Cavities can also be treated with teeth cleaning. Firstly, a cavity is a type of dental caries, a tooth condition caused by tissue infection. Generally, it is accompanied by pain. Teeth cleaning is needed when there is a significant build-up of tartar around the teeth, which if not promptly cleaned, can lead to gingivitis and even periodontitis, potentially causing tooth loss. During cavities, teeth cleaning can be performed. However, teeth cleaning involves ultrasonic removal of tartar around the teeth. If the cavities are deep, the cleaning process may cause discomfort or severe pain. Therefore, it is necessary to treat the cavities first before proceeding with teeth cleaning to avoid significant pain during the cleaning process.
