What to do if the tooth hurts when it is knocked

Teeth are a very important part of people's body structure. In people's daily diet, the grinding of teeth can promote better absorption and digestion of food. Of course, when problems arise, it will definitely affect people’s normal lives. Although teeth are hard, they are also very fragile. Some people feel very painful when they knock their teeth in daily life. So what are the reasons for this situation? If you feel toothache when you knock your teeth, what method should you take to solve it?

Percussion pain refers to a method of examination in which doctors determine whether a tooth is diseased by tapping the tooth.

Guidance: Because sometimes it is not possible to determine which tooth is hurting, it is necessary to find out by tapping.

1. Common causes of tooth pain

① Dental caries

Initial caries usually have no symptoms. When the caries cavity becomes larger and deeper, toothache may occur when eating. The pain will be aggravated by eating sweets or overcold or overheated food. At this time, you can first use acid-proof and analgesic toothpaste, brush your teeth with warm water, and use folk remedies to relieve pain when necessary, but the most effective treatment method should be to fill the cavities.

② Pulpitis

It is mostly due to pulp infection caused by deep caries without filling, or caused by chemical drugs or temperature stimulation. The pain is spontaneous, paroxysmal and severe, and may be caused by cold, hot stimulation and percussion pain.

If the toothache is caused by pulpitis, you can take ibuprofen orally for pain relief, and use it twice a day.

③ Apical periodontitis

It often spreads from pulpitis to the root canal orifice, causing inflammation of the tissues around the root apex. Symptoms include persistent tooth pain. The affected tooth has a sense of elongation, and is obviously painful to touch and tenderness, and cannot bite food.

At this time, you can take anti-inflammatory and analgesic drugs, such as 0.5 grams of vancomycin No. 4, 3 times a day; 0.4 grams of metronidazole, 3 times a day, 25 mg of indomethacin, 3 times a day; and eat soft food. You can also use folk remedies for emergency pain relief. Root canal treatment should be performed after the inflammation subsides.

④ Tooth trauma

If you accidentally fall, get hurt, or bite sand while eating, your teeth may break or crack, causing tooth pain. You can take anti-inflammatory and analgesic drugs first, or you can use folk remedies to relieve pain. Those who have the conditions should go to the dental department for treatment.

⑤Pericoronitis of wisdom teeth

This disease is generally caused by the difficulty in the eruption of wisdom teeth and poor oral hygiene. At this time, you can take some anti-inflammatory drugs for treatment and pain relief. And the impacted tooth is extracted after the inflammation subsides.

In addition, influenza, trigeminal neuralgia, jaw cysts or tumors, high blood pressure, and heart disease can sometimes cause toothache. Therefore, for those who complain of toothache but have no tooth lesions, do not blindly abuse painkillers. Instead, go to the hospital for specialist diagnosis and treatment in time.

⑥Acute periodontitis

This is mainly because the third molar is in the wrong position, and part of the crown surface is covered by gums, which often cause food to be stuck, easily causing bacterial infection and inflammation, leading to redness and swelling of the gums, persistent pain, sometimes accompanied by sore throat and inability to open the mouth wide. The inflammation around the crown of the wisdom tooth is called pericoronitis.

⑦ Severe tooth enamel wear

Tooth enamel is commonly known as enamel. Because teeth have been responsible for chewing food for a long time, the outermost layer of enamel is gradually worn away, exposing the second layer of dentin. Because there are nerve endings distributed in the dentin, you can feel soreness when exposed to cold, heat or mechanical stimulation.

⑧ Wedge-shaped defect at the cervical region

Due to gum recession and hard toothbrush bristles, the enamel is very thin on the tooth surface close to the gums. The friction of the bristles when brushing often wears off the enamel, and the exposed dentin is softer and is worn into deeper depressions by the bristles, causing soreness.

2. What to do if you have toothache

1. Persistent pain

There is persistent pain in the gums that can be clearly located, a floating sensation in the teeth, and obvious pain when tapping the teeth or biting objects. This indicates that inflammation has invaded the root apex. The treatment is rather troublesome, and the emergency principle is "decompression and drainage" - making a hole in the middle of the tooth to allow the inflammatory secretions to flow out and reduce the pressure in the pulp cavity. After taking X-rays, root canal treatment or plasticization treatment is selected according to the condition.

2. Pain at the root of the tooth

There is persistent pain in the root teeth (wisdom teeth, third molars), and the pain is aggravated by touching the gums. In severe cases, the mouth cannot be opened. If the condition often occurs, the "root teeth" should be extracted after the inflammation is eliminated.

3. Hot, cold, sweet, sour, and painful

Teeth feel pain when exposed to cold, heat, sourness or sweetness. Remove the irritant and the pain will disappear. Pigmentation deposits on teeth, most commonly caries. There is no pigmentation on the tooth surface at the gingival margin, and the defect is deep and wedge-shaped. Both dental diseases are mild and can be improved with restorative treatment. However, if the dentin sensitivity is caused by gum recession, the treatment process is more complicated.

4. Gum pain

Continuous tooth pain, accompanied by redness, swelling, looseness, and often accompanied by symptoms of food impaction, is a manifestation of periodontitis.

5. Spontaneous labor pains

Spontaneous pain in the gums cannot be located and worsens during sleep. Pain can be induced by cold or heat stimulation and persists for a while even after the stimulation is removed. The pain radiates to the ear and temporal area. It means that the dental pulp is inflamed and the "rotten nerve" needs to be treated. After removing the "rotten nerve" of the tooth, root canal treatment can be performed.

6. Pain when biting hard objects

Pain when biting hard objects, and a history of hitting hard objects such as stones. The teeth may have cracks, and in severe cases, the teeth may crack. The treatment plan depends on the depth of the crack: if the tooth is loose, it must be extracted. If it is shallow, it can be retained after a crown is placed.
