The best way to keep your breath fresh and control the spread of harmful bacteria (such as those that cause gingivitis) is to rinse morning and night with the best whitening mouthwash. This freshens and sanitizes your mouth at the two most vulnerable times of day – in the morning when bacteria may have been multiplying overnight, and before bed when the results of eating and drinking during the day will sit in your mouth all night otherwise. These two times are the best defense against mouth problems, and subscribing to this daily regimen with the best whitening mouthwash you can find will give you the added bonus of a white, beautiful smile.

What Should You Know about Best Whitening Mouthwash

The best whitening mouthwash options contain a bleaching agent that gets below the enamel surface to remove stains left by discoloring and acidifying foods. These foods leave behind particles that can darken or dull the appearance of your teeth, as well as causing damage to the enamel layer. Removing these particles is best for your appearance and your health, but some people may have sensitivity to the ingredients most effective in removing them.


Hydrogen Peroxide – this bleaching agent is typically the main ingredient in mouthwash that also whitens teeth. The molecules are tiny, and easily able to access the enamel in order to lift away stains; however, this process may be too much for some users, who will experience sensitivity to cold or hot substances, or even to touch as a result. This is because thinner enamel allows the hydrogen peroxide to access the dentin layer, which is the more sensitive sub-surface of the tooth found under the enamel. This layer also contains nerve endings resulting in pain for those who are sensitive to the peroxide effects. Fortunately, this effect is temporary, and the best whitening mouthwash for you is still within reach.

How Do You Choose?

If you find you have sensitivity to peroxide or any other ingredient, you may need to do some trials of different products to find which is best. Whitening mouthwash is sold by many different brands, and each has a specific and often proprietary blend of ingredients. While one product may be too highly concentrated to give you the effect of beautiful, white teeth without sensitivity, another may be just the thing to balance effectiveness and comfort.

Safe Use

Be aware that even the very best whitening mouthwash has a high acidity level, which can do damage to teeth if used excessively. Your mouth has a natural pH level that helps you maintain healthy bacteria while still being able to breakdown food. When your pH is out of balance, it can lead to several issues such as dry mouth, infection, and tooth sensitivity and vulnerability. Think of your mouth as a delicate eco-system, and when using acidic washes, remember to restore balance by adding some alkalinity to that environment. You can purchase mouthwash with a high alkalinity level to counteract the acidity of your whitening mouthwash. It won’t negate the effects of whitening, of course, but it will maintain proper balance in your mouth, to keep your smile white and your health intact.It’s also a good idea to brush before using a whitening mouthwash – fluoride toothpaste is best.Whitening toothpaste can be a bit harsh, and the fluoride actually acts to protect the tooth from acidity.

Time It Right

Even the best whitening mouthwash can damage your teeth if not used according to the instructions on the label. Because peroxide bleach is mildly corrosive, it can eat away at the topmost lining of the tooth (called the pellicle) and make your teeth more sensitive to attack by bacteria and other hazards. It’s best to use whitening mouthwash for short durations – a maximum of two weeks – and then take a short break from use to allow the pellicle an chance to catch up and repair. Doing so will allow your teeth to stay healthy and strong, while still giving you the benefits of a whitening mouthwash to give you a beautiful, healthy-looking smile.
