Some tips for preventing oral health problems like gum disease and tooth decay include:
Brush your teeth at least 2 times a day with a toothpaste that has fluoride. Floss and rinse with an antiseptic mouthwash at least once a day.
Visit your dentist two times a year for a professional oral examination and cleaning.
Eat a well balanced diet.
Avoid sugary or starchy snacks.
Ask your dentist if he thinks you should use an antimicrobial mouth rinse.
If you have dry mouth, ask your dentist about treatments for this condition, such as artificial saliva. Biotene is one product and is available over the counter.
