Maintaining good dental hygiene can be challenging for many families, but for parents of children with autism spectrum disorder (ASD), toothbrushing may become a daily source of stress. Experts emphasise that understanding the reason behind a child’s resistance is the first step towards building a successful routine.

Why toothbrushing feels overwhelming

Children with ASD may experience sensory sensitivities that make brushing uncomfortable. The texture of bristles, the taste or foaming effect of toothpaste, motor skill differences, or communication challenges can all contribute to difficulty.

According to specialists at the Huntsman Mental Health Institute, what may appear as refusal is often an inability linked to sensory or developmental factors. Identifying whether the challenge is sensory, motor-, or behavioural helps parents tailor the approach.

Practical strategies for parents

Experts from the University of Utah School of Dentistry recommend selecting a soft-bristled toothbrush suited to the child’s mouth size and starting with a manual brush before considering an electric one. Choosing a toothpaste flavour the child prefers can also make a significant difference.

Establishing a predictable routine — brushing at the same time and place daily — provides structure, which many children with ASD find reassuring. Visual schedules and timers can help children understand expectations.

Parents are encouraged to model brushing by demonstrating each step slowly. Offering praise after each small success can build confidence. If needed, caregivers may assist physically by standing behind the child and guiding gentle brushing motions.

Importantly, professionals advise against abandoning brushing entirely. Even using a wet toothbrush without toothpaste is preferable to skipping oral care.

Seeking professional support

If home care remains stressful, families can seek specialised assistance. Programmes supporting children with developmental disabilities provide structured guidance and tailored dental services, helping reduce anxiety around clinic visits.

With patience, understanding and expert input, dental care can gradually become a manageable — and even empowering — part of a child’s daily routine.
