Sensitive Teeth: Causes and How to Stop the Pain Immediately

If you experience sharp pain when consuming hot, cold, or sour foods or beverages, or even when breathing in cold air, it may be time to consult your dentist about possibility of sensitive teeth. Sensitive teeth, also known as dentin hypersensitivity, is a common dental issue affecting many people. In Singapore, nearly 80%¹ of the population experiences some form of gum disease, and dentists report that 4 out of 10 patients complain of sensitive teeth², emphasizing the prevalence and seriousness of this condition.

Reasons For Sensitive Teeth - Tooth Enamel Loss

Sensitive teeth are primarily caused by exposed dentine. When the enamel covering the tooth crown or the cementum and gum tissue on the root surface is worn away, the tooth loses its protective barrier, leading to exposed dentine. When this exposed dentine is stimulated by hot, cold, sour, or sweet foods and beverages, or even when brushed, a sharp pain is felt. This is why protecting tooth enamel is crucial for maintaining good oral health, as it serves as the first line of defense for your teeth.

What Causes Sensitive Teeth?

Sensitive teeth can be caused by various lifestyle habits and conditions that damage tooth enamel, causes poor gum health or expose the underlying dentine, resulting in discomfort and pain. Here are some common reasons:

1) Unhealthy Lifestyle Habits That Can Hurt Your Teeth

Brushing too hard

Brushing with excessive force or using a hard-bristled toothbrush can wear down the enamel, exposing the dentine and causing sensitivity. It is recommended to use a soft-bristled toothbrush and avoid brushing too vigorously.

Teeth grinding (bruxism)

Grinding your teeth can gradually wear away the enamel, leading to increased sensitivity.

Regular consumption of acidic food and drinks

Acidic beverages like soda, sticky candies, and high-sugar carbs can erode tooth enamel, leading to sensitivity. Limiting the consumption of these foods and rinsing after consuming these food & drinks can help protect your enamel.

Smoking

Smoking contributes to poor oral health and can worsen conditions such as gum disease, which increases sensitivity.

2) Poor Oral Hygiene

Gum disease

Plaque and tartar buildup can lead to gum disease, causing gums to recede and exposing the root of the tooth. This can increase sensitivity since the protective enamel is no longer sufficient.

3) Other Contributing Factors

Gum recession

Gum recession due to ageing, genetics, or gum disease can expose the roots of the teeth, which lack enamel protection and are therefore more sensitive to external stimuli.

Cracked teeth or fillings

Cracks in teeth or broken fillings can expose the sensitive parts of the tooth, leading to pain, particularly when consuming hot or cold foods and drinks.

Side effects of certain medications

Some medications may cause dry mouth or changes in saliva production, which can increase tooth sensitivity. Examples include antidepressants, diuretics (water pills), medicine for Parkinson’s disease, blood pressure tablets (betablockers) and inhalers can reduce salivary flow and increase the risk of suffering tooth decay.

Hormonal changes

Hormonal changes during pregnancy, menopause, or ageing can impact gum health and increase the likelihood of gum recession, contributing to sensitivity.

Understanding and addressing these underlying causes can help manage and reduce tooth sensitivity effectively. Adopting good oral hygiene habits and visiting your dentist regularly are key steps toward maintaining strong, healthy teeth and minimizing discomfort.

How to Treat Sensitive Teeth?

Here are some effective options:

1. Dental Adhesives or Sealants

Exposed root surfaces can cause long-term sensitivity and discomfort if left untreated. Dental adhesives or sealants provide a protective layer over the exposed area, minimizing discomfort by shielding the sensitive dentine from external stimuli.

2. Gum Graft

Gum recession can expose root surfaces, leading to increased sensitivity. A gum graft involves taking healthy tissue from another area of the mouth to cover the exposed roots, protecting them and reducing sensitivity.

3. Mouthguard

Teeth grinding (bruxism) can wear down the enamel, increasing sensitivity. Wearing a mouthguard, especially at night, helps protect the teeth from further damage, reducing sensitivity caused by grinding. Furthermore, to better protect your enamel, try not to brush too hard.
