Why is it important to brush your teeth twice a day.Brushing your teeth twice a day with a fluoride toothpaste can prevent tooth decay and gum disease. Concentrate on the nooks and crannies to make sure you remove as much plaque and leftover bits of food as possible.

• Put a pea-sized blob of fluoride toothpaste on your toothbrush.
• Using small circular movements, to brush your teeth,
• Don't forget the hard-to-reach bits at the back of your mouth and behind your teeth.
• Brush along the gum line as well as the teeth themselves.
• Brushing your teeth should take about 2 minutes.

Step 2: Clean Between Your Teeth

As a wise dentist once said, "You don’t have to floss all your teeth—just the ones you want to keep!"

How to floss?

1. Use enough floss. Break off a piece about 18 inches long. That sounds like a lot, but you want enough to keep a clean segment in place as you move from tooth to tooth. Wrap most of the floss around either the middle finger or the index finger of one hand, whichever you prefer, and a small amount onto the middle or index finger of the other hand. (Using the middle finger leaves your index finger free to manipulate the floss.)
2. Slide between teeth. Gently guide the floss up and down against the sides of the teeth and under the gum line.
3. Form a “C”. Make a C shape with the floss as you wrap it around the tooth. Then carefully pull the floss upward from the gum line to the top of the tooth.
4. Roll along. As you move from one tooth to the next, unroll a fresh section of floss from the finger of one hand while rolling the used floss onto the finger of the other hand. Use your thumb as a guide.
5. Don’t forget to floss the back side of each tooth.

If you have a tough time reaching certain parts of your mouth to floss, ask your dentist about interdental brushes, floss aides, or water- or air-flossing devices.

Step 3: Use a Mouthwash

 Some mouthwash freshen breath, others provide an anti-cavity benefit from fluoride, while others contain germ-killing ingredients to help prevent plaque buildup.

Choose the right mouthwash for you by choosing one that meets your dental hygiene needs for the health of your teeth and gums, and your taste preference.

Keep these points in mind when choosing
1.Alcohol—yes or no?

Alcohol is a component of many mouthwashes and rinses, which can be problematic if a large quantity is deliberately swallowed. If you want to buy a mouthwash for the whole family, and your household includes school-aged children or teens, you may want to choose from among the alcohol-free mouthwash products that are available. Also, some recovering alcoholics avoid mouthwash with alcohol because of the potential for abuse.

2. Sensitivity.

Some people find the ingredients in mouthwash irritating, especially people who have sensitive gums. If you have a sensitive mouth, consider an alcohol-free or natural mouthwash. Natural mouthwashes often contain ingredients such as aloe vera and chamomile for a soothing effect.

3. Plaque control.

 If you want a mouthwash that not only helps control bad breath but also helps to prevent plaque buildup on the teeth, look for one that contains anti-plaque ingredients.

If you’re uncertain about which mouthwash or rinse would best meet your oral health needs, ask your dentist or dental hygienist for suggestions.

Step 4: Avoid Sticky, Sugary Food

The hardest foods to remove from your teeth are the ones that cling when you chew. Think raisins, granola bars, or sticky candy. If sugar is not removed from your teeth shortly after you eat it, plaque uses it to help create tooth decay. 

Step 5: Go to the Dentist

See your dentist and dental hygienist on a regular basis, so they can look for signs of disease.

How often you have to go will depend in part on how well you care for your teeth. Most people have to visit only twice a year.
