Is it possible for major dental work (i.e. braces) to cause sinusitis?

Call the doctor right away and get antibiotics. However there is no way to prove that the dental work was the monster. She may have contacted the virus before the dental work and it just happened the symptoms appeared after the dental work.Viruses and bacteria all have differ ant incubation periods and this leads to differ ant symptoms and when they actually appear as infection or in her case a respiratory illness. Sorry another mommy problem. Children do get sick.. Remind her to always wash her hands to avoid as many of those germs as possible. If need be remind the Dentist too.
