Brushing and toothpaste
What is importance of brushing?
The single best way to remove harmful plaque—a thin, sticky film loaded with bacteria—from teeth and gums is to brush teeth regularly and properly.
Proper teeth brushing techniques
Because every mouth is different, there is more than one technique of brushing that has proven to be effective. Deciding which technique is most appropriate for you depends largely on your teeth position and gum condition. Consult your dentist to determine which brushing technique is most appropriate for your mouth. Generally, most dentists recommend a circular technique for brushing. This includes brushing only a small group of teeth at a time—gradually covering the entire mouth. The importance of maintaining a circular or elliptical motion is emphasized, as using a back and forth motion may cause the following:
- Receding gums
- Exposed and sensitive root surface
- Wearing down of the root surfaces at the gum line
Instead, dentists recommend the following method:
- Place the toothbrush beside your teeth with the bristles pointed at the gums at a 45-degree angle.
- Gently brush only a small group of teeth at a time (in a circular or elliptical motion) until the entire mouth is covered.
- Brush the outside of the teeth, inside of the teeth, and the chewing surfaces.
- Gently brush the tongue to remove bacteria and freshen breath.
- Repeat steps one through four at least twice daily, especially after meals and snacks.
Types of toothbrushes
A toothbrush head should be small—about 1 inch by 1/2 inch—and should have a handle suitable for firm grasping. The bristles of the brush should be soft, nylon and rounded at the ends. This helps ensure that the brush bristles are kind to the gums and tooth surfaces. Soft, polished bristles allow you to reach into the crevice (sulcus) between the teeth and gums to remove plaque without damaging the gums. Some brushes are too abrasive and can wear down the enamel on teeth. Thus, in most cases, medium and hard bristles are not recommended. Only gentle pressure is needed when brushing to remove the plaque. Excessive pressure can cause the gums to recede and abrade (wear down) the tooth surface.
Generally, brushing is recommended twice a day for at least three to four minutes each time. Patients generally think they are brushing long enough, when in fact, most people spend less than one minute brushing. In addition, it is generally better to brush three to four minutes twice a day instead of brushing quickly five or more times throughout the day.
Dentists advise brushing your teeth during the day while at work, school, or play. Keeping a toothbrush handy—in your desk or backpack—increases the chance that you will brush during the day. Replace your toothbrush every two to three months.
What is in toothpaste?
Also called dentifrice, toothpaste is composed of the following cleaning ingredients (stated in approximate percentages):
- Humectant (helps retain moisture) and water (75 percent)
- Abrasive (20 percent)
- Foaming and flavoring agents (2 percent)
- pH buffers (2 percent)
- Coloring agents, binders, and opacifiers (1.5 percent)
- Fluoride (.24 percent)
Brushing with toothpaste (particularly toothpaste with fluoride) helps to:
- Remove plaque
- Resist decay
- Promote remineralization (strengthening enamel that has been attacked by acids)
- Clean and polish teeth
- Remove teeth stains
- Freshen breath
Types of toothpaste
Fluoride is the most crucial ingredient in toothpaste. As long as the toothpaste contains fluoride, the brand or type (paste, gel, or powder) generally does not matter. All fluoride toothpastes work effectively to fight plaque and cavities, and clean and polish tooth enamel. The brand you choose should bear the ADA (American Dental Association) seal of approval on the container, which means that adequate evidence of safety and efficacy have been demonstrated in controlled clinical trials.
Some toothpastes offer tartar control pyrophosphates to prevent the buildup of soft calculus deposits on teeth, while others offer whitening formulas to safely remove stains, making teeth brighter and shinier. But, contrary to clever advertising and popular belief, fluoride is the true active ingredient that works the hardest to protect your teeth.
