I am 65 years old male. My teeth has become very sensitive and I am unable to consume hard/solid foods as it causes lot of pain and inconvenience while chewing the food. When I consulted Dentists, they told that lot of tear and wear has happened to teeth and to avoid all hard type of foods. Is there any treatment where I can restore the previous healthy state of my teeth and reduce the sensitiveness of my teeth. Request for your advise please.
