Why does tooth acid occur when brushing teeth

Teeth are the hardest part of the human body, but also the most sensitive and at risk of disease. Many people feel that their teeth are very sour when brushing their teeth. In fact, this is an abnormal phenomenon, which indicates that there are certain problems with the teeth, such as tooth cracks, caries, wedge-shaped defects, dentin hypersensitivity, periodontal disease, acid reflux tooth sensitivity and menstrual tooth sensitivity.

Cracked tooth

Also known as microcracks, they are small cracks that appear on the surface of the crown due to long-term chronic damage. It is common to occur in teeth grinding. The scary thing is that there are often no symptoms in the early stages. When the cracks penetrate into the dentin layer under the tooth surface, it will cause tooth soreness and pain when biting things. Spontaneous pain will only occur when the pulp is infected, and eventually tooth splitting and tooth loss may occur.

Dental caries

In fact, it is what we often call "rotten teeth", which is the most common chronic disease. If you have dental caries, you will feel soreness and weakness when brushing your teeth, drinking hot water, and chewing food. This means that the caries has developed to a medium depth. When the caries develops deep and close to the pulp, the sensitive symptoms will be very obvious, and even pain will occur under cold or hot stimulation.

Wedge-shaped defect

Wedge-shaped defects in teeth sound complicated, but they are actually caused by incorrect brushing methods, which mechanically damage the neck of the tooth and cause defects. This exposes the dentin layer, which is easily affected by external stimuli, especially the change in temperature, resulting in sensitive symptoms. It should be noted that when spontaneous pain occurs, it means that the damage has developed deep into the pulp and caused pulpitis.

Dentin hypersensitivity

Sensitive symptoms occur due to the exposure of the second layer of dentin of the teeth and the opening of dentinal tubules. There is no spontaneous pain, and the teeth are particularly sensitive to temperature changes and the stimulation of chewing and biting. Multiple teeth may experience this condition at the same time.

Periodontal disease

When periodontitis develops to the middle and late stages, the alveolar bone is absorbed, causing the gums to shrink and the root surfaces to be exposed. The root surfaces of teeth that have lost their protective function are prone to sensitivity when exposed to cold or hot temperature stimulation. The symptoms are also characterized by soreness and weakness in multiple teeth or the necks of all teeth in the mouth, and a noticeable sense of weakness when biting things.

Acid reflux tooth sensitivity

Digestive tract diseases can also cause sore teeth. Patients with acid reflux esophagitis often suffer from tooth sensitivity at the same time. This is because the refluxed gastric acid corrodes the teeth in the mouth, causing decalcification of the tooth surface, making the teeth extremely sensitive to external stimuli. The characteristic is a history of acid reflux. The symptoms are more obvious on the inner tooth surface of the mouth when rinsing the mouth with cold water or eating hot, cold, sour or sweet foods.

Tooth sensitivity during menstruation

This condition is often seen in young women. Weng Zhiqiang said that some female patients he met in the outpatient clinic said that they always felt sore and sensitive teeth during menstruation, and had difficulty chewing. The location of the teeth was uncertain and the symptoms varied from mild to severe. However, no sensitive teeth can be found during clinical examination. This may be related to the impact of changes in hormone levels in the body during menstruation on the oral environment or mental anxiety during menstruation.
