Signs of Teething
Recent research has shown that teething won't make your baby truly sick, though it may make them distressed and irritable for a time. According to the American Academy of Pediatrics (AAP) in the United States, 10 comprehensive studies show that signs of illness, such as fever, are not indicative of teething. Instead, true fever (classified as a temperature of 38 Celsius or higher) is a sign of another illness and should be treated as such.
Nonetheless, a gradient rise in temperature can be attributed to teething. The AAP also notes the most common signs of teething are irritability, gum tenderness and drooling. If you notice your baby chewing on their hands or toys alongside all or one of these signs, it's most likely teething.
Of course, no matter your age, dealing with tooth pain can cause agitation and result in fatigue due to poor sleep. For parents who are hoping the process isn't overly daunting each time — for your baby or for your sleep schedule — the AAP notes that peak teething irritation occurs when your baby cuts their front teeth (or primary incisors). That typically happens between 6 to 16 months.
You may also notice that some teeth take longer to cut, such as molars, which have broader and more blunt surface areas. Your child may have redness in their gums and may favor softer foods or be averse to eating during particularly tender teething phases.
