Generally, wearing a removable denture does not cause pain. However, sometimes there are sharp bone protrusions or bone tips in the missing tooth area or ulcers in the patient’s mucosa, which may cause pain when wearing the denture. If the patient is missing teeth for a long time, or if the patient has a large tongue or buccal mucosa, the patient may bite into the cheek or tongue after wearing the denture, which may also cause pain. If the retainer is made too tight, it may affect the abutment teeth and cause slight pain when wearing it. If the denture is not made properly, or if the abutment is too long, or if there are sharp protrusions on the surface of the abutment, this may also cause pain when wearing the tooth. In these cases, it is necessary to adjust and sharpen the denture, so it is important that the patient try it on himself. In addition, the incorrect way of wearing the denture may also cause pain to the teeth or mucous membrane, so it is important to follow the instructions of the doctor when removing the denture. If you can’t remove or put on the denture with great force, you must stop removing it.
