Whiten teeth: Toothpaste will not whiten teeth. Home remedies will not whiten teeth and may end up damaging the enamal leading to increased staining. The most effective way to whiten teeth is using the methods recommended by your dentist.

Let’s start here: lemons are acidic. Why are they acidic? They contain citric acid, about 5% by weight. Citric acid has the chemical formula C6H8O7, and the catchy systematic name of 2-hydroxypropane-1,2,3-tricarboxylic acid. If you look at the molecule you can see why it’s an acid. See those OH’s that are sitting next to =O’s? Those are acid groups. There are three of them. This is most definitel

NOT ADVISED!: Lemon juice is highly acidic and may make your teeth sensitive!! There is NO effective 'natural way' to bleach your teeth. You must invest in a Doctors whitening regimen or try Crest Whitestrips (available OTC at pharmacies). good luck!

Lemon = Acid: Acid = demineralization. Why try to reinvent the wheel? If your concoction were effective, there would be no need for professional and OTC whitening products, right? Follow the advise of your dentist to whiten your teeth safely and effectively.

Dr Davantzis is correct. Your home remedy WOLL do damage. Please see your Dentist for advice.
