Do you dread sipping hot coffee or biting into an ice cream? If so, you may be familiar with teeth sensitivity.It's a common dental issue that affects many people, causing discomfort and sometimes even pain.

What is teeth sensitivity?

teeth sensitivity, or dentin hypersensitivity, is a condition that arises when the enamel, which is the outermost protective layer of your teeth, deteriorates, revealing the underlying dentin layer. Within the dentin are minuscule tubules that link to the nerves in your teeth, rendering them more vulnerable to external stimuli like heat, cold, sweetness, or acidity.

Causes of teeth sensitivity

  •  Brushing too hard Aggressive brushing with a hard-bristled toothbrush or excessive force can lead to enamel erosion and gum recession, exposing the dentin.
  •  Gum recession When the gums recede, the tooth roots become exposed, leaving them vulnerable to sensitivity.
  •  Tooth decay Cavities or decay near the gumline can cause sensitivity, especially if they reach the dentin.
  •  Dental procedures Some dental treatments, such as teeth cleaning, whitening or fillings, can temporarily cause sensitivity.

Solutions for Teeth Sensitivity

  •  To prevent more damage to your enamel, it's best to use a toothbrush with soft bristles and brush gently with the correct strokes.
  •  Avoid high-acid foods and drinks to maintain strong tooth enamel. If consumed, rinse your mouth with water afterwards.
  •  Always practice good oral hygiene by regularly brushing and flossing to keep your teeth healthy.
  •  Use toothpaste specifically designed for sensitive teeth. These toothpastes contain ingredients that help block the tubules in the dentin, reducing sensitivity.
  •  Consider incorporating fluoride mouthwash or gels your dentist recommends into your oral care routine. These products can help strengthen your tooth enamel and alleviate sensitivity.
  •  If you grind your teeth, known as bruxism, use a mouth guard at night to protect your teeth from wear and tear.
  •  If you are experiencing tooth sensitivity, it is important to consult a dental professional to diagnose and address any potential dental problems contributing to your sensitivity, such as cavities or gum disease.


Sudden tooth sensitivity is often attributed to the thinning of tooth enamel, which serves as a protective outer layer for your teeth. When enamel wears down, the inner layer of the tooth gets exposed, and this can lead to increased tooth sensitivity and vulnerability to other dental issues.
Tooth sensitivity typically doesn't resolve on its own, especially if it stems from receding gum lines. It's usually an indicator of an underlying oral health problem that should be promptly addressed. Temporary relief from desensitising toothpaste may mask the symptoms but not the underlying ones.
To bolster your tooth enamel, consider the following practices: avoid acidic foods, opt for water over acidic beverages like soda or juice, use enamel-strengthening toothpaste, minimise the consumption of enamel-staining foods and drinks, maintain a balanced diet, ensure an adequate intake of fluoride, avoid DIY teeth-whitening remedies, and don't neglect the overall health of your mouth.
Following dental treatments like fillings, tooth sensitivity can emerge and gradually subside over a period of approximately 2 to 3 months. If the discomfort persists beyond this timeframe, it is advisable to consult your dentist for further evaluation.
Tooth sensitivity can be attributed to various factors, but the most common underlying reasons are enamel erosion, gum recession and deep carious decays. Enamel loss can result from factors like overly aggressive brushing and acid erosion caused by acidic foods and beverages, such as sugary sports drinks and sodas.
Low levels of vitamin D may exacerbate dental problems in adults, particularly periodontitis and gingivitis. In children, low levels of vitamin-D may lead to disturbances in tooth development and eruption.


In conclusion, tooth sensitivity, is a common dental problem affecting anyone. Understanding the causes and implementing proper oral hygiene practices can significantly reduce this discomfort. By taking proactive steps and seeking professional care when necessary, you can enjoy a pain-free smile and indulge in all your favourite foods and drinks without worrying about sensitivity.
