This is a condition where only the gums are infected. It is REVERSIBLE with good home care. Does your son have any health issues? Does he smoke? Some vitamin deficiencies can contribute to bleeding gums. The hot smoke from cigarettes irritates the gum tissue. When your son visits the dentist you or your son can ask about the correct way to floss. Flossing is done along side the tooth, going down as far as you can go. You scrape this area gently. You hold the floss between the pointer fingers on each hand and scrape gently. You scrape up and down. You will be surprised at the white material that you scrape off. Brushing is next. You start on the last tooth in your mouth. With a soft toothbrush, you brush back and forth gently. The toothbrush is half on the tooth and half on the gum line. (Make sure you floss behind the last tooth and brush that gum line tooth area.) You brush all around to the opposite side on the lower, brush behind the last tooth on the lower and brush the gum line where your tongue rests. Go all around. Then brush the upper teeth, start in the back brush the tooth gum line area, back and forth. That 1/2 tooth1/2 gum line area, if not taken care of problems will start. Now you brush all the flat surfaces of all your teeth. Take a tongue cleaner or a teaspoon. Turn the round part to face the palate. Place the teaspoon in the middle of your tongue. Go back as far as you can without gagging. Gently scrape your tongue back to front. You will see a slimy mass of debris. That's what was in the nooks and crannies of your tongue. RINSE the spoon and do the other two sides. Rinse your mouth with salt water, then gargle. You can use a water irrigator. Your mouth will feel fresher. You can put some salt water in the water irrigator. It took me a long time to explain in writing. After you floss and clean your teeth, your mouth should feel fantastic. If you are flossing and brushing correctly you should not have bleeding gums. The toothbrush is soft. You are brushing gently. You are brushing back and forth at the tooth-gum line area. It should be like a message, not harsh. You are not raking your gums. Your toothbrush should be changed every 3 months. If you are using a sonic toothbrush, you place the toothbrush head. 1/2 tooth, 1/2 gum brushing back and forth.
