Tooth Sensitivity? It Might Be Time for a Root Canal

When is tooth sensitivity more than just a minor issue?

Tooth sensitivity can stem from several causes, such as brushing too hard, consuming acidic foods, or using whitening products. However, sensitivity that persists for days, worsens over time, or is triggered by hot, cold, or sweet foods may indicate deeper damage inside the tooth.

When the inner pulp becomes infected due to deep decay, trauma, or repeated dental work, it can’t heal on its own. This condition not only causes ongoing pain but can also spread to nearby tissues if left untreated. Root canal therapy is the only effective way to remove the infected tissue and preserve the tooth.

How does a root canal relieve sensitivity?

Root canal treatment involves removing the inflamed or infected pulp, thoroughly cleaning the inner tooth, and sealing it to prevent future infections. Once the source of irritation is gone, sensitivity disappears because the nerve endings responsible for the pain have been removed.

Despite its reputation, a root canal is no more painful than a regular filling thanks to modern anaesthesia and technology. At White Perfect Dental, we ensure our patients are comfortable and informed throughout the procedure.

By acting quickly, we can prevent the need for more complex and costly procedures like tooth extractions and implants.

What symptoms suggest you may need a root canal?

If you’re experiencing any of the following warning signs, it could be an indication that the pulp inside your tooth is inflamed or infected, and professional evaluation is necessary:

• Sharp or throbbing tooth pain: Pain that intensifies when biting or applying pressure often suggests damage or infection deep inside the tooth. This discomfort may come and go or be constant, and it typically worsens without treatment.
  
  
• Lingering sensitivity to temperature or sweetness: While brief sensitivity is common, discomfort that lingers after eating or drinking something hot, cold, or sweet could point to nerve damage within the tooth.
  
  
• Tooth discolouration: A tooth that appears grey, brown, or significantly darker than its neighbours may have compromised blood flow due to infection or trauma affecting the pulp.
  
  
• Swelling or tenderness in the gums: Inflamed gums around a single tooth, especially if accompanied by a painful bump or abscess (which may drain pus), strongly suggest an underlying infection that may require root canal therapy.
  
  
• Cracked or broken tooth: A fracture that extends deep into the tooth can expose the pulp to bacteria, significantly increasing the risk of infection. Even if the crack isn’t visible, any trauma should be examined promptly.
  
  

These symptoms are not only uncomfortable but also signal that the internal structure of your tooth may be compromised. Ignoring them could allow the infection to spread, potentially leading to an abscess, jawbone deterioration, or even systemic issues. Prompt diagnosis and treatment with a root canal can save the tooth and restore your oral health.

How long does root canal relief last?

A successful root canal can provide long-lasting relief and functionality, often preserving the treated tooth for decades or even a lifetime. The durability of a root canal largely depends on factors such as the complexity of the case, the skill of the dentist, and, most importantly, how well the patient maintains their oral health afterward.

After the procedure, a dental crown is typically placed over the treated tooth. This crown plays a crucial role in protecting the weakened tooth structure from future fractures, wear, or reinfection, particularly in molars and premolars that endure high chewing forces.

While some patients may experience mild sensitivity for a few days post-treatment, this typically resolves as inflammation subsides and healing progresses. Persistent discomfort is rare and should be evaluated to rule out complications.

To ensure long-term success, patients should:

• Maintain excellent oral hygiene, including daily brushing and flossing
  
  
• Avoid chewing on hard objects like ice or pens
  
  
• Schedule routine dental check-ups for monitoring
  
  
• Seek prompt care for any signs of dental trauma or decay
  
  

At White Perfect Dental, we focus on preventive care and post-treatment monitoring to help ensure that your root canal treatment remains successful and your tooth stays healthy and pain-free for years to come.
