Avoid Coffee
We know that coffee isn’t easy to give up, but during a whitening routine it is crucial that you stay away from the dark beverage, as it’ll stain your teeth. You might want to also avoid black tea, mustard, ketchup and hot chocolate.

Avoid smoking
Smoking is probably the worst possible thing you could do to your teeth. Tobacco causes brown stains that penetrate the tooth enamel. The longer you smoke, the deeper your stains will become. The best way to get a whiter smile is to quit smoking altogether.

Eat plenty of carrots, Cauliflower and apples
The crunchy (and healthy) snacks will get you chewing and will therefore get your saliva flowing, which will neutralize the enzymes and acids that threaten your enamel.

 
Rinse with water after eating citrus fruits
Try to rinse your mouth out with water every time you eat oranges, lemons or limes. Citrus fruits are very acidic and can damage tooth enamel. By washing out your mouth, you’ll get rid of the destructive acid.

 
Rinse with apple cider vinegar
In a glass, mix two parts water and one part apple cider vinegar. Stir it well and rinse your mouth out for around one minute. This whitening solution is natural and organic.

 
Sprinkle some baking soda on your toothpaste
Baking soda –also known as Sodium bicarbonate– is a powder that has the ability to return teeth to a whiter shade. Sprinkle some over your toothpaste once a week for a nice result. Don’t overdo it though, as it can become damaging.

 
Floss and brush regularly
These go without saying, but don’t forget to brush at least twice a day and floss daily. Taking good care of your teeth is the best way to keep them white and healthy.
