A toothache is usually the result of tooth decay in most children and adults. Bacteria that live in your mouth thrive on the sugars and starches in the food that you consume.
These bacteria then form the sticky plaque and the acids produced by the bacteria eat through the enamel of your teeth, creating cavities. The first sign of a cavity is the toothache you have.
Other causes of toothache
Some other causes may include the food debris left behind in the gaps between your teeth, inflammation of the gums or roots of the teeth, trauma due to injury or grinding of teeth, sudden fracture in the tooth root, due to the formation of new teeth or teething or it could be a sinus infection which causes toothache too.
Some self-care tips
Here are a few self-care tips which can help reduce the pain and give some relief until you can see your dental specialist.
Caution in using OTC medications
Certain OTC antiseptic medicines contain benzocaine, which can cause some severe side effects. You should take care to use such ointments, gels and pain relievers containing benzocaine with caution. Benzocaine can reduce the oxygen in the blood and this can be life-threatening.
Consult your dentist
Try to reach your dental specialist as soon as possible and avoid self-medication. At least call your doctor if you have pain that persists for more than two days, fever, swelling, signs of infection including redness of gums and foul smelling discharge, finally if you have trouble breathing and swallowing.
