What Causes Tooth Sensitivity and How to Manage It - 5 minutes read


Have you ever cringed while enjoying your favorite ice cream or sipping on a hot beverage? You're not alone. As Dr. Kevin Molldrem quotes, "Toothache is not a disease, but if ignored, it can cause serious problems." In fact, a recent study found that over 40 million adults in the United States alone suffer from tooth sensitivity. But fear not! In this guide, we'll look into the root causes of tooth sensitivity and provide basic yet effective ways to manage it, so you can indulge in your favorite treats without hesitation.


What is tooth sensitivity?

Tooth sensitivity is the state in which the nerves in your teeth become easily irritated by specific foods or drinks. It can make your teeth hurt suddenly, especially when you eat or drink certain things. Seeing a dentist can help, and there are things you can do at home to ease the discomfort. Sometimes, foods that are hot, cold, sweet, or spicy can make tooth sensitivity worse.


Symptoms of Sensitive Teeth

Sensitive teeth can cause pain or discomfort triggered by various things. You might feel the pain around the roots of your sensitive teeth. Common triggers include:


  • Hot or cold foods and drinks
  • Cold air
  • Sweet or acidic foods and drinks
  • Cold water, especially during dental cleanings
  • Brushing or flossing teeth
  • Mouth rinses with alcohol


These symptoms may vary in intensity and may come and go without a clear reason. If you experience sensitivity, it's essential to talk to your dentist for proper care and advice.


4 Common Reasons for Tooth Sensitivity

1. Gum Disease Can Cause Sensitive Teeth 

Your mouth is home to many bacteria, some of which can lead to infection and gum disease if not properly managed through regular dental care. Gum disease can start with red, swollen, and bleeding gums (gingivitis), which can progress to more serious issues affecting the gums, ligaments, and bone supporting your teeth. 


Once damaged, these tissues don't grow back. Bacteria can also cause gum recession, exposing the sensitive dentin of the tooth. Additionally, gum infections can spread through the bloodstream, affecting your overall health. Regular dental care can help prevent and treat gum disease.


2. Your Brushing Technique May Cause Sensitivity

Overbrushing or using abrasive toothpaste and hard brushes can damage your teeth and gums. Aggressive brushing can lead to gum recession and wear down the enamel on your teeth. When brushing, it's important to use a soft or extra-soft toothbrush and gentle circular motions to remove bacteria and debris without causing harm. Angling the brush towards the gums helps clean effectively while minimizing damage. By practicing mindful brushing, you can avoid causing sensitivity through forceful brushing.


3. Sensitivity Caused By Tooth Erosion

Tooth erosion occurs when the protective enamel of the tooth is weakened, exposing the sensitive inner layers. This can happen due to cavities formed by bacterial acid, aggressive brushing, frequent consumption of acidic foods and drinks, or conditions like acid reflux. 


Avoiding constant snacking and sipping acidic beverages throughout the day can help reduce erosion risk. Consuming acidic foods and drinks with meals and waiting to brush your teeth afterward allows saliva to neutralize acids and protect your enamel. Additionally, acidic foods should be consumed in one sitting to minimize exposure.


4. Can Clenching and Grinding Teeth Cause Tooth Sensitivity?

Clenching and grinding your teeth can put excessive pressure on them, leading to wear and sensitivity. Ideally, your teeth should only touch for about five minutes a day when swallowing. According to Dr. Kevin Molldrem, constant clenching or grinding, especially during sleep, can lead to enamel wear and gum recession. Symptoms like jaw pain, muscle tension, and headaches may indicate teeth clenching or grinding. Your dentist can create a custom night guard to help protect your teeth and ease your tense muscles while you sleep.


How to Ease Sensitive Teeth Pain

If you're dealing with sensitive teeth, there are steps you can take to find relief:


  • Desensitizing Toothpaste: Try using toothpaste made for sensitive teeth. Use it regularly, and you should start to feel less sensitivity. You might need to test a few brands to find the one that works best for you. Before bed, apply a thin layer of toothpaste to the sensitive areas.
  • Good Oral Hygiene: Keep up with your brushing and flossing routine. This helps keep your teeth and gums clean and healthy.
  • Soft-Bristled Toothbrush: Use a toothbrush with soft bristles to avoid irritating your teeth and gums.
  • Watch Your Diet: Limit acidic foods and drinks, as they can wear down your tooth enamel over time. This can worsen sensitivity and trigger pain.
  • Fluoridated Dental Products: Use mouthwash with fluoride to strengthen your teeth and decrease sensitivity. Ask your dentist for recommendations.
  • Mouth Guard for Teeth Grinding: If you grind or clench your teeth, wear a mouth guard at night to protect them.
  • Regular Dental Check-Ups: See your dentist for routine exams, cleanings, and fluoride treatments. They can catch any issues early and provide appropriate care.


If you're still experiencing discomfort, your dentist might suggest additional treatments, such as:

  • Dental Bonding: This involves applying a protective layer to cover exposed tooth roots.
  • Fluoride Varnishes: These are applied to sensitive areas to strengthen enamel.
  • Dentin Sealers: These sealants are applied to exposed tooth roots to reduce sensitivity.

Closing Remarks

So, to sum it up, tooth sensitivity can happen because of things like gum disease, brushing too hard, erosion, or grinding your teeth. Managing it means using special toothpaste, keeping your teeth clean, and being mindful of what you eat. Dr. Kevin Molldrem concluded that if the sensitivity persists, it is time to visit a dentist. They can figure out what's going on and help you feel better. Don't ignore it!
