Why Are My Teeth Sensitive to Sugar? | Eddie G Tennison DDS

If you’ve ever experienced the unpleasant and painful feeling of having sensitive teeth, you know how inconvenient it can be. Your dentist is the best person to ask if your teeth are sensitive to sugar and, if so, why.

While there are several potential explanations as to why your teeth may be sensitive to sugar, it’s important to note that an appointment with your dentist is key to discovering the root of the problem. Read on to learn more about this annoying condition and how to deal with it.

What Is Sugar Sensitivity?

When your teeth are sensitive to sugar, they’re prone to decay; tooth enamel is reduced, and teeth become discolored. Even though many different chemicals can cause these things, teeth sensitive to sugar usually react when glucose is present.

Sugar sensitivity is when teeth become more easily damaged by sugar. Since sugar can cause cavities, it will wear down the enamel on your teeth and cause discoloration.

To prevent tooth damage from sugar, people can use fluoride toothpaste, drink through a straw, and lower their intake overall.

Why Are My Teeth Sensitive?

This is a question you should ask your dentist if you think you have sugar sensitivity. There are several reasons why your teeth may react to sugar, including:

Gum disease

You're more susceptible to tooth sensitivity if your gums are inflamed or receding.


It could lead to sensitivity if you’ve sustained trauma during your lifetime, like a sports injury.

The Dangers of Sugar on Your Teeth

While sugar may be a delicious treat that most of us enjoy regularly, it can do irreversible damage to your teeth. Sugar is one of the leading causes of tooth decay, and it can also cause a shift in the chemicals in your saliva that can lead to tooth sensitivity.

If left untreated, sensitivity to sugar can lead to tooth damage. It's essential to be aware of these harmful effects and do what you can to avoid them.

How Can I Know If My Teeth Are Sugar Sensitive?

Your dentist may use a particular device to test for tooth sensitivity, but you can also try an at-home test. Place a small amount of sugar or another sweetener on your toothbrush and gently brush your teeth.

When the sweetener is removed, look for signs of tooth sensitivity, like pain or irritation in the gums. If your teeth are sensitive to sugar, you may experience a reaction that feels like a tingling or sharp pain in your gums.

You may also notice a slight drop in your salivary flow, leading to a tacky sensation in your mouth. If you notice any of these signs, your teeth are likely sensitive to sugar.

Tooth Decay Is One Reason For Sugar Sensitivity

If tooth decay has weakened the teeth, they may be more susceptible to a reaction when exposed to sugar. To avoid tooth decay, it’s essential to brush your teeth twice daily using a soft-bristled toothbrush and fluoride toothpaste.

It’s also important to floss at least once a day, as this can help remove food particles and bacteria that can cause tooth decay. Limit your intake of drinks and foods that are high in sugar, like soda, baked goods, and candy, as this can cause tooth decay over time.

Other Reasons For Tooth Sensitivity

If your teeth are sensitive to sugar, they may also be sensitive to cold, hot, or acidic foods or beverages. Gum disease or cracked teeth may also cause tooth sensitivity. If your dentist finds no signs of tooth decay when examining your teeth, they’ll likely recommend treating the sensitive area with a protective sealant.

Other possible causes of tooth sensitivity include misalignment of the bite, an exposed root due to gum recession, or improperly-fitted or loose dental appliances, like a retainer or brace.

How To Get Rid of Sugar-Sensitive Teeth

There are a few ways you can decrease your tooth sensitivity. You can cut back on your sugar intake. Studies show that reducing sugar intake can reduce tooth sensitivity over time. However, this solution is only effective if you stick to it.

Reduce Sugar Intake

Studies show that reducing sugar intake can reduce tooth sensitivity over time. However, this solution is only effective if you stick to it. Once you start eating many sugary foods again, you’ll likely experience sensitivity around your tooth.

By changing your diet, you can decrease tooth sensitivity over time. You can also add calcium carbonate supplements to your diet. Calcium carbonate aids in remineralizing your teeth and can help reduce tooth sensitivity.

Use an Enzyme Disintegrant Brush

You can use a gentle enzyme-based toothpaste and mouthwash to eliminate the bacteria on your teeth and reduce the acidity that causes tooth sensitivity.

These products can reduce your tooth sensitivity and eliminate them over time. You can also use an enzyme-based dentifrice to polish your teeth gently and remove surface stains and bacteria.
