### What is External Resorption? External resorption is a dental condition where the outer surface of a tooth starts to break down. This can lead to chipped, broken, or damaged teeth. It's more common than internal resorption, which affects the inside of the tooth. ### Causes External resorption can be caused by several factors, including: - **Trauma:** Injuries to the teeth can trigger resorption. - **Orthodontic Treatment:** Braces and other dental devices can sometimes cause resorption. - **Inflammation or Infection:** Gum disease and other infections can lead to resorption. - **Pressure:** Cysts or tumors in the mouth can put pressure on teeth, causing resorption. ### Symptoms In the early stages, you might not notice any symptoms. However, as the condition progresses, you may experience: - **Chipped or Broken Teeth:** Visible damage to the teeth. - **Holes in Teeth:** Small holes may appear on the tooth surface. - **Flattening of Roots:** X-rays may show that the roots and root tips are flattening. ### Diagnosis Regular dental check-ups are crucial for early detection. Dentists use X-rays to identify signs of external resorption. Comparing new X-rays with older ones can help in diagnosing the condition. ### Treatment Treatment depends on the extent of the damage: - **Minor Damage:** The affected area can be repaired to prevent further damage. - **Root Canal:** If the root is affected, a root canal can remove infected tissue and restore the root structure. - **Calcium Hydroxide Paste:** This can be applied to remineralize the tooth. - **Extraction:** In severe cases, the tooth may need to be extracted and replaced with an implant or veneer. ### Prevention You can take steps to prevent external resorption by: - **Regular Dental Check-ups:** Early detection is key to preventing severe damage. - **Good Oral Hygiene:** Brushing and flossing regularly can help prevent infections and inflammation. - **Protective Gear:** Wearing mouthguards during sports can prevent trauma to the teeth. ### Conclusion External resorption is a progressive condition that can cause significant damage if left untreated. Regular dental visits and good oral hygiene are essential for early detection and treatment.
