The embodiments herein discloses a composition and method for the synthesis of an effervescence producing tablet for reducing and eliminating a mouth odor and oral staining caused by ingested beverages and food. The method comprises mixing excipients, disintegrating agents, flavor and sweetener in a V-blender. The lubricant is added V-blender to obtain a mixture. The mixture is compressed on tablet press equipment with a round tooling. The tablets are packaged in a foil pouch. The “excipients” in the effervescent tablet composition are malic acid, sorbitol, potassium bi-carbonate, microcrystalline cellulose, sodium chloride, sodium carbonate and magnesium oxide. The malic acid react with potassium bicarbonate or sodium bicarbonate or sodium carbonate to form an effervescence reaction to induce tablet disintegration, provide a pleasant sensation in the mouth, and to clean a wine stain in the mouth.
