Experiencing pain in your back teeth when biting down can be incredibly frustrating and disruptive. This symptom can stem from various dental issues, ranging from relatively minor to more serious problems. Understanding the potential causes is crucial for seeking the right treatment and alleviating your discomfort. This article will explore the common reasons behind this type of toothache, offering insights into potential diagnoses and the importance of consulting a dentist.
What Causes Back Tooth Pain When Biting Down?
Several factors can contribute to pain in your back teeth when you bite down. Let's delve into some of the most frequent culprits:
Cavities (Dental Caries):
One of the most common causes of tooth pain is a cavity. Bacteria in your mouth produce acids that erode tooth enamel, creating holes (cavities) that can reach the sensitive dentin and pulp. When you bite down, pressure on the affected tooth can exacerbate the pain. The pain might be sharp, throbbing, or a dull ache, depending on the cavity's severity and location.
Cracked or Broken Tooth:
A crack or fracture in a back tooth, often invisible to the naked eye, can cause significant pain when biting down. The crack might extend into the dentin or pulp, causing sensitivity to pressure and temperature changes. Trauma, such as biting down on a hard object, is a common cause of cracked teeth.
Abscessed Tooth:
An abscessed tooth is a serious infection at the root of a tooth. The infection can cause intense pain, swelling, and sensitivity to pressure. When you bite down, the pressure on the infected area intensifies the pain, often making it unbearable. Abscesses require immediate professional attention to prevent the spread of infection.
Gum Disease (Periodontal Disease):
Gum disease, characterized by inflammation and infection of the gums, can affect the supporting structures of your teeth. As the gums recede, the roots of your teeth become exposed, making them sensitive to pressure and temperature. Biting down can then trigger pain in the affected teeth.
Temporomandibular Joint (TMJ) Disorder:
TMJ disorders affect the jaw joint and surrounding muscles, causing pain in the jaw, face, and ears. While not directly related to the teeth themselves, TMJ problems can lead to pain when biting down, particularly affecting the back teeth. This pain is often accompanied by clicking or popping sounds in the jaw.
Bruxism (Teeth Grinding):
Bruxism, the unconscious grinding or clenching of teeth, particularly at night, can wear down tooth enamel and cause pain in the back teeth when biting down. The constant pressure from grinding puts stress on the teeth, leading to sensitivity and pain.
Dental Filling Problems:
Old or damaged dental fillings can cause pain when biting down. The filling might have cracked, loosened, or fallen out, leaving the underlying tooth exposed and vulnerable.
Sinus Infection:
Although less common, a sinus infection can sometimes cause referred pain in the upper back teeth. The pressure from the infection in the sinuses can radiate to the teeth, leading to pain when biting down.
How Can I Tell What's Wrong?
Self-diagnosing is difficult and unreliable. The best way to determine the cause of your back tooth pain when biting down is to schedule an appointment with your dentist. They can perform a thorough examination, take X-rays if necessary, and accurately diagnose the problem. Early diagnosis and treatment are crucial to prevent more severe complications.
What Should I Do Until I See a Dentist?
While waiting for your dental appointment, you can try these measures to alleviate some discomfort:
- Over-the-counter pain relievers: Ibuprofen or acetaminophen can help reduce pain and inflammation.
- Avoid chewing on the affected side: This will minimize pressure on the painful tooth.
- Use a cold compress: Apply a cold compress to the affected area to reduce swelling.
