Introduction
During the filling procedure, the tooth may experience pain when exposed to stimuli such as heat, cold, acidity, sweetness, or spiciness due to irritation from dental instruments and filling materials. This type of pain occurs after the filling. Within two or three days following the procedure, the pain will gradually diminish and disappear. If the pain persists for a longer duration, some anti-inflammatory medication can be taken.

In daily life, some people develop dental caries. After receiving dental fillings, they may experience severe pain. What causes toothache after a filling?

What Causes Toothache After a Filling?

Tooth pain following a filling is quite common and mainly caused by several factors. First, during the filling procedure, the tooth may become sensitive due to stimulation from surgical instruments and filling materials. When exposed to hot, cold, sour, sweet, or spicy stimuli, this sensitivity can lead to pain. Such pain typically occurs shortly after the filling and usually gradually diminishes and disappears within two to three days. If the discomfort lasts longer, patients may take anti-inflammatory medications. However, if the filling material continuously rubs against the dental nerve, causing inflammation of the nerve and resulting in pain, root canal treatment may be necessary.

Commonly used filling materials include glass ionomer and composite resin. Composite resin, in particular, is widely used in clinical practice because its color closely matches natural teeth and it has high moldability. It is also more cost-effective and can be quickly and easily applied in the mouth. After the procedure, recovery is generally straightforward with observation, effectively reducing the patient's overall treatment time.

During the recovery period, avoid eating spicy or irritating foods. Focus on consuming fresh fruits and vegetables, and stick to liquid or soft foods for a short time. Additionally, maintain good oral hygiene practices. We hope this information is helpful to you. Wishing you good health and happiness!
