How It Works
Chew one piece for 15 to 20 minutes after meals. Hydroxyapatite, xylitol, and botanical resins stay in contact with the teeth while you chew. This complements brushing and flossing. It does not replace them.
Ingredients List
Every flavor starts with a chicle gum base, xylitol, erythritol, mastic, spruce, acacia, and myrrh. Mastic Mint adds hydroxyapatite, calcium, magnesium, zinc, and a mint terpene blend. Berry adds fruit powders. Cinna-Mastic adds Ceylon cinnamon. Honey Bun adds honeycomb and honey. Tropic Twist adds tropical fruit. No gluten, aspartame, or sucralose.
Scientific Studies
Published research has looked at xylitol and nano-hydroxyapatite in oral care. A 2025 review in the journal Biomimetics found hydroxyapatite promising as a biomimetic ingredient for enamel-focused care. Much of that research used toothpastes and gels rather than gum, and product-specific trials on this gum are limited. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
Instructions
Chew one piece after meals, or whenever you want a clean-mouth break. Replace a piece you set aside within a day or two. Keep xylitol away from dogs.

★★★★★ All the flavors are great.
All the flavors are great. Chewiness is inconsistent. Some are more firm, which I prefer. Some are a bit soft. Nice chewing on natural gum.
FREQUENTLY ASKED QUESTIONS
What does Underbrush gum do that regular sugar-free gum doesn't?
Most sugar-free gums freshen breath and stimulate saliva. Underbrush pairs that with minerals and botanicals studied in oral care, including hydroxyapatite and xylitol. It complements brushing and flossing. It does not replace them.
What are the key ingredients, and do they differ by flavor?
Every flavor uses a chicle gum base, hydroxyapatite, and resins such as mastic, spruce, myrrh, and acacia, sweetened with sugar alcohols. Mastic Mint adds calcium, magnesium, zinc, and mint terpenes. Berry adds fruit powders. Cinna-Mastic adds Ceylon cinnamon. Honey Bun adds honey. Tropic Twist adds tropical fruit.
Is there research supporting the ingredients in this gum?
There is published research on xylitol and nano-hydroxyapatite in oral care, including a 2025 review in Biomimetics. Much of it studied toothpastes and gels rather than gum. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
How long should I chew each piece, and how often should I replace it?
Chew each piece for about 15 to 20 minutes after meals. If you set a piece aside, replace it within a day or two.
Can this replace brushing and flossing?
No. Underbrush is a between-meal addition to brushing, flossing, and professional dental care.
Is it free from common allergens and artificial ingredients?
It is made without gluten, soy, dairy, artificial flavors, artificial colors, or artificial sweeteners. It is sweetened with xylitol and erythritol. Check the ingredient list if you have a sensitivity.
What is the Underbrush gum base made from?
A chicle gum base: chicle, candelilla wax, and citric acid, rather than a plastic gum base.
What does each flavor taste like, and how long does the flavor last?
Mastic Mint is clean and resinous. Berry is fruit-forward. Cinna-Mastic is warm cinnamon. Honey Bun is honey and spice. Tropic Twist is tropical fruit. Natural flavor can fade sooner than artificial gum, and the chew stays soft.
Why is Underbrush priced as a premium product compared to regular gum?
The price reflects hydroxyapatite, botanical resins, and a natural chicle base, which cost more to produce than conventional gum.
Is this gum safe for children, pregnant users, and people with health conditions?
If you are pregnant, breastfeeding, or have a health condition, ask a qualified healthcare professional before use. Supervise young children. Xylitol is toxic to dogs, so keep it away from pets.
