Many different types of bacteria live in our mouths and build up on the teeth in a sticky film called dental plaque. When we eat and drink, these bacteria create acids, which can dissolve the protective layer beneath the retained plaque. The acid removes minerals from the enamel, which if left untreated can cause a cavity. Decay begins in the main portion of the tooth (the enamel) and as the enamel is broken down the decay can go deeper into the dentin and can eventually reach the nerve (pulp) of the tooth.
Your dentist can diagnose cavities by examining the tooth surface and by taking an x-ray to see if the cavity has gone from the enamel into the dentin or pulp of the tooth.
There are a variety of ways to help prevent cavities which include: Brushing and flossing daily; this will help reduce the amount of dental plaque and bacteria in your mouth. Eating sugary or starchy foods less often during the day to help reduce the amount of tooth-damaging acids in your mouth. Use of fluoride toothpaste, which strengthens teeth, as well as fluoride treatments provided by the dentist or taking fluoride supplements as recommended by the dentist. Using antibacterial mouth rinses to reduce the levels of bacteria that cause cavities. Chewing gum that contains xylitol; this can help decrease bacterial growth.
In adults, dentists can apply sealants on molars that have early signs of tooth decay, as long as the decay has not broken through the enamel. Once the enamel has been irreversibly compromised, your dentist will have to fill the tooth. In more serious cases, a root canal may be necessary. In children, both baby molars and permanent molars can be sealed. Dentists can also apply fluoride varnish on both primary and permanent teeth to protect them from decay.
If left untreated, a cavity will cause the tooth to decay significantly. Eventually, uncontrolled decay may destroy the tooth completely. There is also the risk of developing an infection related to an abscess when the infection spreads to the root of the tooth.
