Why Are My Teeth Sensitive To Sugar?

Pasted image 0

Many people report having sensitive teeth from time to time. What does this mean, and why does it happen? Sensitive tooth is a condition in which your teeth become painfully sensitive to hot, cold, sweet, or sour foods.

Having sensitive teeth can make eating certain foods very uncomfortable, but the pain usually lasts for a brief period before going away again. Most of the time, sensitive teeth are caused by roots that are showing due to gingivitis or other forms of decay that has caused the gums to pull away from the roots of the teeth.

When this happens, you’re more susceptible to bacterial infections that can cause a painful response from your sensitive teeth once you eat something sugary or acidic. Yet there are additional reasons you might experience this sensitivity, which we’ll explore in this article and tell you how Smile Line Dentistry can help you.

What Are The Symptoms Of Sensitive Teeth?

If you have sensitive teeth, you will likely notice at least one of the following symptoms:

  • When you eat or drink something cold, hot, or sweet, your teeth ache or throb.
  • Sharp pain in your teeth when you brush or floss.
  • Increased tooth sensitivity when eating cold foods like ice cream, soda, or iced drinks.
  • Increased tooth sensitivity when eating sweet foods like candy, sugary baked goods, or fruit.
  • Increased tooth sensitivity when eating acidic foods like orange juice, tomatoes, or vinegar.

Sugary Food And Tooth Decay

Sugar is a common cause of tooth decay that can lead to gingivitis and receding gums, which can, in turn, cause sensitive teeth. When sugar is present in your mouth and bacteria feed on it, they create acids that can dissolve tooth enamel, causing cavities and gingivitis.

Gingivitis is a bacterial infection of your gum tissue, which can cause your gums to become inflamed and recede from your teeth. Once the bacteria have reached this stage, they’re much more likely to enter the bloodstream, which can produce a painful response in your sensitive teeth if you eat something sugary or acidic.

If left untreated, gingivitis can progress to periodontitis. It is an infection of the tissues around your teeth. If this happens, your dentist may suggest taking out your gums surgically to stop the bacteria from spreading.

Excessive Brushing And Receding Gums

Excessive brushing can cause your gums to recede from the root of your teeth, exposing them and making them more sensitive. If you have sensitive teeth, brushing them too vigorously can cause pain and irritation.

Excessive brushing can also cause your gums to recede in the area of your teeth between the gum line and the tooth’s root.

Healthy gums are positioned between the tooth’s root and surface. Excessive brushing can cause your gums to shrink and pull away from your teeth, exposing the roots of your teeth and making them more sensitive to foreign particles.

Calcified Tissue Buildup In Your Teeth

Calcified tissue buildup in your teeth can also cause sensitivity. This happens when you don’t have enough calcium in your diet, which can lead to the growth of a hard deposit around the gums.

When the buildup is not removed, it can cause the gums to pull away from the teeth exposing the vulnerable parts to more damage and sensitivity.

A particular type of toothpaste containing an enzyme can help break down the buildup around the teeth.

Root Resorption Due To Dental Decay

Root resorption occurs when dental decay eats away at the tooth’s root. This can cause the tooth to become loose or even fall out.

If this happens, the sensitive nerves in your gums will be exposed. These exposed nerves are much more likely to become inflamed or painful when you eat something sweet or acidic.

Other Causes of Tooth Sensitivity


Some people are just born with teeth that are more sensitive than others. If your parents have sensitive teeth, there’s a higher chance that you will too. Genetics can also play a role in staining and gum disease.

Gum disease can make your teeth more sensitive, so staying on top of your oral hygiene is essential. You can lessen the effects of your genes by taking care of your teeth and going to the dentist regularly.

Aging of Your Teeth

As you age, your teeth naturally become less porous, making them more likely to become sensitive. It’s normal for teeth to become more sensitive as you age, but excessive dental cleaning products, such as whitening products, can contribute to higher sensitivity.

Limiting the number of whitening products you use can help reduce the aging of your teeth.

Treatment for Sensitive Teeth

Tooth sensitivity is a common condition that affects as many as two in five people. It is caused by either tooth decay or gum disease, making it painful or difficult to eat certain foods. It can also lead to bad breath, and teeth are more likely to break easily.

If you’ve been experiencing tooth sensitivity, you must visit your dentist to find out what’s causing the issue. Your dentist will look for signs of tooth decay and gum disease by giving your mouth a thorough checkup.

If the dentist notices that your gums have receded or that you have signs of gum disease, they will likely recommend that you have your teeth cleaned by a dental hygienist.

The hygienist might also take a small tissue sample from your gums so the dentist can examine it for signs of infection. When the infection and inflammation have been treated, your sensitive teeth will surely return to normal.

At that point, your dentist can also help you maintain healthy gums so that you don’t have to deal with this problem again.
