3 ways ARM & HAMMER™ Toothpastes work differently to protect your teeth and gums

The key to a healthy smile? A healthy mouth.

That’s why ARM & HAMMER™ Toothpastes are powered by baking soda — a natural mineral also known as sodium bicarbonate — to protect your teeth and gums for the long-term.

Baking soda, along with fluoride, delivers the 3 A’s for a healthier mouth: rapid acid neutralization, low abrasion formula, and deep-cleaning action.

1. Rapid Acid Neutralization: How Baking Soda Neutralizes Plaque Acids

You’ve probably heard of plaque — it’s that sticky film made up of bacteria, continuously forming on your teeth and gums. The bacteria feed on the sugars and carbohydrates left in your mouth after eating or drinking, producing plaque acids that can lower your mouth’s pH.

If the pH level of your mouth drops too low, your teeth could lose precious minerals such as calcium and phosphate – minerals that help strengthen your tooth enamel through a process called remineralization. Without calcium and phosphate, enamel can begin to erode, making teeth more vulnerable to cavities.

No other toothpaste ingredient neutralizes these plaque acids better than baking soda. Because sodium bicarbonate is a base, it naturally restores the pH of your mouth back to a neutral level, reducing the amount of time your mouth is on the acidic end of the scale. That’s why ARM & HAMMER™ Toothpastes are naturally powered with the most effective levels of baking soda to neutralize harmful plaque acids.

Long-term damage from acid erosion

Neutralizing plaque acids naturally raises your mouth’s pH, and returns it to a healthy environment so your teeth can remineralize — strengthening and repairing damaged enamel to protect your teeth for years to come*. That’s good news, because while your enamel can be repaired, it can’t be replaced once it’s gone!

2. Low Abrasive Formula: How Baking Soda Cleans and Protects your Teeth Without Harming Enamel

Enamel is the hardest substance in the body — even harder than bone — and surrounds your dentin: the hard tissue layer with microscopic tunnels that lead to your nerves.

However, enamel is still vulnerable to damage by erosion-causing plaque acids and highly abrasive toothpastes. Protecting this outer layer will prevent your dentin from being exposed, which can reduce tooth sensitivity and the risk of cavities.

Healthy Enamel versus Eroded Enamel

The good news is: your toothpaste can really make a difference to your enamel. Here’s why:

  • All toothpastes use different types of abrasives to remove plaque.
  • Over time, some types of abrasive can scratch your enamel, making your teeth more vulnerable to acid erosion.
  • Relative Dentin Abrasivity (RDA) is a method used to measure toothpaste abrasivity, and its impact on dentin and enamel; toothpastes with RDA values well below the 250 maximum guideline are considered gentler on dentin and enamel than those closer to 250.

Choosing a toothpaste with a low RDA is a proactive way to protect your teeth. ARM & HAMMER™ Toothpastes have an average RDA of 85 to 90 — far lower than the 250 RDA upper guideline, and far lower than most commercial toothpastes today.

The trusted, natural baking soda in ARM & HAMMER™ Toothpastes dissolves quickly, removing plaque without damaging enamel. It’s the gentle way to protect your teeth and gums for years to come.*

while this is an average, no ARM & HAMMER™ Toothpastes have an RDA higher than 130.

3. Deep-Cleaning Action: How Baking Soda Delivers a Clean You Can Feel

Brushing your teeth twice a day not only helps prevent cavities — it leaves your mouth feeling clean and fresh, especially after a meal.

When you brush your teeth and gums with ARM & HAMMER™ Toothpastes, you’ll feel the natural, effervescent cleaning power of baking soda working right away. It quickly dissolves into an active foam to penetrate even the hard-to-reach places between teeth — for a whole mouth clean that’s different from other toothpastes.

You’ll feel it bubbling as it surrounds your teeth and spreads along the gum line, leaving your teeth squeaky clean. In fact, ARM & HAMMER™ Toothpastes remove more plaque than a non-baking soda toothpaste.

Plus, the gentle power of ARM & HAMMER™ Baking Soda safely whitens teeth and removes tough stains so your healthy smile is also a brighter one.
