How to have healthy teeth all our life

1- How often should we visit our dentist?

We should be visited by our dentist every 6 months or twice a year. This makes it possible for the dentist to examine our teeth and prevent the extension of oral diseases which can result in complicated dental therapies, high cost and discomfort. Dentist can manage future visits on the basis of his diagnosis.

2- How long is the duration of tooth brushing?

Access to all tooth surfaces to clean bacterial plaque requires some time. You should brush your teeth at least 2-3 minutes twice a day. Unfortunately many people brush their teeth for only 45-70 seconds.

3- Is there any method to lessen acidic bacterial products in conditions in which I can’t brush?

Washing mouth with water after food can decrease bacterial count up to 30% and neutralizes acidic products. You can also use a piece of cloth or gauze to clean your teeth until you can brush them.

4- What kinds of foods are damaging to our teeth?

Sticky foods that adhere to tooth surfaces and contain a lot of sugar, like chocolates, need a long time to be cleaned on tooth surfaces by salivary flow. Generally foods that are suitable for body are also appropriate for teeth. For example hard and fibrotic foods such as vegetables, Fruits, and seeds massage the gingiva and can also clean the teeth to some extent.

5- How should sensitive teeth be treated?

Tooth sensitivity can be decreased by special tooth pastes, sealants (Dilute plastic materials used to seal the tooth fissures to prevent dental caries), and dental filling materials containing fluoride. Eating less acidic foods in our diet can help reduce tooth sensitivity.

6- What is the role of fluoride in dental health?

Fluoride is found as a composite in nature. It exists in water, weather, and soil. Fluoride is readily absorbed by tooth enamel. Fluoride strengthens teeth during their morphogenesis, and increases their resistance to dental caries. Early carious lesions can rematerialize when exposed to Fluoride.

7- What kind of brush is suggested for cleaning the teeth?

Brush tip should be appropriate so that all areas of the mouth, teeth, and gingival could be accessible. Its handle should be broad and long enough so that one can grasp it easily in his hand.
Bristles should be made of soft nylon and should have a round tip so that it does not damage gingival.
They should be changed every 3-4 months. It should be changed earlier if bristles are damaged (more than normal separation of bristles is one sign of damage) or in case of catching cold or having influenza.

8- What kind of tooth paste and mouth wash are best?

Most of toothpastes available at groceries are basically the same.
Be sure that your toothpaste contains fluoride. All of the toothpastes containing fluoride are effective against plaque and dental caries and can clean and polish tooth enamel.If your teeth are sensitive to cold and heat, you should use toothpastes that are made for this purpose. Toothpastes usually contain compositions that make brushing favorable.

9- Why should we use dental floss?

Using dental floss is an important stage in dental health care which is neglected by most of people, and usually no time is spent for it. Regular use of dental floss increases the chance of having healthy teeth, and decreases the chance of gingival and periodontal diseases. Dental floss eliminates the interproximal bacterial plaque, and increases gingival blood flow.

10- Are bleaching dental materials found at groceries advantageous?

These materials contain bleaching compositions. But it should be remembered that many of these drugs contain abrasive particles which is damaging to dental health. These materials should be used under supervision of dentists.

11- What is the cause of halitosis?
