3. Watch What You Consume
One of the most affordable ways to whiten your teeth naturally at home is by protecting them from stains in the first place! Watch what you eat and drink, and enjoy your pearly whites looking beautiful for longer.
Beverages you may like to avoid are soda, red wine, and coffee, while you may also wish to stay away from berries and tomatoes as well. If you intend on taking stain prevention one step further by brushing and flossing post-meal, wait at least 30 minutes to protect your enamel.
