In our daily work, we often encounter these small misunderstandings about orthodontic treatment that most patients may have, which are roughly summarized as follows: Myth 1: Orthodontic treatment is only for the sake of beautiful teeth, which is a more common view. Some adults (especially men) who come to the clinic often feel embarrassed, or even unable to make up their minds about treatment because they are afraid of being laughed at by their colleagues or friends. This is understandable but not desirable. Orthodontic treatment in addition to beautify the smile, its role there are many, such as: 1, conducive to the maintenance of periodontal health, irregular teeth naturally difficult to clean, prone to tartar deposits, gum redness and swelling and hyperplasia (there will be bleeding from brushing, halitosis, etc.), periodontal lesions may occur over time (loose teeth, receding gums, etc.), it is even more difficult to treat! 2, conducive to the prevention of dental caries, the same principle, the gap between the teeth due to misalignment of teeth and difficult to completely remove plaque, long-term can lead to the occurrence of dental caries. 3, can create favorable conditions for dental restoration treatment. 4, is conducive to enhancing personal self-confidence. It is also a very important point. According to my observation, in life or on TV as long as you see someone in the hand blocking the mouth smile, do not think they are shy or what, in all likelihood, have dental problems! Whether it is at work or in the relationship with friends, can have no fear of a bright smile, can be greatly added to your personal charm, at the same time I think that have a neat and beautiful teeth is also a reflection of the quality of life of individuals, so let the teeth of the unsightly people is definitely not as good as with orthodontic appliances of the people with a more positive attitude to life, the mental health of the more! As a netizen said, two years in the whole life is not long, but it can bring you a lifetime of beauty, so what reason do we have to refuse the invitation from the goddess of beauty Myth 2: The faster the teeth move, the better. Often anxious patients will ask: “Doctor, can not be faster?”, “I can not come back to see the doctor? “Can I have shorter intervals between follow-up appointments?” Some may even say, “Doctor, put more force on it, I’m not afraid of pain!” However, tooth movement has its own biological laws. Within a certain range of force, the teeth move the fastest and have fewer side effects. If you don’t reach the minimum force value, the teeth will not move naturally. But if the force is too large, the teeth not only will not speed up, but will play the opposite role, but also occurs in the alveolar bone of the subtle resorption, periodontal tissues can not be repaired, resulting in loose teeth, pain, and even root resorption, pulp necrosis. As the saying goes, you can’t achieve what you want to achieve. It can be seen that in the orthodontic process, only according to the biological laws, the scientific use of power in order to achieve both fast and good purpose.
