Toothpaste provide a little mechanical help with brushing plaque off your teeth. That's the main reason they exist.
Here's what to look for if you try a new brand:
- ABRASIVES
Particles of grit help to scrape bacterial plaque from your teeth. Some common abrasives include calcium carbonate, silica, aluminium oxide, and magnesium carbonide. Charcoal can also act as an abrasive, but some dentists caution that charcoal can be too harsh.
- FLUORIDE
Bacteria are constantly attacking and eroding tooth enamel, and your teeth are constantly trying to build themselves back up. (Saliva naturally contains calcium to aid in this process.) This process, called remineralization, is helped along by fluoride.
All toothpastes that have a SABS seal must contain fluoride.
If you have a specific reason why you need to avoid fluoride, ask your dentist about an alternative.
- INGREDIENTS FOR TEXTURE AND FLAVOR
Most toothpaste variants also contain flavourant and artificial sweeteners (eg. xylitol, saccharine).
