Acid is the Culprit Soft drinks contain acids.

Acid pulls calcium out of the enamel, making the tooth soft to the touch. Acid dissolves tooth enamel, a process called “decalcification,” and can lead to cavities. Once enamel dissolves, it does not come back. The loss is permanent.

Acid + Sugar = Double Trouble!

Plaque is a sticky, colorless film made up of bacteria, food debris and saliva that constantly forms on your teeth. Plaque uses sugar and starches as food, and expels acid as a by-product, creating a stain on the surface of the tooth. If plaque is not removed regularly by brushing and flossing, the build-up can lead to decalcification, cavities, gum disease, and loss of the bone that holds teeth in place. Coupled with acid that is present in soft drinks, drinking liquids containing sugar doubles the risk to tooth enamel.


How Soft Drinks Affect Teeth with Braces

White marks like these on teeth are the result of decalcification
and are permanent. If you don’t remove the plaque that collects around brackets,
between teeth and under the gums, decalcification can be evident within
four months.

How Soft Drinks Affect Teeth While Wearing Aligners



Liquids seep into aligners when you take a drink, and the liquid is held

against the teeth until the aligner is removed. If the liquid contains acid, the prolonged

exposure accelerates damage to teeth. This can lead to extensive decay (pictured above, right)

and the need for expensive restorations that may need to be repeated

periodically over a lifetime.
