Last but not least, here is an alternative for pregnant women who would like to opt for a flavourless toothpaste. This is an organic toothpaste Singaporean stores vouch for. This is certified safe for use of infants 6 months and older. Calendula extracts have anti-inflammatory effects which help with teeth sensitivity. Apart from flavourless toothpaste, there are also fruity options (Banana, Blueberry, Raspberry, Strawberry, Blackcurrant), leaving you spoilt for choice.
