Toothaches are most often caused by tooth decay, gum disease, cracked teeth, dental infections, and teeth grinding. Some toothaches are mild and go away on their own within a day or two. Others signal a deeper problem that will get worse without treatment. Knowing the difference between a minor ache and a sign of something serious can help you protect your teeth and avoid a painful emergency. This article breaks down the most common causes of tooth pain and explains exactly when you should see a dentist.
Common Causes of Toothache Pain
Tooth pain can come from many sources. Some are easy to fix with a quick office visit. Others require more involved treatment. Understanding what is behind the pain helps you take the right next step.
Tooth Decay (Cavities)
Tooth decay is the single most common cause of toothaches. According to the NIDCR, nearly 90% of adults aged 20 to 64 have experienced tooth decay at some point. The CDC reports that about 26% of adults aged 20 to 44 currently have at least one untreated cavity. When decay eats through the outer enamel and reaches the softer dentin layer underneath, the tooth becomes sensitive to temperature, sweets, and pressure. If the decay reaches the pulp, the pain becomes constant and severe.
Gum Disease
Gum disease is another leading cause of tooth pain and tooth loss. The CDC estimates that 47.2% of adults aged 30 and older have some form of periodontal disease, and that number jumps to 70.1% in adults over 65. In its early stage, called gingivitis, the gums become red, swollen, and bleed easily. If left untreated, it progresses to periodontitis, where the gums pull away from the teeth and the supporting bone breaks down. This can cause aching, loose teeth, and sharp pain when chewing.
Cracked or Fractured Teeth
A cracked tooth can cause pain that comes and goes, especially when biting down or releasing a bite. Cracks can result from trauma, biting on hard objects, or years of grinding. An ADA Health Policy Institute poll found that 63% of dentists reported an increase in cracked teeth in recent years, with stress-related clenching being a major factor. Even a small crack can allow bacteria to enter the inner layers of the tooth and cause infection.
Teeth Grinding (Bruxism)
Grinding and clenching put heavy pressure on the teeth, jaw muscles, and joints. The International Classification of Sleep Disorders notes that 85% to 90% of people grind their teeth to some degree during their lifetime. Chronic grinding wears down enamel, increases sensitivity, and can lead to cracked teeth, headaches, and jaw soreness. Many people grind at night without realizing it.
Dental Abscess
A dental abscess is a pocket of pus caused by a bacterial infection at the root of a tooth or in the surrounding gum tissue. Abscesses cause intense, throbbing pain that often radiates to the jaw, ear, or neck. The Mayo Clinic states that a tooth abscess will not resolve on its own and can spread to the jaw, head, and neck if left untreated. According to the Healthcare Cost and Utilization Project, abscesses and dental caries accounted for nearly 80% of all dental-related ER visits.
Other causes of toothaches include impacted wisdom teeth, a damaged filling or crown, sinus pressure that refers pain to the upper teeth, and food trapped between teeth that irritates the gums.
Patients in Cinnaminson, NJ who are experiencing any form of persistent tooth pain should schedule a visit rather than waiting for the pain to resolve. Many of the conditions listed above get worse over time.
We provide a full range of general dentistry services to diagnose and treat the source of tooth pain, from fillings and crowns to root canals and extractions.
How Do I Tell if My Toothache Is Serious?
You can tell if your toothache is serious by looking at the type of pain, how long it lasts, and whether other symptoms are present. A mild, brief sensitivity to cold or sweets that fades quickly is usually not an emergency. A toothache that lasts more than one to two days, keeps you awake at night, or gets progressively worse likely points to a deeper problem.
Signs that a toothache is serious include pain that does not respond to over-the-counter medicine, swelling in the face or jaw, a fever, a bad taste in the mouth, pain that spreads to the ear or neck, and difficulty opening the mouth.
The NIDCR reports that nearly 1 in 5 adults in the United States experience moderate to high dental fear and anxiety, which often leads to delayed treatment. According to the ADA, 22% of adults have reported putting off dental care because of anxiety. Waiting too long often turns a treatable cavity or minor infection into a much larger problem.
South Jersey residents dealing with tooth pain that matches any of the warning signs above should call a dentist the same day. Early treatment almost always means less pain, less time in the chair, and a better outcome.
Knowing when a toothache crosses into emergency territory can help you make the right decision quickly.
When You Should See a Dentist for Tooth Pain
Not every toothache requires an urgent visit, but certain situations call for prompt care. As a general rule, you should see a dentist if tooth pain lasts more than one to two days, if it is getting worse instead of better, or if it is accompanied by other symptoms like swelling, fever, or bleeding.
Specific situations that call for a dental visit include a cavity that has become painful, a cracked or broken tooth, a loose or lost filling or crown, gum pain or bleeding that will not stop, pain after a recent dental procedure that is getting worse instead of improving, and any sign of infection such as swelling, pus, or a foul taste.
Some situations require same-day care. A knocked-out tooth, severe facial swelling, uncontrolled bleeding, or a tooth infection paired with fever should all be treated as emergencies.
We offer emergency dental appointments for patients in Cinnaminson and the surrounding Burlington County communities, including Moorestown, Delran, Maple Shade, and Mount Laurel.
For patients unsure whether to see a dentist or head to an emergency room, comparing an emergency dentist visit to an ER visit can help clarify the best option.
What Happens if a Toothache Goes Untreated
A toothache that goes untreated almost always gets worse. What starts as a small cavity can progress to deep decay, pulp infection, and eventually an abscess. At that point, the only options may be a root canal or extraction.
