### Understanding Root Cavities Root cavities are a type of tooth decay that affects the root of the tooth. They can develop without you noticing, especially if you're older. Here's what you need to know about their causes, treatment, and prevention. #### Causes Root cavities occur when bacteria in your mouth produce acids that erode the enamel and reach the root. This process starts with plaque, a sticky film that forms on your teeth when bacteria feed on sugars and starches from food. If not removed, plaque can harden into tartar, making it easier for bacteria to reach the root. #### Symptoms You might not see root cavities by looking in the mirror, but you could feel some pain or sensitivity, especially to hot or cold foods. Receding gums can also expose the roots, making them more vulnerable to decay. #### Risk Factors Older adults are more prone to root cavities due to gum recession and conditions like periodontal disease. Chronic illnesses like diabetes can also increase the risk. Smoking and poor dental hygiene are additional risk factors. #### Treatment If you have a root cavity, don't delay treatment. A dentist will remove the decayed area and fill it. In severe cases, a root canal may be needed to remove damaged pulp and seal the tooth. A crown might be placed over the tooth to strengthen it. #### Prevention Good dental hygiene is crucial. Brush your teeth twice a day with fluoride toothpaste and use a fluoride mouth rinse. Regular dental check-ups can catch problems early. Professional fluoride treatments can also help. #### Conclusion Root cavities can develop before you realize it, especially if you're older. Practicing good dental hygiene and getting regular check-ups can help prevent them. If you're at higher risk, talk to your dentist about preventive treatments.
