The best Listerine formulation is the one that works best for you. You may need to try several variations of Listerine before you find the one you prefer. You can also speak to your dentist for advice n which Listerine they recommend.
Listerine offers a range of different flavours including ginger and lime, cool mint and fresh burst. Milder tastes are available, such as mild berry, if you find the normal Listerine mouthwashes to be too strong.
Listerine also have a range of alcohol-free mouthwashes under the Listerine Zero range.
