What is the reason for pain after tooth filling

Teeth are very important to the human body. A beautiful set of teeth can not only improve people's image, but also is a symbol of people's physical health. Many people do not pay attention to cleaning their teeth, and there is often tartar in their teeth. Over time, it will cause tooth decay, and at this time, fillings are needed. But some people experience pain after having a filling. So, what is the reason for pain after a tooth filling?

Dental filling is the most common method of restoring teeth. Some patients experience pain after filling a tooth. What is the reason for pain after filling a tooth?

(i) Bite pain after filling: This is common in two situations: (1) Most of the time, the filling has early contact points, which cause periodontal trauma. Examination can show bright spots on the surface of silver-mercury fillings. For fillings made of other materials, early contact points can be determined using articulating paper.

(2) Pain when biting the teeth. This happens when the filling material is not compacted or has bubbles or cavities inside, or when the bottom padding material that protects the dental pulp is not properly placed. Treatment methods: The first method is to simply adjust the jaw; the second method requires removing clean filling materials and re-filling the tooth.

(2) Symptoms of hot and cold allergies after filling: Generally there are three situations

(1) Excessive heat generation during grinding or disinfectant stimulation of the dental pulp can aggravate the symptoms of hot and cold sensitivity or turn into spontaneous pain.

(2) The base is not laid or the base is not laid well, and the filling material irritates the pulp: the base material itself irritates the pulp.

(3) The filling material is sunken or the remaining tooth is bitten off, exposing the pulp and causing symptoms of sensitivity to cold or heat.

(4) Caused by a tiny gap between the filling material and the edge of the tooth. Treatment method: If there is no spontaneous pain, you can clean the materials and re-fill the tooth. If you feel obvious pain, you should not fill the tooth for the time being, but calm down and observe.

(III) There is provocative pain and spontaneous pain after filling; there are two situations

(1) Most of the recent cases are pulpitis cases that were misdiagnosed as deep caries or accidental pulp penetration that went undetected. Treatment: There is no solution in this case and the filling material needs to be removed for pulp treatment.

(2) Long-term pain or biting pain is often caused by secondary caries complicated by pulpitis or pulpitis or pulp necrosis caused by irritation of the pulp by the filling material. Treatment method: The filling material needs to be removed and complete pulp treatment is performed.

(iv) Bite pain and gingival bleeding after filling: poor contact between the filling material and the adjacent teeth causes food to be stuck, or the adjacent filling material has an overhang that presses on the gums, which can lead to gingivitis or periodontitis. Treatment method: If simple jaw adjustment can improve the condition, that would be best; otherwise, new fillings are needed to restore the shape.
