Understanding Teeth Sensitivity

Dentinal hypersensitivity or tooth sensitivity is a common dental problem. Most sufferers are between 20 and 50 years old

Some Of The Most Common Triggers For Tooth Sensitivity:

  • Brushing teeth
  • Breathing in cold air
  • Eating sugary or sour foods
  • Eating hot food or drinking hot drinks
  • Eating cold food or drinking cold drinks

What Causes Sensitive Teeth?

Tooth sensitivity occurs when the layer of a tooth underneath the enamel (called the dentin) or the layer covering the root (called cementum) is exposed along the gum line due to receding gums. The exposed areas respond to hot and cold and sometimes too sweet and spicy foods and trigger pain. Thousands of microscopic channels run through the dentine towards the centre of the tooth. Once the dentine is exposed, external triggers (such as a cold drink) can stimulate the nerves inside the tooth, causing the characteristic short, sharp sensation of tooth sensitivity.

Common Causes Of Dentinal Hypersensitivity Or Teeth Sensitivity:

Enamel wear e.g. from tooth grinding or frequent tooth brushing

Gum recession e.g. from gum disease or aggressive brushing with hard bristle brush

The sensitivity which can be experienced during and after professional tooth whitening (bleaching) treatments is different from dentinal hypersensitivity.

What Causes Enamel Wear?

Enamel is the thin outer covering of the tooth. This tough shell is the hardest tissue in the human body. Enamel covers the crown which is the part of the tooth that is visible outside of the gums. Although it’s harder than any other substance in the body, over time it can gradually wear away to expose the dentine beneath, which may lead to tooth sensitivity.

What Is Teeth Grinding?

Bruxism is a condition in which you grind, gnash or clench your teeth. If you have bruxism, you may unconsciously clench your teeth when you’re awake (awake bruxism) or clench or grind them during sleep (sleep bruxism). It is basically non-functional grinding of teeth, which over time can expose the underlying dentine.

Acid Erosion Of Tooth Surface

Dental erosion is the loss of the surface of your teeth due to acids you eat or drink or acids coming up from your stomach. These acids can dissolve the crystals that make up your teeth, leading to tooth surface loss.
Acidic foods and drinks include fruit and fruit juices, carbonated drinks, black coffee or tea, wine, and anything that tastes sharp such as ketchup or salad dressing. As few as four acidic ‘challenges’ throughout the day can put your enamel at risk from acid erosion, also known as acid wear.

Link Between Excessive Teeth Brushing And Sensitive Teeth

If you brush too frequently or too hard, eventually your tooth enamel may be worn away or you could develop receding gums.

To prevent this ask your dentist for advice on the best tooth brushing technique and oral hygiene routine for you and try using a soft-bristled toothbrush.

Gum Health And Sensitivity

Healthy gums are essential for healthy teeth. Gum recession is one of the leading causes of tooth sensitivity. Overly frequent or aggressive tooth brushing, long term gum disease (gingivitis or periodontal disease) and even ageing can contribute to gum recession. As the gums recede, the underlying dentine can gradually become exposed over time and may lead to tooth sensitivity.

Some Dental Problems That Mimic Tooth Sensitivity:

Tooth Decay

Sensation caused by tooth decay can feel similar to tooth sensitivity. Tooth decay happens when the sugars in foods and drinks react with the bacteria in the plaque on our teeth to form acids. These acids can gradually soften and dissolve your enamel and dentine exposing pulp, which causes tooth sensitivity.
The problem with tooth decay is that you might not feel any sensation from it until it’s quite advanced. It can be managed in the early stages. So, even if you don’t feel any sensation, it’s important to go for regular dental checkups so that your dentist can spot early signs of tooth decay and work with you to manage it.

Tooth Sensitivity After Dental Treatment

It is not uncommon for your teeth to feel sensitive for a time after having dental treatment. However, if this persists contact your dentist for advice.
Other common causes of tooth discomfort include dental abscesses and cracked or fractured teeth. It is important to visit your dentist regularly to check the health of your teeth and gums. If you feel any discomfort, particularly if it persists, contact your dentist for advice.

Do Teeth Whitening Treatments Cause Sensitivity?

The sensitivity which can be experienced during and after professional whitening procedures is different from dentinal hypersensitivity. Dentinal hypersensitivity is a common condition of the teeth which can arise when the dentine of the tooth becomes exposed (typically as a result of gingival recession or tooth wear). However, in the case of whitening treatments, the bleaching component of the treatments is believed to penetrate the tooth, reaching dentine and causing sensitivity.
Clinical studies indicate that toothpastes containing potassium nitrate can reduce the sensitivity associated with professional whitening procedures. In these studies, subjects using toothpaste with potassium nitrate for two weeks prior to and during whitening treatment experienced less sensitivity post treatment, compared to those using a regular fluoride toothpaste.
Speak to your dentist about bleaching-related sensitivity if you are considering having a tooth whitening treatment.
