Tooth decay is what causes cavities to form in your teeth. It is caused by bacteria that enters your mouth that causes acids to wear away at the tooth. Plaque. a sticky substance that contains bacteria, is always forming on teeth and gums. When you eat sugary foods or drinks, this feeds the bacteria, which produce acid as a product of digestion, causing cavities to form. If left untreated, cavities can deteriorate teeth, cause pain and infection, and even become a risk to your overall health. Therefore, it is important to know the early signs of a cavity beginning to form.
The signs of a cavity will depend on where it is located and how much it has progressed. Teeth have an outer layer (enamel), a middle layer (dentin), and an inside layer, (pulp). Some cavities may cause no signs at all and can only be detected during a regular dental exam. A dental exam can reveal cavities with x-rays, as well as a visual check during the exam, to find cavities that may not show up yet on an x-ray. Early detection of cavities is extremely important, so that the area may be treated to prevent further decay of the tooth. The earlier a cavity is detected, the less extensive the treatment will be, so it is important to practice prevention and early treatment. .
As a cavity progresses, other signs may develop, such as pain and sensitivity in the area where the cavity is located. Sensitivity to hot or cold beverages is a common sign. It is sometimes possible to see cavities as visible holes in your teeth, though small cavities can look like stains. If left untreated, a cavity can lead to a dental infection. An infection is a serious problem, and you should see your dentist right away for treatment, including an antibiotic to help clear up the infection. A dying tooth, which occurs when the cavity reaches the pulp area of the tooth, can cause an abscess.
If you have pain, it is important to contact your dentist right for proper diagnosis treatment. Your dentist can also help you prevent future cavities by providing preventative dental care. Fluoride, for example, can help reverse small cavities, and your dentist can provide safe and effective treatments. Sealants, which are casings that cover chewing surfaces, can also help prevent some cavities by protecting your teeth from the accumulation of plaque, the substance which causes cavities. If your dentist detects a cavity, the tooth can usually be repaired with a filling or crown, and the decaying area is removed to prevent further growth of the cavity.
