Is my baby teething?

A baby’s first tooth usually appears between 8 and 12 months of age. Many symptoms, such as gum irritation, irritability, loose stools, and drooling, have been associated with teething, but none are particularly reliable. Some babies have no symptoms and others are a little bothered for a few days. Families who feel they need to relieve their baby’s discomfort can let the baby chew on cold teething rings or wet face cloths, or rub the baby’s gums with a clean finger. Medication can be dangerous and are not recommended. Teething necklaces may contain bacteria and also pose a strangulation risk. Teething does not cause high fever, vomiting, diarrhea, major irritability, or a sudden change in breastfeeding patterns.

A) The history of teething

Two thousand years ago, the Greek doctor Hippocrates claimed that teething caused crossed eyes, fever, seizures, and death. This belief continued until the late 19th century. Up to half of all baby deaths from the 16th to the 19th centuries in France were wrongly blamed on teething (Markman 2009).

Treatments for teething likely contributed to the deaths of many babies and included (Dally 1996; Markman 2009):

  • Feeding rabbit brains to the baby.
  • Giving medication to cause vomiting or diarrhea.
  • Giving cocaine, opiates, lead, mercury, honey, or salt.
  • Cutting or blistering the gums.
  • Placing leeches on the gums.

These treatments would have caused dehydration, poisoning, or infection.

Concerns over teething remain today.

B) Signs of teething

Some babies have no symptoms of teething and others are a little bothered for a few days. Many symptoms have been associated with teething, but none are particularly reliable. Teething symptoms can include:

On average, a baby’s first tooth erupts at 8 to 12 months of age. Teething problems are unlikely before this time. A very small number of babies are born with one or more teeth (natal teeth). All of the baby's first teeth are present by 33 months (Li 2017; Markman 2009). 

Erupting teeth are easily felt with your finger; they are very hard and appear on the ridge of the front gums.

C) Treatment of teething

1) Appropriate treatment

If you feel you need to relieve your baby’s discomfort, consider using direct treatments such as:

  • Allowing the baby to chew and suck on:
    • Cold teething rings.
    • Cold, wet facecloths.
  • Rubbing your baby’s gums with your clean finger.

2) Treatment that can pose a risk to the baby

Medications for teething are not recommended, as they can be dangerous.

Some parents use teething necklaces. Amber necklaces, in particular, have been popular, but these may contain bacteria that can infect the baby (Machet 2016). They pose a strangulation risk, and testing has shown they may not release if a baby becomes caught (Cox et al. 2017; Soudek and McLaughlin 2018). They may also injure the baby’s mouth or teeth.

D) Misdiagnosing teething

Babies often have tiny white bumps on their gums and on the roof of the mouth that some parents mistake for teeth. They are normal, do not cause pain, and should be left alone. 

While some babies may drool more when teething, many babies start to drool from the age of one month, well before the age of teething.

The second six months of life brings many changes for babies. They may feel frustrated when they are close to attaining new milestones or anxious when separated from their caregivers. They may be in more contact with others, increasing the risk of infection and illness. All of these may cause unhappiness and none are related to teething. 

The diagnosis of teething can lead to a sick baby not receiving care. Teething does not generally cause:

  • Fever (temperature of more than 38°C or 100.4°F) (Memarpour 2015)
  • Vomiting
  • Diarrhea
  • Major persistent irritability
  • A sudden change in breastfeeding patterns

Babies with these signs should be seen by their health-care providers
