Yes. You don't need to have the original fragment for a dentist to repair many chipped teeth. Depending on the damage, tooth-colored filling material can be used to replace the missing section. We'll assess the remaining enamel and recommend a repair that suits the tooth. 

 Yes. When enamel breaks away, the layer beneath it, called dentin, may become exposed. This can make the tooth react to cold drinks, sweet foods, or even air. If sensitivity develops after a chip, arrange an examination so we can check whether the exposed area needs treatment. 

 Many small chips can be repaired in a single visit, particularly when composite bonding is suitable. More extensive damage may require additional appointments for a custom restoration. We'll explain the proposed procedure and expected number of visits after examining your tooth. 

 A very small enamel chip may not require extensive treatment, but some damaged teeth can become more vulnerable to further breakage or sensitivity. The risk depends on the chip's depth and location. A dental examination can help establish whether smoothing, bonding, or another repair is needed. 

 Often, yes. Your dentist will check whether the existing filling is secure and how much healthy tooth remains. Sometimes the damaged filling can be replaced or repaired. If the surrounding tooth has weakened, a crown or another restoration may provide better support.
