What Is Root Resorption?
Many patients are unfamiliar with root resorption (RR), but it is not an uncommon occurrence. In fact, it is found in 5 to 10% of the general population who have never undergone orthodontic treatment (1). So, what is root resorption? Known to affect both baby teeth and adult teeth, the non-infectious process describes when the body mistakenly breaks down the structure of a tooth’s root. It then begins to absorb the tooth, leading to numerous dental health issues. Skip to:

Internal and external root resorption
There are two types of root resorption - internal and external. Internal root resorption is when the damage starts inside of the pulp and slowly deteriorates the tooth from the inside out. In comparison, external resorption occurs on the surface of the tooth, the enamel. This type of damage is much more common.
What does root resorption look like?
There are symptoms of root resorption to be aware of. If any of the following present themselves, seek the assistance of a dental professional. The earlier root resorption is caught, the more likely it is that the tooth can be saved.
- Painful toothache
- Loose teeth
- Red, swollen gums
- Dark or pinkish discolouration
- Tooth movement
Please note that, in most cases, root resorption is asymptomatic. That’s why regular check-ups with your dentist are so important - they will catch problems that are not visible to the untrained eye, and then suggest the appropriate treatment.
Causes of root resorption
The main culprit of root resorption is typically dental trauma, but this isn’t the only cause. The root resorption process could be triggered by something completely out of our control.
CausesExplanation
Blunt force or extreme pressure can damage the root structure of the tooth and weaken the surrounding gums.
Root resorption is often the result of inflammation in the gums or teeth that has reached the tooth pulp.
Orthodontic treatment
The applied force of braces or clear aligners (if too extreme) is recognised to contribute to root resorption.
This action places unnecessary pressure onto the teeth, leading to the breakdown of the enamel.
Systemic diseases
Examples of health conditions associated with root resorption includes Paget’s disease and Gaucher’s disease.
Genetics
Genetics influence the size and strength of teeth. If your enamel is naturally weaker or susceptible to gum disease, the risk of root resorption may be higher.
Treatment for root resorption
You may be wondering, can you reverse root resorption? No. However, dental treatment minimises the chance of further damage and loss of the tooth loss altogether. Here are some recommended treatments:
- Root canal: This restorative treatment is used to address inflammation and/or infection in the tooth’s pulp.
- Dental crown: A great option for repairing and rebuilding a damaged, weakened tooth.
- Calcium silicate cements: Biocompatible materials that help to seal the affected tooth.
- Gum disease treatments: Removes the plaque, bacteria and infection contributing to root resorption.
- Tooth extraction: Used as a last resort if dental treatment has been proven ineffective and nothing else can be done to save the tooth.
How to prevent root resorption
Root resorption poses serious risks to your oral health; therefore, you should do as much as possible to try and prevent it. To minimise the risk of root resorption, try to maintain a good oral hygiene routine. Another tip is to wear a mouthguard if you grind your teeth or play contact sports. As mentioned earlier, try to visit your dentist every year (twice, ideally) and attend regular hygienist appointments. A balanced diet filled with nutrients also supports the health of your bones, teeth and gums, so consider what you are eating in your day-to-day life.
