What was the last time you headed out to a coffee shop or restaurant with your friends in a jovial mood, only to return with a grimace on your face? Everything seemed perfect until the moment you took a sip of Pina Colada, and you felt a sharp twinge in your teeth. And since then, your sensitive teeth have refrained you from consuming your favourite drink.

The sudden pain you felt when sipping the drink was due to teeth sensitivity to cold. It is a common dental problem in Australia, and may stem from a range of underlying problems in the tooth structure. 

If you’re cautious about tooth sensitivity and want to learn in detail about its causes and treatments, this blog is for you. 

What Is Tooth Sensitivity?

Tooth sensitivity refers to the sudden pain felt when the dentin, exposed as a result of enamel breakdown, makes contact with hot or cold food. The dentin has tiny tubules that extend upto the center of the tooth where sensitive nerves are present. In case of sensitivity, the central area begins to receive the effects of different temperatures ( hot and cold), which manifest in the form of sudden pain or a wave of discomfort.

It is important to note that sensitivity isn’t solely the aftermath of enamel breakdown. Instead, it can be triggered by other, more serious dental problems as well. 

 

Common Causes Of Sensitive Teeth: 

Teeth Sensitivity is caused by several reasons related to the dental structure of the teeth. Understanding the underlying problems is pivotal to treating the issue at its root, rather than just suppressing pain for a brief duration. 

Enamel Wear and Erosion:

Enamel wear is one of the most prominent causes of tooth sensitivity. When this process takes place, the inner dentine becomes exposed to external stimuli, such as changes in temperature.

Enamel Wear and Tear Is Driven By Many Factors:

1- Consumption of Acidic Food And Drinks:

Refreshing your taste buds with occasional acidic drinks, such as coffee, soft drinks, sports drinks, and Pina Colada, is fine. But consuming these drinks regularly can raise the likelihood of damage to the tooth’s enamel. Acid present in these drinks weakens the enamel gradually, which results in vulnerability to teeth sensitivity.        

2- Bruxism:

Grinding or clenching teeth during the nighttime can result in gradual enamel wear or teeth shifting away from the gum. Both these factors can trigger teeth sensitivity.

Gum Recession: 

Gum recession plays its part in making the teeth sensitive. When this recession happens, roots with thin enamel are exposed to the effects of hot and cold food.  

Causes of Gum Recession        

 1- Gum Disease:

Gum diseases, when left unattended, lead to inflammation and whittling away at the gum mass, which increases the exposure to, particularly, cold foods.           

2- Aggressive Brushing:

Brushing too fast or too hard can aggravate the issue of tooth sensitivity by taking a toll on both enamel and gum tissue. When hard brushing is continued, teeth can become sensitive over time.

3- Age-Related Changes:    

Gum recession is also linked with increasing age. As time passes, the teeth undergo wear and tear, and the enamel and gum become weakened, which may cause sensitivity at later stages of life.

 

Dental Procedures

Although you may not know it, temporary sensitivity can also occur due to certain dental treatments. A newly treated tooth takes time to heal or adapt to a new position, and during this time, the tooth may show a little sensitivity.

    1- Fillings:               

Individuals may experience tooth sensitivity right after getting fillings, particularly when they come into cold temperatures.

 

    2- Teeth Whitening: 

Whitening products contain bleaching agents that can cause sharp discomfort temporarily, as they can make contact with the dentin.

    3- Dental Cleaning: 

Post dental cleaning, teeth may show sensitivity to hot and cold liquids in a short time. However, this type of sensitivity may resolve on its own with time.

Tooth Damage or Decay

When the tooth is structurally compromised, irritants get a chance to reach into the sensitive part of the tooth where nerves are present.

   Causes of Tooth Decay or Damage:

    1- Cracked Tooth:

Small cracks in teeth occured due to injuries or blows can trigger sensitivity during the chewing of food.

 

    2- Early-stage Cavities:

Cavities in teeth undermine the enamel, which allows cold liquids and foods to make direct contact with the dentin, causing sensitivity pain.

