Raspberries, blueberries, pomegranates and other berries are packed full of antioxidants, but they also contain rich pigmented juices capable of staining your teeth. The effects are the same, whether you eat them fresh or in processed foods like jam, so follow up with an acid neutralizing treat, like a glass of milk or a bit of hard cheese.

Sugary Treats

There’s some truth to what Grandma always said -- sugar can rot your teeth. Bacteria in your mouth feed off sugar and, in the process, release acids that damage teeth and cause dark spots and other forms of decay.

I love this office. Dr. Harrison and his staff are awesome. Everyone there is kind and patient. They have really up to date technology and give plenty of reminders for appointments (which makes a busy mom very happy)

The same tannins that give tea and coffee their staining power are also found in wine! Wine, like your other favs, is also acidic and causes enamel erosion. Think white wine is better? Not so much – it’s still chock full of acid.


Citrus foods are highly acidic and break down enamel, exposing the dentin and increasing the risk of staining and yellowing. Even brushing after can be problematic -- your teeth may already be weakened from the acid, making brushing and flossing more damaging than helpful.

Arming yourself with the knowledge featured here is the first step to fending off stains and yellowing. Don’t worry though -- there’s no need to cut out all your favorite foods. Instead, eat and drink acidic, highly pigmented foods and drinks like these in moderation, use straws or a lid and don’t let them linger in your mouth for too long.
