Side effects / Teeth and gums
Written from FDA labels, published studies and buyer reviews. Our own test of each gum comes next. Updated 14 Nov 2026.
The label warns about fillings and jaw problems. No study that we found measured tooth damage from the gum itself.
Because Nicotine Polacrilex Gum is a gum-based product, chewing it can cause dental fillings to loosen and aggravate other mouth, tooth and jaw problems.
Nicotine gum user guide, FDA label dataNo study shows that it does. The evidence for receding gums comes from pouches and snus, which sit in one spot.
A review of 42 lab studies concluded that nicotine at the levels gum users reach is unlikely to kill gum cells. Cell studies are not mouths, so treat that as a weak signal.
The trials point the other way. In 200 smokers, nicotine gum reduced tooth stain over 12 weeks.
Buyers do report a yellow tongue from some 4 mg gums. The FDA labels show why: most 4 mg pieces contain the dye D&C Yellow 10, and most 2 mg pieces do not.
I mean they work but the color of the gum turns your whole mouth and teeth neon yellow.
Amazon buyer, Blip Fruit Freeze 4 mgThe label names fillings only. We read 100 nicotine gum labels and found no mention of dentures, crowns or braces.
Buyers call uncoated gum the hardest to chew.
It’s non coated and it’s so hard to chew I’m scared I’ll break a tooth
Amazon buyer, Rugby uncoated Mint 2 mgYes. The label lists jaw problems and tells you to stop and ask a doctor if they occur.
The label method has you chew for only part of the half hour. The piece rests in your cheek for the remainder.
It can. Mouth irritation and mouth ulcers were among the reasons people stopped the gum in a five-year study.
Each was a reason for at least 5% of the people who stopped.
No. The American Dental Association says these sweeteners do not cause cavities.
Every gum in this guide is sugar-free. The association has not said if nicotine gum can carry its seal.
No study shows that it does. Reviewers call the evidence on nicotine itself inadequate, in either direction.
We found no long-term study of nicotine gum and cancer.
