Dental Problems

Oral conditions may affect chemosensation either directly, by altering the underlying biology of the taste system, or indirectly by introducing exogenous stimuli that produce abnormal taste and smell sensations. Among the most commonly cited oral conditions associated with taste alterations are periodontal disease, salivary flow changes, prosthodontic appliances, "galvanism", and oral mucosal lesions. However, most reports are anecdotal.
