What Is Internal Resorption?
Internal resorption is a rare condition where the body’s own cells begin to break down and absorb the internal structure of a tooth—specifically the dentin and inner root canal walls. It often occurs without pain or visible symptoms until significant damage has already occurred. In most cases, internal resorption is discovered during a routine dental X-ray. If left untreated, it can lead to structural weakening, infection, or tooth loss. At 3D MicroEndo, we specialize in diagnosing and treating internal resorption using advanced imaging and precision root canal therapy to stop the damage and preserve the tooth.
What Causes Internal Resorption?
Internal resorption is most often the result of trauma to the tooth or long-term inflammation of the pulp. It can also follow certain dental procedures or develop without a clearly known cause.
Common causes include:
- Dental trauma or injury
- Long-standing untreated cavities or pulpitis
- Orthodontic movement or pressure
- Chronic inflammation within the pulp
- Occasionally, unknown factors (idiopathic cases)
Because the process is usually silent, regular dental checkups and imaging are key to early detection.
Symptoms of Internal Resorption
Many patients experience no symptoms at all. However, depending on how advanced the condition is, you may notice:
- A pinkish discoloration inside the tooth (known as a “pink tooth”)
- Tooth sensitivity or mild pain
- Unexplained changes in tooth color
- Weakening or thinning of the tooth
- Evidence of damage on dental X-rays
If the resorption progresses to the root or outer structure, it can compromise the tooth’s integrity and lead to infection or fracture.
How We Treat Internal Resorption
The goal of treatment is to stop the resorptive process, eliminate any infection, and stabilize the tooth to prevent further damage.
Step 1: Comprehensive Imaging & Diagnosis
We use CBCT (cone beam CT) scans and digital X-rays to assess the extent and location of the resorption.
Step 2: Root Canal Therapy
If the resorption is confined to the pulp space, a root canal is performed to remove inflamed tissue and fill the resorptive defect with biocompatible material.
Step 3: Restoration
Once the tooth is stabilized, your general dentist may place a crown or other restoration to protect and strengthen it long-term.
Step 4: Monitoring
We follow up with periodic imaging to ensure the tooth remains stable and no further resorption occurs.

Frequently Asked Questions
No, it’s relatively rare and usually discovered during routine dental imaging.
No. Once it starts, it must be treated professionally to stop the breakdown of the tooth’s structure.
Yes, root canal therapy is typically the recommended treatment to stop the resorption process and preserve the tooth.
You likely won’t have symptoms early on. It’s usually diagnosed through X-rays or CBCT scans during a dental exam.
The resorption may continue, weakening the tooth, causing infection, or leading to eventual tooth loss.
