How to Deal with Sudden Tooth Sensitivity

Ever felt that zing in your teeth when you take a sip of something hot or cold? Tooth sensitivity can turn simple pleasures like enjoying a hot drink into a painful experience. While a bit of sensitivity is normal, if it's happening often, it's time to pay attention.

In this blog, we're going to talk about sudden tooth sensitivity – something that's more common than you might think. From the factors promoting it to treatment plans, we’ll give you a run on all the highlights. So, if you're tired of wincing every time you bite into something sweet or sip a cold drink, stick around. We've got you covered. Let's get started.


Causes of Sensitive Teeth

Causes of Sensitive Teeth

Sensitive teeth can throw a wrench into your daily routine, making simple activities like enjoying a hot drink or biting into something sweet a painful experience. Understanding what causes tooth sensitivity is the first step toward finding relief. Let's unearth the main causes behind this discomfort-

Thin Enamel- Enamel acts as the protective shield for your teeth, but some people naturally have thinner enamel than others due to genetics. When enamel wears down, whether through genetics or other factors, the underlying dentin becomes exposed, leading to sensitivity to hot, cold, acidic, and sweet foods.

Grinding Teeth- Clenching or grinding your teeth, often a response to stress or frustration, can wear down enamel and lead to tooth sensitivity. This habit, known as bruxism, may also be related to jaw misalignment or certain medications. Using a nightguard or mouthpiece can help alleviate symptoms by providing cushioning between your teeth and preventing further wear.

Brushing Too Hard- While good oral hygiene is essential, brushing your teeth too vigorously can do more harm than good. Applying excessive pressure can wear down enamel and expose sensitive dentin. Opt for a soft-bristled toothbrush and gentle brushing technique to protect your enamel while maintaining oral health.

Acidic Foods and Drinks- Consistently consuming acidic foods and drinks can erode enamel over time, making your teeth more prone to sensitivity. Limiting your intake of acidic foods and beverages, such as citrus fruits and sodas, can help preserve enamel and reduce sensitivity.

Fractured Tooth- Even small cracks or abrasions on your teeth, known as "cracked tooth syndrome," can cause significant pain and sensitivity. These cracks may be difficult to see but can lead to discomfort when eating or drinking. Treatment options vary depending on the severity and location of the fracture, ranging from bonding to root canal therapy.

Tooth Decay- Tooth decay occurs when bacteria break down enamel and dentin, leading to cavities. Left untreated, decay can progress and cause sensitivity as the protective layers of the tooth are compromised. Early detection and treatment, such as sealants or fillings, can prevent further damage and help with sensitivity.

Gum Recession- Periodontal or gum disease can cause gums to recede, exposing the roots of the teeth and leading to sensitivity. Inflammation and redness of the gum line may be early signs of gum disease, which, if left untreated, can result in increased sensitivity and discomfort. Desensitizing toothpaste, soft-bristled toothbrushes, and regular dental check-ups can help manage gum recession and prevent further complications.

Preventing Tooth Sensitivity

Preventing Tooth Sensitivity

Nobody likes the discomfort brought on by sensitive teeth, so taking steps to prevent it is key. Here are some simple habits you can adopt to keep tooth sensitivity at bay-

Gentle Brushing Routine- Start your day by brushing your teeth gently with a soft-bristled toothbrush. Harsh scrubbing can wear down enamel over time, so opt for gentle strokes to clean your teeth effectively without causing damage.

Daily Flossing- Don't skip out on flossing! Removing plaque and debris from between your teeth helps prevent gum disease and tooth decay, both of which can contribute to sensitivity.

Right Toothpaste- Choose a toothpaste that is exclusively designed to strengthen enamel and protect against sensitivity. Purexa herbal toothpaste seals open dentinal tubules and reduces tooth sensitivity. It is manufactured using herbal ingredients that help build the enamel and prevent teeth from further decay.

Mindful Eating and Drinking- Be conscious of your diet and try to limit acidic foods and drinks that can erode enamel. Soft drinks, citrus fruits, and vinegar-based dressings are common culprits. Opt for water or milk instead and rinse your mouth with water after consuming acidic foods to help neutralize acids.

Protective Mouthguard- If you grind your teeth, especially at night, consider using a mouthguard to protect your teeth from excessive wear. A custom-fitted mouthguard from your dentist can provide cushioning and prevent enamel erosion caused by grinding.

Regular Dental Check-ups- Don't forget to schedule regular dental check-ups and cleanings. Your dentist can identify early signs of tooth sensitivity and provide personalized recommendations to address any issues before they worsen.

Treatment for Sudden Tooth Sensitivity

Treatment for Sudden Tooth Sensitivity

Dealing with sudden tooth sensitivity can be uncomfortable, but there are effective treatment options available. Whether you're experiencing mild discomfort or more severe pain, here are some ways your dentist may recommend addressing sudden tooth sensitivity-

Desensitizing Toothpaste- Start with an over-the-counter desensitizing toothpaste, such as Purexa herbal toothpaste, which contains ingredients like spinach, rhubarb root, arnica, and licorice. Purexa herbal toothpaste comes infused with the power of Ayurveda and the purity of organic ingredients that help care for your mouth naturally.

At-Home Remedies- Alongside desensitizing toothpaste, consider using a mouth rinse with lower acidity to further soothe sensitive teeth. Additionally, switching to a softer toothbrush and practicing gentle brushing techniques can help prevent further enamel wear and discomfort.

In-Office Treatments- If over-the-counter options don't provide sufficient relief, your dentist may recommend in-office treatments that address your specific needs. These may include-

  • Fluoride Gel Application- Your dentist can apply a fluoride gel to strengthen tooth enamel and reduce sensitivity.
  • Dental Restorations- Fillings, crowns, inlays, or bonding can be used to repair exposed tooth surfaces and reduce sensitivity.
  • Gum Grafts- If gum recession is the underlying cause of sensitivity, your dentist may suggest a gum graft to cover exposed tooth roots and reduce discomfort.
  • Root Canal Therapy- In severe cases where the tooth's pulp is affected, root canal therapy may be necessary to remove damaged tissue and reduce pain.
  • Pain Management- For mild discomfort, over-the-counter pain medication can provide temporary relief while waiting for other treatments to take effect. It's essential to follow your dentist's recommendations for pain management and treatment.


Dealing with sudden tooth sensitivity can be a real pain, but the good news is, there are ways to tackle it head-on. Whether it's switching to a gentler toothbrush, trying out desensitizing toothpaste, or exploring in-office treatments with your dentist, there's no shortage of options to ease the discomfort.

Remember, prevention is the best medicine. By practicing good oral hygiene and being mindful of what you eat and drink, you can reduce the chances of sensitivity creeping up again in the future.

So, don't let tooth sensitivity hold you back from enjoying life's simple pleasures. Take charge of your oral health, consult with your dentist, and enjoy that scoopful of ice cream!
