1. Preparation before grinding teeth: First, inject anesthetic into the gums to prevent pain when grinding teeth. After the anesthesia takes effect, start grinding the teeth evenly in circles, except for the part that touches the gums.

2. After grinding the teeth, use a specific mold to take an impression of the teeth, and then put a temporary plastic brace on the teeth until the porcelain teeth are processed.

3. The next step is color comparison. The doctor will use a color chart to compare the color of the teeth in the patient's mouth to see which color is closer to the color of the teeth themselves, and then use this color for the porcelain teeth.

4. After the porcelain teeth are finally processed, the doctor will remove the temporary braces and install the porcelain braces on the teeth. At this point, the entire process of porcelain tooth restoration is over, and all that is left is regular follow-up visits.
