Tooth Pain
You have chronic pain in your teeth. Any action that requires concentration (e.g., maintaining a spell) requires a successful DC 10 + (IE) Constitution saving throw per round to maintain concentration. The pain makes talking difficult, causing a penalty of −(IE) on social Charisma checks, and spells with a verbal component require a successful DC 8 + (IE) Dexterity check to cast successfully. Because this also causes eating difficulty, you must succeed on a DC 8 + (IE) Constitution saving throw to maintain concentration while eating or drinking. Because you’re used to managing pain, even though this doesn’t reduce the experience of pain, you have a +(IE) bonus to saving throws against psychic damage.
