Dentures are a common organ substitute in our lives. Proper use will bring convenience to our life, and improper use will cause damage. Fixed dentures either single, or several are small and easy to get used to, but the fixed bridge part is easy to accumulate food residue, brush teeth to clean especially. If the dentures are too high, loose, biting pain, etc. should be checked by a doctor as soon as possible. The movable dentures can be taken off and put on at any time, so practice the method of taking them on and off first. Whether putting on or taking off, do not use excessive force. Do not use the bite force to make it in place when wearing, so as not to break or deform the denture attachment, and pull out lightly against the direction of wearing. If you feel pain and discomfort after wearing dentures, you should find a doctor in time, do not wear them, and do not repair them yourself. Even if it is uncomfortable, you should wear it for 2-3 hours before going to the doctor, so that the uncomfortable part will leave traces on the dental bed for the doctor’s reference. After the habit of wearing teeth, the dentures should be taken off and soaked in water at night before going to bed. The denture scrubbing brush should be used with soft bristle brush, the denture should not be worn again for a long time, most of the denture has been deformed at this time, such as wear may cause damage to neighboring teeth or opposite teeth. Full dentures are large in size and generally take about 1 month to adapt after fitting. Dentures generally can not bite too hard things to avoid fracture, wear movable dentures also can not bite viscous food to avoid dislocation bite bad. Around the denture is easy to retain food residue, after each meal should be cleaned. The force of chewing food should be slowly increased in order to gradually adapt.
