A filling is not a very painful procedure; that’s why it doesn’t take a lot of time. However, patients with sensitive teeth might feel a bit of pain while getting a dental filling. The area of decay also plays a significant role in deciding the time taken to get a filling. Molars are located deep inside the mouth, and it is not easy to fill gaps in such parts. Alternatively, if there is a decay in any incisors, then the filling won’t take long. There are two types of filling, namely direct filling, and indirect filling. Metal fillings and Amalgam fillings fall under the category of Direct filling. Direct fillings are completed in a single dental appointment. At the same time, Indirect fillings take more than one appointment.

The patient might feel a bit of soreness in the area where the filling is applied.

Also, if a patient starts eating immediately after getting a filling, it might be excruciating, and the filling may come out.

Teeth are one of the most crucial body parts, and it is essential to give proper care to them. Negligence results in decay or cavity, and a filling is used to treat it. If a filling is not applied immediately to the affected area, then the decay starts spreading.

Various fillings are available, and the amount of decay is the deciding factor while choosing the filling. On average, a filling takes twenty minutes to an hour, and the patient can start eating liquid or semi-solid food after eight hours. It is advised to seek medical assistance in case of any emergency.
