There are several mouthwashes that can help with gum disease, and the best one for you will depend on your specific needs and preferences. Here are some of the best mouthwashes for gum disease, along with their positive and negative aspects and ingredients:

3. Listerine Ultraclean Antiseptic Mouthwash: This mouthwash effectively fights against bad breath, plaque, and gingivitis. It provides a refreshing feeling and is a good choice for those looking for a mouthwash that can help with gingivitis.

4. Crest Pro-Health Multi-Protection Mouthwash: This mouthwash fights plaque, gingivitis, and bad breath without the harsh burn of alcohol. It kills 99% of germs and reduces gingivitis when used twice daily.

When choosing a mouthwash for gum disease, look for one that contains antibacterial ingredients such as chlorhexidine, cetylpyridinium chloride, and essential oils, which can help kill bacteria and reduce plaque and gingivitis. It is also important to consider any potential negative aspects of the mouthwash, such as sensitivity or strange taste, and to be mindful of the directions for use. Remember that while mouthwash can help reduce plaque and tartar buildup, it cannot cure periodontal disease, which requires professional treatment.
