Exposed Tooth Roots: Causes, Symptoms, and Effective Treatments


Many people are concerned about exposed tooth roots. It's not just about aesthetics; if left untreated, exposed tooth roots can lead to sensitivity and other complications.

This article from Serene Dental Center will explain what tooth roots are and why they're important, the signs and symptoms of exposed tooth roots, the common causes, potential complications, and treatment options.

We'll also discuss how to prevent exposed tooth roots and when to see a dentist.

Understanding Tooth Roots

The Hidden Foundation

Your teeth might seem like solid units, but they actually have two distinct parts. The visible portion above the gum line is the crown, responsible for chewing and biting.

But beneath the gum lies the hidden foundation: the root. This root is crucial for your oral health. It acts like an anchor, firmly embedded in your jawbone to provide stability and support when you bite or chew.

The Root's Defense System

The root surface itself isn't exposed to the harsh environment of your mouth. It's covered in a hard layer called cementum, similar to enamel but slightly softer.

This cementum protects the underlying dentin, a softer yet sensitive tissue. Dentin contains microscopic tubules that connect directly to the tooth's nerve center.

Signs and Symptoms of Exposed Tooth Roots

Early detection of exposed tooth roots is important for preventing complications. Here are some key signs to watch out for:

Increased Sensitivity:

One of the most common symptoms of exposed tooth roots is increased sensitivity, particularly to hot, cold, sweet, or sour foods and beverages. This discomfort occurs because the dentin, now exposed, contains tiny tubules that transmit sensations directly to the tooth's nerve.

Receding Gums:

Healthy gums should fit snugly around the base of your teeth. If you notice a gap between your gums and teeth, or your teeth appear longer than usual, this could indicate receding gums, a tell-tale sign of exposed tooth roots.

Pain or Discomfort:

In some cases, exposed tooth roots can cause general dental pain or discomfort in the affected area, particularly when biting down or chewing. This pain can be a sign of underlying gum disease or root sensitivity, and the pain can disrupt sleep.

Common Causes of Exposed Tooth Roots

Several factors can contribute to exposed tooth roots. Here's a breakdown of the most common culprits:

Gum Disease:

The leading cause of tooth loss in adults, gum disease weakens and inflames the gums, causing them to recede from the teeth. This exposes the underlying tooth root over time.

Gum disease has two main stages: gingivitis (the reversible stage) and periodontitis (the more severe stage that can damage the bone supporting your teeth).

Plaque Buildup and Bacterial Infection:

Poor oral hygiene allows plaque, a sticky film of bacteria, to accumulate on your teeth and gum line. If left unchecked, plaque hardens into tartar (calculus), which irritates the gums and triggers inflammation.

This inflammation, if not addressed, can eventually lead to gum disease and receding gums.

Other Contributing Factors:

Certain factors can increase your risk of developing gum disease and receding gums, such as poor oral hygiene habits, smoking or tobacco use, a family history of gum disease, aggressive brushing techniques, hormonal changes (pregnancy, menopause), misaligned teeth (crowding, overbite), and chronic teeth grinding (bruxism).

Complications of Exposed Tooth Roots

Ignoring exposed tooth roots can lead to a cascade of problems, including:

  • Increased Risk of Tooth Decay: Exposed tooth root surfaces are not as strong and decay-resistant as tooth enamel. This makes them more susceptible to cavities and tooth decay.
  • Gum Recession and Bone Loss: Untreated gum disease can continue to progress, leading to further gum recession and even bone loss in the jaw. This can compromise the stability of your teeth and increase the risk of tooth loss.
  • Loose Teeth and Potential Tooth Loss: With advanced gum disease and bone loss, your teeth may become loose and eventually fall out.
  • Increased Sensitivity: The exposed dentin contains microscopic tubules that transmit sensations directly to the nerve center of the tooth. This can lead to increased sensitivity to cold, hot, sweet, or sour foods and beverages.

We'll discuss treatment options for exposed tooth roots and preventive measures in the following sections.

Treatment for Exposed Tooth Roots

Early diagnosis and treatment of exposed tooth roots are crucial to prevent complications and maintain a healthy smile. The best course of action depends on the underlying cause and severity of the problem.

Here's a breakdown of some potential treatment options:

Addressing Gum Disease:

  • Deep Cleaning and Scaling: This non-surgical procedure removes plaque and tartar buildup above and below the gum line
  • Antibiotic Therapy: In some cases, particularly with severe gum infections, your dentist may prescribe antibiotics to help control the bacterial growth.

Restoring Lost Gum Tissue:

  • Gum Grafting Surgery: This surgical procedure involves taking a small amount of healthy gum tissue from another area of your mouth or a tissue bank and transplanting it to cover the exposed tooth root.
  • Soft Tissue Grafting: For situations where additional support for the gums is needed, soft tissue grafts can be used

Protecting Exposed Root Surfaces:

  • Dental Fillings: If the exposed root surface is small and doesn't require gum grafting, your dentist may use a tooth-colored filling material to cover the exposed dentin and prevent decay.
  • Dental Crowns: In cases where a significant portion of the root is exposed, or the tooth structure is weakened, a dental crown may be recommended.

Addressing Underlying Causes:

  • Orthodontics: If misaligned teeth are contributing to gum recession, orthodontic treatment (braces or clear aligners) can help reposition the teeth and distribute biting forces more evenly, reducing pressure on the gums.
  • Mouthguards: For individuals with chronic teeth grinding (bruxism), a custom-made mouthguard worn at night can help prevent further damage to the teeth and supporting structures, including the gums.

Preventing Exposed Tooth Roots

The good news is that exposed tooth roots can often be prevented with a consistent and effective oral hygiene routine. Here are some key practices to follow:

Brushing Technique and Choosing the Right Toothbrush:

  • Brush your teeth twice a day for two minutes each time, using a soft-bristled toothbrush.
  • Use a gentle circular motion, focusing on the gum line where plaque tends to accumulate.
  • Consider using an electric toothbrush, which can be more effective at removing plaque than a manual brush.

Flossing Daily and Reaching Below the Gumline:

  • Flossing daily is essential for removing plaque and food particles from between your teeth, where brushing alone can't reach.
  • Use a proper flossing technique to ensure you're cleaning both sides of the tooth and reaching below the gum line.
