What is Internal Resorption?
When dental trauma happens, a rare condition known as internal resorption can occur. This resorption begins inside the tooth and eventually destroys its entire structure.
Your teeth get their strength and health from cells known as odontoblasts that work to create dentin. Often after dental trauma, these cells can begin to malfunction and cause erosion in the tooth – from inside the tooth. With diagnostic testing, this condition can be discovered and treated using a specifically targeted procedure designed to clean out the root canal system. Then, calcium hydroxide is used to get rid of these disorganized cells. The tooth is sealed up and strength is restored.
If the internal resorption goes unnoticed and untreated, it can cause teeth to weaken and easily break.
Symptoms of Internal Resorption
While many people don’t experience any symptoms with internal resorption, there are a few things you may look out for:
- A brittle tooth that chips easy
- A cavity-type hole in the tooth
- Discoloration in the tooth – such as a dark or reddish/pink area
Keep in mind that the erosion takes place inside the tooth which makes it hard to detect without diagnostic imaging.
