Hi welcome to the health care magic and thanks for asking your query here There may be several reasons for this kind of dental pain ,This may be due to a cervical abrasion of teeth causing hypersensitive or it may be related to any tooth which has invisible crack or decay and needs to be treated by root canal As you have veneered your 4 front teeth it is also possible that your pain is originating from any of them But as your dr is saying all the teeth are ok than this kind of pain may also be related to Trigeminal neuralgia (TGN) which is stabbing pain and confined to the half of your face either right or left TGN can be triggered by any activity like shaving or even a blow of air to your face can Trigger severe stabbing pain I would finally advise you to visit a Oral and Maxillofacial surgeon to get it examined further to rule out the exact underlying issue I hope it help Thanks and get well soon
