1. Antiplaque and whitening focus
   This toothpaste is formulated to fight plaque and tartar while removing surface stains for a brighter, naturally whiter smile with regular brushing. Calcium carbonate and hydrated silica act as mild polishing agents, helping lift stains and plaque film without harsh abrasives.​

2. Fluoride-free formula
   The Fennel variant is completely fluoride free, aimed at adults who prefer to avoid fluoride but still want tartar control and whitening support. Antiplaque performance comes from mechanical cleaning and minerals such as zinc citrate (in many sizes) rather than chemical anticavity actives, making it a natural alternative within Tom’s range.​

3. Sweet herbal fennel flavor
   Instead of mint, this toothpaste uses natural fennel oil and related herbal flavors to create a sweet, licorice‑like taste that many people find smoother and less intense than strong mint. The fennel flavor freshens breath in a more herbal way, which can be especially appealing to users sensitive to menthol or who simply prefer a non‑mint profile.​

4. Naturally derived ingredient base
   Key ingredients include calcium carbonate, glycerin, water, xylitol, hydrated silica, sodium lauryl sulfate, carrageenan, sodium bicarbonate, and natural flavor (fennel). The formula contains no artificial preservatives, artificial colors, or artificial sweeteners and is not tested on animals, aligning with Tom’s of Maine’s natural and cruelty‑free standards.​

5. 3-pack format and daily use
   Each tube contains 4.5 oz of paste, and this listing bundles three tubes, providing a convenient stock for multi‑bathroom homes or several months of twice‑daily brushing. Used for about two minutes, at least twice a day, this fluoride‑free antiplaque and whitening formula is intended to keep teeth smoother, reduce tartar buildup, gently brighten your smile, and leave a distinctive fennel‑fresh aftertaste.
