<s>[INST] My grand mother is now 68 years. her teeth has fallen. She now has difficulty in eating anything. She usually swallows the food and she has difficulty in taking foods like chappathis. We went to a dentist and the doctor advised her for getting dentures. What are theses dentures? [/INST] Dentures are a set of artificial teeth (upper and lower), which are removable i.e.: can and should be removed at night or during cleaning. They resemble gums and teeth and are made of acrylic material. Denture fabrication will take around 5-6 visits to the dentist. Wearing dentures will not only help your grandmother to chew properly but also improve her appearance which will make her feel good. Regards </s>
