Prevention is better than cure, as anyone who has suffered toothache will tell you. Tooth decay can result in crowns, fillings or inlays, and dental nerves may even become diseased, leading to an abscess, requiring root canal treatment or extraction.To avoid potential dental problems before they take hold, it’s vital to maintain a daily routine that will keep your teeth and gums healthy, including regular brushing and flossing. It’s also important to be aware of symptoms that may indicate underlying dental issues.
