If your answer is YES, you might be suffering from tooth sensitivity. Anyone who has experienced that sharp, biting sensation will agree that “Tooth sensitivity” sounds too harmless and too mild a word to describe this condition.
Tooth sensitivity is a common dental problem that affects almost 70% of people across the world. It refers to the sudden, shooting pain in the teeth on consuming very hot or cold foods and very sweet or sour foods. In extreme cases, a sip of cold water may also evoke the same reaction.* Data courtesy: Ambika Choudhary Mahajan, a lifestyle blogger who write for mymagicmix.com, a blog where you will find a refreshingly delicious chutzpah of information on a variety of topics including health.
Leading causes of tooth sensitivity
The basic underlying cause which brings about this condition is the wearing away of the hard, overlying layer of enamel on the teeth due to which the underlying softer parts (i.e. the pulp) gets exposed. Now, this pulp contains the sensory nerves of the teeth. When this area becomes exposed, the feelings of hot and cold, sweet and sour gets many magnified many times over, causing the sudden, jerking reaction in people suffering from this condition.
The 10 leading causes which cause the nerves of this area to be exposed are:
Receding of gums: Receding gums can be caused by advancing age, due to improper brushing techniques, vigorous or over enthusiastic brushing. When the gums recede, the dentine and the root of the tooth get bared leading to feelings of hot and cold, sweet and sour being blown out of proportion.
Gingivitis: Gum disease or gingivitis weakens the gums which hold the teeth in their place. As this worsens and causes inflammation of gums around the base of the tooth, the underlying root and nerves get exposed, leading to heightened sensitivity.
A cracked tooth: Any external crack on the surface of the tooth allows bacteria inside the mouth to find their way to the root of the tooth and cause an infection. Left untreated, it can become a cause of major headache later and cause hypersensitivity in a tooth or teeth.
Unhealthy eating habits: Whatever goes into your mouth affects your teeth before anything else. Consuming too many sweet and sticky foods (like chocolates, candies, ice- creams), food with acidic content (like pickles, strawberries), carbonated drinks like colas and very hot or very cold foods also takes a toll on the enamel present on the teeth and lead to tooth sensitivity over a period of time.
Bruxism: People who grind their teeth habitually or involuntarily (during sleep)- a condition called Bruxism- might also lose the hard enamel layer gradually and suffer from tooth sensitivity over a period of time.
Dental procedures: Some dental procedures like scaling of plaque, crown placement, tooth restoration, etc might lead to heightened sensitivity for a few days after the treatment. In most cases, sensitivity caused due to such procedure subsides on its own after few days without calling for medical intervention.
Using very hard toothbrushes with or without abrasive toothpastes: Using either or both of them has the same effect as sandpaper rubbing on wood. That is, thinning and wearing away of enamel on the surface of the teeth, thereby making them more prone to sensitivity.
Prolonged use of mouthwash: Most mouthwashes available in the market do indeed help make your breath fresher. But their acidic contents cause the erosion of enamel present on the surface of the teeth, making them weaker and also more vulnerable to tooth sensitivity.
Whitening treatments: We all love shining white teeth. So much so that the ones amongst us who have slightly paler ones go for expensive whitening treatments to get our pearls milky white. While that might help brighten up the smile, they cause untold damage to the enamel- which will make sure that you will be shedding tears for that later! If you must go in for whitening, make sure to check with the dentist about the damage caused to the tooth enamel.
Unusual medical conditions: At times, the acid content in the mouth might be extremely high due to medical conditions like GERD and bulimia. The high acid level in the mouth corrodes the enamel and makes the dentine more sensitive.
