This information can differ between dental professionals and this can change depending on each personal case.
The most obvious one and the top of any list is to make sure you brush your teeth twice a day for two minutes.
If you brush your teeth after eating and drinking you should wait at least 20 minutes to avoid brushing what you have just eaten around your teeth and gums.
Second is to floss your teeth twice a day. Ideally you will do this after you have brushed your teeth.
Third is to use Tepe brushes.
A tepe brush looks a bit like a miniature baby bottle cleaner, you can get them from most pharmacies and they come in different sizes. Fourth is to use a mouthwash, but there are rules to this. We shouldn’t use a mouth wash every day, this is because the bacteria in your mouth can get use to it and stop re-acting (the same way we could get resistant to an antibiotic if used to often).
It is also advisable to use a mouth wash that does not contain alcohol as this can dry out your mouth.
Use a fluoride mouth wash about 30 minutes after having brushed your teeth. And last of all five, if you notice any bleeding during brushing you should get this checked out by your dentist.
Bleeding could be a sign of gingivitis, periodontal disease or even trauma.
