Did You Know...
Teething infants get some relief from chewing on hard objects (such as teething biscuits) or cold objects (such as firm rubber or gel-containing teething rings). Massaging the child's gums with or without ice also may help. If a child is extremely uncomfortable, weight-based doses of acetaminophen or ibuprofen are usually helpful.
Teething devices worn around the child's neck, such as teething necklaces or beads, should be avoided because they increase the risk of choking and strangulation.
Teething gels are not recommended because they are not any more effective than other measures of pain relief, and some contain a potentially dangerous substance called benzocaine. Benzocaine can rarely cause a serious condition called methemoglobinemia, which affects the ability of the blood to carry oxygen.
