Are Down syndrome children more vulnerable to tooth wear?
Down syndrome doubles tooth wear risk—screen for reflux, mouth breathing, and acidic diet at every visit.
01Research in Context
What this study did
The team looked at tooth wear in children with Down syndrome.
They compared the kids to a control group without the diagnosis.
The study tracked diet, reflux, asthma, and mouth-breathing habits.
What they found
Children with Down syndrome had twice as much tooth wear.
Reflux, mouth breathing, acidic drinks, and asthma drove the damage.
The pattern showed up early and worsened quickly.
How this fits with other research
Dudley et al. (2019) systematic review saw the same trend in adults.
Their data say preventable dental disease stays high across the lifespan.
D'Souza et al. (2020) link mouth-breathing to sleep issues in babies.
Together the papers flag mouth-breathing as a red flag from infancy onward.
Why it matters
You can guard teeth if you catch the risks early. Ask about reflux at breakfast, watch for open-mouth posture during play, and swap juice for water. A quick dental checklist at every medical visit can spare pain, cost, and future behavior problems in the chair.

03Original abstract
BACKGROUND: An oral condition that has largely been ignored in the Down syndrome population is pathological tooth wear. This study is aimed to create more awareness of the reasons underlying the tooth wear observed in patients with Down syndrome and to suggest different methods to prevent this condition. This research also potentially serves as a platform for future researchers to perform an in-depth analysis of the factors we identified. The aim of this study was to determine if children with Down syndrome are more prone to tooth wear than children who do not have Down syndrome. METHODS: Our sample consisted of 120 children with Down syndrome who were compared with 120 children with no disabilities. The parents or guardians were asked to complete a questionnaire and a 3-day diet chart, while the wear on each tooth was recorded using the standardised Simplified Smith and Knight Tooth Wear Index. RESULTS: Children with Down syndrome experience tooth wear more frequently than non-Down syndrome children. A history of asthma, mouth breathing and gastro-oesophageal reflux disease as well as the intake of acidic diet and drinks has exerted significant effects on the prevalence of tooth wear. CONCLUSIONS: The early diagnosis and analysis of the underlying aetiology are important for the management of tooth wear in children with Down syndrome who have shown a greater tendency to develop erosive lesions.
