Is there anything worse than craving a sweet treat, only to feel a sharp pain in your teeth when you take a bite? If your teeth hurt when you eat sugar, it could be a sign of tooth sensitivity, caused by issues such as cavities, enamel erosion, or gum recession. Fortunately, with proper oral care and guidance from your dentist, you can enjoy your favorite sweets without discomfort.
Sugar & Tooth Sensitivity Explained
How Sugar Causes Tooth Decay
One of the main reasons sugar may cause discomfort is its role in tooth decay. When sugar interacts with the bacteria in your mouth, it forms acid that attacks your enamel—the protective layer of your teeth. Over time, this acid can weaken your enamel, leading to cavities and heightened sensitivity.
Prevention Tips:
- Brush your teeth twice daily with fluoridated toothpaste.
- Floss daily to remove food particles that bacteria feed on.
- Visit your dentist regularly for check-ups and professional cleanings.
Enamel Erosion
Enamel erosion is another cause of tooth sensitivity. When your enamel wears down, the underlying dentin becomes exposed, which can trigger pain when you eat sugar. Common culprits of enamel erosion include:
- Acidic foods like citrus fruits and tomatoes.
- Sugary carbonated drinks.
- Improper oral hygiene habits.
Pro Tip:
Limit acidic foods and rinse your mouth with water after consuming them. Wait 30 minutes before brushing to allow your softened enamel to reharden.
Gum Recession & Sensitivity
If your gums are receding, they expose the roots of your teeth, which aren’t covered by enamel. This leaves them more vulnerable to discomfort from sugary foods or drinks. Gum disease, known as gingivitis or periodontitis, is a major cause of gum recession.
Prevent Receding Gums by:
- Brushing gently with a soft-bristled toothbrush.
- Regularly flossing to maintain healthy gums.
- Avoiding tobacco, which can worsen gum disease.

How to Manage Tooth Sensitivity
If sugary foods are causing discomfort, there are actionable solutions to protect and soothe sensitive teeth.
Identify the Cause
Start by scheduling a visit to your dentist. They can determine whether your sensitivity is caused by enamel erosion, cavities, or gum recession, and help you develop an oral health plan tailored to your needs.
Use a Desensitizing Toothpaste
Switch to a desensitizing toothpaste, which helps block the pathways to your nerves and reduce sensitivity over time. Ask your dentist for recommendations on the best brands to suit your condition.
Adjust Your Diet
Sugary and acidic foods contribute significantly to enamel erosion and sensitivity. Reduce your sugar intake and opt for tooth-friendly snacks like cheese, nuts, or crisp vegetables. Don’t forget to drink plenty of water to flush away food particles and bacteria.
Protect Your Tooth Enamel
- Use toothpaste with fluoride to strengthen your enamel.
- Consider fluoride treatments during your dental cleanings to rebuild and fortify your teeth.
- Avoid grinding your teeth, as this can wear down your enamel. If you grind at night, speak to your dentist about a custom nightguard.
Explore Dental Treatments
Professional treatments for tooth sensitivity include:
- Fluoride varnish application to strengthen enamel.
- Dental bonding to cover exposed areas.
- Crowns or inlays for severe damage.

Practice Good Oral Hygiene
Daily brushing and flossing are critical for preventing tooth decay and sensitivity. Use a soft-bristled toothbrush and avoid brushing with too much force to protect your enamel and gums.
Replace your toothbrush regularly—every three months or sooner if the bristles appear frayed.
Schedule Regular Dental Checkups
During a regular dental checkup, your dentist may conduct a comprehensive oral examination to assess your overall oral health. These examinations may include x rays, periodontal evaluations, and oral cancer screening. At Northwest Dental we also provide complimentary digital dental health and bite scans.
