A throbbing ache in your back tooth that intensifies with pressure is never fun. This discomfort can significantly impact your daily life, making eating and even talking difficult. Understanding the potential causes behind this pain is the first step towards finding relief. This comprehensive guide explores various reasons why your back tooth might hurt under pressure, outlining potential treatments and when professional dental care becomes necessary.
What Causes a Back Tooth to Hurt with Pressure?
Several factors can contribute to pressure sensitivity in a back molar. Let's explore some of the most common:
1. Cavities (Dental Caries):
This is often the primary culprit. A cavity develops when bacteria in plaque erode the enamel, creating a hole in your tooth. As the decay progresses, it reaches the dentin, a more sensitive layer beneath the enamel. Pressure on the tooth exposes the sensitive dentin, leading to sharp pain.
2. Cracked Tooth:
A crack in your tooth, even a microscopic one, can cause significant pain when pressure is applied. This pain is often localized and worsens with chewing or biting. Cracked teeth require prompt dental intervention to prevent further damage.
3. Abscess:
An abscess is a pocket of pus that forms at the root of a tooth due to a severe infection. The pressure from the pus can cause intense throbbing pain, particularly when pressure is applied to the affected tooth. Abscesses require immediate dental treatment to prevent serious complications.
4. Gum Disease (Periodontal Disease):
Gum disease, if left untreated, can lead to inflammation and infection around the tooth root. This can cause sensitivity and pain, especially when pressure is applied. Good oral hygiene practices are crucial in preventing gum disease.
5. Tooth Grinding (Bruxism):
Grinding your teeth, often unconsciously, can weaken the enamel and cause micro-fractures, leading to sensitivity and pain, particularly under pressure. A dentist can provide custom mouthguards to protect your teeth from the effects of bruxism.
6. Tooth Sensitivity:
Sometimes, general tooth sensitivity can be exacerbated, causing pain with pressure. This may be due to exposed dentin, enamel erosion, or receding gums.
7. Sinusitis:
While less common, sinus infections can sometimes cause referred pain in the upper back teeth. The pressure from the sinus infection might be felt as pain in the tooth.
What Can I Do for a Pressure-Sensitive Back Tooth at Home?
While home remedies can provide temporary relief, they should not replace professional dental care. Here are a few things you can try:
- Over-the-counter pain relievers: Ibuprofen or acetaminophen can help manage pain.
- Saltwater rinse: Gently rinsing your mouth with warm salt water can help soothe inflamed gums.
- Avoid chewing on the affected side: This will minimize pressure on the sensitive tooth.
- Use a soft toothbrush: Brushing too hard can worsen sensitivity.
When Should I See a Dentist?
If your back tooth pain persists despite home remedies, or if it's accompanied by swelling, fever, or severe throbbing, it's crucial to see a dentist immediately. Delaying treatment can lead to more serious complications, such as an abscess or the loss of the tooth. A dentist can accurately diagnose the problem and recommend the appropriate treatment.
How Does a Dentist Treat Pressure Sensitivity in a Back Tooth?
Treatment options depend on the underlying cause:
- Fillings: For cavities, a dentist will clean the affected area and fill the cavity to restore the tooth's structure.
- Root canal: If the infection reaches the pulp (the soft tissue inside the tooth), a root canal may be necessary to remove the infected pulp and save the tooth.
- Crown: A crown is a cap that fits over the tooth, protecting it from further damage and restoring its function.
- Extraction: In severe cases, the tooth may need to be extracted.
- Mouthguard: If bruxism is the cause, a custom-fitted mouthguard can protect your teeth.
Remember, prompt dental care is essential for preserving your oral health. Don't hesitate to schedule an appointment if you experience persistent pain or discomfort in your back tooth.
