The wisdom tooth was extracted and the cavity is smelly and bitter

Some people feel a very smelly and bitter taste in their tooth cavity a few days after having their wisdom teeth removed. This may be because the dental nerve in the cavity has died or the odor is emitted by food residues in the cavity. It is recommended to go to the hospital for root canal treatment, which is to remove the necrotic dental nerve and the decay in the tooth cavity, and then perform anti-inflammatory treatment. In addition, to prevent the tooth cavity from smelling bad after tooth extraction, you must rinse your mouth after meals, and it is best to rinse with salt water.

1. Why do tooth cavities smell and taste bitter?

It is suspected that the cavity of this tooth has rotted to the dental nerve, and the odor is caused by the necrosis of the dental nerve. In addition, some food residues in the cavity cannot be cleaned out in time, which will also cause the odor. It is recommended to see a doctor for root canal treatment as soon as possible, which is to remove the necrotic dental nerve and the decay in the tooth cavity, and then take anti-inflammatory measures. After the inflammation subsides, fill the cavity again. This will completely solve the problem of toothache and odor.

2. What to do if the tooth cavity is smelly and bitter

1. It takes about one month for the tooth cavity to heal completely (depending on individual circumstances).

2. It may be the odor of food residues, so keep your mouth clean. Foods should be cleared out to avoid inflammation.

3. Rinse your mouth after meals (rinse your mouth, not brush your teeth). The remaining food debris will fall out when you rinse your mouth. If it doesn’t fall out after a few times, you can also choose to plug the tooth cavity with a small ball of cotton before eating and remove it after the meal.

4. 3 to 5 days after the removal of wisdom teeth, the alveolar socket becomes empty, has a noticeable odor, and is severely painful. This is dry socket and you need to go to the oral department of the hospital for local flushing to clean the inflammatory necrotic tissue in the alveolar socket, and then fill it with iodine form gauze. This will significantly relieve the symptoms of pain. If the pain is severe, you can undergo further treatment until the extraction wound heals.

3. Degree of caries

1. Shallow caries

Also known as enamel caries, caries is limited to the enamel. In the early stage, it appears as chalky patches caused by demineralization on the smooth surface, which later become yellow-brown due to coloring. The pits and fissures appear diffuse and ink-soaked. Generally, there are no obvious cavities, only a rough feeling when probing. In the later stage, shallow holes limited to the enamel may appear, with no subjective symptoms and no response to probing.

2. Medium caries

Caries has reached the superficial layer of dentin. Clinical examination shows obvious cavities. There may be tenderness on probing. There may be pain reaction to external stimuli (such as cold, heat, sweet, sour and food embedded in the teeth). The pain disappears immediately when the stimulus is removed. There is no spontaneous pain.

3. Deep caries

Caries has reached the deep layer of dentin, generally manifesting as large and deep cavities, or small entrances with more extensive damage in the deep layers. The reaction to external stimuli is more severe than that of moderate caries, but after the source of stimulation is removed, the pain can still be relieved immediately, and there is no spontaneous pain.
