We need more information and photos please. How old is the oak? Are only a few branches affected? Any changes in the surrounding area? Has this happened before?

Without more information such as type of oak and a picture of the leaves and entire tree we cannot assess the problem. There are multiple reasons for dark edges on oaks. Some are minor such as drought related; others are fatal such as oak wilt. Compare what you are seeing with the following website. If this is a high value tree you may want an onsite assessment by a certified tree professional. See the second website.
