Why Do My Teeth Hurt When I Eat Sweets?

Do your teeth hurt when sipping a cold drink or biting into a piece of candy? Tooth sensitivity is often associated with hot or cold temperatures, but eating sweets can also trigger pain for many people. This discomfort can stem from several underlying issues that compromise your dental health.

If you're experiencing tooth sensitivity or pain after eating sugary foods, you might be wondering why sugar hurts your teeth. There are several reasons why this happens, and understanding them can help you find relief and protect your oral health.

What is Tooth Sensitivity?

Tooth sensitivity occurs when the dentin, the layer of tissue beneath the enamel or the hard outer layer of teeth, becomes exposed from enamel loss. The dentin contains tiny tubules that lead to the nerve fibres within the tooth. When these tubules are exposed, changes in temperature or acidic substances can irritate the nerves, causing sensitivity.

Enamel loss can be caused by cavities from plaque buildup and aggressive brushing. Additionally, conditions like acid reflux, which brings stomach acid into contact with teeth, can accelerate the breakdown of enamel, exacerbating sensitivity and increasing the risk of dental issues.

Why Do Sweets Hurt My Teeth?

Sugar itself doesn't actually directly harm your teeth. Instead, it interacts with bacteria in your mouth, creating acids that erode enamel. 

Over time, this process can expose the dentin and lead to cavities that increase sensitivity. Teeth may also feel more sensitive to sugar after a thorough cleaning as the removal of plaque and tartar temporarily exposes areas of the tooth that were previously shielded.

Why is My Tooth Suddenly Sensitive to Sugar?

Several factors can contribute to increased sensitivity to sugar:

1. Enamel Loss: The Protective Barrier Breaks Down

Acidic by-products from sugar-consuming bacteria soften and wear away the enamel. Although saliva helps dilute these acids and even aids in the remineralisation of dental enamel, frequent snacking can hinder this process as it can expose your teeth to sugar and acids at frequencies that cannot be countered naturally.

2. Tooth Decay (Cavities): The Bacterial Invasion

Plaque bacteria feed on sugars, producing acids that erode enamel and lead to cavities. As cavities grow, they expose the dentin, causing pain when exposed to sugary substances.

3. Gingivitis (Gum Disease): The Inflammatory Response

Plaque and tartar buildup can cause gingivitis, an inflammation of the gums. This condition can lead to root exposure, making teeth more sensitive to sugar.

4. Receding Gums: The Root Exposure

Receding gums expose tooth roots, which lack the protective enamel layer. Common causes include ageing, smoking, aggressive brushing, and poor oral hygiene.

5. Tooth-Whitening Treatments: The Sensitivity Side Effect

Some whitening treatments temporarily increase sensitivity by allowing whitening agents to penetrate the dentine, amplifying reactions to sugar. Therefore, it's important to be aware of this potential side effect and discuss it with your dentist before using any over-the-counter whitening products, especially if you already have sensitive teeth.

How Does Sugar Sensitivity Feel?

Sugar sensitivity can manifest in different ways, and what you may experience might differ from someone else's.

Some of the common ways sugar sensitivity can make itself known include:

• Sharp, Shooting Pain: This is often the most common and instantly recognisable sensation. It's that sudden, intense jolt of pain that seems to shoot through your tooth when it comes into contact with something sweet. This type of pain is usually short-lived but can be quite jarring.
• Aching Pain: Unlike the sharp, fleeting pain described above, aching pain tends to be more constant and dull. It might linger for a while after you've finished your sweet treat, leaving a persistent discomfort in the affected tooth or teeth.
• Tingling: Some people experience a tingling sensation rather than outright pain. While not as intense as sharp pain, it can still be an uncomfortable and distracting sensation.
• Referred Pain: In some instances, the pain can radiate to other areas, such as your sinuses, eyes, or face. This can make it tricky to figure out where the problem is coming from, but it's worth considering that it might stem from your teeth.

