Impact of Mental Health on Oral

"The Mind-Mouth Nexus" exposes the inseparable bidirectional link between mental and oral health. Depression, anxiety and stress fuel neglect of oral hygiene, medication-induced dry mouth and harmful habits (smoking/sugar binges), accelerating cavities, gum disease and tooth loss. Conversely, oral pain, visible decay or tooth loss erodes self-esteem, triggers social isolation and worsens mental health through biological pathways: gum inflammation elevates brain inflammatory cytokines (IL-6/TNF-¿), impairing mood regulation.High-risk groups severe mental illness (3× tooth loss), elderly, substance users ("meth mouth") and marginalized communities suffer disproportionately due to stigma, poverty and fragmented care.Solutions demand integration:¿¿ Dentists screen for depression; psychiatrists prioritize oral referrals.¿¿ Trauma-informed dental care for PTSD/anxiety.¿¿ Policy: Medicaid dental expansion, sugar taxes, school fluoride programs.¿¿ Community Teledentistry and anti-stigma education.Breaking healthcare silos is urgent. Healing minds requires healing mouths and vice versa.
