Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
No, tooth extraction does not cause vision problems or loss or blurring of vision.
So do not worry about it.
The symptoms that you are facing can be due to sinus
related problem that can be secondary to tooth extraction.
However if it is sinus related then it can be very well treated.
So my suggestion is to consult an oral physician and get evaluated.
An x ray
can be done for confirmation.
For now put decongestant nasal drops like Otrivin
and do steam inhalations.
Avoid vigorous snuffing of nose.
Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Honey Arora
