Hello,
A tooth crown can come out due to a lot of reasons. It is nothing to be afraid of. Depending on the present condition of the tooth, it may either be fixed again or treated (if the tooth does not appear to be normal) and then re-cemented. Unless it is not causing harm or pain, you can afford to wait for a while. But before that, you must self examine the condition of the tooth.
Next Steps
-Take a view in the mirror, check the appearance of the tooth.
-Ask someone to click a picture and then show it to a dentist to evaluate its condition.
-If it doesn’t look like an emergency, wait till the situation becomes better (pandemic)
-If there is pain/discomfort go to a dentist, take an appointment and inform him/her about your pregnancy.
Health Tips
It will be alright!
