What’s Causing Your Tooth Sensitivity? 60sec Quiz

That sudden zing from cold water, hot coffee or biting into food can feel small at first, until it starts changing what you eat and drink.

Tooth sensitivity has more than one possible cause. For some people, it comes from exposed dentine near the gumline. For others, it may point to decay, a cracked tooth, inflammation inside the tooth, gum problems, grinding, or a recent dental treatment.

This quick quiz takes around 60 seconds. It can help you understand what may be contributing to sensitive teeth, but it does not diagnose dental disease.

If your symptoms are severe, persistent, spontaneous, associated with swelling, or painful when biting, please see your dentist.

Cold drinks are a common trigger for sensitive teeth.

Before you start

For each question, answer:

• Yes

• No

• Not sure, where offered

  
  

Keep track of your “yes” answers. The pattern matters more than the total number.

This quiz is for general information only. Dental symptoms can overlap, and only a dental examination can confirm what is happening.

Question 1

Do your teeth hurt when you have something cold?

Examples include cold water, ice cream, refrigerated foods, or breathing in cold air.

Yes / No

What this can mean

A brief, sharp response to cold is one of the classic patterns seen with exposed dentine and dentine hypersensitivity.

Dentine sits beneath the hard enamel and root surface. It contains tiny tubules that can transmit sensations towards the nerve inside the tooth. When dentine is exposed, cold can trigger a quick, sharp pain.

This type of sensitivity often feels like:

• A sudden zing

• Pain that lasts only a few seconds

• A trigger that is easy to identify

• Discomfort near the gumline

  
  

Cold sensitivity can also occur with tooth decay, leaking fillings, cracked teeth, or recent dental work, so context matters.

Question 2

Do your teeth hurt with hot food or drinks, particularly if the pain lingers afterwards?

Yes / No

What this can mean

Sensitivity to heat, especially pain that persists after the heat is removed or happens on its own, can sometimes indicate inflammation within the tooth rather than simple dentine sensitivity.

This may feel different from a quick cold zing. Heat-related pain may be deeper, duller, throbbing, or longer lasting.

We recommend a dental examination, especially if the pain:

• Lingers for more than a short moment

• Wakes you at night

• Happens without a clear trigger

• Feels like it is coming from one specific tooth

  
  

Simple sensitivity usually responds to a trigger and settles quickly. Lingering heat pain needs proper assessment.

Lingering pain after hot drinks needs more attention.

Question 3

Does a tooth hurt when you bite, chew, or release your bite?

Yes / No

What this can mean

Pain with biting or pressure can have several causes. These include:

• A cracked tooth

• A damaged or high filling

• Inflammation around the tooth

• Gum disease

• Excessive forces from clenching or grinding

  
  

Pain when releasing your bite can be a clue that a crack or pressure-related problem may be involved. It can also happen when the ligaments around a tooth are irritated.

We recommend having the tooth examined by a dentist. Biting pain is not the usual pattern for simple dentine hypersensitivity.

Question 4

Do you have swelling around the tooth, gum, or face?

Yes / No

What this can mean

Swelling can be associated with inflammation or infection. It is not typical simple dentine hypersensitivity.

Please arrange a dental assessment promptly.

Seek urgent care if swelling is:

• Rapidly increasing

• Associated with fever

• Making it hard to swallow

• Making it hard to breathe

• Spreading towards the eye, jaw, or neck

  
  

Swelling should not be managed with sensitivity toothpaste alone. It needs professional assessment.

Question 5

Can you see exposed tooth roots, or have your gums receded?

Yes / No / Not sure

What this can mean

Unlike enamel, root surfaces are not designed to handle the same level of temperature, brushing, and dietary acid exposure. When gums recede, the root surface may become exposed. This can make the tooth more sensitive, especially to cold air, cold drinks, brushing, or sweet foods.

Gum recession may look like:

• Teeth appearing longer than before

• Yellowish areas near the gumline

• Notches close to the gum

• Sensitivity in one area when brushing

• Spaces or “black triangles” between teeth

  
  

Recession can be linked with gum disease, tooth position, past orthodontic treatment, clenching, grinding, or brushing technique. A dentist or dental hygienist can check whether recession is stable or still progressing.

