Whether a tooth is replaced or implanted depends on the condition of the tooth. If the lost area is not large, generally fillings can be; if a large area or a whole lost, generally consider dental implants. If the tooth is only partially knocked down accidentally and the nerve of the tooth is not exposed, you can choose to fill the tooth; a filling is a localized filling that restores the shape and function of the tooth. Secondly, if the tooth is a large area or a whole tooth loss can not retain the affected tooth, you can consider that the extraction that is planted, you can avoid alveolar bone resorption, to avoid damage to neighboring teeth, to restore the ability to chew normally. So the tooth loss filling or dental implants, need to be analyzed according to the actual situation of the patient. It is recommended that the patient go to the dentist in time, after the doctor is clear, give targeted treatment; and pay attention to not eat too hard food and too sticky food.
