ToothGuard represents a new generation of advanced oral probiotics scientifically developed to protect the teeth and gums. It works by crowding out the bad bacteria - leaving them nowhere to hide, and colonising the mouth with good, healthy bacteria.

The mouth is a constant battleground – on a daily basis, billions of invading bad bacteria attempt to displace the natural and beneficial bacteria of the mouth, teeth and gums. This causes a change or imbalance of the normal bacteria in our mouths and can affect the dental health of our teeth and gums.

Tooth decay and gum disease are the byproducts of nasty bacteria that are tough to get rid of, no matter how good your dental routine is.

ToothGuard contains a 30-day supply of pleasant tasting sugar-free lozenges that do not need to be refrigerated. In conjunction with a good oral care routine, one lozenge a day is all it takes to give you and your family the highest potency of BLIS M18™ you will find. 

ToothGuard contains BLIS M18™, a new generation of advanced oral probiotic, developed from a specific strain of beneficial bacteria called Streptococcus salivarius that is found to occur naturally in the healthy mouths of adults and children.  While everyone has this bacteria in their oral cavity, very few have high quantities of the specific Streptococcus salivarius M18 (BLIS M18™) strain.

This product is developed and manufactured under strict quality control systems in our facilities in Dunedin, New Zealand.

For best results, slowly dissolve one lozenge in the mouth 1-2 times a day, ideally after brushing. ToothGuard with BLIS M18™ works best if eating or drinking can be avoided for at least 30 minutes after taking. The longer BLIS M18™ is in your mouth, the better the colonisation will be, and the more the bad bacteria can be crowded out.

Suitable for adults from age 13.

ToothGuard can be taken during pregnancy or breastfeeding.

Do not take ToothGuard while taking antibiotics.

If you have an immune compromised condition, please seek your doctor’s advice before taking.


30 Lozenges per pack.

Per Dose: Isomalt, Tableting Aids, Streptococcus salivarius M18 (contains at least 2.50 billion CFU/dose at the date of manufacture), Natural Flavour.
