Yes, receding gums can cause cavities. When the gums recede, the tooth roots become exposed, which are more vulnerable to decay than the enamel on the tooth crown. This exposure can lead to decay in the tooth’s root surface, which can cause cavities. Receding gums can be caused by various factors, such as gum disease, brushing too hard, or aging. Maintaining good oral hygiene and visiting a dentist regularly can help prevent gum recession and cavities.