 

 What are Tooth Sensitivity Symptoms?

Tooth sensitivity can manifest in different ways depending on the underlying issue in the teeth. Additionally, the duration of sensitivity also governs the extent and nature of the problem that triggers this pain. 

    1- Sharp Pain Wth Cold or Hot Food:     

One of the most common signs of sensitive teeth is experiencing sharp pain while consuming hot or cold foods and drinks. This twinge occurs when the dentine is exposed to temperature differences that stimulate the sensitive tooth nerves. The duration of this discomfort is short; if not addressed, it may escalate with time.

    2- Discomfort While Brushing and Flossing:

Sensitivity-related pain can emerge during brushing or flossing the teeth. This pain is usually felt in the gumline and indicates that it has budged from its original position. More importantly, the intensity of this discomfort may escalate if the brushing is done aggressively. 

    3- Sensitivity To Acidic Or Sweet Foods:     

A tingling sensation when consuming sweet and citrus-based food suggests the presence of tooth sensitivity. It usually happens when the enamel of the teeth has become thin due to tooth decay, causing the food pigments to interact with the dentin. 

   Lingering Teeth Sensitivity vs Short-term Sensitivity

    Lingering Sensitivity Discomfort:      

If the sensitivity discomfort occurs frequently and persists, it may indicate a distinct underlying dental issue. Moreover, this condition requires prompt medical assistance from a dentist.

    Short-term Sensitivity

In case the pain lasts for a few seconds, it may signal common tooth sensitivity. 

 

   How Dentists Diagnose Teeth Sensitivity in Australia?

Since tooth sensitivity can stem from distinct causes, each one suggests a different underlying cause. That is why dentists in Australia conduct a proper diagnosis to figure out the exact reason for sensitivity, which helps in choosing the right treatment.

    1- Clinical Examination: 

A dentist commences with a detailed clinical examination of the dental structure, including teeth, gums, and surrounding tissues. This includes checking for signs of enamel wear, gum recession, decay, or worn dental restorations. When it is difficult to pinpoint the location of a sensitive tooth, the dentist may utilize gentle stimuli such as air or temperature to locate the source of discomfort precisely.

    2- Medical and Dental History:

The medical and dental history plays an important part in determining the cause of sensitivity and the treatment to resolve it. To obtain this data, the dentist may ask the patient the following questions:

– When did the sensitivity start?

– What are the sensitivity triggers as per your observation?

– Have you undergone any dental treatments recently?

– Do you follow oral hygiene practices?

– Do you have a teeth-grinding or clenching habit, particularly at night?    

Clear answers to these questions paint a clear picture of the extent of the problem.

   Identifying the Sensitivity Cause:

After giving medicine to temporarily relieve the sensitivity issue, the dentist aims to pinpoint the root cause. Once the dentist has reached the main cause, he will propose a treatment along with clinical instructions to manage sensitivity.

 

   Tooth Sensitivity Treatment Options In Australia          

Treatment of tooth sensitivity varies with its intensity, cause, and frequency. However, dentists in Australia recommend a few at-home tips to manage its symptoms for a short time, and suggest signs about when to visit a clinic for proper treatment.  

   Tips To Manage Sensitive Teeth At Home

For an individual experiencing mild to moderate sensitivity symptoms, there are certain measures to alleviate the discomfort and prevent it from worsening:

    1- Densensitising Toothpaste:  

Toothpastes formulated to alleviate or resolve sensitivity contain ingredients that block the nerve signal over time. Once these nerves are desensitised, the patient will no longer feel sharp twinges while consuming hot or cold liquids. However, it is important to note that the desensitization process takes time and is not immediate after you brush your teeth using this toothpaste.

 

    2- Correct Brushing Technique: 

To manage sensitivity discomfort, it is crucial to use the correct brushing technique. First of all, use a soft-bristle toothbrush and move the brush gently over the teeth to prevent irritation and enamel wear. 

