Tooth sensitivity after fillings

Most people have cavities because the human body needs to replenish sugar. Especially when living standards gradually improve, some children are simply obsessed with eating sugar. However, if you eat too much sugar, you are prone to tooth decay. Tooth decay is a disease that can cause toothache. It eats away the teeth of the human body. If the condition is too serious, you need to fill the teeth. However, some people find that their teeth are very sensitive after filling. What's going on?

I believe everyone knows the importance of teeth to us. If there is a problem with our teeth, it will not only cause us pain but also affect our speaking and eating. Therefore, we must pay attention to the health of our teeth in our daily lives. Once there is a problem with the teeth, we must deal with it in time. Some friends need to have their teeth filled due to dental problems. After the filling, the teeth are prone to sensitivity. Below we will introduce the reasons for tooth sensitivity after filling.

(1) The patch is missing or falling off

The defect or fall-off of filling materials after filling is more common in adjacent cavity fillings, and the filling materials may fall off completely or be partially defective. The defect of the filling material may cause the tooth cavity or pulp corner and other sensitive areas to be exposed, which will cause pain after being stimulated by cold or hot food. There are several reasons why fillings may be damaged or fall off: ① The filling is in close contact with the tooth tip and is subjected to chewing force, resulting in breakage or fall off. Medically known as overfeeding. The clinical manifestations of excessive filling material are: the filling material is shiny (silver-mercury alloy). After filling with composite resin and other resin materials, the articulating paper can be used for coloring inspection. The area where the filling material is too high is darker. ② Chewing food before the supplement is completely solidified causes the supplement to break. ③The tooth cavity has no retention, resulting in complete fall-off of the filling material. ④ The cusp of the opposing tooth is too long and bites off the filling material.

In clinical treatment of patch defect or fall-off, the cause of the defect or fall-off should be found out first. If the tooth tip is too long, grind it. If the tooth cavity has no retention, retention should be made, and root canal retention should be used if necessary.

(2) Pain from electrical stimulation

Patients who experience pain from electric current stimulation feel a sensation like an electric shock. The cause of this pain is generally believed to be due to simple silver-mercury alloy filling.
