What should I do if a small piece of my gum is missing?

Teeth development is a lengthy process. Initially, the tooth crown forms within the alveolar bone—a structure medically termed the “tooth germ.” Once the tooth germ reaches a certain stage of development, the root begins to form. As the root grows, the crown gradually moves toward the occlusal surface and exerts pressure on the alveolar bone above it. So, what should you do if a small portion of your tooth is chipped or missing?

What to Do If a Small Portion of Your Tooth Is Missing

The appropriate treatment for a minor tooth defect depends on the specific condition of the tooth. If the damaged area affects aesthetics and the defect is relatively minor, inlay restoration may be suitable. For more extensive tooth loss accompanied by noticeable sensitivity to hot or cold stimuli, restorative filling is required to seal exposed dentinal tubules; light-cured composite resin is commonly used for such repairs. If the restored area remains unsatisfactory, full-contour porcelain crowns may be considered. In cases where pulpitis arises secondary to the defect, comprehensive root canal therapy is typically necessary, followed by full-coverage crown restoration of the non-vital (pulpless) tooth.

We recommend using the Bass brushing technique—endorsed by the Chinese Stomatological Association—to effectively remove food debris and soft plaque from the gingival sulcus. Without these residues, bacteria cannot metabolize them into toxins that irritate the gums, trigger gingivitis, or cause gingival bleeding. Additionally, brushing should be performed after each meal and before bedtime to ensure thorough oral hygiene and prevent gingival bleeding.

In daily life, cultivating healthy lifestyle and dietary habits is essential. We hope this information proves helpful to you.
