You’ve had a tooth extraction procedure done and everything seems to have gone well. Then, you start to feel some discomfort in the area where the tooth used to be. It starts with a throbbing in your mouth. The pain begins to worsen and you feel as if you are being stabbed. You may be suffering from a dry socket and you need to go back to the dentist right away. What is a dry socket? Medically known as alveolar osteitis, a dry socket is an inflammation of the area that the tooth lives in (the socket). Tooth sockets are found on the upper or lower jaw and keep our teeth in place. During an extraction procedure, the infected tooth is removed leaving the socket exposed. A blood clot should form in the area as our body starts to heal itself. However, should a clot not form, you’ll be left with a dry socket. What are the causes? A dry socket following tooth extraction has many causes:
- Smoking: The chemicals in tobacco products slow down the body’s natural healing process and contaminate the wound site. Nicotine decreases the mouth’s blood supply which could lead to a failure for a blood clot to form at all after tooth extraction. Furthermore, the physical act of inhaling can dislodge the blood clot (if it’s had a chance to form) and cause you great pain.
- Straw use: Like inhalation, the sucking motion we use to drink from straws can also dislodge the blood clot. If you must drink from a straw following a tooth extraction, sip carefully.
- Oral contraceptives: Some forms of birth control pills are so high in estrogen that they hinder the body’s healing process. Before your tooth extraction, your dentist will take a detailed medical history and ask you what medications you are on. It’s important to let your dentist know if you are using oral contraceptives.
- Wound care: After your extraction, your dentist will give aftercare instructions. If you do not follow these instructions carefully, you run the risk of getting a dry socket.
- Bacteria: A preexisting infection in the mouth can stop a blood clot from forming following tooth extraction. If you have periodontal disease or other bacterial infections like strep throat you could find yourself with a dry socket. Your dentist will not perform the extraction if they notice that there are too many bacteria in the mouth.
- Hormones: If your hormones are out of whack, it’s possible that you will end up with a dry socket. For this reason, pregnant women cannot undergo certain dental procedures like tooth extraction.
- Poor blood supply: People with bad circulation and poor blood supply will find themselves with a dry socket because their blood simply won’t clot after the extraction.
