Oral infection can be any kind of infection that affects the tooth and some parts of the oral cavity like the gums around the teeth. When talking about tooth infection, this usually involves the nerves which are the geometric center of the tooth and feeds out through the end of the root. When these nerves in the tooth die, it becomes an opening for opportunistic microorganisms to enter and infect not just the tooth but the surrounding areas as well.
Any kind of damage to the teeth is the precursor to having a tooth infection. It can be through a trauma or cavities, but once your teeth get damaged, the nerves inside your teeth become vulnerable. Harmful microorganisms see this as an opportunity and will try to attack the damage teeth and the nerve in it. If the microorganisms win, the nerve of your tooth will die and this is how a simple tooth cavity or trauma becomes more dangerous.
Once the infection sets in, the supporting bones of the tooth and the adjacent tooth will be eaten away. This infection will make you lose one or more of your teeth and could also cause swelling of the gums around the infected teeth. But it is not just the teeth that will be affected. There is a possibility that other parts of your face may swell as well. If left untreated, the swelling could affect your jaws and possibly impair your swallowing reflex and finally shut off the airway passage.
There are 3 types of oral infection. They have their own different characteristics but one thing common about them is the fact that they can cause so much pain. The first type of oral infection is when the infection is inside your tooth (the living pulp tissue). This usually results from severe irritation or tooth decay. Normally, the body would send out its defensive warriors to fight off with the infection. But in the case of tooth infections, this is not possible. There is no room for the white blood cells or the antibodies and that is why they break down. Even antibiotics can't fully help the teeth recover from this kind of infection.
