Many patients I saw in my daily clinical work came to the clinic only when they had unbearable pain symptoms: toothache caused sleepless nights, toothache caused facial swelling, could not open the mouth, and affected eating, this kind of passive medical treatment disrupted personal work life order, endured pain, increased the cost of treatment, and was a helpless move. Oral disease is developed from light to heavy, for example, in the early stage of caries, there is shallow hole on the tooth surface, the nerve of the tooth is not stimulated, and it is not painful, and it is not painful to come to the treatment in time when the hole is found, and the treatment can be finished in one time, and the function of the tooth is not affected, and the cost is only a hundred dollars. Once the caries develops to deep caries, from irritating pain when eating to continuous pain, until the pain affects the sleep at night, it is urgent to come to the clinic, at this time, the deep caries develops to pulpitis, it needs to deal with the pulp nerve, after root canal treatment, the function of the tooth is affected, it needs porcelain tooth to protect the crown and prevent the tooth from splitting, the whole process needs several times to visit the clinic, as fast as 6 weeks, the cost is more than one thousand dollars. It is more than 10 times the cost of early treatment. The eruption of wisdom teeth around the age of 20, due to the lack of development of the jaw bone, the mandibular 8th tooth (wisdom teeth) eruption position is not enough, the eruption of wisdom teeth is blocked, resulting in the wisdom tooth site prone to pericoronitis, if not treated in a timely manner, the local inflammation spread, causing facial gap infection, mouth opening is limited, affecting eating, and even infection penetrate the cheek muscles, skin, the formation of skin fistula, leaving scarring, affecting facial appearance. If discomfort is found in the last part of the mouth, and the doctor examines and takes dental films to confirm that the wisdom teeth are not in the right place, the doctor will arrange to remove the wisdom teeth after the inflammation of the wisdom teeth has subsided to prevent further pain and other complications from occurring. There are many other examples too numerous to mention. Therefore, when available, it is worthwhile to take the initiative to seek medical care, arrange for annual oral examinations for yourself and your relatives, treat any problems promptly, and ask your doctor, “What problems do I need to pay attention to?” Then you will achieve a high level of quality in health care prevention, comfortable medical treatment, less pain, and cost savings. This is what a doctor with a conscience has in mind.
