Tefillin need to be square, a dent in one of the corners can make them no longer Kosher. They do not have to be pointy on the corners, however if you, your son or husband have a serious dent like in the picture below, or if you are not sure how severe it is, bring them in right away to be inspected and if necessary fixed.
Sometimes nicks and dents can go undetected, which is one of the reasons why it is important to have Tefillin checked on a yearly basis. If that is not feasible then at least once every 5-7 years.
Remember; always handle Tefilin over a table or surface to prevent them from falling to the ground. It is also important to stay away from walls or low ceilings while wearing them.
