Understanding Root Resorption: Causes, Diagnosis & Treatment in Glen Iris

Root resorption is a process in which the tissues surrounding a tooth begin to break down the root surface and replace it with soft tissue. This destructive process can affect both children and adults, and because it is usually painless, it often goes unnoticed until a dental X-ray reveals the problem.

What Causes Root Resorption?

Several factors can trigger root resorption:

1. Trauma or Injury

A blow to the mouth or an accident can damage the tissues around a tooth. During healing, the body may mistakenly break down part of the root.

2. Internal Resorption

Inflammation inside the pulp chamber can lead to the body attacking the tooth from the inside out. This is often discovered incidentally on routine X-rays.

3. Gum Disease

Severe periodontal inflammation may cause the body’s immune cells to misidentify the root surface as a foreign object, resulting in external resorption.

4. Orthodontic Treatment

Braces and aligners apply pressure to move teeth. In some patients, this can lead to a shortening of the roots over time.

5. Pressure From Nearby Teeth or Cancer

The eruption of canines or wisdom teeth, or the presence of a cancer, can press against neighboring teeth and trigger resorption.

Why Early Detection Matters

Because root resorption is typically painless, it may progress silently for months or years. Routine dental X-rays are essential to detect it early.

Once identified, determining the cause is critical. By removing or treating the underlying reason—whether inflammation, pressure, or trauma—we can often stop the resorption and preserve the affected tooth.

If left untreated, however, resorption can progress to the point where the tooth may need to be extracted.
