There are many ways to whiten teeth, but some everyday actions inadvertently cause teeth to become yellow.
Drink carbonated water
Quitting soda and carbonated drinks is the right decision that your teeth will silently thank you for. The carbonic acid in carbonated water cannot seriously damage tooth enamel, but if there are additional flavoring additives, it will affect the acid concentration, increasing the likelihood of enamel erosion.
Use soy sauce often
There’s no denying the deliciousness of soy sauce makes sushi so appealing, but they are the cause of teeth yellowing over time.
Just like other colored foods, soy sauce stains teeth and makes whitening toothpaste less effective.
Frequent use of hot drinks
Nothing wakes the body up in the morning faster than a hot cup of coffee. But if used every day, they will promote the yellowing process of tooth enamel. Even, the habit of drinking hot to keep the body warm on a cold day also increases the small cracks on the enamel, making the teeth more sensitive.
Remember, coffee, tea and pigment-rich beverages can stain teeth, especially when consumed hot.
Using the wrong mouthwash
Mouthwash keeps your breath fresher for longer, but also makes your smile less bright, if you don’t pay attention to the ingredients inside. For example, mouthwashes that are specially formulated to treat gums often contain chlorhexidine gluconate, which can cause stains on your teeth that are difficult to remove without your dentist’s help.
Using a brush that is too strong
Brushing and flossing are ways to keep your smile bright, but oral hygiene isn’t always better. Brushing too hard for days can wear down enamel, making teeth more sensitive and increasing the risk of tooth decay.
Not drinking enough water
Drinking enough water is one of the best things for overall health and a bright smile. In particular, water helps wash away residual stains and keep teeth whiter for longer.
