You can’t take risk visit your dental surgeon soon. In pregnancy medicines should be avoided and any infection becomes complicated.

A proper oral hygiene is a prerequisite for a safe pregnancy. Even if there is no pain, any infection is not good in pregnancy. So, it is better to address the problem by visiting a dentist, and have the most conservative treatment done. Even in this pandemic, there are plenty of dental clinics operating with adequate protection and safety.

Hi there, I understand u r scared to visit a dentist and you are avoiding it now. There is an infected tooth which is not causing pain now bt it may get aggravated at a later stage. 22nd week is the second trimester and it's safe to go for a treatment . There are a lot of doctors who are following all covid protocols for emergency treatments. You can consult someone online who is available near by  and take a decision for your treatment. In my opinion you shouldn't leave it untreated for long.

Hello Greetings, based on your findings it is assumed that you have a sinus tract , you need to get it treated as soon as possible
