A throbbing pain in your back tooth that intensifies with pressure is a common dental problem, often signaling an underlying issue requiring professional attention. Ignoring the pain could lead to more serious complications, so understanding the potential causes and seeking timely treatment is crucial. This comprehensive guide explores the various reasons why your back tooth might hurt under pressure, offering insights into diagnosis, treatment, and preventative measures.
What Causes a Back Tooth to Hurt with Pressure?
Several factors can cause pressure sensitivity in your back molars. The pain often indicates inflammation or damage to the tooth's structure or surrounding tissues. Here are some of the most common culprits:
-
Cavities (Dental Caries): Bacteria produce acids that erode tooth enamel, creating cavities. As the decay progresses, it reaches the dentin, a more sensitive layer beneath the enamel, leading to pain when pressure is applied, such as during chewing.
-
Gum Disease (Gingivitis/Periodontitis): Inflammation and infection of the gums can lead to sensitivity and pain. As the gums recede, the tooth roots become exposed, making them vulnerable to pressure. Advanced gum disease can even damage the supporting bone structure, further exacerbating the pain.
-
Cracked or Fractured Tooth: A crack or fracture, sometimes invisible to the naked eye, can expose the dentin or pulp (the inner soft tissue of the tooth), causing significant pain, particularly with pressure. This can result from trauma, clenching, or grinding your teeth.
-
Abscess: An abscess is a pocket of pus caused by a bacterial infection at the root of the tooth. The pressure from the infection leads to intense throbbing pain that worsens when pressure is applied.
-
Bruxism (Teeth Grinding): Chronic teeth grinding or clenching, often done unconsciously, can wear down tooth enamel, leading to sensitivity and pain. This can manifest as pain specifically when biting down.
-
Dental Procedures: Recently completed dental work, such as fillings or crowns, may initially cause some temporary sensitivity. However, persistent pain indicates a potential problem.
-
Sinus Infection: While less common, a sinus infection can sometimes refer pain to the upper back teeth, particularly the upper molars. This is because the roots of the upper molars are close to the maxillary sinuses.
How is a Pressure-Sensitive Back Tooth Diagnosed?
Your dentist will conduct a thorough examination to pinpoint the cause of your pain. This might include:
- Visual Examination: A close inspection of your teeth and gums to detect visible signs of decay, cracks, or gum disease.
- X-rays: To identify cavities, abscesses, fractures, or bone loss.
- Percussion Test: Gently tapping on the affected tooth to assess its sensitivity.
- Palpation: Feeling around the affected area to check for swelling or tenderness.
What Treatment Options Are Available?
Treatment will depend on the underlying cause:
- Cavities: Fillings are usually sufficient to restore the tooth's structure and eliminate the pain.
- Gum Disease: Treatment may involve scaling and root planing (cleaning beneath the gum line) and potentially antibiotics to combat infection.
- Cracked or Fractured Tooth: Treatment options range from dental bonding to crowns, depending on the severity of the fracture. In severe cases, extraction might be necessary.
- Abscess: Root canal treatment or extraction may be required to eliminate the infection.
- Bruxism: Your dentist might recommend a mouthguard to prevent further damage from teeth grinding.
Can I Prevent a Back Tooth from Hurting with Pressure?
Preventive measures play a crucial role in maintaining oral health and avoiding pressure-sensitive teeth:
- Maintain Excellent Oral Hygiene: Brush twice daily with fluoride toothpaste and floss regularly to remove plaque and food particles.
- Regular Dental Checkups: Visit your dentist for professional cleanings and examinations at least twice a year. Early detection of problems can prevent more extensive and painful treatments.
- Healthy Diet: Limit sugary and acidic foods and drinks, which contribute to tooth decay.
- Manage Stress: Stress can exacerbate bruxism, so exploring stress-reduction techniques might be beneficial.
Is a Pressure-Sensitive Back Tooth Always an Emergency?
While not always an immediate emergency, persistent pain or severe symptoms warrant prompt professional attention. If you experience intense pain, swelling, fever, or difficulty opening your mouth, seek emergency dental care immediately.
How Long Does it Take for a Pressure-Sensitive Back Tooth to Heal?
The healing time depends on the underlying cause and the type of treatment received. Simple treatments like fillings might take only a few days for the discomfort to subside. More complex procedures like root canals may require several weeks for complete healing.
