As the saying goes, “You don’t fight an unprepared battle.” Everything is prepared in advance. Dental care is no exception, generally need to do the following points of preparation. 1, to eat a good breakfast before seeing a doctor, except for special laboratory tests, need to fasting blood draw, generally should eat a good breakfast to go. Some people do not eat breakfast after waking up because of toothache, and then rush to the hospital by squeezing the public bus. Just sitting on the dental chair, see the dentist pick up the dental instruments, it produces nervousness, as a result, some patients appear head sweating, cold fingers, and even have the hypoglycemic symptoms of delirium. This is mainly a hunger, two tired, three scared caused by. 2, brush your teeth before going to the dentist, do not go to the dentist after eating, with a mouth full of food residue. This has two disadvantages: (1) when the dentist examines the teeth, first to spend time to remove the food debris accumulated on the teeth, in order to see the situation of the teeth; (2) generally speaking, the dentist to see a cleaner mouth, the heart is always more comfortable, but also convenient to do some examination and treatment. Especially to remind those who love to eat raw garlic, etc., with a special smell of food, before seeing the dentist, must not eat such food, so as not to cause unpleasant to the dentist. 3, dressed appropriately to see the dentist, we do not require as some important occasions, wearing expensive clothing, but also can not be too casual, wearing a sweatshirt undershirt. Rather, the general requirement is to dress appropriately, neat and generous. Although a breast scarf will be put around during the treatment, it is always unpleasant in your heart in case you accidentally dirty your expensive clothing when rinsing, rinsing, or spitting. It is worth noting that some ladies should not wear heavy makeup. 4, prepare a good medical history and condition information, see the dental doctor always have to ask your medical history and condition, combined with a variety of tests, in order to make a correct diagnosis and give appropriate treatment. The medical history is how long you have had the disease; the condition is what symptoms you have, or uncomfortable situation. Now take toothache as an example, you should generally state the following questions: which part of the body hurts? Is the pain spontaneous or irritating? Is it a continuous pain or paroxysmal pain? Is it a mild vague pain or a severe pain? How long has the toothache been present? When describing the medical history, it is required to answer the questions concisely and accurately without exaggerating or narrowing down, in accordance with the doctor’s instructions. 5.
