Severe toothache can be relieved by taking appropriate painkillers, such as fenbendazole or ibuprofen. Most of the causes of tooth pain are caused by the nerve source of pain, so the treatment by painkillers and anti-inflammatory drugs alone cannot completely achieve the effect of pain relief, and it is recommended that patients go to a dental hospital or specialist outpatient department for medical treatment to avoid aggravation. If the pain is caused by periodontitis, or by gum abscess, you can take some antibiotics such as amoxicillin and metronidazole to relieve the pain. Patients must pay attention to a light diet during treatment, eat more foods rich in vitamin B, eat more fresh fruits and vegetables, avoid spices, and pay more attention to oral hygiene in general, rinse your mouth after meals, brush your teeth 3 times in the morning, noon and night, etc.
