Thank you for your enquiry.
In general, if one wisdom tooth has been removed, we do advise removal of the opposing wisdom tooth as it then becomes non-functional and does not serve a useful purpose. When teeth are not biting on one another, they will keep growing and erupting more. This may eventually cause problems, if it overgrows too much. Not to worry, this is not urgent, as overgrowth of a tooth takes a long time to happen.
You may choose to adopt a wait-and see approach, and remove the upper wisdom teeth when it starts to give you problems.
Hope this helps, all the best.
