Why Do My Teeth Hurt When I Eat Sweets?

Causes, Symptoms, Treatments

November 10, 2024 Written By: Joyce Kahng, DDS

Tooth sensitivity to sweets is something many people deal with, and it can be really uncomfortable. You might feel a mild twinge or even sharp pain when enjoying your favorite sugary treats.

Here’s why this happens:

  • Worn enamel: Tooth sensitivity often occurs when the protective enamel wears down, exposing the sensitive dentin and nerve endings underneath.
  • Sugar and bacteria interaction: When you eat sugary foods, the sugar interacts with bacteria in your mouth and creates acids, which can further irritate those sensitive areas.
  • Indication of dental issues: Sensitivity to sweets can sometimes signal other dental issues like cavities or gum disease.

4 Common Causes of Sensitivity to Sweets

Enamel Erosion

Enamel erosion is a major culprit behind tooth sensitivity. As time goes on, our protective enamel begins to wear away, exposing the sensitive dentin underneath. This layer is like a highway of tiny tubules that connect straight to the nerves in our teeth.

When the enamel gets thinner, sugary foods can easily slip through and cause discomfort. Erosion can happen due to several habits:

  • Frequently munching on acidic foods like citrus fruits
  • Sipping on sugary drinks
  • Grinding our teeth while sleeping

Gum Recession

Gum recession occurs when the gum tissue pulls back from the teeth, revealing more of the tooth or its root. This condition can lead to increased sensitivity to sugar, which can be quite uncomfortable.

It’s important to take gum recession seriously. Here are some tips for prevention:

  • Gentle brushing to avoid further irritation
  • Regular flossing to keep the gum line healthy

Tooth Decay and Cavities

Tooth decay and cavities can really take a toll on your oral health, causing sensitivity, especially when you enjoy your favorite sweet treats.

Cavities occur when acids from bacteria in your mouth eat away at your teeth, creating tiny holes. If the decay progresses deep enough, it can reach the nerves, leading to pain.

Indulging in sugary foods can make that pain worse, as sugars fuel bacterial growth and accelerate decay.

Cracked or Damaged Teeth

Cracks in your teeth might seem like a small issue, but they can actually cause quite a bit of discomfort and lead to bigger problems.

  • These tiny fractures can allow sugar and bacteria to sneak in, reaching the inner parts of your tooth. 
  • As they invade, they can cause heightened sensitivity and pain in areas like the dentin and pulp

If left unchecked, this can lead to serious dental issues such as:

  • Cavities
  • Infections
  • Tooth loss

Symptoms of Tooth Sensitivity to Sweets

If you’ve ever felt sharp or throbbing pain while enjoying your favorite sugary treats, you know how frustrating it can be. Sometimes, that discomfort sticks around even after you’ve finished eating.

The intensity of the pain can vary depending on what’s causing it. For example, if tooth decay is the issue, you might experience a constant ache from exposed nerves. On the flip side, gum recession could cause sudden bursts of pain when sugar touches the sensitive roots of your teeth.

Paying attention to how and when you feel this pain can give you valuable insights into what might be going on.

Why Sugar Makes Sensitive Teeth Hurt More

If you have sensitive teeth, you might notice that sugar makes things worse. Sugar particles can sneak into tiny openings in your enamel and irritate the sensitive dentin or nerves underneath. This can lead to sharp pain, especially if your enamel is worn down or your gums are receding. 

When you enjoy sweets, it can really ramp up that sensitivity as the sugars bypass your teeth’s defenses and irritate the sensitive areas. 

When to Consult a Dentist

Understanding when to seek help from a dental professional is key to keeping your smile bright.

Regular check-ups not only offer peace of mind but also help catch potential issues before they require more serious treatment. If you find yourself frequently sensitive to sweets or if it’s getting worse, don’t hesitate to book a dental appointment.

Home Remedies and Self-Care for Mild Sensitivity

Using Desensitizing Toothpaste

Desensitizing toothpaste is a game-changer for those with sensitive teeth. This specialized toothpaste contains compounds that block pain signals from reaching the nerves, providing noticeable relief.

To maximize its benefits, here are some tips:

  • Use a soft-bristled toothbrush to gently apply the toothpaste, minimizing further enamel wear.
  • Don’t rinse immediately after brushing; this allows the active ingredients to fully absorb and work effectively.

For the best results, use the toothpaste consistently to maintain comfort and health in your smile.

Good Oral Hygiene Practices

Maintaining stellar oral hygiene is crucial for managing sensitivity and enhancing your dental health. Here’s how you can keep your smile healthy and strong:

  • Brush twice daily with a soft-bristled brush, using gentle strokes to prevent gum damage.
  • Floss daily to remove plaque and food particles from between your teeth. This minimizes bacterial growth and decay.
  • Consider incorporating a fluoride rinse into your routine. It strengthens enamel, reduces sensitivity, and provides extra protection against acid attacks.

Avoiding Sugary and Acidic Foods

Limiting your intake of certain foods can significantly impact your level of tooth sensitivity. Sugary and acidic foods are notorious for weakening enamel and increasing discomfort. To safeguard your teeth, consider the following:

  • Cut down on sweets and sodas. These contribute to enamel erosion and sensitivity. 
  • Be mindful of acidic fruits like citrus. Their high acid content can wear down your enamel over time. 
  • When consuming these items, try to rinse your mouth with water afterward. This helps neutralize acids and wash away sugars.

In-Office Treatments for Persistent Sensitivity

Fluoride Treatments

Fluoride treatments are a great way to protect your enamel and help prevent sensitivity. When you visit the dentist, they might apply a fluoride varnish directly to your teeth.

This quick and painless process involves:

  • Painting a concentrated fluoride solution on your teeth
  • Strengthening your enamel fast
  • Providing lasting relief

Not only does it boost your enamel’s resilience, but it also helps remineralize areas where decay is starting, keeping discomfort at bay.

Dental Bonding or Sealants

Dental bonding or sealants serve as a protective shield over exposed dentin, helping to ease sensitivity to sweets and other irritants. Imagine it as putting a cozy blanket over the sensitive spots on your teeth.

This treatment restores the joy of eating your favorite snacks. You can indulge in treats without the fear of discomfort.

Treatment for Gum Recession

Gum recession can make teeth highly sensitive to sweets by exposing their roots. This can be uncomfortable and affect your enjoyment of various foods.

A common solution is gum grafting. This procedure covers the exposed roots and protects them from sensitivity.

  • Tissue is taken from the roof of your mouth or a donor source.
  • This tissue is then grafted onto the affected area.
  • Not only does this reduce sensitivity, but it also improves the appearance of your gums.

Cavity Treatment or Filling Repairs

Taking care of tooth decay is super important to avoid more damage and lessen the pain that comes with sweets.

When cavities develop, they leave openings that allow sugar in and irritate the nerves in your teeth. By tackling decay early, you can enjoy your favorite sugary treats without discomfort.

Filling cavities with strong materials like composites or amalgams helps restore the tooth’s strength, keeping nerves protected and reducing sensitivity.
