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.

Frequently Asked Questions About Sensitive Teeth
The fastest way to get relief at home is to gently rub a desensitizing toothpaste directly onto the sore tooth. Products like DARLIE Expert Gum Care Sensitivity Relief contain special ingredients that quickly calm the nerve pathways causing your discomfort. Leave it on for a few minutes before rinsing to let it work its magic. For a permanent fix, you should always schedule a checkup with your dentist.
Sudden sensitivity usually happens when your protective tooth enamel wears down or your gums recede, exposing the softer inside of the tooth. This can be triggered by a cracked tooth, a loose filling, or even brushing too hard with a stiff toothbrush. Changes in your habits, like eating more acidic foods or grinding your teeth at night, can also cause this sharp pain. If the ache appears out of nowhere, it is highly recommended to have a dentist check it out.
You can prevent sensitivity by being gentle with your teeth and maintaining a great daily oral care routine. Always use a soft-bristled brush, like the DARLIE High Density toothbrush, and avoid scrubbing too hard to protect your delicate enamel. Try to cut back on highly acidic drinks like soda, and consider wearing a mouthguard at night if you tend to grind your teeth. Using a fluoride toothpaste daily will also help keep your enamel strong and pain-free.
It is very common for a tooth to feel sensitive to hot or cold temperatures for a few days after getting a new filling. The dental work can temporarily irritate the delicate nerve inside your tooth, causing a brief ache when you eat. This discomfort should gradually fade on its own as the tooth heals and settles down. If the pain is sharp when you bite down or lasts longer than two weeks, contact your dentist to ensure the filling fits perfectly.
Yes, using an alcohol-free fluoride mouthwash is a wonderful way to help soothe and protect sensitive teeth. Harsh, alcohol-based rinses can sometimes sting or dry out your mouth, which might make your sensitivity feel much worse. It is important to understand the benefits of different formulas to choose the best mouth rinse option that will gently strengthen your enamel. Pair your chosen rinse with a dedicated sensitivity toothpaste for the best daily protection and comfort.
