Hi dr! i just notice that my sublingual frenulum end of the gland is swollen but it's not painful. what could be the cause and what treatment do you ?

Stone in duct?: It's possible you have a calculus (stone) lodged at the tip of Warton's duct. The sublingual and submandibular salivary glands empty into Warton's duct, which runs beneath the tongue in the floor of the mouth. This is more likely the diagnosis if you feel a small hard lump in the same area in the floor of the mouth. This is called sialolithiasis. If the swelling persists see a physician.
