3 Habits That Can Strengthen Tooth Enamel

Tooth enamel is the hardest substance in the human body, yet the tiny bacteria living in our mouths can produce acids, which cause it to erode. Maintaining good oral hygiene can help prevent bacteria from creating cavities. Developing these three habits can actually strengthen your teeth and strengthen enamel over time, and prevent enamel erosion.

Drink Fluoridated Water

Fluoride is a naturally occurring mineral that is always present, to a small degree, in water, but many cities and companies also add fluoride to the water supply. Years of research have proven that drinking fluoridated water can reduce your risk of cavities by 20 to 40 percent.

Fluoride helps to strengthen enamel in a few ways. First, when fluoride in the water makes contact with your teeth, some of it is incorporated into the surface of your teeth. This makes them less vulnerable to decay.

Next, after your body ingests the fluoride, it will be present in your saliva, which is always in contact with enamel. Thus, you are giving the fluoride a second chance to absorb into the enamel, and make your teeth more decay-resistant.

Additionally, if you choose water over soda or juice, you are eliminating one common source of sugars that can contribute to tooth decay.

Chew Sugar-Free Gum

Chewing sugar-free gum when you can’t brush will help to stimulate the production of saliva which is good for your teeth. Not only does your saliva help wash away the acids that cause cavities, but also the mineral content of your saliva can help remineralize and strengthen your tooth enamel.

Brush With Enamel-Hardening Toothpaste


When choosing toothpaste, selecting fluoride toothpaste will ensure that you are protecting and hardening your enamel while you clean your teeth. Many toothpastes, such as Colgate® Sensitive Prevent & Repair, are specially formulated to help strengthen tooth enamel. Getting in the habit of brushing at least twice a day will help keep your enamel strong and healthy.
