What You Will Need:
* Awareness of foods and drinks that weaken enamel
* Strengthening toothpaste
Step 1. First of all, you need know what foods and drinks can weaken tooth enamel. Citrus fruits and juices, coffee, wine, tea, soda, sports drinks, and anything acidic. You don't absolutely need to stay away from all of these things because citrus fruits and juices are healthy for you, and coffee is a must-have for most people.
Step 2. Wait 30 minutes after eating or drinking these foods, to brush your teeth. I always thought that it was best to brush right away to get these things off of your teeth, but I was wrong. You want to wait 30 minutes before brushing because your enamel is really weak for that time period and brushing it will weaken enamel even further. This is probably the worst time to brush.
Step 3. When you brush, use a toothpaste that strengthens your enamel. I use Colgate Total Enamel Strengthening, but Sensodyne has an enamel strengthening paste as well. I am sure there are other brands too. Also, only use a tooth whitener that is enamel safe. Enamel is one of those things that can never be brought back, so you need to protect what you have.
