“…This can lead to behavioural changes including avoidance of certain foods, for example dry, spicy or crunchy food, and/or preference for soft and carbohydrate‐rich foodstuff. In turn, changes in food intake can result in nutritional deficiencies, weight loss, malabsorption and atrophy of the masticatory muscles and impaired masticatory performance (Crowder, Douglas, Yanina Pepino, Sarma, & Arthur, ; Dusek et al., ; Gilbert, Heft, & Duncan, ; Jensen et al., ; Loesche et al., ; Pedersen et al., ; Yoshikawa et al., ), leading to further aggravation of the oral health (Sheetal, Hiremath, Patil, Sajjansetty, & Kumar, ).
