Back tooth pain is a common issue that many people experience, but it can be difficult to identify the exact cause. Pain in the molars or wisdom teeth may come from cavities, infection, gum disease, or even issues with the jaw joint. Because the back teeth are harder to reach, problems can progress further before symptoms become noticeable. Understanding the common causes of back toothache and the treatment options available can help you find relief sooner and prevent more serious complications.

1. What Is Back Tooth Pain?
Back toothache refers to discomfort or pain in the molars or wisdom teeth, which are located at the rear of the mouth. This type of pain can range from mild sensitivity to severe, throbbing discomfort. Back tooth pain may be caused by dental problems such as cavities, infection, or gum disease, but it can also be related to jaw issues or even sinus pressure. Because the back teeth play a major role in chewing and biting, pain in this area can significantly affect daily activities.
2. Common Causes of Back Tooth Pain
Back toothache can develop for many reasons. One of the most common causes is tooth decay, which often starts in the molars due to food getting trapped in grooves and between teeth. Gum disease can also lead to pain in the back teeth, especially if the infection reaches the tooth roots or causes gum recession. Another common cause is grinding or clenching teeth, which can strain the back teeth and jaw muscles. In some cases, pain may be caused by a cracked tooth or damaged filling, allowing bacteria to reach the tooth nerve.
3. Molar Tooth Pain: Why It Happens
Molar toothache is often caused by cavities or decay because molars have deep grooves that are harder to clean. When decay reaches the dentin or pulp, it can cause sensitivity and pain. Molars also experience high pressure during chewing, so even a small cavity or crack can cause significant discomfort. In some cases, molar pain can be caused by a failing filling or a cracked tooth that exposes the nerve. If left untreated, molar pain can progress to infection and abscess.
4. Wisdom Tooth Pain and Impacted Teeth
Wisdom toothache is common because these teeth often do not have enough space to grow properly. Impacted wisdom teeth can push against neighboring teeth, causing pressure, swelling, and pain. In some cases, wisdom teeth may partially erupt, creating a flap of gum tissue that traps food and bacteria, leading to infection and pain. If a wisdom tooth is severely impacted or infected, a dentist may recommend extraction to prevent ongoing pain and complications.
5. Back Tooth Pain While Chewing
Back tooth pain while chewing often indicates a problem with the tooth structure or nerve. Pain that worsens with biting or chewing may be caused by a cracked tooth, cavity, or a damaged filling. It can also signal inflammation or infection in the tooth pulp. If the pain is sharp or sudden when biting, it may mean the tooth is cracked and needs immediate attention. Chewing on the affected side may temporarily reduce pain, but it does not treat the underlying cause.
6. Back Tooth Infection and Abscess
A back tooth infection occurs when bacteria reach the tooth pulp through decay, cracks, or injury. The infection can spread to the root tip and surrounding bone, leading to an abscess. Symptoms of a back tooth infection may include severe pain, swelling, sensitivity to hot or cold foods, bad taste, and fever in severe cases. An abscess can cause swelling in the face or jaw and may require urgent dental treatment to prevent the infection from spreading further.
7. Treatment Options for Back Tooth Pain
Treatment for back toothache depends on the cause. If the pain is due to a cavity, the dentist may remove the decay and place a filling. For more severe decay or infection, a root canal may be needed to remove the infected pulp and save the tooth. In cases of severe damage or impacted wisdom teeth, extraction may be recommended. If gum disease is the cause, deep cleaning or periodontal treatment may be necessary. For those who grind their teeth, a night guard can reduce pressure and protect the back teeth.
8. When to Seek Urgent Dental Care
You should seek urgent dental care if back toothache is severe, worsening, or accompanied by swelling. Seek emergency treatment if swelling spreads to the face or neck, if you have fever, or if you experience difficulty swallowing or breathing. If you notice pus or a bad taste in your mouth, or if the pain lasts more than a few days, it is important to get dental care promptly. These signs may indicate a serious infection or abscess that needs immediate treatment.
9. Preventing Back Tooth Pain
Preventing back tooth pain starts with consistent oral hygiene and regular dental checkups. Brushing twice daily with fluoride toothpaste and flossing daily removes plaque and food particles that can lead to cavities and gum disease. Avoid chewing on hard foods or ice, and limit sugary snacks and drinks that can increase decay. Using a mouthguard can protect your back teeth if you grind or clench your teeth at night. Regular dental cleanings help detect issues early before they become painful or require more complex treatment.
