A dental bridge is a dental appliance that is composed of a crown (false tooth) and two abutment teeth to anchor the crown to the healthy teeth on each side. This appliance can last decades before its wear-and-tear, depending on how you maintain and clean them to prevent possible problems. That is why annual check ups are important to prevent dental problems such as tooth decay. But what if it gets loose and tooth decay seeped through? Do you know how to spot tooth decay under bridge symptoms?