The NIDCR notes that untreated tooth decay cost the United States approximately $45.9 billion in lost productivity in 2015. The ADA adds that dental problems lead to roughly 34 million lost school hours and 92 million lost work hours each year. These numbers show just how much impact delayed dental care has on everyday life.
An untreated infection can spread beyond the tooth into the jaw, the floor of the mouth, or deeper spaces in the neck. The Sepsis Alliance warns that dental infections can lead to sepsis if bacteria enter the bloodstream. While rare, this is a life-threatening complication that requires emergency medical treatment.
The CDC identifies cavities and periodontal disease as the two leading causes of tooth loss in adults. Both are highly preventable with regular dental care. Patients who address tooth pain early are far more likely to keep their natural teeth.
When the damage reaches the pulp of the tooth, treatment typically involves deciding between a root canal and extraction based on how much healthy tooth structure remains.
How Your Dentist Finds the Source of Tooth Pain
Finding the exact cause of a toothache requires a thorough exam. A dentist will review your symptoms, take X-rays, and test the tooth in several ways to narrow down the problem. Common diagnostic steps include checking for visible decay or damage, testing sensitivity to hot and cold, tapping on individual teeth to locate the source of pain, and examining the gums for signs of infection or recession.
In some cases, the pain is not coming from the tooth at all. Sinus infections, TMJ disorders, and referred pain from other areas can all mimic a toothache. A proper diagnosis prevents unnecessary treatment and gets you relief faster.
The table below compares common toothache causes, their typical symptoms, and the treatments a dentist may recommend.
| Cause | Common Symptoms | Typical Treatment |
|---|---|---|
| Tooth Decay (Cavity) | Sensitivity to sweets, hot, cold; visible hole or dark spot | Filling or crown |
| Gum Disease | Red, swollen, or bleeding gums; receding gumline; loose teeth | Deep cleaning (scaling and root planing) |
| Cracked Tooth | Sharp pain when biting; pain that comes and goes | Crown, root canal, or extraction |
| Dental Abscess | Throbbing pain, swelling, fever, bad taste | Drainage, antibiotics, root canal, or extraction |
| Bruxism (Grinding) | Jaw soreness, headaches, worn-down teeth | Night guard, stress management |
| Lost Filling or Crown | Sharp pain, sensitivity, rough edge on tooth | New filling or crown |

Frequently Asked Questions
How Long Should You Have Tooth Pain Before Seeing a Dentist?
You should see a dentist if tooth pain lasts more than one to two days or is getting worse. Mild, brief sensitivity after eating something cold or sweet may not need immediate attention. But persistent pain, especially when combined with swelling or fever, means something is wrong and needs professional evaluation. The longer you wait, the more likely a small problem becomes a bigger one.
What Can I Do for Tooth Pain Until I Can See a Dentist?
For tooth pain until you can see a dentist, rinse your mouth gently with warm salt water to reduce bacteria and soothe the area. A cold compress applied to the outside of your cheek for 10 to 15 minutes can reduce swelling. Over-the-counter pain medicine like ibuprofen or acetaminophen can help manage discomfort. Avoid very hot, cold, or sugary foods, and do not chew on the painful side. These steps provide temporary relief but are not a substitute for professional treatment.

How Long Do Toothaches Usually Last?
Toothaches usually last anywhere from a few hours to several days, depending on the cause. A toothache caused by minor gum irritation or temporary sensitivity may go away within 24 to 48 hours. A toothache caused by a cavity, crack, or infection will not go away on its own and will likely get worse over time. If pain persists beyond two days, it is time to see a dentist.
How Do I Sleep with a Toothache?
To sleep with a toothache, keep your head elevated with an extra pillow to reduce blood flow to the area and minimize throbbing. Take an over-the-counter pain reliever about 30 minutes before bed. A cold compress on your cheek before lying down can also help numb the pain. Avoid eating anything hot, cold, or acidic close to bedtime. These steps can provide enough relief to get some rest, but make sure to see a dentist the next day.
What Are the Signs of a Tooth Infection Spreading?
The signs of a tooth infection spreading include swelling that moves from the tooth area into the cheek, jaw, or neck; a fever; a rapid heartbeat; difficulty swallowing or breathing; and a general feeling of being unwell. The Sepsis Alliance notes that dental infections can enter the bloodstream and lead to sepsis if left untreated. If you notice any of these symptoms alongside tooth pain, seek emergency care right away.
Knowing the right place to go in an emergency matters. Patients in the Burlington County area can learn more about choosing between an emergency dentist and a walk-in clinic for dental concerns.
What Worsens a Tooth Infection?
A tooth infection worsens when it does not receive professional treatment. Delaying care gives bacteria more time to multiply, destroy tooth structure, and spread into surrounding tissues and bone. Smoking, a high-sugar diet, poor oral hygiene, and a weakened immune system can all accelerate the progression of a dental infection. Over-the-counter pain medicine may mask the symptoms, but it does not stop the infection from advancing.
The Bottom Line
Tooth pain is your body's way of telling you something needs attention. The cause might be a cavity, gum disease, a crack, grinding, or an infection. Some of these problems start small but grow quickly without treatment. The sooner you see a dentist, the simpler and less painful the fix tends to be.
Paying attention to your symptoms and acting early is the best way to protect your teeth and avoid a costly emergency. Regular checkups, good daily brushing and flossing habits, and not ignoring pain are the foundation of a healthy smile.
