Dental crowns need normal daily cleaning
A crown should be brushed like a natural tooth, especially around the gumline, where plaque can collect. Even though the crown material itself cannot decay, the tooth underneath can still be affected by decay or gum problems. Regular cleaning between the teeth with floss or a similar cleaning aid, plus regular brushing, is key.
Bridges need extra cleaning underneath
A bridge is joined together, so floss usually cannot pass straight down between the connected teeth. Special floss, interdental brushes, or a water flosser may be needed to clean underneath the bridge and around the supporting teeth. A water-spraying cleaning aid like a Waterpik/Waterfloss in conjunction with regular flossing is a great choice.
Good hygiene protects the investment
Keeping the area clean helps reduce the risk of decay, gum inflammation, bad taste, bleeding gums, and significantly helps the long-term lifespan of the bridge or crown.
