The origins of any problems in your mouth can be traced directly to one nasty little protagonist- plaque. This forms from bacteria left behind and if it is not removed, it can harden into tartar, strangle the life out of your gums and infect them. Whilst this is going on, acids will be tearing away at the surfaces of your teeth and if they get inside, the pulp and roots will become diseased. Soon the tissue below the roots will become infected and with nowhere to go, an abscess will form. You will soon know about it too: not only will it become viciously painful- your face will swell like a balloon- but it will become viciously dangerous as well. As soon as an abscess erupts, it starts poisoning your blood and is carried into the brain; the upshot is that these toxins can induce a coma that in some cases has proved to be fatal. Find a dentist or go to the hospital in the city of Leeds fast because you need to be pumped with antibiotics in order to stop the poisoning and to reduce the swelling; only then can a dentist get to work on repairing the damage. All of this is down to poor oral hygiene so you should address this immediately, but be warned: if you have had an abscess once, there is a good chance of it coming back and if it does, the only way you can nip this in the bud is to have the tooth removed.
