1. Avoid damaging the dental bone: A detailed examination of the alveolar bone and soft tissue around the tooth before restoration can avoid damaging the dental bone.
2. Complete and effective restoration: The tooth preparation tools used by dentists have been carefully designed to ensure that the damaged tooth tissue can be removed in a targeted manner without damaging the surrounding tooth bones.
3. Reduce the sensitivity of teeth to heat: In the process of tooth preparation, dentists will also use cooling liquid to cool teeth and tools to reduce the heat generated during cutting.
