Tooth decay is the disease known as caries or cavities. Unlike other diseases, however, caries is not life threatening and is highly preventable, though it affects most people to some degree during their lifetime.Tooth decay occurs when your teeth are frequently exposed to foods containing carbohydrates (starches and sugars) like soda pop, candy, ice cream, milk, cakes, and even fruits, vegetables and juices. Natural bacteria live in your mouth and form plaque. The plaque interacts with deposits left on your teeth from sugary and starchy foods to produce acids. These acids damage tooth enamel over time by dissolving, or demineralizing, the mineral structure of teeth, producing tooth decay and weakening the teeth.

Ulcers are very difficult to treat. There is no proven technique that will eliminate ulcers or speed the recovery time once they appear. There are a few medications that will give temporary relief from the pain, but they need to be started as soon as symptoms appear. Ulcers will generally diminish and disappear in two weeks.

Grinding your teeth can be very damaging to the teeth and also difficult to stop. If vigorous grinding occurs at night, teeth can be worn down to the gumline because the instinctive reflex to stop does not work while you are sleeping. Grinding due to stress can only be cured by removing the stress trigger. If grinding continues, a nightguard may be prescribed to prevent ultimate damage to the teeth.

Bad breath is primarily caused by poor oral hygiene, but can also can be caused by retained food particles or gum disease. Proper brushing including brushing the tongue, cheeks, and the roof of the mouth will remove bacteria and food particles. Flossing removes accumulated bacteria, plaque and food that may be trapped between teeth. Mouth rinses are effective in temporary relief of bad breath. Consult your dentist and/or physician if the condition persists.

It is important to practice good oral hygiene, such as brushing and flossing your teeth at least twice a day. To alleviate the odor, clean your tongue with your toothbrush or a tongue scraper, a plastic tool that scrapes away bacteria that builds on the tongue. Chewing sugar-free gum also may help control the odor. If you have dentures or a removable appliance, such as a retainer or mouthguard, clean the appliance thoroughly before placing it back in your mouth. Before you use mouth rinses, deodorizing sprays or tablets, talk with your dentist because these products only mask the odor temporarily, and some products work better than others.

Bacterial plaque – a sticky, colorless film that constantly forms on the teeth – is recognized as the primary cause of gum disease. Specific periodontal diseases may be associated with specific bacterial types. If plaque isn’t removed each day by brushing and flossing, it hardens into a rough, porous substance called calculus (also known as tartar). Toxins (poisons) produced and released by bacteria in plaque irritate the gums. These toxins cause the breakdown of the fibers that hold the gums tightly to the teeth, creating periodontal pockets which fill with even more toxins and bacteria. As the disease progresses, pockets extend deeper and the bacteria moves down until the bone that holds the tooth in place is destroyed. The tooth eventually will fall out or require extraction.

Signs include red, swollen or tender gums, bleeding while brushing or flossing, gums that pull away from teeth, loose or separating teeth, pus between the gum and tooth, persistent bad breath, change in the way teeth fit together when the patient bites, and a change in the fit of partial dentures. While patients are advised to check for the warning signs, there might not be any discomfort until the disease has spread to a point where the tooth is unsalvageable. That’s why patients are advised to get frequent dental exams.

Removing plaque through daily brushing, flossing, and professional cleaning is the best way to minimize your risk. Your dentist can design a personalized program of home oral care to meet your needs. If a dentist doesn’t do a periodontal exam during a regular visit, the patient should request it. Children also should be examined.
