When a patient has a cavity, they may only occasionally experience pain. In such cases, it is generally recommended that the patient visits a hospital for consultation. Even a minor cavity has its preventative measures to stop it from worsening and leading to severe consequences; therefore, treatment is still necessary. Many severe cavities develop from minor ones. They can slowly cause defects in the teeth, damage to the tooth root, or stimulate the nerves in the gums, potentially leading to loose or falling teeth. Thus, it is advisable for patients to adopt the correct treatment methods. Additionally, if patients experience pain, they can undergo anti-inflammatory and pain relief treatments to alleviate discomfort and avoid inconvenience in their dietary life.