 

    3- Dietary Adjustments: 

The nature of the diet plays its part in managing tooth sensitivity. Cut down on the amount of soft drinks, citrus fruits, and sports drinks. Doing so will prevent sensitivity triggers and protect the enamel, thereby blocking the flow of food pigments into sensitive nerves.

 

   In-Clinic Dental Treatments:

Dental treatments are recommended when sensitivity doesn’t improve with in-home care remedies. In Australia, dentists suggest several dental treatments based on the nature of the underlying issue causing sensitivity.

    1- Fluoride Varnishes:  

The dentist applies to the tooth enamel to strengthen it; this also protects the exposed tooth surfaces and reduces sensitivity triggers.   

 

    2- Bonding or Sealants:

Another effective option to alleviate the symptoms of sensitivity is the use of bonding agents or sealants. When applied professionally, they help to lessen nerve stimulation and discomfort resulting from sensitivity. 

 

    3- Gum Recession and Treatments:

When receding gums begin to trigger sensitivity, targeted gum treatments assist in shielding the exposed roots. This protective shield reduces discomfort and improves comfort over time.

 

   How Long Does The Sensitivity Last? 

The duration of tooth sensitivity depends upon its intensity and the underlying cause that drives it. 

 

    1-Temporary Sensitivity:

The most prevalent type of teeth sensitivity lasts typically from a few days to 2-4 weeks. 

    2- Chronic Sensitivity: 

Chronic sensitivity refers to discomfort that may persist over several months. If left unattended, it may worsen with time, causing severe pain and discomfort. 

   Can Tooth Sensitivity Be Prevented? 

Tooth sensitivity can be avoided in many cases by adopting a good oral hygiene routine. However, some cases are unavoidable and require expert assistance to resolve them.

 

    Daily Oral Habits:

– Brush twice a day gently with a soft-bristle toothbrush with the right technique

– Floss daily to prevent gum inflammation and recession. This also helps in removing the stuck particles between the teeth, which may lead to tooth decay.

– Replace toothbrushes every 3 months because their bristles fray in this duration.

– Choose desensitizing toothpaste containing potassium nitrate or stannous fluoride.    

– Reduce intake of acidic food and drinks( soft drinks, citrus and sportdrinks) 

– Regular Dental Check helps to catch sensitive areas early and prevent them from worsening with proper care and a restricted diet.

Frequently Asked Questions

Q1: How to alleviate tooth sensitivity?

Ans: To alleviate tooth sensitivity, use a desensitising toothpaste daily and brush gently with a soft-bristled toothbrush. Limit acidic foods and drinks, and avoid brushing immediately after consuming them.
Maintain good oral hygiene and see a dentist if sensitivity persists, as it may indicate an underlying issue.

 

Q2: How to cure a sensitive tooth?

Ans: A sensitive tooth isn’t always something you can “cure” at home, but it can often be managed and treated. Use a desensitising toothpaste, brush gently with a soft toothbrush, and reduce acidic food and drink intake.

If sensitivity persists, a dentist can treat the underlying cause (such as decay, gum recession, or enamel wear).

 

Q3: What causes random tooth sensitivity?

Ans: Common causes include early tooth decay, minor cracks, enamel wear, gum recession, sinus pressure, or recent dental work. It can also be triggered by teeth grinding (bruxism), which gradually wears down enamel, or by sudden temperature changes that expose sensitive dentine. In some cases, sensitivity may be an early warning sign of a developing dental issue that isn’t yet visible or painful.

 

Q4:- Can a sensitive front tooth heal on its own?

Ans: Mild sensitivity may improve with desensitising toothpaste and gentler brushing. Persistent sensitivity usually needs a dental assessment.

 

Q5:- Is tooth sensitivity normal after a filling?

Ans: Yes. Mild sensitivity after a filling is common and usually temporary as the tooth nerve settles. It may be noticeable when eating hot, cold, or sweet foods, or when biting down. This sensitivity usually improves gradually over a few days to two weeks. If it persists beyond this period or worsens, it’s important to have your dentist check the filling.
