Does doing a dental filling, root canal and crown dental surgery affect my Ramadan fast?

They might need to inject my gums or cheek to anesthetize the area.

It is better to do this procedure at night to avoid doubts. However, if one has no choice they can go and do it during the day and avoid swallowing anything like blood. If this is done, then the fasting will not be affected. However, if during the procedure you voluntarily swallow something then the fast is broken.

And Allah knows best.
