A gum check involves a thorough examination of the teeth and gums. Some discomfort and bleeding from the gums can be expected as the dentist checks for gum disease. If required, the dentist may suggest taking x-rays to determine the level of bone supporting your teeth. This is the essential first step in achieving healthier gums. With an accurate assessment, the dentist will be able to tell you whether you have gum disease and propose a suitable course of treatment.
