Why some people die cause by tooth removal?

Bleeding, infection: Hi. Fortunately, death from tooth extraction is vanishingly rare. But tooth extraction can rarely result in sepsis and heart valve infection, which can kill, and in people with bleeding problems, the bleeding can kill. Both these complications are less likely than being struck by lightening (my personal risk estimate!). Good luck!

Unlikely: I thought about your question and can only think of one answer: 1. Tooth removed....infection occurs....aspiration....pneumonia develops.....patient is immune-compromised (with Diabetes or Elderly). Patient doesn't see their doctor.....starts coughing and gets "septic".....infection spreads throughout and by the time the patient decides to see the doctor, it could be too late.

Extractions: It's not the extraction that causes death, it's the complications from dealing with infection. The obvious answer is see your Dentist regularly to prevent infection, to prevent need for extractions.

RARE and why?: The estimate of deaths related to dental treatment from studies over the past 60 years is 1 in 400,000. More likely to have complications with people who are medically compromised, have unknown medical conditions, & more years ago than recently from doctors who did not have adequate training in medical emergencies. Nowadays, with training of Oral Surgeons & certification, very very rare!
