Cavities are not always about laziness: depression, ADHD and your teeth
Do You Know? For patients.
When someone struggles to keep up with brushing, the cause is often not carelessness. Mental health conditions affect energy, routine and even saliva.
What studies show
In adults, depression is associated with a higher chance of tooth decay, and tooth loss is associated with a higher chance of depression, suggesting a two-way cycle.
Children with ADHD have higher rates of decay than their peers.
Some medicines used for depression and ADHD reduce saliva, which leaves teeth less protected.
Small steps for low-energy days
Brushing for a short time is far better than not brushing at all.
Keep a toothbrush and fluoride toothpaste somewhere easy to reach.
Sip water often and choose sugar-free gum if your mouth feels dry.
Tell your dentist. A prevention plan can be adjusted, for example with stronger fluoride, without judgement.
