Lemon
Lemon is a good source of citric and ascorbic acid, responsible for its sour taste. As a result, it has various health benefits, such as weight control, good digestion, and normal blood pressure. Lemon juice is also good for oral health; it can neutralize foul odors and solve teeth discoloration.
There are two ways to use lemon to whiten teeth. First, rub the lemon peel on the teeth after brushing and wait 4 to 5 minutes before gargling with clean water. This method is proven effective in removing coffee stains in the teeth. Another way is diluting freshly squeezed lemon with water and using the solution as a mouthwash. This is an effective way to reach the cracks and crevices of the teeth.
However, according to a study, lemon contains acid that could cause tooth decay or worsen your teeth’s condition. It might destroy enamel and soon wreck the calcium in your teeth. So, experts advised patients to limit this method to once a week.
