This eruption of primary teeth, or teething, can cause sore and tender gums that appear red and puffy. To relieve the soreness, give the baby a cold teething ring or washcloth to chew on. Teething medicine is not recommended. Many primary teeth will not be replaced by permanent teeth for 10 to 12 years. Until that time, they need to be kept healthy to enable a child to chew food, speak, and have an attractive smile.
Primary teeth are at risk for decay soon after they erupt.
Over time, these bacteria dissolve the enamel, or outer layer, of the tooth. This damaged area is called a cavity. Regular brushing prevents the build-up of bacteria and sugars and the damage they cause. Baby bottle tooth decay occurs when a child's teeth are exposed to sugary liquids, such as formula, fruit juices, and other sweetened liquids for a continuous, extended period of time. The practice of putting a baby to bed with a bottle, which the baby can suck on for hours, is the major cause of this dental condition.
