A throbbing pain in your back tooth that intensifies with pressure is a common dental problem, but pinpointing the exact cause requires professional assessment. This discomfort can range from a minor annoyance to a debilitating ache, significantly impacting your daily life. Understanding the potential reasons behind this pain is crucial for effective treatment and preventing future complications. This comprehensive guide explores the common causes, treatment options, and when it's essential to seek immediate dental care.
What Causes a Back Tooth to Hurt with Pressure?
Several factors can cause pressure sensitivity in your back molars. These include:
-
Cavities (Dental Caries): This is a prevalent cause. Bacteria produce acids that erode tooth enamel, creating cavities. As the cavity deepens, it reaches the dentin, a layer sensitive to temperature and pressure changes, resulting in pain.
-
Cracked Tooth: A crack, even a microscopic one, can expose the inner layers of your tooth, leading to sensitivity and pain when pressure is applied, such as during chewing. Cracks can be caused by trauma, grinding teeth (bruxism), or decay.
-
Gum Disease (Periodontal Disease): Inflammation and infection of the gums can lead to gum recession, exposing the tooth roots and making them vulnerable to pressure sensitivity.
-
Abscess: A painful pus-filled pocket (abscess) can form at the root of the tooth due to infection. The pressure from the abscess can cause intense pain, especially when biting or chewing.
-
Sinus Infection: Sinus infections can sometimes refer pain to the upper back teeth. The proximity of the sinuses to the upper molars means that pressure or inflammation in the sinuses can cause discomfort that feels like toothache.
-
Impacted Wisdom Tooth: A wisdom tooth that's partially or fully impacted (unable to erupt fully) can cause pain, swelling, and pressure sensitivity in neighboring teeth.
-
Bruxism (Teeth Grinding): Chronic grinding or clenching of teeth, often unconscious, can wear down tooth enamel and cause sensitivity and pain, particularly in the back teeth which bear the brunt of the chewing force.
-
Dental Work Complications: Sometimes, pain can arise from complications related to previous dental procedures, such as a poorly fitted crown, filling, or root canal treatment.
How is Pressure Sensitivity in a Back Tooth Treated?
Treatment depends entirely on the underlying cause. Your dentist will conduct a thorough examination, possibly including X-rays, to diagnose the problem accurately. Potential treatments include:
-
Fillings: For cavities, fillings are used to restore the damaged tooth structure and alleviate pain.
-
Crowns: If a tooth is significantly damaged or cracked, a crown (cap) may be necessary to protect and restore it.
-
Root Canal: If the infection has reached the pulp (inner part of the tooth), a root canal might be needed to remove the infected tissue, clean the canals, and seal them to prevent further infection.
-
Extraction: In severe cases of infection or irreparable damage, extraction (tooth removal) may be the only option.
-
Scaling and Root Planing: For gum disease, scaling and root planing (deep cleaning) can remove plaque and tartar buildup, improving gum health and reducing sensitivity.
-
Mouthguard: For bruxism, a custom-fitted mouthguard can protect teeth from further damage and reduce pain.
When Should I See a Dentist for a Back Tooth That Hurts with Pressure?
You should schedule an appointment with your dentist as soon as possible if:
- The pain is severe or persistent: Don't wait for the pain to subside on its own.
- The pain is accompanied by swelling or fever: This could indicate a serious infection.
- You notice pus or drainage from the gum: This is a sign of an abscess.
- The pain interferes with your ability to eat or sleep: This significantly impacts your quality of life.
Can I Treat a Pressure-Sensitive Back Tooth at Home?
While home remedies can provide temporary relief, they are not a substitute for professional dental care. Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage pain. Rinsing your mouth with warm salt water may temporarily soothe irritated gums. However, these measures only address the symptoms, not the underlying cause. A dental examination is crucial for accurate diagnosis and appropriate treatment.
What are the Long-Term Effects of Ignoring a Pressure-Sensitive Back Tooth?
Neglecting a pressure-sensitive back tooth can lead to serious complications, including:
- Spread of infection: An untreated infection can spread to other teeth, the jawbone, or even the bloodstream.
- Tooth loss: Severe decay or infection can result in tooth loss.
- Abscess formation: An untreated infection can lead to the formation of a painful abscess.
- Jawbone damage: Severe infection can damage the supporting bone structure of the tooth.
Ignoring dental pain can have far-reaching consequences. Early intervention is key to preserving your oral health and preventing more extensive, costly treatments down the line. Schedule an appointment with your dentist to address your concerns promptly.
