What materials are used to fill a tooth cavity, and approximately how much does it cost?
The materials commonly used for filling dental cavities include dental amalgam, glass ionomer cement, and composite resin. Their corresponding prices are: dental amalgam, 100–300 yuan per tooth; glass ionomer cement, 150–400 yuan per tooth; composite resin, 200–500 yuan per tooth. Factors affecting material costs include the extent of tooth decay, dentist qualifications, and regional differences.

Principle of Treatment |
Mixed dental amalgam is packed into the prepared cavity. |
The material is mixed and filled into the cavity, where it chemically reacts with calcium ions in the tooth structure to achieve chemical adhesion to dental tissues. |
The cavity is cleaned and etched to roughen the surface, a bonding agent is applied, and composite resin is placed in layers and cured with light. |

Analysis of influencing factors:
1. Extent of tooth decay: If decay is mild and only superficial decayed tissue needs removal before simple filling, the cost will be relatively low. However, if decay has reached the dental pulp, root canal treatment must be performed prior to filling, which increases the overall cost.
2. Dentist qualifications: Experienced and skilled dentists can provide more accurate diagnosis, better treatment planning, and precise procedures, which may result in higher fees compared to general practitioners.
3. Regional differences: In economically developed regions, higher living costs lead to correspondingly higher dental treatment prices.
After cavity filling, potential complications such as tooth sensitivity or material dislodgement may occur. It is recommended to maintain good oral hygiene, avoid biting hard objects, and attend regular dental check-ups. Patients should seek treatment at reputable medical institutions under the guidance of qualified dental professionals.
