Most people can have a slushy after wisdom teeth removal, but it is best to check with your dentist or surgeon first. If you are able to have a slushy, make sure that it is not too cold and does not have any large chunks of ice in it. It is also important to drink plenty of fluids after having your wisdom teeth removed, so a slushy can help with that as well. Just make sure to listen to your body and see how you are feeling before having anything cold.
