You can buy a water pik and clean under the bridge or buy a floss treader.
Flossing your teeth should be done first. I like finger flossing. You wrap the floss around your fingers. You slide the floss along each side of your tooth. You don't jam the floss on the pointed gum tissue. You go down as far as you can on each side of the tooth. You need to invest in floss threaders. Some threaders are like fishing line that has a loop. They look like
needle threaders only in plastic fish line. You place the floss inside the loop and pull the floss under your bridge to the inside of your mouth. You must clean under your bridge. You put the floss down against each side of the tooth. You will be surprised how much food gets under a bridge. If you don't clean under the bridge, your gum tissue can get infected. It can hurt. It will have an odor. The teeth, even though you have crowns, can decay at the gum line. Brush your teeth at a 45 degree angle. Brush on the cheek side and the tongue side. You have bone there. Get a tongue cleaner for your tongue. Rinse you mouth with your mouth wash or a 1/2 teaspoon of salt in an 8 oz. glass of water. I like mouth irrigators. They flush out tiny food particles. Remember, you want your teeth and bridge to last. Take care of those teeth you want to keep!