Remedies for Sensitive Teeth

If you find your teeth hurting when eating sweets, rest assured that there are treatments available to help manage and even overcome your sensitivity. 

Consider these options:

• Desensitising Toothpaste: This is often the first line of defence to combat sensitive teeth, as they are specially made to block the microscopic tubules in your dentine, preventing external triggers from reaching the nerves and causing pain. You can check out an option like the Optimal A.R.T. Active Remineralization Toothpaste made with Hydroxyapatite, which can help repair demineralised tooth enamel. Meanwhile, other options are toothpaste made with Potassium Nitrate, which can numb the teeth’s nerves to make them less responsive to external stimuli like hot, cold, or sweet foods, helping relieve tooth sensitivity. Some of these options include the Advanced Sensitive Fluoride Toothpaste and All Natural Sensitive Toothpaste, as they are both formulated with Potassium Nitrate and Xylitol, which can strengthen tooth enamel. 
• Remineralising Toothpaste: For sensitivity linked to weakened or demineralised tooth enamel, consider using a remineralising toothpaste, such as the Optimal A.R.T. Active Remineralization Toothpaste. This toothpaste contains Hydroxyapatite, where Hydroxyapatite particles can block the open dentinal tubules. These tubules are tiny channels that lead to the nerves inside the tooth. When they are exposed, stimuli like hot, cold, or sweet foods can reach the nerves, causing pain. By blocking these tubules, hydroxyapatite prevents these stimuli from reaching the nerve.
• Choose a Soft-Bristled Toothbrush: Opt for a soft-bristled toothbrush with a compact head to effectively reach all areas of your mouth and gently remove plaque without causing damage to your gums or enamel. Options like the BrushCare Professional Sensitive Extra Soft Toothbrush or BrushCare Sensitive Extra Soft Toothbrush have compact heads while also having handles with non-slip grips for better control and to prevent excessive pressure while brushing.
• Gentle Flossing: Opt for a gentle flossing method to remove plaque and debris without aggravating your sensitivity. Consider using floss designed for sensitive teeth, like the FlossCare Plus PTFE Mint Floss, which glides smoothly between teeth to minimise irritation and can help eliminate bacteria between teeth and gums. Alternatively, try the Portable Water Flosser, which is a compact and cordless option that uses water jets to help clean between teeth and remove plaque in hard-to-reach areas. Plus, this floss has three cleaning modes to accommodate different cleaning needs, which are gentle for sensitive teeth and first-time users, pulse for daily cleaning and gum massage, and strong for deep cleaning.
• Fluoride Varnish: This treatment provides a concentrated dose of Fluoride, which helps to strengthen enamel and reduce sugar sensitivity.
• Dental Restorations: If damaged teeth, such as chips, cracks, or cavities, cause sensitivity, your dentist might recommend dental restorations like crowns, inlays, and composite fillings that can repair damaged teeth.
• Surgical Gum Grafts: In cases where gum recession has exposed the roots of your teeth, surgical gum grafts can be a solution to cover the exposed roots and reduce sensitivity.
• Root Canals: If your sensitivity is caused by severe decay that has reached the teeth's pulp, a root canal might be necessary to remove the infected pulp and seal the tooth to prevent further infection and pain.

How Mouthwash Can Help Soothe Sensitive Teeth

Incorporating mouthwash into your oral care routine offers two key benefits for sensitive teeth:

Two Mechanisms of Action

Mouthwashes for sensitive teeth like the Sensirinze™ Fluoride Mouth Rinse for Sensitive Teeth often work in two ways. Firstly, they utilise nerve-desensitising ingredients like Potassium Citrate and Potassium Nitrate, which can block the nerve signals responsible for transmitting pain sensations, therefore reducing sensitivity. 

Secondly, the presence of enamel-strengthening compounds such as Fluoride and Xylitol reinforce the enamel, making it more resistant to acid attacks and erosion and ultimately helping to prevent future sensitivity.

