What is the reason for sore teeth?

It is not uncommon to have sour and soft teeth, especially when eating sour, spicy and irritating foods. The symptoms of sour and soft teeth will be more obvious, and some may be accompanied by pain. Therefore, it is necessary to understand the reasons. Some teeth are prone to allergies, so they are prone to become sour and soft.

1 When patients feel their teeth are sore and soft, this feeling mostly comes from the dental nerves in the patient's dental pulp. Normally, human dental pulp nerves are not easily stimulated by the outside world. However, the structure of human teeth determines that there are some tiny holes on the dentin itself. Some substances that can cause allergies can invade the dental nerves through the holes and cause tooth allergies.

2 Normally, the holes on the dentin do not allow foreign substances to easily enter the dental nerves. However, due to some reasons, such as the wear and tear of teeth caused by daily life, chewing food or improper use of toothbrushes, these holes will eventually become larger, making it easier for foreign substances to enter these holes.

3. When foreign substances enter the tooth cavity, they will directly stimulate the dental pulp and dental nerves, causing the patient's teeth to feel sore and soft. Therefore, in order to avoid the sore and soft feeling of teeth caused by tooth allergies, patients must use the toothbrush correctly and do not eat too hard food.

4. In fact, these holes may cause tooth allergy not only due to normal wear and tear, but also due to caries or frequent consumption of acidic substances that cause continuous corrosion of the teeth. Therefore, if the patient feels sore and soft teeth, he should try not to eat corrosive foods.
