Lemon water isn’t a cure-all, but used correctly it can be a steady daily aid. Fresh lemon, warm (not hot) filtered water, and a modest ratio—about half a lemon in 8–12 ounces—deliver vitamin C and digestive support while limiting tooth and stomach irritation, especially when sipped through a straw. Taken in the morning it helps rehydrate and gently wake digestion; at night, a much weaker mix can ease bloating without reflux. Skip sugar, avoid boiling water, and wait before brushing—small adjustments that make it work for you, not against you.
