How Do I Pick the Right Toothpaste?

Here are a few things to look for:

Fluoride

When choosing a toothpaste, fluoride content matters. For adults, look for a toothpaste containing around 1,450ppm fluoride. Most well-known brands in New Zealand such as Colgate, Macleans and Oral B contain this concentration. Some alternate brands may have a smaller amount.

If you are at a high risk of decay, we may recommend a higher strength of fluoride in your toothpaste which can be purchased from us or your local pharmacy.

Children need less fluoride in toothpastes, around 1,000ppm are recommended.

Sensitivity toothpastes

Products such as Sensodyne and Colgate Sensitive are specially formulated for people who experience sensitivity to cold, sweet, or brushing. They work by either blocking the tiny channels (dentinal tubules) that lead to the nerve inside the tooth — often using ingredients like strontium or arginine — or by calming the nerve itself with potassium nitrate. For best results, they should be used twice daily and can take a couple of weeks of consistent use to achieve full benefit.

Flavour

Toothpaste does not have to be mint! If strong mint flavours put you off brushing, trying a milder or alternative flavour can make the experience more pleasant and encourage consistent brushing. The most important thing is finding a toothpaste you will use twice daily — enjoyment helps build good habits.

Be cautious with highly abrasive formulas

Some whitening and smoker’s toothpastes can be more abrasive. While they may help lift surface stains, regular use can contribute to enamel wear and sensitivity over time.

Consider SLS-free toothpaste if you’re prone to irritation

Some toothpastes contain sodium lauryl sulphate (SLS), a foaming agent that can trigger irritation, dry mouth, or recurrent mouth ulcers. Choosing an SLS-free formula can be gentler on the soft tissues and more comfortable for those who notice stinging, peeling, or frequent ulcers when brushing.

After brushing spit, don’t rinse.

By spitting out the excess toothpaste but not rinsing with water, you allow the toothpaste to remain on your teeth for longer, giving it time to work more effectively.

If you’re ever unsure which toothpaste is best for you, especially if you experience sensitivity, staining, or gum concerns, feel free to ask us at your next appointment.
