I have 5 residual root tooths that should have been pulled years ago, but i was unable to get dental treatment,i'm 5 weeks pregnant and before pregnancy a dentist told me i should pull the 5 roots cause are causing infection, can this harm my baby?

Infections from retained roots can spread, and therefore stress your immune system. You should have the roots removed. Have your dentist consult with your OBGYN.

Yes. See a specialist Oral Surgeon. Once sources of infection are removed, have your Dentist check you carefully to make sure that your teeth/gums Arte healthy. Oral infections have been associated with premature births and low birth weight.
