Ones healthy smile depends on simple dental care habits, such as brushing and flossing. Please follow these steps to protect you and your loved ones oral health.
Brushing for proper oral health
Consider these brushing basics from the American Dental Association:
Brush your teeth at least twice a day. When you brush, don’t rush. Take enough time to do a thorough job.
Use the proper equipment. Use a fluoride toothpaste and a soft-bristled toothbrush that fits your mouth comfortably. Consider using an electric or battery-operated toothbrush, especially if you have arthritis or other problems that make it difficult to brush effectively.
Practice good technique. Hold your toothbrush at a slight angle against your teeth and brush with short back-and-forth motions. Remember to brush the inside and chewing surfaces of your teeth, as well as your tongue. Avoid vigorous or harsh scrubbing, which can irritate your gums.
Keep your equipment clean. Always rinse your toothbrush with water after brushing. Store your toothbrush in an upright position, if possible, and allow it to air dry until using it again. Don’t routinely cover toothbrushes or store them in closed containers, which can encourage the growth of bacteria.
Know when to replace your toothbrush. Invest in a new toothbrush or a replacement head for your electric or battery-operated toothbrush every three to four months — or sooner if the bristles become frayed.
Flossing for proper oral health
You can’t reach the tight spaces between your teeth or under your gumline with a toothbrush. That’s why daily flossing is important. When you floss:
Don’t skimp. Break off about 18 inches (46 centimeters) of dental floss. Wind most of the floss around the middle finger on one hand, and the rest around the middle finger on the other hand — leaving about 1 inch (3 centimeters) to floss your first tooth.
Take it one tooth at a time. Use your thumbs and forefingers to gently pull the floss from the gumline to the top of the tooth to scrape off plaque. Rub the floss against all sides of the tooth. Unwind to fresh floss as you progress to the next tooth.
Keep it up. If you have trouble getting floss through your teeth, try the waxed variety. If it’s hard to manipulate the floss, use a floss holder or an interdental cleaner — such as a dental pick or stick designed to clean between the teeth.
Geographic tongue is characterized by harmless lesions, or patches, that can suddenly materialize on the tongue's top surface. The condition gets its name from the physical appearance of the lesions, which resemble smooth, red islands, possibly rimmed with white. Their smoothness comes from the absence of the tiny bumps or “papillae” that normally cover the entire surface of the tongue. These variations in color and texture give the whole tongue a map-like appearance.
The pattern on the tongue can change daily as the lesions appear to move or migrate, healing in one spot only to reappear in another. That's why the medical term for this condition is benign migratory glossitis. It's scary looking, but does not compromise a person's health.
Discomfort from the condition can sometimes be relieved with over-the-counter pain relievers; mouthrinses containing anesthetics, antihistamines, or steroids; and by avoiding certain irritants such as tobacco, alcohol, and foods that are spicy, salty or acidic.
No one knows exactly what causes geographic tongue. Some factors that may play a role include vitamin B deficiency, irritation from alcohol or spicy foods, and genetics.
This condition can be diagnosed simply by examining your tongue; laboratory tests are usually not necessary. Geographic tongue normally resolves on its own, but a dental professional should be consulted if you notice any changes in your tongue's appearance.
