How to choose toothpastes and toothbrush

By :
Today in market we have so many dental care products, from toothpastes to tooth brushes to mouth washes. The best strategy for selecting tooth paste and tooth brush is simply to ask your dentist or dental hygienist.


Tooth paste selection

 Ingredients of tooth paste

  • Abrasive agents: Silica compounds responsible for the abrasive action on particles and food stains on teeth besides polishing the tooth surface

  • Antiseptic agent: Like Xylitol or Triclosan which inhibits the plaque formation in oral cavity

  • Humectants- Prevents the drying up of tooth paste

  • Fluoride: Prevent cavities, makes the teeth stronger, and also remove the yellow plaques over the teeth

  • Sweetening agent: Saccharine sodium

  • Binding agent

 Important things to remember while using tooth paste

  • Not to swallow tooth paste, as this can cause fluoride toxicity, especially in kids.

  • Don’t use tooth paste for pimples or zits excessively.

  • Should brush for 2-3 minutes’, brushing vigorously for long duration does more harm than good.

  • Amount of tooth paste: Should be about size of pea.

 Tooth brush selection

 People generally take their decision making on the attractiveness of the color and design.

 The basic function of a toothbrush is to reach and efficiently clean most areas of the teeth properly.

Tooth brush that I use should be

  • A soft bristled tooth brush is good compared hard bristles, as hard bristles causes’ gingival recession.

  • Soft bristles are more flexible, clean beneath the gingival margin and do not damage the gums also.

  • Handle should be comfortable (gripping).

  • The shape of the neck or handle does not play any significant role in improving the effectiveness of a tooth brush.

  • Powered tooth brushes (electric tooth brushes) have no special advantages over the manual ones.

  • Powered tooth brushes should be used for handicapped or bedridden patients, children and patients lacking fine motor skills.

 When should I replace my tooth brush?

  • Replaced every 3 months or when the bristles start to wear

  • Need to replace the toothbrush after flu, sore throat or mouth infection. The microbes can accumulate on the brush leading to reinfection.
