Many people ask me what the best toothpaste is. I recommend the best toothpaste is the one that you like the taste and texture of.
Toothbrushing with no toothpaste will be able to remove plaque and debris from your mouth effectively.
The main purpose of toothpaste is to deliver fluoride, to strengthen your teeth against decay. There are some more abrasive toothpastes to help remove stains. Specialised toothpastes, like sensitive toothpaste also contain chemicals to desensitise your teeth from hot and cold foods.
The flavours of the toothpaste will also help freshen your breath.
