Why Are My Teeth Sensitive?
# Why Are My Teeth Sensitive?
Experiencing dental sensitivity can really disrupt your day-to-day activities. If you've been noticing your teeth becoming sensitive, you might be curious about what could be causing it.
In this article, we'll explore why teeth become sensitive, the typical symptoms of sensitive teeth, and how you can ease the discomfort. We'll also delve into some common triggers of sensitive teeth and ways to alleviate the associated pain.
## What Causes Teeth Sensitivity?
Teeth sensitivity usually stems from worn-out tooth enamel. Several factors can contribute to this:
### 1. Improper Brushing Techniques
Surprisingly, your brushing habits could actually lead to tooth sensitivity! Applying excessive force while brushing can be detrimental. Brushing too hard may increase your chances of developing sensitivity issues.
While your intentions may be good, brushing too vigorously can wear down the enamel, exposing the inner layer of dentin. This exposure often results in heightened sensitivity to hot and cold stimuli.
Using a toothbrush with hard bristles can have similar effects. It's advisable to switch to a toothbrush designed specifically for sensitive teeth. Additionally, using a toothpaste formulated for sensitive teeth can offer protection for both your teeth and gums.
### 2. Teeth Whitening
Teeth whitening treatments can effectively remove stains and discoloration. However, they may also lead to temporary tooth sensitivity. Some individuals may already have existing sensitivity issues that prevent them from undergoing whitening procedures.
Although the exact reason behind whitening-induced sensitivity isn't fully understood, it's believed that whitening agents can make teeth more porous. This exposes the delicate layer of dentin, resulting in sensitivity.
### 3. Periodontal Disease
Periodontal disease, also known as gum disease, is a severe infection affecting gum tissues. It arises due to a high concentration of bacteria both above and below the gum line.
As these bacteria thrive, they gradually erode gum, tooth, and bone structures over time. This leads to significant gum and bone recession. Gum disease also raises the risk of tooth decay as the protective enamel layer wears away. Consequently, it may cause increased tooth sensitivity for some individuals.
### 4. Consuming Acidic Foods and Drinks
The food and drinks we consume directly impact our dental health. Eating or drinking highly acidic items can wear down enamel, increasing the likelihood of tooth sensitivity.
Examples of acidic foods and beverages include:
- Soda and energy drinks
- Sweetened tea
- Citrus fruits
- Tomatoes
- Processed meats
- Grains
- Dairy products
- Nuts
It's best to avoid acidic foods and drinks whenever possible. If you do consume them, brushing immediately afterward can help prevent harmful acids from lingering on your teeth or gums.
### 5. Tooth Sensitivity Post-Filling
If you recently had a filling and are experiencing sensitivity, you might wonder why. After all, fillings are meant to protect and repair teeth, right?
It's perfectly normal to feel sensitive after a dental filling. The procedure can irritate or inflame the tooth's central nerve, particularly with larger fillings.
How long does tooth nerve sensitivity last after a filling? While it varies, sensitivity typically diminishes within a few days. As the filling settles and the nerve heals, discomfort should decrease.
To minimize or avoid post-filling sensitivity, consider the following:
- Avoid extremely hot or cold foods and beverages.
- Steer clear of acidic or sugary items.
- Maintain good oral hygiene practices.
- Refrain from chewing on hard or sticky substances.
### 6. Recent Dental Procedures
Other dental procedures, such as root canals and crown placements, may also cause sensitivity. Here's why:
- **Root Canal:** A root canal is necessary when the central nerve of a tooth is damaged or infected, often due to significant decay or trauma.
During the procedure, the dentist removes decay and extracts the nerve before replacing it with synthetic material. The tooth is then filled and sealed. Such procedures often lead to temporary sensitivity.
- **Crown or Bridge Preparation:** This involves removing decay and placing a large filling. In some cases, a root canal precedes crown or bridge installation.
The tooth is reshaped on all sides to accommodate the crown or bridge, which is then cemented in place. These procedures are invasive, so sensitivity afterward is common.
### 7. Why Are My Teeth Sensitive to Cold?
The central nerve of a tooth allows it to perceive sensations. When this nerve is exposed, you may feel sensitivity or pain. While cold temperatures often trigger sensitivity, heat can also do so.
Here are some reasons for tooth sensitivity to hot or cold:
- Tooth decay
- Periodontal disease
- Harsh brushing habits or hard-bristled toothbrushes
- Exposed central nerve due to extensive damage or decay
- Dental fluorosis
## How to Relieve Sensitive Teeth
Sensitive teeth can be uncomfortable and even painful. Fortunately, there are steps you can take to alleviate this issue.
Effective methods to relieve tooth sensitivity include:
- Using desensitizing or sensitive toothpaste
- Rinsing with hydrogen peroxide
- Rinsing with warm salt water
- Applying vanilla extract directly to the affected area
If you're in pain, over-the-counter medications like Tylenol or Ibuprofen can help manage discomfort.
### Specialized Mouthwash and Toothpaste for Sensitive Teeth
The toothpaste and mouthwash you use daily play a crucial role in maintaining tooth enamel health. Luckily, you have numerous options to safeguard your sensitive teeth.
Sensitive toothpaste contains potassium nitrate, a clinically proven ingredient that significantly reduces sensitivity. Consistent use strengthens enamel and provides long-term protection. Look for brands like Crest Pro-Health Sensitive and Gum Toothpaste or Sensodyne Sensitivity and Gum Toothpaste.
Mouthwash for sensitive teeth numbs the mouth slightly and applies restorative minerals to teeth. Listerine Sensitivity Zero Mouthwash is a great option.
### When to Visit Your Dentist for Tooth Sensitivity
While many cases of sensitivity resolve on their own, there are situations where immediate dental attention is essential.
Seek professional help if:
- Sensitivity persists for several days.
- Discomfort continues weeks after a dental procedure.
- Pain progresses from mild to unbearable.
- You notice swollen or tender gums or visible damage/decay.
Your dentist will conduct an examination to determine the root cause and create a personalized treatment plan to address the issue and restore comfort.