Question 6

Do acidic foods or drinks trigger the sensitivity?

Examples include soft drinks, sports drinks, citrus, vinegar, wine, kombucha, or frequent lemon water.

Yes / No

What this can mean

Acid can soften the outer tooth surface and contribute to enamel wear over time. When enamel thins or root surfaces are exposed, teeth may become more sensitive.

This does not mean you need to avoid every acidic food. The pattern matters. Frequent sipping or grazing is usually harder on teeth than having acidic foods or drinks with a meal.

Helpful habits include:

• Drinking water after acidic drinks

• Avoiding brushing straight after acidic foods or drinks

• Using a straw for acidic cold drinks, where practical

• Keeping acidic drinks to mealtimes rather than sipping over hours

  
  

If sensitivity is linked with acid wear, the focus is usually on reducing frequency, protecting the tooth surface, and checking for any underlying causes such as reflux or dry mouth.

Acidic foods and drinks can contribute to enamel wear.

Question 7

Do your teeth feel sensitive when brushing or after brushing?

Yes / No

What this can mean

Sensitivity during brushing can happen when dentine is exposed at the gumline, when gums are inflamed, or when the tooth surface has been worn.

Brushing harder does not clean better. It can irritate the gums and wear exposed root surfaces over time.

Try these basics:

• Use a soft toothbrush

• Brush gently along the gumline

• Use small circular motions

• Avoid scrubbing side to side

• Spit after brushing rather than rinsing heavily, especially when using fluoride toothpaste

  
  

If you already use a sensitive toothpaste, give it consistent time to work. Many products need regular use, not just occasional use when symptoms flare.

Question 8

Have you recently whitened your teeth, had dental treatment, or started using a new toothpaste?

Yes / No

What this can mean

Short-term sensitivity can happen after whitening, dental cleaning, fillings, crowns, or other dental treatment. It can also happen after switching to a toothpaste that feels more abrasive or strongly flavoured.

This sensitivity often improves, but it should not become severe or keep getting worse.

Contact your dentist if:

• The pain is increasing

• One tooth feels much worse than the others

• The sensitivity lasts longer than expected

• You have pain when biting

• You notice swelling or a bad taste

  
  

Recent dental work can make a tooth feel temporarily different. Persistent pain still deserves a check.

Question 9

Do you clench or grind your teeth?

Signs may include jaw tightness, morning headaches, worn tooth edges, chipped teeth, or a partner noticing grinding sounds.

Yes / No / Not sure

What this can mean

Clenching and grinding can place heavy forces on teeth. Over time, this may contribute to cracks, gumline wear, tooth mobility, jaw muscle pain, and sensitivity.

Some people grind at night and have no idea. Others clench during the day when concentrating, driving, exercising, or feeling stressed.

A dentist can look for signs of excessive forces and may discuss options such as:

• A custom night guard

• Repairing worn or cracked teeth

• Adjusting high fillings

• Jaw muscle management

• Habit awareness during the day

  
  

If biting pain is part of the picture, do not assume it is only grinding. A crack, filling issue, or inflamed tooth also needs to be ruled out.

Question 10

Does sweet food trigger a sharp or localised pain?

Examples include chocolate, lollies, sweet drinks, biscuits, or dried fruit.

Yes / No

What this can mean

Sweet sensitivity can occur with exposed dentine, but it may also suggest tooth decay, a leaking filling, or a gap where bacteria can collect.

Pay attention to whether the pain is:

• In one specific tooth

• Getting worse over time

• Triggered by both sweet and cold

• Associated with food catching

• Linked with a visible dark spot or broken edge

  
  

If sweet sensitivity feels localised to one tooth, a dental check is sensible.

How to read your answers

Your answers may point towards more than one possible cause. Use the guide below to understand the pattern.

