The patient may have had an extraction or other dental surgery performed earlier in the day and now has excessive bleeding at the site and is unable to visit the dentist. The patient may also be using aspirin, warfarin, or direct-acting oral anticoagulants (DOACs) such as apixaban, dabigatran, or rivaroxaban. In addition, patients may be taking aspirin in combination with one of the newer dual antiplatelet therapy (DAPT) medications: clopidogrel, prasugrel, or ticagrelor.
