Why does my 18-month-old baby grind their teeth? Everyone around me is saying different things.

Teeth grinding (bruxism) is quite common in 18-month-old babies and is usually temporary. The most common cause is the unfamiliar sensation new teeth create in the mouth—your baby may be "trying out" these new surfaces and the pressure they exert. Also, the development of tongue and jaw muscles during this period can lead to involuntary movements.
Stress or excitement can also be a trigger: intense play during the day, a new environment, or too much stimulation before sleep can increase nighttime grinding. Concern about parasites (worms) is commonly heard, but there is no scientific evidence linking parasites to teeth grinding.
In most babies, grinding doesn't cause permanent damage to teeth and usually resolves on its own within a few months. If grinding is accompanied by jaw pain, facial swelling, or visible wear on teeth when your baby wakes, I'd recommend consulting a pediatrician or pediatric dentist.
I understand that when everyone says different things, your head spins—but at 18 months, this is mostly just a harmless developmental phase.
