She Could Hear Him Grinding From the Next Room

Quick answer: Grinding is common in young children, usually causes no lasting damage, and in most cases stops on its own by the time the adult teeth arrive. Night guards are rarely appropriate at this age. What is worth ruling out is a breathing problem during sleep.

The call

The sound was the complaint. Loud enough through a wall to wake her, several nights a week, for about a year.

A mother in Ramat Shilo brought her six-year-old, Dovid. She had been told by two people that grinding means worms — a belief that circulates widely and has no basis — and by a third that he needed a night guard.

Neither was right, and the useful part of the appointment was a different question altogether.

What we found

Wear facets on the baby canines and molars: flat, shiny areas that matched precisely against the opposing teeth. No fractures, no exposed dentine, no sensitivity.

He had no jaw pain, no morning headaches, and no difficulty eating.

Why grinding is so common in children. A substantial proportion of children grind at some point, most commonly between about three and six. The likely reasons are developmental — the bite is changing constantly as baby teeth wear, loosen and are replaced, and grinding appears to be part of how a child's jaw finds its position. It typically decreases as the permanent teeth come through and often stops entirely.

Why night guards are rarely used at this age. A child's jaw is growing, and an appliance worn nightly through active growth can interfere with normal development of the arches. The teeth being worn are mostly baby teeth, due to be shed anyway. Very few six-year-olds tolerate a guard through the night in any case.

The exception worth taking seriously. There is a well-documented association between grinding in children and sleep-disordered breathing — snoring, mouth breathing, enlarged tonsils and adenoids, and obstructive sleep apnoea. One theory is that grinding is part of the arousal response that re-opens a partly obstructed airway.

So the questions that mattered were not about his teeth:

• Does he snore? Most nights, loudly.
• Does he sleep with his mouth open? Always.
• Does he stop breathing or gasp? She had noticed pauses.
• Is he restless, or does he sleep in odd positions? Constantly, and often with his neck extended.
• Is he tired or irritable in the day? Yes, and his teacher had raised concentration.

That is a positive screen, and it changes the appointment entirely. We also examined his tonsils, which were visibly enlarged, and noted a high narrow palate and mild anterior open bite — the facial pattern associated with chronic mouth breathing.

What we did

Referred him to his kupah doctor for an ENT opinion, with a written summary of the dental findings and the sleep history. That letter was the substantive output of the visit.

He was seen by ENT, had a sleep assessment, and had his tonsils and adenoids removed four months later.

Nothing dental. No night guard, no treatment of the wear, no restorations. Monitoring with photographs at six-monthly reviews.

Reassurance about the myth, explicitly. Grinding does not indicate intestinal worms. That belief persists strongly enough that it is worth addressing directly rather than politely ignoring.

The outcome

The grinding stopped within about six weeks of the surgery. Not reduced — stopped. His mother's report was that the house was quiet and that he was a different child in the mornings.

The wear on his baby teeth has not progressed. The mild open bite improved over the following two years as the mouth breathing resolved, which is a recognised pattern.

His permanent teeth erupted normally and he does not grind.

Not every case has an airway explanation, and most childhood grinding is benign and self-limiting. This one had a cause worth finding.

What to do if this happens to you

1. Do not panic about the noise. Most childhood grinding is benign and self-limiting.
2. Ask about breathing during sleep — snoring, mouth breathing, pauses, restlessness.
3. Mention daytime tiredness or concentration problems. They are part of the same picture.
4. Do not accept the worms explanation. There is no basis for it.
5. Be cautious about night guards for young children. Growth and tolerance both argue against them.
6. Ask for photographs at reviews so wear can be tracked objectively.
