A mother-of-two in agony from toothache died after she fell into a coma just hours after having a tooth extracted.

The 27-year-old patient, named only as Alina Z., had put off seeing the dentist for months, according to local media in Novosibirsk, Siberia, southern Russia.

When she could not bear the pain any longer, Alina booked an appointment on 30th November, and the tooth was pulled out.

But as she walked home, Alina felt dizzy and vomited before passing out, according to reports.

When she finally got home, her family said that she was barely conscious and coughing up blood.

Alina was rushed to hospital and fell into a coma caused, doctors believe, by a severe infection.

She was declared dead from organ failure two days later, on 2nd December.

Alina’s sister, who has not been named, told local media how she could barely stand when she got back from the dentist.

She said: “She somehow got home, she was dizzy.

“After arriving home, she began acting strangely about 15 minutes later. She spat blood, didn’t speak, didn’t react.”

Alina’s sister said her horrified children were watching their mother’s agony.

She said: “Two little children were all looking at this; they saw how their mother was dying.”

Now Alina’s family are calling for an inquiry into her treatment and believe that she may have acquired the infection during the visit to the dentist’s.
