Can Sugary Drinks Cause Cavities and Enamel Damage?

Your favorite soda, tea, or energy drink may be affecting your teeth more than you realize. This article explains how everyday beverage choices increase the risk of enamel damage and cavities and how to protect your smile.

The Sugar and Cavity Connection

Our mouth naturally contains bacteria, some of which are harmless, while others feed on the sugars left behind after you eat or drink. When these bad bacteria consume sugar, they produce acid, which attacks and breaks down the enamel protecting your teeth. Saliva helps neutralize the acid, but frequent sipping does not give your mouth much time to recover. Over time, the tooth enamel weakens. A small soft spot often forms and eventually turns into a cavity.

Soda is not the only drink that causes this problem. Sweet tea, sports drinks, energy drinks, lemonade, flavored coffee, fruit punch, and juice may all contain enough sugar to feed cavity-causing bacteria.

Are Sugar-Free Drinks Better for Your Teeth?

Even sugar-free soda can harm your teeth. Most sodas on the market today contain acids that give them their tart or tangy flavor. These acids wear down enamel without any help from cavity-causing bacteria. This process is called dental erosion.

As enamel thins, teeth can look more yellow, develop rough edges, or become sensitive to cold drinks and sweets. This means switching from regular soda with sugar to diet soda without sugar does not fully prevent enamel damage from acids.

Sipping All Day Causes More Damage

How you drink sugary or acidic beverages matters almost as much as what you drink. Perhaps you enjoy a soda during your lunch break at work while a co-worker opens the same size and type of soda and sips it all day. Both of you consumed the same amount; however, your teeth experienced something very different.

Drinking a soda all at once exposes your teeth to sugar and acid for a short time, while sipping it all day repeatedly exposes your teeth to the same sugar and acid for hours. Your mouth needs time between meals and drinks to clear away acids. Constant sipping keeps that from happening, which increases the risk of damage.

This same principle applies to the following drinks:

  • Large fountain drinks
  • Sweetened coffee
  • Sports and energy drinks
  • Sweet tea
  • Juice in children’s cups

Being aware of how you drink sugary or acidic beverages is a good start to reducing your cavity risk.

Are Sports and Energy Drinks Better for Dental Health?

Sports drinks often sound healthier than soda, but most contain both sugar and acid, just like soda. Plain water usually provides all the hydration you need during strenuous exercise.

Energy drinks are even worse. They usually contain much more sugar and double the acidity of sports drinks.

Perhaps you don’t drink soda, sports, or energy drinks. Beware! Sweet tea, lemonade, fruit drinks, and some flavored waters are not much better and damage enamel over time.

Whatever you choose to drink, make sure you check the label and don’t be fooled into thinking that “sugar-free” is better because the acid level probably isn’t.

Early Signs of Enamel Damage

Damage to your enamel in the early stages does not always cause pain; in fact, you often will not notice anything until the problem becomes more advanced.

Be aware of the following warning signs that your enamel needs some help:

  • Sensitivity to cold or sweet foods
  • Teeth that are beginning to turn yellow
  • Rough or uneven edges of a tooth
  • Small chips in a tooth
  • Pain when biting or chewing
  • Visible dark spots or holes in a tooth
  • Consistent tooth pain

Enamel, although the hardest substance in the human body, is not indestructible. And once the damage is done, it doesn’t grow back or repair itself. A professional dentist helps protect the remaining tooth structure, but preventing enamel damage is much easier than repairing it.

What is The Solution?

Giving up soda, sports drinks, energy drinks, and other beverages high in sugar and/or acid can reduce enamel damage, but that’s not realistic for everyone. A few intentional changes, however, make a noticeable difference.

Drink It With a Meal

If you plan to have a beverage high in sugar or acid, enjoy it with lunch or dinner instead of sipping it on its own. Your mouth naturally produces more saliva while you eat, which helps rinse away sugar and reduce acidity.

Finish It Within a Reasonable Time

Try not to stretch one drink across several hours. Every sip starts another acid attack.

Follow It With Water

Rinse your mouth with plain water after drinking soda, sweet tea, juice, or an energy drink. Water helps wash away some of the sugar and acid left behind.

Use a Straw

A straw placed toward the back of your mouth rather than directly behind your teeth reduces how much sugar and acid wash across the front of your teeth. Of course, a straw doesn’t prevent all contact with your teeth, but it certainly helps.

Don’t Brush Right Away

Acid temporarily softens the enamel surface, so brushing right away after an acidic drink causes more wear. Instead, rinse with water, and then wait 30 to 60 minutes before brushing.

Chew Sugar-Free Gum

Sugar-free gum increases saliva flow, which helps clear acids from the mouth. Gum containing xylitol is a good choice when you can’t brush.

Choose Water More Often

Water does not need to become your only drink, but it should be the one you reach for most often. Save soda and other sugary or acidic drinks for an occasional treat rather than an all-day source of hydration.

When to Call an Emergency Dentist

Changing your drinking habits helps protect your enamel from further damage, but it will not fix a cavity that has already formed. Ongoing tooth pain, sensitivity, or swelling usually means something more serious is going on and should be checked before it gets worse.