Your pattern	What it may suggest	What to do next
Cold causes a brief, sharp zing that settles quickly	Exposed dentine or dentine hypersensitivity	Use a sensitive toothpaste consistently and book a routine dental check
Heat pain lingers or happens spontaneously	Possible inflammation inside the tooth	Arrange a dental examination
Pain happens when biting, chewing, or releasing your bite	Crack, filling issue, gum problem, inflammation, or grinding forces	Have the tooth examined
Swelling is present	Possible infection or significant inflammation	Seek dental assessment promptly
Gums have receded or roots are visible	Exposed root surfaces	Ask your dentist or hygienist to check gum health and brushing technique
Acidic foods or drinks trigger symptoms	Enamel wear or exposed dentine may be involved	Reduce acid frequency and discuss prevention
Brushing triggers pain	Gumline sensitivity, recession, or worn tooth surfaces	Use a soft brush and gentle technique
Whitening or recent treatment started the symptoms	Temporary post-treatment sensitivity may be possible	Monitor briefly, but call your dentist if it worsens
Grinding signs are present	Heavy forces on teeth and supporting tissues	Ask about tooth wear, cracks, and a night guard
Sweet foods trigger one tooth	Decay, exposed dentine, or a leaking filling	Book a dental check

When sensitivity is more likely to be dentine hypersensitivity

Dentine hypersensitivity has a fairly typical pattern. It is often:

• Sharp

• Brief

• Triggered by cold, touch, air, sweet foods, or brushing

• Located near the gumline

• Not associated with swelling

• Not usually painful when biting

  
  

It often happens when dentine becomes exposed due to gum recession, enamel wear, acid exposure, or tooth surface loss.

Sensitive toothpaste can help many people with this pattern. Different products work in different ways, such as helping block dentine tubules or calming nerve response. Consistent use matters. Some people also benefit from fluoride treatments, protective coatings, changes to brushing technique, or treatment for gum recession.

When tooth sensitivity needs a dentist sooner

Do not wait and hope it settles if your symptoms suggest something more than simple sensitivity.

Book a dental appointment if you notice:

• Lingering pain after hot or cold

• Spontaneous pain with no trigger

• Pain that wakes you at night

• Pain when biting or chewing

• Swelling around the gum, jaw, or face

• A cracked tooth or broken filling

• Sensitivity in one specific tooth that is getting worse

• Bad taste, pus, or a pimple-like swelling on the gum

  
  

These signs can point to problems that need diagnosis and treatment, not just desensitising toothpaste.

Good daily habits can reduce some forms of tooth sensitivity.

What you can do today

If your symptoms are mild, brief, and mostly triggered by cold or brushing, these steps may help while you arrange routine care:

1. Brush with Eviwelle Toothpaste daily

   
   

   Eviwelle is less abrasive than most toothpaste. It contains potassium ions and nano-hydroxyapaptite both proven to reduce tooth sensitivity. Brush with it twice a day. For a very sensitive spot, some people apply a small smear with a clean finger before bed. Follow the product directions.

   
   

2. Switch to a soft toothbrush

   
   

   A soft brush is enough to clean teeth when used well. Avoid firm scrubbing, especially near the gumline.

   
   

3. Watch acidic drink habits

   
   

   Try not to sip acidic drinks over long periods. Rinse with water afterwards and wait before brushing.

   
   

4. Do not ignore one-tooth pain

   
   

   Sensitivity across several teeth often has a different meaning from pain in one specific tooth. Localised pain deserves a closer look.

   
   

5. Mention grinding or clenching

   
   

   If you wake with jaw tightness or notice worn teeth, tell your dentist. Bite forces can affect sensitivity and tooth cracks.

   
   

Your quick result

If most of your “yes” answers were to cold, brushing, gum recession, or acidic triggers, exposed dentine may be part of the story.

If you answered “yes” to heat that lingers, biting pain, swelling, spontaneous pain, or one specific tooth getting worse, book a dental examination. These symptoms can point to causes that need professional diagnosis.

Tooth sensitivity is common, but it is not all the same. The safest next step is to match the pattern, protect your teeth day to day, and get a dentist to check anything that feels severe, persistent, or unusual.
