Brushing your teeth is a very important part of oral hygiene. It should be done at least twice a day or if possible, after each meal. It is advisable to use a toothpaste with fluoride and to clean between the teeth with an interdental brush, dental tape or silk. Both should be undertaken using an appropriate brushing technique.
Dentists recommend changing your toothbrush every 3 months because:
- Over time the filaments of the brush can deteriorate. Filaments which become worn are unable to eliminate the buccal biofilm with the same efficacy as those which are still intact. In addition, using a toothbrush in a poor condition can potentially damage the gums and increase bacterial contamination.
- Toothbrushes are the ideal medium for bacteria growth, especially when the filaments are wet. The contamination of the toothbrush occurs shortly after the first use and increases with time. Contaminated brushes can become a source of infection within the mouth. As a result, changing your toothbrush every 3 months enables you to achieve a good oral hygiene.
The accumulation of microorganisms is inevitable however you can follow a few tips in order to minimise it.
- Rinse your toothbrush with water after brushing, ensuring all toothpaste is removed as well as any residue that may remain stuck to the filaments.
- Remove excess water, store your toothbrush in an upright position and allow to air dry until it is used again. A humid environment is more favourable for the growth of microorganisms.
- Use a toothbrush with a protective cap with holes. This will help keep the toothbrush in optimal hygiene conditions whilst facilitating the necessary ventilation.
- Change your toothbrush every 3 months or when the filaments start to deteriorate.
