Dear Lybrate user, the doctors usually ask for artificial teeth
while admitting patients in the hospital with regards to removable partial or complete dentures
. Any patient who requires oxygen mask or tubings through the mouth or neck area for breathing or nutrition or a patient who is unconscious has to get the denture plates removed because it involves the risk of aspiration/accidental swallowing
. The link between poor oral hygiene and heart disease is limited to the fact that a person with poor oral health and bacteria in his mouth stands a risk of transfer of these bacteria to the heart via the blood stream. Otherwise, dentures, crowns/caps, bridges, fillings
etc do not have any role in causing heart problems.
