Answer

A study by Chang et al suggested that BPPV can be triggered by dental procedures. The study, which included 768 patients with BPPV and 1536 controls, found that within 1 month before they were diagnosed, 9.2% of the patients with BPPV had undergone dental treatment, compared with 5.5% of controls within a month before they were identified. Adjustments for demographic factors and comorbidities indicated that a positive relationship exists between recent dental procedures and BPPV. [4]
