Correctly interpreting the use of steel mouthguards is a common oral care tool that effectively protects teeth, gums and oral mucosa from damage. However, to be fully effective, steel mouth guards must be used correctly.
First of all, choose a mouthguard that fits the size of your mouth. A mouthguard that is too small will compress the gums, and a mouthguard that is too large will not fit snugly and protect the teeth. Therefore, when buying a mouth guard, you should choose the right model according to the size of your mouth. Secondly, you should clean your teeth before using a mouth guard. Food debris and plaque on your teeth can affect the effectiveness of mouthguards and may even lead to oral problems such as gingivitis. Therefore, you should clean your teeth thoroughly with a toothbrush before using a mouth guard. 
When installing the mouth guard, the mouth guard should be placed on the back teeth and slowly pushed down along the gums. At the same time, press the sides of the mouthguard with your fingers so that they fit snugly against your teeth. If the mouthguard does not fit snugly on the tooth, it should be adjusted or replaced. When using mouth guards, the following points should be noted:
1.The time of each use should not be too long, it is generally recommended to use it for 1-2 hours each time. 2.Do not replace a toothbrush with a mouthguard, only as an aid to teeth cleaning. 3.If you experience bleeding gums, pain and other uncomfortable symptoms during use, you should stop using it immediately and seek medical attention. In conclusion, the correct use of steel mouthguards can effectively protect the teeth, gums and oral mucosa from damage. During use, it is necessary to pay attention to issues such as choosing the right model, cleaning teeth, correct installation and use time. If any discomfort occurs, you should discontinue use immediately and consult a doctor.
