Not following what to do after tooth extraction can have consequences. As advised by this Pymble dentist for your safety, it is best to put gauze on your tooth extraction site and replace it often. Infections in the gums may indicate that your previous tooth extraction didn’t close. Hence, food debris or bacteria gets stuck on the hole that didn’t seal properly. If you see more dental concerns similar to bad breath after tooth extraction, it is best to visit your nearest dental clinic.
