() "Doctor, I'm not here to extract my teeth, and there's no tooth pain." Grandma Zheng pouted, raised her upper body, and asked worriedly, "I just want to ask, is it normal for me to have teeth at my age?"

Qian Hao is the only dentist in the only dental defense center on Pearl Island. Sixty percent of the residents on the island have visited the teeth here. He clearly remembers that there was no tooth left in Grandma Zheng's mouth.

"Grandma Zheng, it's not unusual for you to have teeth at this age. It's called burying teeth or having tooths. It's quite common, don't worry." Qian Hao smiled and patted the back of the treatment chair, "Lying down first, I'll take a look for you."

Grandma Zheng lay down obediently, Qian Hao stepped down, raised the treatment chair to the appropriate position, and pulled down the round mirror on his forehead.

"Don't be nervous, it's okay." Qian Hao comforted while pulling his mask. Although a person's age is proportional to his experience, in this industry, patients no matter how old they are, they have to be coaxed by their children. "Come on, open your mouth, ah-"

Before the stick was inserted into Grandma Zheng's mouth, Qian Hao had already seen the four teeth exposed under her lips.

...

The newly grown teeth of the elderly are usually very small. Usually, it is because they are occupied by other teeth and cannot grow normally for a long time. However, the four teeth of Grandma Zheng...

"Grandma Zheng, when did this tooth start to grow?" Qian Hao took back the stick and asked quietly.

"I'm afraid it's been a week." Grandma Zheng raised her upper body again. Obviously, she was not used to lying down and talking to Qian Hao above her head. "There's nothing else, it's just itchy."

Only one week? The growth rate of this tooth is too fast.

"So have you eaten something special a week ago? Or have you ever encountered anything special?"

"Oh, I've eaten it." Grandma Zheng's wrinkled face showed a little shyness. "I went to the health center to prescribe hemorrhoids last month, and the doctor there prescribed some medicines. It turns out that those medicines were causing trouble?"

"Do you still remember what medicine they all do?"

"Yeah, I don't remember this." Grandma Zheng said in embarrassment, "I just took it. Why don't I go back and take it to Dr. Money to take a look? I still keep those medicine boxes."

Although Qian Hao's profession is not Qian Hao's major, he knows a little bit. The medicines given after hemorrhoid surgery are nothing more than hemorrhoid drugs, as well as wound harvesting, anti-infection and other drugs. Moreover, no matter what medicine it is, it cannot make people grow such four teeth in a short period of time.

"Don't rush home to get it, anyway, I'm familiar with the doctors in the health center." Qian Hao noticed that Grandma Zheng's eyes seemed uncontrollable, and she slipped towards the round mirror on her forehead from time to time, making him feel indescribable awkward from the bottom of his heart. Try to keep a smile, Qian Hao stood up and said, "Lying down for a while, I'll call and ask."

Pearl Island is composed of six large and small coral reef islands, like a small tail, extending from the parent land to the sea in an irregular curve. The health center is located on Luming Island, the third island, several times in the direction of the mainland, and is separated from Hongyan Island where the dental defense office is located, the fourth island, Jiayu Island.

"Director Li? I'm Xiao Qian from the Dental Defense Institute." The person who answered the phone was the director of the Dental Department of the Health Center. In the health center, he was one of the doctors who contacted Qian Hao the most in business. "I found a strange case here. Can you arrange a bed there? I want the patient to transfer to the health center for a comprehensive examination."

“….”

Director Li is a funny doctor who talks a lot, so he is deeply supported by the patients. He is probably busy now. Seeing that he didn't answer, Qian Hao waited for a while and said, "Director Li, why don't I call you again in a while?"

"...Did you have four teeth?" Director Li asked in a daze.

"...Yes." Qian Hao felt strange, why did Director Li know about Grandma Zheng's situation?

"... It is symmetrical up and down, left and right, growing on the outside of the gum, with large upper teeth and small lower teeth?" Director Li's voice lowered a little, as if he was very tired.

"……yes."

"Have you come to our health center for treatment recently?" It sounded like Director Li was asking a question almost as if he was begging.

"……yes."

"…..." Director Li was silent for a long time before sighing, "Oh, you send the patient here first. Put on a mask and gloves, and try not to have more contact with the patient."

"...infection?" Qian Hao was shocked. When he was in contact with Grandma Zheng just now, he did not pay special attention to protection. If it was respiratory infection, he might have been infected. However, since he studied medicine, Qian Hao has never heard of any disease that infects teeth.

Director Li's voice lowered a little, and he replied vaguely: "I don't know."

??

What does it mean? Qian Hao asked urged: "Director Li?"

"Oh, if you stay in the dental defense center, you may encounter such cases sooner or later, so I'll tell you clearly." Director Li took a deep breath and said again, "We have admitted four such patients since last month. At first, we couldn't figure out the reason, and later we found that all the patients had surgery and had blood transfusions recently. We suspected that there was a problem with the blood bank. These patients were all blood type O. We thoroughly examined the blood storage in the blood bank and all the medical equipment and equipment that might be used during the blood transfusion process, and could not find any problems."

"You mean, it may not be a problem during the blood transfusion?"

"We don't know. We visited patients who had surgery at the same time and had other blood types and had no problems."

"Then the infection you just mentioned..."

"Because the reason cannot be determined, we cannot rule out any possible xing." Director Li paused, "For me personally, I suspect that some patients with type O blood have problems with their own blood, and when they are mixed into other people's blood, they will have abnormal changes."

"Has it been reported?"

"...Not yet. I asked from multiple sources, and it seems that there is no similar disease in other places except us. First, we are not sure whether it is really contagious; second, we have not found any other harm to patients except teething; third, we cannot confirm the cause of the disease... You know, once reported, our health center may..."

"I understand, I understand."

If only a few people are involved in the disease, they do not have contagiousness, and there is no specific harm, reporting is indeed a cause of trouble. On the contrary, Qian Hao is very interested in participating in the research on this new disease. If it is a research, it is of course better to keep it confidential before the results are achieved.

"...If new patients continue to appear, I'm afraid they won't be able to report them." Director Li said tiredly, "Little money, you send that patient by yourself. Let's take a look at my medical records here. I also want to hear your professional opinions."

"Okay, OK. I'll come here right away." Qian Hao couldn't ask for this invitation. Of course, as a doctor, he had to first ensure that he was not infected. "Director Li, do patients really have nothing in common except blood? Will there be other ways of transmission?"

"Not found yet. The reason for suspected blood..." Director Li pondered for a moment and changed the topic, "Didn't you think of anything after seeing those teeth?"

Qian Hao recalled the four teeth in Grandma Zheng’s mouth, which were sharp and protruded outside the gums. If only one of them grew, it would be a bit like...

“…Canis tooth?”

"Well, maybe your patient's teeth have not grown enough yet. You can imagine that when it grows twice as long as it is an ordinary tooth, it will not look like a canine tooth, or at least like a wolf tooth." Director Li's voice was a little trembling, "...and every time I see it, I think of... the legendary... vampire..."
