My brother is disabled. He can't take care of himself and brush his teeth. He used to brush his teeth, but he vomited and didn't know how to spit out foam and water.

First take my brother to the periodontal department for periodontal cleaning, and then insist on it once every six months. Then I usually brush my teeth with an electric toothbrush. If my brother can't spit out foam, I'll buy some "chlorhexidine" to brush my teeth. Chlorhexidine is the main component of mouthwash at ordinary times, which should be effectively solved. If not, buy a drainage device or an aspirator. After painting here, hang it in the corner and rinse it with water.

I wish you recovery and hope to help you. Good people are safe all their lives.
