If the tooth is half hollowed out by decay, whether it can be filled needs to be judged based on the specific situation.

If the tooth decay has not damaged the tooth root, and if half of the tooth is lost and has not affected the tooth nerve, tooth root, etc., you can generally consider filling the tooth. Clinically, for cases with large dental tissue defects, root canal treatment and dental crowns are generally performed to protect the teeth and promote the recovery of tooth function. Root canal treatment mainly removes necrotic material in the root canal, fills it, and disinfects it to prevent the occurrence of apical periodontitis.

If the tooth decay is severe, the tooth root has been damaged, or there is little remaining tooth tissue, fillings are generally not recommended. At this time, the tooth may have lost the conditions for root canal treatment and crown, and the tooth may not be filled. In this case, implant treatment after tooth extraction is generally considered. Implant therapy is a treatment method that uses artificial implants implanted in bone tissue to restore the shape and function of teeth.

Therefore, when a tooth is half hollowed out by decay, a doctor needs to judge whether it can be filled. In daily life, you need to pay attention to the cleaning of the oral cavity and avoid eating foods that are too hard or too sweet that can easily damage teeth to prevent tooth decay. At the same time, once tooth decay is discovered, early treatment and intervention are required to avoid further damage from tooth decay.
