Board Certified DentistYes, it's generally safe for most people. You probably shouldn't use them if you have braces, though. You'll also want to avoid using them if you've had restorative work down, like a crown, filling, or veneer. -

Board Certified DentistIt kind of depends on a couple of factors. If your teeth are yellow, it's because the dentin underneath your enamel is showing through. If your enamel has been worn away, there isn't really a whole lot you can do to get the enamel back. However, you may be able to get your teeth a few shades whiter by brushing regularly, flossing, and seeing your dentist for regular cleanings. Teeth whitening strips can also help, but you shouldn't use these if you have braces or if you've had any restorative work done. -

A good final result requires not just brushing with baking soda but also a balanced diet. You can see good improvements after the first two weeks, but if you are not happy with the result then you should go for a professional whitening treatment

Tips
-
Drinks like coffee, tea, and wine can all stain your teeth, so be sure to cut them back or brush your teeth after having them.[16]Thanks
-
At-home whitening treatments will only work on natural teeth, so they won’t be effective if you have crowns or veneers.[17]Thanks
-
Try to quit using tobacco products you use since they can discolor and stain your teeth.[18]Thanks
Tips from our Readers
- Get several teaspoons of baking soda and mix with enough lemon juice to make paste. Brush it on with a toothbrush and leave on for a minute, then don't eat for a few hours afterwards. This is best done before bed.
- Try oil pulling, which is an old Indian trick from a long time ago. Take a tablespoon of coconut oil and swish it in your mouth for 5 minutes (or 10 for best results). Rinse afterwards.
- Help keep the teeth white by drinking liquids that can darken your teeth from a straw, but don't drink hot liquids through a straw.
Warnings
- Any tooth-whitening method might cause increased sensitivity.[19]Thanks
- Fruits like strawberries, oranges, and lemons are all acidic and can cause your enamel to wear away.[20]Thanks
- Avoid using activated charcoal to whiten your teeth since it’s abrasive and could wear away at your enamel.[21]Thanks
- Over-the-counter hydrogen peroxide isn’t an effective tooth whitener, and it could cause pain or inflammation to your gums.[22]Thanks
