X-ray can tell which one. Avoid chewing on that side and call the dentist. Pain that gets worse should be seen soon. ### When is a toothache an emergency? Cleveland Clinic says go to the emergency room for swelling below the eye or a knot on the jaw, pain that medicine does not ease, bleeding that will not stop, or a fever over 101 degrees Fahrenheit. Mayo Clinic adds trouble breathing or swallowing. Otherwise call your dentist as soon as the office opens. ## Terms on this page - [Gum disease (periodontal disease)](https://towncenterdental.multisites.ai/glossary/gum-disease-periodontal-disease) - [Bruxism (teeth grinding)](https://towncenterdental.multisites.ai/glossary/bruxism-teeth-grinding) - [Cavity (dental caries)](https://towncenterdental.multisites.ai/glossary/cavity-dental-caries) - [Fluoride toothpaste](https://towncenterdental.multisites.ai/glossary/fluoride-toothpaste) - [Tooth sensitivity](https://towncenterdental.multisites.ai/glossary/tooth-sensitivity) - [Dental emergency](https://towncenterdental.multisites.ai/glossary/dental-emergency) - [Gums (gingiva)](https://towncenterdental.multisites.ai/glossary/gums-gingiva) - [Night guard](https://towncenterdental.multisites.ai/glossary/night-guard) - [Tooth decay](https://towncenterdental.multisites.ai/glossary/tooth-decay) - [Tooth pulp](https://towncenterdental.multisites.ai/glossary/tooth-pulp) ## Sources 1.
