Cracked fillings require radiographs to check the depth of the crack, and after removing the old filling material with an instrument, consider re-preparing the cavity for filling or crown restoration.
Cracked fillings can lead to microleakage and secondary caries, which requires the use of specialized instruments to remove the original filling material, re-prepare the cavity for the cracked area, and re-fill the restoration with resin. If the cracks are wide and deep after examination, crown protection should also be considered to prevent the tooth from fracturing.
If a filling is cracked, it is recommended to seek medical attention in time to avoid deepening of the cracks, which may lead to pulpitis and pain. It is also recommended to conduct regular oral examination, found that the problem is dealt with in a timely manner.