Key Desensitising Ingredients

These ingredients work together to help alleviate sensitivity and promote stronger, healthier teeth:

• Potassium Nitrate: This compound works by blocking the tubules in the dentine, preventing nerve stimulation and providing relief from sensitivity.
• Sodium Fluoride: It strengthens the enamel, making it more resistant to acid attacks that cause sensitivity and cavities.
• Calcium Phosphate: A natural component of tooth enamel, this mineral replenishes calcium and phosphate in enamel, promoting remineralisation and reducing sensitivity.

Mouthwash vs. Toothpaste: A Complementary Approach

While mouthwash and toothpaste can reduce sensitivity when used alone, using them together creates a synergistic effect that maximises your protection from multiple angles. 

For instance, Pearlie White's Sensitivity Relief range offers a comprehensive approach to managing sensitive teeth. With specially formulated toothpaste that cleans and desensitises and mouthwash that provides ongoing protection and relief throughout the day, managing oral health is a breeze.

Tips for Using Mouthwash for Sensitive Teeth

To get the most out of your mouthwash and maximise its effectiveness in combating sensitivity, consider these tips:

Choose Alcohol-Free Mouthwash With Fluoride

Alcohol can be irritating to sensitive teeth and gums and can exacerbate dryness, a contributing factor to sensitivity. As such, opt for an alcohol-free formula with Fluoride like the Sensirinze™ Fluoride Mouth Rinse for Sensitive Teeth and Fluorinze Anti-bacterial Fluoride Mouth Rinse, which is gentle on teeth and gums while providing protection.

Use The Correct Amount And Swish For The Recommended Time

Pay close attention to the directions on your mouthwash bottle, as using too much or too little can impact its ability to clean and protect your teeth and gums. To ensure you're using the optimal amount, fill the cap up to the halfway mark with undiluted mouthwash. Then, swish the mouthwash around your mouth for 30 seconds to a minute to ensure it reaches all areas and has sufficient contact time to work its magic. Also, it’s important to note that mouthwash is not recommended for children under six years of age. For children aged six and above, use mouthwash only under adult supervision to ensure they do not swallow the rinse.

Avoid Using Mouthwash Immediately After Brushing

To maximise the benefits of your toothpaste, especially those containing Fluoride and other enamel-strengthening ingredients, it's important to allow some time for these ingredients to interact with your teeth. This means not immediately rinsing your mouth after brushing, giving the beneficial components a chance to work their magic and protect your enamel. Instead, it's best to wait at least 20 minutes before using mouthwash.

Use Mouthwash at Other Times Of The Day For Added Protection

Rinsing with mouthwash after meals or snacks can help neutralise acids and provide extra protection against sensitivity throughout the day. For those who are always outside, consider bringing a travel-sized mouthwash like Fluorinze Anti-bacterial Fluoride Mouth Rinse, making it easy to maintain your oral care routine wherever you go. This mouthwash is formulated with Tea Tree Oil and Thymol to help fight tooth decay and prevent bad breath, along with Cetylpyridinium Chloride and Xylitol to fight bacteria and germs that cause bad breath, plaque and cavities.

Other Ways to Soothe and Prevent Sugar Sensitivity

Beyond mouthwash and toothpaste, there are other ways to manage and prevent the discomfort of sugar sensitivity. Here's a closer look at some key lifestyle changes and preventative measures:

• Limit Sugar Intake: Reduce sugary foods and drinks like snacks, fizzy drinks, and hard candies to minimise acid attacks on your teeth.
• Practice Good Oral Hygiene: Brush your teeth twice a day with Fluoride toothpaste and daily flossing to maintain optimal oral health.
• Consider Dental Sealants: Dental sealants act as a barrier to prevent food particles and bacteria from settling into the grooves and crevices where they can cause cavities.
• Avoid Smoking: The restricted blood flow that can be caused by smoking weakens gums, making them more likely to recede and expose sensitive tooth roots.
• Opt for Sugar-Free Candies and Gum: Satisfy your sweet cravings with options made without sugar to stimulate saliva and protect teeth.
