A sudden and severe pain that is located in a specific part of your mouth can have many causes. A cavity, a chipped tooth, loose filling or exposed root can all cause this type of toothache. Another common cause of a severe toothache is an abscessed tooth, which is also referred to as an infected tooth. You can visit emergency dentists to get a diagnosis and treatment for the pain caused by a tooth infection.
Diagnosing an Infected Tooth
In most cases, an emergency dentist only needs to do an oral examination to diagnose an infection of a tooth. The signs of an infected tooth include swelling of your gum tissue, swelling of your face near the location of the tooth, severe pain, fever, redness and pus around the site of the infection. In some cases, the dentist may perform an x-ray to determine the extent of the infection, such as to see if it goes into your bone tissue.
Relief of Pain
After the diagnosis of an infected tooth is made, your dentist will offer you some options to relieve the pain. A local anesthetic such as lidocaine can be injected into your gum tissue. This medication numbs the area so that your nerves do not transmit pain signals to your brain. The dentist may also do this if your tooth requires any additional care, such as the replacement of a filling, root canal therapy or scaling of your gum tissue.
Treatment of the Infection
Your dentist may need to treat the infection before any additional dental procedures can be performed. This is because the infection could spread further in your mouth if it is not promptly treated. In most cases, your dentist will prescribe oral antibiotics. You will take the medication for 7 to 10 days in liquid or pill form. For a severe infection, you may receive an antibiotic injection.
