How Long Does Teething Last in Newborns and Babies?

Babies may find new teeth erupting as early as 4 months old. Parents may tire of the teething process if their little ones are prone to fussing and swollen gums. Though the teething time frame can vary from baby to baby, parents can do plenty to ease the pain during such a big change in baby's life.

When Does Teething Begin In Infants?

Most babies will begin teething between 4 and 7 months, according to the American Academy of Pediatrics 1. Some babies may begin months after that period, and this is not necessarily a cause for concern. If a baby's parents began teething later than average, then baby also will likely teethe later than average. A fever below 101 degrees Fahrenheit and fussing are common symptoms of teething, as are sore and swollen gums. When teething begins, parents may first notice that babies are drooling more often than usual, according to KidsHealth 23.

How Long Does Teething Last?

Teething is an ongoing process, and once it begins, it will continue through the rest of your child's infancy. Most children finish teething during the toddler years, typically around the second birthday, according to the American Academy of Pediatrics 1. Toddlers should have all 20 of their teeth by their third birthdays, advises KidsHealth. If your child is still teething past his third birthday or if his development seems to be behind compared to other children, ask your pediatrician for advice 1.

Managing Teething Symptoms

Parents may wonder how long teething will last if their babies are struggling with teething symptoms. Chilling a rubber teething ring in the fridge for half an hour before giving it to baby can relieve gum soreness, says Boston Children's Hospital 1. Parents can also substitute a cold, clean cloth for a teething ring. Never give your baby any frozen items when teething. During teething, babies may also prefer to eat chilled foods rather than hot or room temperature foods.

Additional Help

Some parents may endure frequent sleep disruptions because of teething. If your infant seems to be struggling, contact her pediatrician for an evaluation, especially if your baby has a fever higher than 101 degrees or if she is vomiting or having diarrhea. These are not typical symptoms of teething and may be a sign of another illness, according to KidsHealth 23. Ask your baby's pediatrician if you can give her children's acetaminophen or ibuprofen to relieve the pain. Never give your child aspirin, as aspirin is unsafe for children, because it may cause Reye's syndrome, a rare but serious illness that has been associated with use of salicylates during a viral illness.
