Because it is impossible to directly fill the cavity during treatment, but to clean the decayed surface, the first step of all dental restoration work is to clean the decayed surface. In the process of cleaning, sometimes the decayed surface is close to the pulp nerve cavity, that is, the teeth have become very thin, so the pulp nerve cavity can only be opened for further treatment.
After the dental pulp nerve cavity is opened, it can't be directly repaired, because the nerve cavity is directly closed, on the one hand, the filling material is easy to fall off, and on the other hand, during the chewing process of patients after filling teeth, the dental pulp nerve will cause severe pain, so it is necessary to kill the dental pulp nerve most of the time to avoid the unbearable pain of patients after filling teeth.
However, now skilled dentists will take the treatment of pulpotomy for patients, that is, kill the pulp that is most likely to be close to the tooth restoration surface, while completely retaining the pulp. This treatment method can not only restore the teeth normally, but also not easily cause the root to crush or fall off because there is residual pulp, and it can also retain the toughness of the teeth. Vital pulp amputation is difficult to operate, has a long treatment cycle and limited success rate, and has not been widely used at present.
1. It doesn't matter if you brush your teeth a little, but don't chew food and hard objects with your newly filled teeth. Generally, it is advisable to chew food on the affected side on the second or third day after filling teeth, so as to avoid tooth fracture and filling material falling off.
2. Different materials have their advantages and disadvantages. It is estimated that yours is filled with amalgam, and the amalgam will completely harden after 24 hours, so please don't chew food with the affected teeth within 24 hours to avoid the filling falling off.
3. If you have slight pain after filling your teeth, you can go to self-observation first, and some slight discomfort and pain can disappear by yourself. If the pain is not relieved, but further aggravated or occurs, such as biting pain, jumping pain, cold and hot stimulation pain, spontaneous pain at night, etc., you should go to the hospital for further examination and treatment in time to find out the reasons and eliminate the pain. Moreover, it is normal to have bloodshot saliva within 1 week, and the pain in the tooth extraction area is gradually normal. Don't repeatedly suck and spit out blood clots because of the smell of blood in your mouth, which will lead to wound healing.
Maybe it's tooth decay. Maybe you didn't like brushing your teeth before. Just remember to wash your teeth often in the future.
Either trust your doctor or see another doctor again.
6. For the yellow teeth you mentioned later, you can choose salt white toothpaste and tooth fixation. Many brands can choose from, and after using it, they feel good, which stabilizes a brand.
7. Dental caries should be treated according to the degree. Generally, small holes do not need to kill nerves. Nerve killing is harmless to human body, but the teeth after nerve killing will gradually turn black and brittle. Generally, in regular hospitals, normal treatment will not damage facial nerves and cause sensory damage. In addition, it is necessary to protect other teeth after curing, brush your teeth after three meals a day and after eating sweets, and pay attention to protecting your teeth during strenuous exercise.
In addition, you must find a clean and regular clinic for tooth cleaning, because many diseases can be spread during tooth cleaning, including AIDS! Try to floss yourself often.

I wish you a speedy recovery! Have beautiful teeth and a good mood!
