Found a Bump Inside Your Lip? 

1 in 10 US adults find one every year. Most are harmless. Here's how to be sure.

95% Are Harmless 

Nearly every white bump is one of 5 ordinary conditions. Cancer is statistically rare. 

Meet the 5 Suspect

Mucocele, canker sore, cold sore, Fordyce spot, or oral thrush — one of these is yours. 

Does It Hurt When You Press? 

Sharp pain = canker sore. Painless dome = mucocele. Burns or tingles = cold sore. 

The Lip-Bite Bump 

Soft, bluish-white, painless dome? It's likely a mucocele. Heals in 3 to 6 weeks. 

The Stinging Ulcer 

Yellow center, red ring, stings on citrus or soda? Classic canker sore. 

The 14-Day Home Fix 

Warm saltwater rinses, soft toothbrush, SLS-free paste, OTC gel. That's the kit.

Never Pop It 

Popping a mucocele almost always makes it refill — and invites infection.
